Ecology is the study of the interactions between organisms and their environment. Key topics in ecology include the components of ecosystems like producers, consumers, and decomposers; trophic structure and food webs; nutrient and energy cycling; and major ecosystem types such as forests, grasslands, aquatic systems, and deserts. Ecosystems can be classified based on their environment, study area, or level of human impact. Understanding ecology is important for appreciating humanity's role in modifying the environment.
The document defines environment and environmental science. It states that environment includes all physical and biological factors surrounding organisms and their interactions. Environmental science is a multidisciplinary field concerning conservation of nature and resources, pollution control, population issues, and more. The document also discusses ecosystems, including their components, functions, types of food chains and webs, ecological succession, and ecological pyramids.
Environment literally means surrounding and everything that affect an organism during its lifetime is collectively known as its environment. In another words “Environment is sum total of water, air and land interrelationships among themselves and also with the human being, other living organisms and property”. It includes all the physical and biological surrounding and their interactions.
Environmental studies provide an approach towards understanding the environment of our planet and the impact of human life upon the environment.
Thus environment is actually global in nature, it is a multidisciplinary subject including physics, geology, geography, history, economics, physiology, biotechnology, remote sensing, geophysics, soil science and hydrology etc. Scope of Environmental Science Environmental science is a multidisciplinary science whose basic aspects have a direct relevance to every section of the society.
Its main aspects are:
• Conservation of nature and natural resources.
• Conservation of biological diversity.
• Control of environmental pollution.
• Stabilization of human population and environment.
• Social issues in relation to development and environment.
• Development of non-polluting renewable energy system and providing new dimension to nation’s security. Importance of Environmental Science Environment belongs to all the living beings and thus is, important for all.
Each and every body of whatever occupation he or she may have, is affected by environmental issues like global warming, depletion of ozone layer, dwindling forest, energy resources, loss of global biodiversity etc.
Environment study deals with the analysis of the processes in water, air, land, soil and organisms which leads to pollute or degrade environment. It helps us for establishing standard,Environment and Ecology for safe, clean and healthy natural ecosystem.
It also deals with important issues like safe and clean drinking water, hygienic living conditions and clean and fresh air, fertility of land, healthy food and development. Sustainable environmental law, business administration, environmental protection, management and environmental engineering are immerging as new career opportunities for environment protection and managements.
Need for Public Awareness With the ever increasing development by modern man, large scale degradation of natural resources have been occurred, the public has to be educated about the fact that if we are degrading our environment we are actually harming ourselves.
To encourage meaningful public participation and environment, it is necessary to create awareness about environment pollution and related adverse effects.

All around the world, every country, city and nation have the same.docxgalerussel59292
All around the world, every country, city and nation have the same recurring problem of waste. The main problem with our way of taking care of the waste we create is that we do not use that same waste and recycle it. The reason for this is that people are not being taught about waste disposal correctly. There are many plastic and metals that we throw away that can be recycled but many places, which are responsible for the recycling, don’t take them because there isn’t enough workers to do so. Futhermore waste like apple cores, banana peels all can be recycled and used as fertilizers or a way to create energy known as methane gas, however not enough recycling places do so. The biggest problem, however is that we live in a wasteful time. The idea that we just throw away our things or used products without being responsible for it is not good. We need to be using more recyclable objects and each person is charged on how much they throw away, rather than a flat rate for everyone. With all this waste earth is dying. Animals are losing their homes turning them into landfills. Man and animals cannot live in a world where the waste is just being dumped away. Problems such as pollution, global warming and other will make it harder and harder for us to live. That problem is that people out there don’t care enough to do something about it as they don’t have the knowledge to what this can lead to. I believe more education about waste should be taught and what the damages of poulltion can do to our earth. We see this today with temperatures rising, causing animals not being able to live as these temperatures destroy their habitats. In Cities like los angeles the air is polluted to a point where you can literally see the smog and such over the city. Something has to be done before its too late.
We have the ability to do something about this. And change our enoviroment before its too late and doesn’t just end up being a waste. In years time if we don’t do something about this the problem will be bigger and bigger to the point where we can no longer live on this earth. If we keep "air" pollution up for another 1000 years, we will be sufficated by carbon monoxide. If we keep "water" pollution up, we will die of thirst. If we keep "land" pollution up, we will be buried by our own waste.

In this lesson you will comprehend how the consumption of everyday p.docxmigdalialyle
In this lesson you will comprehend how the consumption of everyday products affects the availability of renewable and nonrenewable natural resources for future generations and learn about environmental threats to our home.
Read the following information to help you define three different types of resources—renewable, nonrenewable, perpetual.
1. On earth, there are only limited amounts of fossil fuels, such as coal, oil and natural gas. There are also only limited amounts of minerals, such as iron, copper and bauxite. These resources either cannot be replaced by natural processes or require millions of years to replenish.
2. Some renewable and nonrenewable resources can be recycled or reused. This process decreases the rate at which the supplies of these resources are depleted. For example, aluminum cans can be recycled and turned into “new” cans or other aluminum products many times over. Recycling reduces the need to mine bauxite, the mineral used to manufacture aluminum.
3. Renewable natural resources include plants, animals and water when they are properly cared for. Minerals and fossil fuels such as coal and oil are examples of nonrenewable natural resources.
4. Trees, wildlife, water and many other natural resources are replaced by natural processes. Plants and animals can also be replenished by human activities. Water is continuously cycled and reused. Sunlight, wind, geothermal heat, tides and flowing water are perpetual resources.
Water is a resource that is typically considered renewable. However, over usage of water can cause us to use it faster than it is replenished.
The chart below approximates daily water consumption in the United States:
1. Thermoelectric Utilities 187 billion gallons/day
2. Irrigation 137 billion gallons/day
3. Public Water Supply 36 billion gallons/day
4. Industry 26 billion gallons/day
5. Rural and Livestock 8 billion gallons/day
Total 394 billion gallons/day
What are the threats to our environment?
Biodiversity
Biodiversity is all of the Earth's plants, animals, ecosystems and genes. It includes the tallest tree, the smallest insect, and the most delicate coral reef ecosystem. Biodiversity is what allows the Earth and all of its creatures to adapt and survive.
As humans, we are completely dependent on biodiversity for survival. Yet we are destroying large parts of our natural world. In places far and wide, humans are squeezing out other forms of life, sometimes causing the extinction of entire species.
We have the power to change our course. Each of us can act to protect our biodiversity and help create a sustainable future for life on Earth. Learn more about biodiversity and how

I believe more education about waste should be taught and what the damages of poulltion can do to our earth. We see this today with temperatures rising, causing animals not being able to live as these temperatures destroy their habitats. In Cities like los angeles the air is polluted to a point where you can literally see the smog and such over the city. Something has to be done before its too late.
We have the ability to do something about this. And change our enoviroment before its too late and doesn’t just end up being a waste. In years time if we don’t do something about this the problem will be bigger and bigger to the point where we can no longer live on this earth. If we keep "air" pollution up for another 1000 years, we will be sufficated by carbon monoxide. If we keep "water" pollution up, we will die of thirst. If we keep "land" pollution up, we will be buried by our own waste.

In this lesson you will comprehend how the consumption of everyday p.docxmigdalialyle
In this lesson you will comprehend how the consumption of everyday products affects the availability of renewable and nonrenewable natural resources for future generations and learn about environmental threats to our home.
Read the following information to help you define three different types of resources—renewable, nonrenewable, perpetual.
1. On earth, there are only limited amounts of fossil fuels, such as coal, oil and natural gas. There are also only limited amounts of minerals, such as iron, copper and bauxite. These resources either cannot be replaced by natural processes or require millions of years to replenish.
2. Some renewable and nonrenewable resources can be recycled or reused. This process decreases the rate at which the supplies of these resources are depleted. For example, aluminum cans can be recycled and turned into “new” cans or other aluminum products many times over. Recycling reduces the need to mine bauxite, the mineral used to manufacture aluminum.
3. Renewable natural resources include plants, animals and water when they are properly cared for. Minerals and fossil fuels such as coal and oil are examples of nonrenewable natural resources.
4. Trees, wildlife, water and many other natural resources are replaced by natural processes. Plants and animals can also be replenished by human activities. Water is continuously cycled and reused. Sunlight, wind, geothermal heat, tides and flowing water are perpetual resources.
Water is a resource that is typically considered renewable. However, over usage of water can cause us to use it faster than it is replenished.
The chart below approximates daily water consumption in the United States:
1. Thermoelectric Utilities 187 billion gallons/day
2. Irrigation 137 billion gallons/day
3. Public Water Supply 36 billion gallons/day
4. Industry 26 billion gallons/day
5. Rural and Livestock 8 billion gallons/day
Total 394 billion gallons/day
What are the threats to our environment?
Biodiversity
Biodiversity is all of the Earth's plants, animals, ecosystems and genes. It includes the tallest tree, the smallest insect, and the most delicate coral reef ecosystem. Biodiversity is what allows the Earth and all of its creatures to adapt and survive.
As humans, we are completely dependent on biodiversity for survival. Yet we are destroying large parts of our natural world. In places far and wide, humans are squeezing out other forms of life, sometimes causing the extinction of entire species.
We have the power to change our course. Each of us can act to protect our biodiversity and help create a sustainable future for life on Earth. Learn more about biodiversity and how

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
2. Chapter 1: Introduction to
Environmental Science
Objectives: At the end of the lesson, the student should
be able to:
1.define environmental science and ecology
2.state the history of Ecology; and
3.relate the ecological principles and laws
3. Lesson 1: Definition of Environmental
Science & Ecology
• Environmental Science gives an overview of how the biotic
and abiotic affects our environment. It also focuses on
interactions between the solid Earth, its water, its air and its
living organisms, and on dynamic, interdependent
relationships between these four components.
• Ecology is the branch of biology that deals with the relations
of organisms to one another and to their physical
surroundings.
• Ecology is the study of how living things interact with each
other and their environment. This includes living things
(biotic factors) and non-living things (abiotic factors).
4. Lesson 2: Historical Roots of Ecology
Ecology usually derived from teo Greek
word “Oikos” which means “HOUSEHOLD”
and “logos” meaning “TO STUDY”.
The term ecology was first defined by the
German biologist Earnst Haeckel in 1866.
5. Our Role in Ecology

9. Lesson 3: Ecological Laws & Principles
- Four Laws of Ecology
• 2.Second law of Ecology – Everything
must go somewhere.
Example situation:
Dry-cell battery mercury is purchased, used to the point of exhaustion and then
thrown away. But where does it really go? First, it is placed in a container of
rubbish, this is collected and taken into an incinerator. The mercury is heated; this
produces mercury vapor which is emitted by the incinerator stack and mercury
vapor is toxic and carried by the wind eventually brought to the earth in rain or
snow. And if any chance, mercury condenses and sinks to the bottom hence, it is
acted by the bacteria which converted it to methyl mercury. From this scenario,
what will be the fate of methyl mercury as it flows out to the bodies of water.
11. Lesson 3: Ecological Laws & Principles

compromising the environment
12. Lesson 3: Ecological Laws & Principles
- Four Laws of Ecology
4. Fourth law of ecology. There is no such
Thing as a Free Lunch
Example situation:
Deforestation activity of human shows lack of concern about to the
environment. This activity cannot be avoided nowadays but need to
mitigate it. The environmental crises can be delayed but may be
manifested as time goes by.
