Marine Biodiversity : A Global Pattern Essay
Marine biodiversity Definition: Marine biodiversity refers to the species richness and abundance of
genes, species and habitats in the world 's oceans and seas. And since the world is covered with
approximately 70% water the amount of life in the oceans is enormous. According to the definition
of the Convention on Biological Diversity, biodiversity is the variability among living organisms
from all sources, including inter alia, terrestrial, marine and other aquatic ecosystems and the
ecological complexes of which they are part; this includes diversity within species, between species
and of ecosystems.
Why Marine Biodiversity Is a global pattern: Biodiversity is essential for the benefits the
ecosystems can provide to humans. Biodiversity effects a larger number of plant species meaning a
greater variety of crops, greater species diversity and ensuring natural sustainability for all life
forms, food, medicinal resources and pharmaceutical drugs, wood products, ornamental plants,
breeding stocks, population reservoirs, future resources, diversity in genes, species. biological
diversity is the resource upon which families, communities, nations and future generations depend.
But we are currently using 25% more natural resources than the planet can sustain As a result
species, habitats and local communities are under pressure or direct threats and if we continue to
abuse this resources it will eventually be depleted and unuseable.

Biodiversity And Biodiversity
The current climate change is projected to have a significant influence over biodiversity. The
changes create risk to almost all the species on land to extinct by 2050. Due to earth's rapid
warming that is now faster than at any time in the past 10,000 years, the species survival is likely
to be at the fullest risk. The rapid heating temperature on earth almost always caused danger to
plants, animals, places and even people's livelihoods. It also damages the ecosystem, including
coral reefs, whole loss of unique forms of life that will create a complete disaster on earth. These
changes force the species to adapt to new climate patterns, if species can not evolve to live in a
certain ranges of temperature, or when it actually lives dependent to a certain temperature range,
then its existence is endangered. With the more intense rising of sea level and warmer ocean, the
prolonged period of a shortage of water resulted threaten crops, wildlife and storage of fresh water.
Various studies reveal that species usually move to higher elevations and latitudes in response to
climate change. The local extinction also record the loss of population at the warm edge of species
ranges that located in the lower elevations and latitudes. The data particularly show that roughly
half of the 976 species surveyed has extinct. Loss of species is normally happen in tropical region
across the climatic zones, habitats and group of organism. The species mostly are Earth's species

Big Idea Biodiversity
The big idea was biodiversity. Australian museum defines biodiversity as the "variety of all living
things; the different plants, animals and micro organisms, the genetic information they contain and
the ecosystems they form" (1). Within the big idea, biodiversity, the focus this term has been the
human impacts on ecosystems of Queensland. We have been looking towards making sustainable
practices to limit the human impacts globally on our ecosystems. According to nature works
organisation, ecosystem is a "community of living and non living things that work together.
Ecosystems have no particular size as it can be large as a desert or as small as a puddle" (2). 1.2

Biodiversity And Its Impact On Biodiversity
Biodiversity is what makes the planet earth unique and different from every other planet in the
solar system. Biodiversity can be studied on a global level all the way down to studying it within a
microscopic ecosystem (National Wildlife Federation, 2015). It is important to understand that
biodiversity can be looked at genetically as well as environmentally as well. For example, genetic
biodiversity is seen in the variation of different breeds within the dog species, while environmental
biodiversity is the diversity of ecosystems and habitats (National Wildlife Federation, 2015).
Preserving biodiversity is perhaps the most important task that humans have to complete while living
on this planet. The ecosystems that make up all of the regions worldwide are immensely complex,
so conservation may be difficult at times. Additionally, many factors influence the species that
inhabit ecosystems, and these factors may complicate the preservation of biodiversity. Moreover,
there is a plethora of threats to biodiversity, both natural and manmade that are destroying
ecosystems on a daily basis. Out of these threats, the human influences are particularly severe and
must be taken care of at all costs. Biodiversity provides countless benefits for every ecosystem and
creature, which is what makes it worthy of conservation. Through the introduction and relocation of
species, some degree of restoration may be possible in the future. Biodiversity is an amazing natural
process that makes life

"BIODIVERSITY"
Biodiversity, as defined by E.O. Wilson, "is meant to be all inclusive– it's the genetic based
variation of living organisms at all levels, from the variety of genes in populations of single species,
through species, on up to the array of natural ecosystems." This includes plants, animals,
insects, fungi, bacteria, and all microorganisms. All of these things create what is known as a web.
These things interact with each other in some way there for they depend on one another throughout
their lifetime. There are many separate ways in which we can study biodiversity. These ways
include, genetic, species, community, ecosystem, and taxonomic diversity. Biodiversity can be best

Areas that are very diverse are very important to humans as well. They provide a wide arrange of
pharmaceuticals such as aspirin and penicillin. "Some
40 percent of U.S. prescriptions are for pharmaceuticals derived from wild plants, animals and
microorganisms.(E.O. Wilson)" They also provide fruit, oils, beverages, drugs (including
illegal narcotics), fuel, and much more. Humans also benefit from biodiversity from what E.O.
Wilson calls "biophillia," which is the natural affiliation humans have for natural
environments.(E.O. Wilson)
Old growth forests play a dentrimental role in biodiversity preservation.
It's most important feature is biodiversity. Old growth forests provide us with many of the things
that we as humans take for granted, for example, breathable air pure water, and pest control through
birds, bats, and insects.
In the Eastern U.S., most of the old growth occurs in small isolated areas.
Scientist have come to the conclusion that even if these matured areas cover a substantial portion of
landscape, it will not provide long term diversity for many species that live in such a
community.(How much old growth..?)
Many environmentalists are increasingly concerned with this biodiversity

Biodiversity
a.Biodiversity– is the degree of variation of life. It is a measure of the variety of organisms present
in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation
(number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be highest near
the equator, which seems to be the result of the warm climate and high primary productivity.
Biodiversity is not distributed evenly on Earth. It is the richest in the tropics. Marine biodiversity
tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and
in the mid–latitudinal band in all oceans. There are latitudinal gradients in species diversity.

species diversity– is the number of different species that are represented in a given community (a
dataset). The effective number of species refers to the number of equally abundant species needed
to obtain the same mean proportional species abundance as that observed in the dataset of interest
(where all species may not be equally abundant). Species diversity consists of two components:
species richness and species evenness. Species richness is a simple count of species, whereas
species evenness quantifies how equal the abundances of the species are. g. species richness–is the
number of different species represented in an ecological community, landscape or region. Species

Effects of Loss of Biological Diversity
As the loss of biological diversity or biodiversity continues to increase at unprecedented rates, it
leaves a long–lasting effect on the environment of the planet Earth. Such effects are so threatening
that they can claim human lives in the near future.
Humans are clearing forests (deforestation) to occupy more land to urbanise more areas. Thus, as
humans continue to exploit the habitat of animals and plants for their own selfish needs, they harm
the entire environment of the earth. The deforestation has resulted in a variety of animals, which
dwell in that area, to leave the habitat. This is quite alarming as it could result in the loss of those
species diversity in the future.
The precious natural resources of the green earth are excessively exploited by humans. This includes
overharvesting animals to the extent that these species become extinct. It also includes
overconsumption of natural resources such as timber and fossil fuel which take years to regenerate.
This is a direct threat to biodiversity.
Humans pollute the environment in every way they can. They pollute the air with harmful pollutants
such as carbon monoxide, sulphur dioxide, chlorofluorocarbon (CFC) and nitrogen oxides produced
by industry and motor vehicles. These greenhouse gases are, in turn, destroying the ozone layer. The
ozone layer reflects the harmful ultraviolet rays of the sun. As this layer is being affected now,
humans are becoming more prone to

The Importance Of Biodiversity
Biodiversity loss is becoming an unpleasant pattern in today's world. Additionally, there are three
levels of biodiversity; species diversity, ecosystem diversity, and genetic diversity. Firstly, species
diversity is categorized as the volume of all living things. Secondly, ecosystem diversity is the
region/habitat in which the species thrive. Lastly, genetic diversity is the variety of genes in a
species, which allow the species to adapt and evolve to better suit their environment. Currently, the
world is witnessing a profound loss of biodiversity. According to The National Wildlife Federation,
the greatest species diversity is found among the invertebrates, including insects, crustaceans,
sponges, and scorpions. In addition, The National Wildlife Federation conclude that "scientists know
the least about the diversity of microscopic organisms such as bacteria and protozoa" (TNWF).
Although, Microorganisms may be tiny, but they are vital, forming the base of the food chain
ecosystems. The Millennium Ecosystem Assessment estimated that "8700 did per year or
approximately 24 species per day" (Fred Pierce). Ever since Cuvier discovery of extinction became a
concept in France, biodiversity rates have been on a steady decline (Kolbert 2015). The current
declining biodiversity rates are comparable to mass extinction events in the past. This is significant
because many animals depend on each other to maintain their lifestyle or play a vital role for the
environment. These species

Essay about The Importance of Biodiversity
What exactly is Biodiversity? Biodiversity is generally defined as "the existence of many different
kinds of plants and animals in an environment." (Merriam Webster Dictionary, n.d.) However, there
is no single definition for biodiversity. One definition for biological diversity is "a diversity among
and within plant and animal species in an environment" (Biological Diversity, n.d.). Biodiversity can
also be defined as "the number and variety of organisms found within a specified geographic region"
(Biological Diversity, n.d.). Another definition is "the variability among living organisms on the
earth, including the variability within and between species and within and between ecosystems"
(Biological Diversity, n.d.). There are at least...show more content...
At the opposite end of the spectrum, characteristics of genetically healthy populations include many
beings that are completely unrelated to each other.
Ecological diversity is the variation of habitat styles that are offered in a given area. These habitats
can have very dissimilar physical characteristics. Some examples of this are temperature and soil
type, as well as different entities occupying them. After the habitat with all its organisms and their
multifaceted exchanges are careful measured together, it is characterized as an ecosystem. Ecosystem
diversity is normally referred to as the level that is deliberated in relation to biodiversity.
Many different people for a variety of reasons have argued the value of biodiversity, but they all
point to a unified ideal of conservation. Humans would need to ensure that our natural resources are
available for all of our future generations. Several assemblies and establishments in our modern
society also are aware of the intrinsic value of biodiversity in all of its forms. Some examples of this
include waste managers, pharmacists, the food industry, the pet industry, hobbyists, hunters and
anglers, scientists and, finally, conservationists.
Biodiversity also means there are other options out there, and we have to find them. The options
range from medicine to technology that are inspired by animals and plants. The nature in the world
is an immense fountain of helpful information that might,

Based upon the same experiments and samples taken, it was concluded that the atmospheric nitrogen
pollution was caused by the burning of fossil fuels and rigorous agriculture (Ananthaswamy, 2004).
According to the 2004 release of the Threatened and Endangered Species System (TESS)
information, there are 599 endangered plants and 147 threatened plants in the US alone (TESS,
2004). These listings rely on a very stern legal system. Whether they can be labeled "rare",
"threatened," or "endangered", it is determined by the measure of endangerment the species sustain.
An "endangered" type is one that is in jeopardy of extinction throughout all or a major fraction of its
range. A "threatened" species is one that is likely to become in danger of extinction in the future
(UFWS, 2004).

Persuasive Essay On Biodiversity Conservation
Biodiversity Conservation in Australia
Biodiversity exists in every type of environment. Our existence, as humans, depends greatly on these
environments, whether it be for food, materials, or energy. Thus, the conservation of this biodiversity
is crucial in sustaining life on Earth. Currently in Australia, the risk of extinction is very real for
thousands of species. This is not only detrimental to the actual threatened species, but also for all of
the other species in the ecosystem that depend on it. Australia's biodiversity is constantly being
threatened by habitat loss, unsustainable practices, overuse of resources, and climate change.
Unfortunately, once biodiversity has been lost, it can never fully be restored, thus, we must act
quickly and efficiently to ensure that the least amount of permanent loss occurs.
According to Australia's 2010–2030 Biodiversity Conservation Strategy, there are three important
steps that must be taken above all else to conserve biodiversity. Firstly, all Australian's must be
engaged and motivated to take action. Secondly, everyone must work to aid in "building ecosystem
resilience." Lastly, once the first two steps have been taken, we must work toward attaining tangible
results (Australian Government Department of Environment and Energy).
Currently, the main cause of biodiversity loss in Australia is very much due to human intervention in
nature–this leading cause being habitat destruction. Thus, it is no surprise that the demolishing of the
rainforest is a major problem and threat to Australian biodiversity. As of now, with the massive
amount of deforestation occurring daily around the globe, Australia is the only western country to
still have large patches of rainforest. Thankfully, today's world has seen a surge in activism. Thus, it
is no surprise that there are many movements and campaigns by the Australian people to protect their
environment.
Unfortunately, however, activism is not enough to fully protect biodiversity and prevent further loss.
Even with all of the good that comes with these movements, there are a lot of problems with
Australia's current state of conservation. Australia has dug itself into a fairly deep hole; continuing
unsustainable practices in the

Reflection Essay On Biodiversity
So many interesting things there are to see stepping out my front door peering into my own front
yard. An incredibly biodiverse world that I have never paid much attention to until today. As I
walked around my front yard I would like to share with you the things I witnessed in the
following areas; my surroundings, the abiotic factors, the population, the community, the
interactions I saw, and my overall observation of God's goodness. As we look at the world around
us we are looking at biodiversity all the time, but most of us are not thinking about our
surroundings in these terms. Biodiversity according to David Krogh in his book Biology, A
Guide to the Natural World says that it means "a diversity of species in a given area,"(p.672). I
believe that having biodiversity is valuable because the more members you have in a community
the more resources you have at your disposal. This is important because it builds strength within a
community or as David Krogh said "more diverse communities tend to be more stable
communities," (p.673). In my front yard this morning I saw birds, rabbits, a few maple trees, leaves
on the ground with the dead grass poking through, some dying petunias, some dog scat. I
performed my observation at 8:02am and according to the weather app on my phone the
temperature was 46 degrees Fahrenheit with 55% humidity and the wind was 6mph. There were a
few clouds visible in the sky and the sun was up and it was a beautiful crisp fall morning.
There were two communities that I paid attention to the maple tree and the petunia plant. The maple
tree has nearly lost all of its leaves which were all orange and had lost their nutrients so that the
tree could live through the upcoming cold winter. As I looked at the petunia I noticed that though it
was clearly dying as well there was evidence of phototropism "curvature of shoots in response to
light,"(Krogh, p.452). This was a fairly large potted petunia plant and there were areas that seemed
to be fighting for light and food.
There were two populations I paid attention to the most and that was the birds that I watched fly
from tree to tree within my cul–de–sac and the rabbits as they chased each other around in my front
lawn, into the

Biodiversity Loss And Loss Of Species Essay
Biodiversity Loss
The environmental issue that I chose to research is 'Biodiversity Loss'. Biodiversity loss is the loss
of species on our planet. For example, this is animals and plants that have done extinct. This has
impacted every corner of the globe, since the dinosaurs we have lost thousands of animals and other
forms of life to extinction. According to Endangered Earth "there are now 41,415 species on the
IUCN Red List, and 16,306 of them are endangered species threatened with extinction,"
(Endangered Earth 2016). It is estimated that we only know about 15% of all the species that call
Earth home, at this rate we will lose thousands of species before scientist can even identify them
(Watson 2011). There are several reasons the humans are at fault for the extinction rate, to name a
few; hunting, loss of habitats, pollution, climate change, and so many others. One of the main issues
that is causing a loss in biodiversity is the loss of habitats. The majority of habitats that are destroyed
for more land or for their resources, which leads to having more land. When the land runs out of their
natural resources houses and other 'buildings' are built up in the place of the natural habitat. Once
the buildings are built, humans move into the area bringing diseases and species not native to the
area. This can simultaneously knock out hundreds of species that no longer have homes or are
unable to adapt to the new environment (Biodiversity Information 2016). One of the more

Biodiversity And Its Effects On The Environment
The sky is dyed red by the flames engulfing the forest. As water floods the land, what little is left is
quickly washed away. Those that would normally resist such disasters are gone. There are much
fewer species in our world than there was a long time ago because the world's biodiversity is in a
deplorable state. As more and more companies access and exploit natural resources at a rate which
the land cannot compensate, more and more organisms are disappearing from the planet. Although
some may believe that the companies actions have no effect on the environment, it cannot be denied
that many species are endangered or already extinct because of their actions; companies indirectly
and directly affect the biodiversity in the world. Biodiversity is the number of species of plants,
animals, microorganism, and ecosystems in a given region. As all species are somehow related and
codependent on one another, biodiversity plays an important role in the survival of many species.
Each organism, no matter how small has an important part in natural sustainability, ecosystems, and
species variety. Animals which live in the waters help to preserve water reservoirs and lakes, while
trees help prevent soil erosion and recycles nutrient. Many organisms help break down the pollution
that humans have spread. In the case of any natural disasters, they are able to compensate and
quickly help the environment recover. When their natural habitats are removed though, they are
forced into extinction

These countless species of plants, animals, and microbes affect our daily life in more ways than we
know. Species diversity is truly a magnificent process since all species are connected one way or
another continuing the cycle of life. Providing us with energy converted from sunlight and much
more.There are over 1.8 million different species sustaining life on
Earth, from which 1 million are insects! The main spot for species diversity is in tropical
rainforests, although tropical rainforests only comprise 7% of all land on Earth, they are home to
50% of all species on Earth! In some locations hundreds of species thrive while in others just a few
have evolved this is called species richness. Species diversity is the result of long–lasting
evolutionary changes which affect our planet's daily life, which is why species diversity is a vital
part to biodiversity. Each species has adapted to its own ecosystem or niche which is characterized
by features such as temperature, light availability, food, and water. Allowing species to reproduce
and thus maintain the population. Not only do species maintain population growth, but their
everyday interactions within their environment also has a vital impact on environmental health.

The Study of Biodiversity
Biodiversity – the amount of living things; animals, microorganisms and plants. It also includes the
genetic information these living things contain, and the ecosystems and biomes they form.
3 ways biodiversity can be studied:
–GENETIC DIVERSITY: The amount of different genetic characteristics of the species in their
genetic make up.
–SPEICIES DIVERSITY: the amount of species in a particular area in the world.
–ECOSYSTEM DIVERSITY: the amount of ecosystems in a given region or biome.
–Places of biodiversity include coral, rainforests, sea grass beds, and mangroves.
Australian soils
–Old and fragile soils. Water requirements of native plants are adapted to this.
–Australia is slowly shifting northwards. The climate will gradually change.
–Bushfires. Species can affect scale and range of the bushfires.
–Lowest rainfall of the 5 inhabited continents.
–Few rivers and lakes.
Australian biodiversity
–600,000 – 700,000 species.
–Endemic species; 83% of mammals, 45% of birds, 89% of reptiles and 93% frogs.
–About a minimum of 60–70 species have become extinct, since European settlement.
Hotspot(s)
–A region where there is at least 1500 of 800,000 or 0.5% of plant species (70% vegetation).
–Hotspots have high diversity, are not found outside the area, a loss of endemic species and are also
likely to be lost.

Biodiversity And Its Effects On Biodiversity
Abstract. Biodiversity is a variety of life and it is important to maintain biodiversity because it
provides everyone's needs for food source, water source and shelter. Currently, Georgia Gwinnett
College expanding with construction around the area, will this cause a disturbance where the
campus will not be able to have biodiversity or having some disturbance can increase it? The
research measured biodiversity in 5 different places around campus, these locations varying levels of
disturbance and resources. After analysis, it was determined that sites further away from the stream
at the downstream location had less biodiversity, and that the GGC site location had more
biodiversity than both of the stream locations, which may be due to more diverse habitats with the
location, or sharing more transition areas with areas of higher disturbance.
Introduction. Biodiversity is a variety of life on Earth at all levels from genes to ecosystems and
the ecological and evolutionary process that is able to keep biodiversity in balance (Willington,
2005). Biodiversity is important because it satisfy's everyone including animals, organisms and
humans basic needs such as food and water source and as well shelter(Wood, 1997). The overall
goal in biodiversity conservation is to create a foundation in developing ways to protect and use
biological resources in a way where it does not destroy important habitats in an ecosystem
(Nangendo, 2002). In ecology it has been taught that everything from

AGENDA 21 and AN OVERVIEW ON THE CONVENTION ON
BIOLOGICAL DIVERSITY
On December 22, 1989, the United Nations General Assembly called for a global meeting that would
devise strategies to stop and reverse the effects of environmental degradation. Agenda 21, adopted by
the United Nations Conference on Environment and Development on June 14, 1992, is the
international community's response to that request.
Agenda 21 is a "comprehensive program of action to be implemented from now and into the
twenty–first century by governments, development agencies, United Nations organizations, and
independent–sector groups in every area where human (economic) activity affects the environment"
(Department of Public Information United Nations 1). This program hoped to form a global
partnership where countries would strive to better manage and protect the ecosystem and bring a
more prosperous future for all of us.
Chapter 15 in Agenda 21 discusses the conservation of biological diversity. The objectives and
activities in this chapter are intended to improve the conservation of biological diversity and the

The Importance of Biodiversity
'Define Biodiversity and using examples, explain why it is important'
Biodiversity is the variety of life on earth. A fuller definition is given in the Convention on
Biological Diversity (CBD) from the 1992 Earth summit: 'Biodiversity is the variability among
living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the
ecological complexes of which they are part ; this includes diversity within species, between species
and of ecosystems' (Hambler, C., 2004, 11).
Within planet earth today Biodiversity forms the foundation for the vast array of ecosystem services
that critically contribute to human well being. It is as important in human managed ecosystems as
well as natural ecosystems (Hambler, C.,...show more content...
Endangered species of plants or animals may have properties yet to be discovered that could provide
important medicines (Hambler, C., 2004, 29). In addition to such direct benefits, the world's diverse
living creatures working in concert provide important ecological functions such as air and water
purification, climate regulation, erosion control, and providing oxygen in the atmosphere that
humans need to breathe (Hambler, C., 2004, 29).
Some ecologists also stress the aesthetic value of a natural world rich with an abundance of varied
and often beautiful life–forms. Many common human behaviours exhibit the importance of being
able to enjoy Biodiversity in many different ways. It may be that survival is possible but life
without this biodiversity being available may prove boring and unfulfilling (Primack, R.B, 2002,24).
In addition, the interactions taking place between world economics and biodiversity also has to be
taken into consideration. The arguments for the conservation of biodiversity with regards to
economics are divided quite broadly into 'direct use value' and 'indirect use value'. direct use value
is involved with microbial products such as animals and plants whereas indirect use is involved
with the ecosystem services that are provided by a group of species and habitats, these include the
likes of flood
