Global warming, also known as the greenhouse effect, received international attention from scientists, environmentalists, and governments around the world. It is caused by gases trapping heat near the earth's surface, warming the planet and threatening the environment.
Many factors contribute to global warming, including overpopulation, industrialization, transportation, and other human activities that release greenhouse gases into the atmosphere. If temperatures rise significantly, some of the polar ice caps will melt, raising global sea levels and potentially flooding coastlines.
Uncontrolled global warming could cause a major catastrophe by displacing millions of people and ruining croplands with rising seas. It may also cause some low-lying island countries to
Biotechnology can be applied to waste management through microbial fuel cells (MFCs). MFCs use microorganisms to convert the chemical energy in organic compounds into electrical energy. They have two chambers, an anode where microbes in the wastewater oxidize organic matter and release electrons and protons, and a cathode where oxygen reacts with the electrons and protons to form water. This generates a current that can be used as energy. The document describes a student's experiment using an MFC with effluent water, which generated voltages of up to 120mV over 5 days. MFCs provide a way to both treat wastewater and produce renewable energy, though further improvements are still needed.
Applications of environmental biotechnology by Hameer KhanHumair Sindhi
The document discusses applications of environmental biotechnology. It defines environmental biotechnology as using biological systems to develop and regulate the environment in a sustainable way. It discusses six major applications: biomarkers to measure pollution exposure; biosensors to detect toxins; biofuels as renewable energy; bioremediation to clean pollution; biotransformation to convert toxins; and molecular ecology to study biodiversity. Overall, environmental biotechnology aims to keep the environment clean for future generations through sustainable use of organisms.
Biotechnology is an indigenous wave of innovation. This enhances the quality of the environment by protecting the natural resources. It plays key role for sustainable agriculture.
Biology - Chp 3 - The Biosphere - PowerPointMr. Walajtys
This document discusses key concepts in ecology including:
1) Ecology is the study of interactions among organisms and between organisms and their environment. The biosphere is made up of different levels of organization from individuals to the entire planet.
2) Energy flows through ecosystems in one direction from producers to consumers while matter cycles through ecosystems as it moves between organisms and the non-living environment through processes like the carbon, nitrogen, and phosphorus cycles.
3) Nutrients are required by all organisms and cycle through ecosystems, with their availability impacting ecosystem productivity. Certain nutrients can become limiting if scarce.

Biotechnology has many applications in agriculture including genetic engineering of crops. It can help increase crop yields and make crops more resistant to pests, diseases, and environmental stresses. However, there are also concerns about the health and ecological impacts of genetically modified crops. In Pakistan, biotechnology in agriculture is growing with research centers working on developing salt tolerant rice, insect resistant cotton, and virus resistant potatoes through genetic engineering. Bioinformatics also helps with genome analysis and databases to support agricultural biotechnology.
This document discusses the application of biotechnology in the food, pharmaceutical, and agriculture industries. It provides examples of how biotechnology is used in food processing, such as developing new emulsifiers and tests for food allergens. In pharmaceuticals, biotechnology has been used to develop vaccines, insulin, blood products, and gene therapies. In agriculture, biotechnology can be applied to increase pest resistance, disease resistance, nutritional quality, and environmental stress tolerance in crops. Genetically modified crops are also discussed.
This document discusses environmental biotechnology and its applications. Environmental biotechnology uses biological processes like bioremediation, biosensors, and bioindicators to solve environmental problems and reduce pollution. It deals with decontaminating the environment from various contaminants released by industry, and minimizing waste and pollution through techniques like bioremediation, which uses microorganisms to degrade contaminants into less toxic forms. The document also describes different types of biosensors and bioindicators that can be used for biotechnological applications like monitoring the environment.

ABC Don't Expect Pay Phones to Disappear--2001Anne Melfi
Analysts say payphones will not completely disappear despite their declining numbers and revenue challenges faced by payphone service providers. While only 2.2 million payphones remain in service, down from 2.6 million a few years ago, some analysts believe the decline could stabilize or even reverse as not all Americans own wireless phones and many homes and inner cities still lack traditional phone service. Payphone service providers are pulling some phones due to lower revenue from wireless substitution and free dial-around options, but some are staying in business while awaiting potential enforcement of laws requiring compensation for all phone calls, not just 911 calls.
ABC FDIC ... mortgage-backed securities, year 2000Anne Melfi
The FDIC is testing the market to see if selling two mortgage-backed securities as outright loans would yield a higher return. The loans are among the last remaining from the Resolution Trust Corporation, which was dismantled in 1996 after cleaning up the savings and loan crisis. If the direct loan sales are favorable, buyers could pursue acquiring 16 more loans. Selling loans directly could drive up the price compared to continuing to derive income from the securities.
