How has the world been affected as a result of these specific man-made changes?

Question

Nuclear power plants, Oil wells, and The Aswan Dam

Answer 1

You could write a book on this, the effects are complex and not even understood. There is no doubt that they have benefited humans, and even saved lives. In nature, there are always winners and losers.

Answer 2

This question is too broad and non specific to answer difinitively.

Nuclear power plants create several waste products that are very hazardous and the big problem is how to deal with those waste products and every politician and psuedo scientist thinks he has the answer but the main problem for nuclear power is what to do with the waste products responsibly.

Oil wells involve extracting oil from the ground and there is inevitably going to be degredation or damage to the surrounding environments which always includes harmful effects on the nearby ecosystems. Another major problem with oil drilling is the problem with oil spills polluting ecosystems, every major and non major waterway that supports the transportation of extracted oil has had oil spills of varying degrees of severity.

The problems created by hydroelectric power also include the increase or decrease of water available to natural ecosystems which can cause a major imbalance and cause some species of plants and animals to become extinct or threatened. When one area benefits from the daming of water another will suffer, consider the implications that removing most of the water from an area that previously had abundant water and the other area that now has a permanently flooded area. Maybe you were once able to canoe down a river that is now dried up because it has been dammed or you can no longer irrigate the land because there is no longer enough water available. Hydroelectric dams always cause water rights/use issues.

Answer 3

Wow this deserves a star.


Well, first of all it has affected the animals and the environment. Any change, no matter how mild or small, minuscule it may seem, it is ALL important. What you need to know is that a person can make a difference. Person after person adds up to people. People in its self can mean a lot. Maybe 10, maybe 50, maybe 5,000. What this means is that every change adds up to something much bigger. Wether it be: pollution, destruction of forests, animals, and of course us.

We use these things to make money. They benefit us in so many more ways too. They can make electricity, they help us keep our cars running. There is really no good without bad, and as far away as it seems: it is inevitable. Like global warming. These things all make the problem. But money is a very huge issue, not to metnion the products or the benefits of these things. Let's say the world ran out of petroleum all of a sudden? It would be extremely drastic and costly. All of a sudden, cars would be useless and not worth anything (besides the price the metal has). We would loose our biggest form of transportation. Think about it: it would truly be chaotic.

So what I'm saying is: despite the fact that it has bad things, it fuels what we have made. It is our fault. We have become so Dependant on certain things that our civilization would be doomed without it.

Answer 4

Level one answer: Electrical power is provided by all three. This increases the productivity of end user.
Level two: Nuke plants produce by-products which are both useful and waste. Ultimately these have to be disposed of. Oil wells do not have much of an effect once it becomes to expensive to pump. The dam had local effects in that people had to be relocated.

Answer 5

Some left wing "Tree Hugger's" would say a lot, so much so that you couldn't turn it around. Others say that for as long as we've been keeping records, compared to the age of the earth, that there is no way that anybody could accurately measure a change that could be definitely be attributed to the activity's of the human race. Any changes currently being monitored now could just as easily, and more likely, be the cause of natural occurrences. Just like the magnetic field flipping poles from time to time. If it happened tomorrow the lefty's would know doubt blame it on the industrial, military complex.

Answer 6

Tell you the truth I will...
The world has been brought to the brink of extinction.
