need for preserving the environment?

Answer 1

Environment is the sum of all external conditions affecting the life, development and survival of an organism.
The burning issue in today’s context is the protection of the environment for the survival of all living organisms to maintain the ecological balance.
Ecology is the relationship of living things to one another and their environment, or the study of such relationships.
Ecological/Environmental Sustainability is maintenance of ecosystem components and functions for future generations.
Ecological Integrity: A living system exhibits integrity if, when subjected to disturbance, it sustains and organizes self-correcting ability to recover toward a biomass end-state that is normal for that system. End-states other than the pristine or naturally whole may be accepted as normal and good.Ecological Integrity ensures ecological balance.
Ecosystem: The interacting system of a biological community and its non-living environmental surroundings.
Ecosystem Structure deals with the attributes related to the instantaneous physical state of an ecosystem; examples include species population density, species richness or evenness, and standing crop biomass.
The factors affecting the environment today are
1. Effluents
2. Emergency and Hazardous Chemical Inventory
3. Emergency (Chemicals)
4. Agricultural Pollution
5. Agricultural Waste
6. Air Pollutant
7. Air Toxics
8. Emission
9. Endangered Species
10. Energy Management System
11. Energy Recovery
12. Environmental/Ecological Risk
13. Environmental Tobacco Smoke
14. Passive Smoking/Secondhand Smoke.
15. Use of Ethylene Dibromide (EDB)
16. Extremely Hazardous Substances

Some of the measures which could safeguard the environment are

1. Ecological/Environmental Sustainability
2. Effluent Limitation
3. Use of Electrostatic Precipitator (ESP)
4. enforcing Emission Standard
5. Engineered Controls:
6. Environmental Audit
7. Use of Ethanol as an an alternative automotive fuel
8. Prevent Acid Deposition and acid rain
9. Avoid Adulterants
10. Avoid Adulterated chemicals:
11. Aerobic Treatment: Process by which microbes decompose complex organic compounds in the presence of oxygen and use the liberated energy for reproduction and growth. (Such processes include extended aeration, trickling filtration, and rotating biological contactors.)

Answer 2

In short, we are measurably losing life on a daily, even hourly, basis. Tropical forests continue to be a prime example because their destruction is causing a species extinction rate rivaling anything the earth has experienced in 65 million years. Two points need to be considered. First, some scientists believe giant meteorites colliding with the earth caused the previous mass extinctions. Even if human civilization had been in place, we could not have prevented that destruction. Second, the great elimination of species that occurred at the end of the last two geologic eras resulted primarily in the loss of animal species. Plants, the basis of food chains, were not as severely affected. Today, we are rapidly losing both plant and animal species in the tropics. But this time, we are the meteors. We can control the path we take.

Check into finding if your area has recycling stations for paper, glass, metal and plastic. Locate these stations and make efforts to recycle when feasible.

Reduce car emissions by using your car less: Speak to co-workers and organize a carpool club. Use public transportation or bicycling also.

Environment preservation can also help save home utility costs. Look into buying those flourscent interior energy saving light bulbs. If the room isn't being used, turn OFF th e lights.

Check windows and doors for air leakages, calk sealing them if possible w/out interrupting window opening/closing.

Safety is important when pink fiberglass insulating your hot water heater, which should limit its electric or gas use.

Set your PC to "sleep mode" if left on for long periods of time and unplug your TV sets before you retire off to sleep.

And follow disposal instructions for car oil (if you change your car's oil) and batteries--very important in enviroment conservation.

Answer 4

Yes we need to preserve environment. For that we ourselves you , me and everyone should start from small things and eventually environment can reach the normal state of working expected out of it.
