1. Biodiversity and Land Quality Essay
Biodiversity and Land Quality
Human society's progression through time has resulted in many environment–altering effects, particularly those brought about by industrialization and
rapid population growth. The combination of increased numbers of humans and improved technology has created the need for better management of
resources and transportation across the globe. This need has produced great leaps in infrastructure, such as roads and dams. However, the introduction of
this infrastructure into the natural world has adversely affected the environment. Biodiversity is often drastically altered, resulting in changes in
breeding and predation patterns which, in turn, lead to species extinction and degradation of soil and vegetation. The...show more content...
Land–use change has the greatest impact on soil biota, which dictates types of vegetation and the kinds of animals which consume it. Important areas
of biodiversity, such as forests and wetlands, are claimed by encroaching dams and roads– in Asia, more than 5,000 square km of wetlands are lost each
year to industrial activities, primarily irrigation and dam construction (Myers 129). Dam construction also has an effect upon areas far away from the
physical dam itself. A study on the impacts of damming in North America found that sites remaining structurally intact after nearby dam construction
still lost an average of 0.5 to 1.0 % of its species each year for at least 50 years, due to the restriction of necessary flooding). Infrastructure
construction decreases the diversity of all soil taxa and makes conditions very unfavorable to biodiversity (Balmford et al. 13).
Roads and dams impact wildlife by altering animal behavior and species distribution. Plants and animals are affected by modifications to the chemical
environment, interference with the physical environment, and significant noise. Dams in particular emit large amounts of methane and reduce water
supplies to wildlife that is downstream

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

3. Essay On Endangered Plants
Biodiversity
Imagine this: you step outside and feel the barren, rough, red Earth beneath your feet. There's not a single plant in sight–no rustling of the leaves, no
mighty towering trees to block the severe winds, and the scorching heat of the sun searing upon your face because there's no shade. And when you take
a whiff of air, you feel nothing filling up the space inside your lungs, liberating your body's activities. What's wrong with this picture? It's not possible,
of course. Even though plants aren't the building blocks of life, they're pretty close and without them, most of life wouldn't exist–YOU wouldn't exist. In

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).
Ways for prevention of plant dissolution/ rewards
Here in DeKalb County, we have several different threatened plant species. They are: Bay–star Vine, Flatrock Onion, Granite Rock Stonecrop, Indian
Olive, Piedmont Barren Strawberry, and the Pool Sprite Snorkelwort. We have one endangered plant: it is the Black–spored Quillwort (UFWS, 2004).
There are over 542 discrete approved ecosystem recovery plans. Some plans cover more than one species while a few have different plans covering
various parts of their ranges (TESS, 2004). One organization is the Botanic Gardens Conservation International. It has just recently been added as a

The shade plants look unhealthy because it was grown quickly. Some nutrients look like their missing because it's more yellowish. If I found a
sample group pot of wildflowers I would feel like I'm living in a healthier ecosystem because all the wildflowers are greener with healthier stems.
Answer = All living things that are a part of the ecosystem are also part of web life and we can't be without biodiversity. "Maintaining a wide diversity
of species in each ecosystem is necessary to preserve the web of life that sustains all living things," (Brown, 2008). It's important because everything
on this earth is here for a reason and this role is very important. If we didn't have diversity all the species wouldn't be able to interact or depend on
each other and the ecosystem suffers.

"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...show more content...
In the video, during the drought, the side of the field with a more diverse environment held stern as the other wilted away.
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

8. 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

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,

`This question is a main concern for present and future generations. In its simplest terms, biological diversity is the variety of life and its processes, and
it includes the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur. In any

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 sustainable use of biological resources, as well as support the

"Biological diversity is of fundamental importance to the functioning of all natural and human–engineered ecosystems, and by extension to the
ecosystem services that nature provides free of charge to human society "(Lloyd, 2014). Biodiversity is very important to both plants, animals and
humans on Earth and if one species is destroyed it throw the balance off .
What is a species?
A species is certain kind of animal, plant, fungus or other organism. Which is a group of individual that are part of interbreed in nature, it is the
largest gene pool under a natural condition. It is when a pair of organisms produce and offspring in nature and both parents need to belong to same
species. This definition does not include many types of bacteria which are capable to asexual reproduction. Another difficult way of understanding
would be like for example a cat species are capable of hybridizing such as a lion and a tiger who mate and produce a liger as well as a cross between a
male jaguar and female lion which produce a jaglion. Species are formed through a process called speciation and this happens when lineage of single
splits into to two or more separate species, this is how new species are created.
What is the difference between a threatened species, an endangered species, and an extinct species?
Provide at least one example each of a threatened, endangered, and extinct species, and explain why these

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. Biodiversity generally tends...show more content...
As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but
usually encompass specific, limited spaces. f. 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 richness is
simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions.
