can sum1 give me information on how man causes imbalance in nature?detailed please?

Question

for my brother's holiday homework

Answer 1

Without getting too philosophical, you are actually asking a very difficult question. Man, after all, is part of nature. Even though we distinguish ourselves from other living beings on the planet by our level of intelligence and our ability to use tools and technology, we are just another form of parasite using the whole planet as our host. We are very thourough in that respect.

Secondly, in theory, systems in nature seek stasis, or balance where no change occurs. In reality, systems are dynamic, changing all the time. Humans have a large inpact on the dynamic nature of the planet.

Here's a few examples; Dams, roads, cities, agriculture, mining and forestry all impact the landscape around themselves.

Sometimes the impacts are temporary, ie; with proper mangement and stewardship, forests regrow. Sometimes the impacts are longer lasting; ie, poor forestry mangement results in ground erosion which may reduce soil cover that impacts regrowth which in turn leads to watersheds silting up, which in turn impacts fish populations, which in turn impacts organisms like bears and birds that rely on fish. You get the picture.

Almost all human activity impacts "nature" somehow, and that creates imbalance. Imbalance isn't always bad however. All things have a cost. No forestry business - no wood, no mining, no steel, no agriculture, not enough food.

Answer 2

although i just believe it is the world changing the climate here is my info:
Since the beggining of man having a gas powered cars, coal refining stations and many other gas powered machines, man has been giving off carbon dioxide, or CO2. the atmosphere is compose mostly of nitrogen and oxygen and has small amounts CO2. some scientists think that there is no increase in CO2 levels because of man. but since there is so much CO2 emmissions in the world, it is hard to ignore. As to global warming having to to with man, the CO2 that man gives off supposedly has been heating the world up, making storms fiercer, and more deadly. Some scientists believe that if we stay on the same track, the ice caps will eventually melt.

Well, for starters, we tear down trees and destroy forests to build houses, which are built on habitats or animals.

We put harmful pollutants in the air, soil, and water, killing and hurting many forms of life.

We know about these problems but we are too selfish to stop.

And thats just for starters.
