what are the main environmental problems facing the world today?

Normally you can get alot of information from current news issues like global warming or something else controversial.\n\nI have done one on global warming and other ones for example are genetic engineering etc. \n\nMake sure you choose something you are not twosided about.\n\nGood luck.

talk about global warming\nits a huge topic that will be more than enough to fill up 10 pgs\ntheres a lot to be researched too, so prepare for lots of work\nstuff like causes, preventions, consequences, proof\nresearch into Kyoto Accord, greenhouse gases, ocean currents, recent appearances of hurricanes (hurricanes build on warm air, and the temperature has been rising in the past few decades), car emissions, melting ice caps, change in migration of animals, stuff like that

It is Global Warming.  Geologically speaking we are still coming out of the last ice age.  We are on in a natural cycle which has been accerated by pollution.

right now  we have a trouble with our climate  is 3 big problems  from the last 5 years  we (humans )1.- in the whole world  destroy  forest and nature this contributes to the world warming  a lot\n2.- the sun activity is on a rise (so explode more continuously and flares are more bigger and hot) the sun activity  going down and up each 20/30 years  you can check it out for more information in wwww.nasa.gov or www.spaceweather.com\n3.- for many years the spray cans  , fuel in cars,  energy production with atomic energy, and fridge gas and many other substances made  by the man destroy the ozone layer and big holes in the pole  contributes to the warming to so in the next years  we got big tornadoes , very hot temperatures in spring and summer  the ice in the poles are melting now  and the seas going up soon with more water , next years many big problems with nature is coming , like hurricanes more bigger and Strong's , winters more cold with more snow and many other things\nand even the earth core get transformations we can help to restore some  if we plantting more trees if we use less oil, gasoline, and spray paint or other applications that come canned

Pollution and DDT can cause poor environments.  All the oil and logging industries causes detriment to fishing of salmon for eagles.  As civilization expands their habitat shrinks.

The world's population is following a very standard growth curve, which every population of animal follows.  It begins with a lag phase, then exponential growth, and then, as the species begins to reach equilibrium with what their environment can support, begins to level off.  We are just starting to level off - world population growth is slowing.  It is projected that the world will top out at 9-11 billion people.  This will not be an overcrowded situation - humans currently occupy only a tiny fraction of the planet.  Doubling that will not be a serious problem.\n\nThat being said, obviously there are limits to how many of us earth can sustain.  The biggest problem right now is that the birth rate is way too high in places that cannot support their population.  This problem will correct itself - it has to.

Carbon dioxide and other wastes. WHOA the second answerer is definitely going to win the voting.

Without a doubt, the most apparent threats to life on earth are all going to be man-made (Weapons of Mass Destruction, Pollution/Global Warming, etc.)

The most noticable would be CAR FUMES! Look there are as many cars as pets in the USA, I swear some of them just let too much pollution! You don't need a detail answer, all you need is imagination, just look at all the cars, factories, machines, trucks and every single one of those! They affect the climate dramatically, without even mentioning the military and nuclear weapons being produced there! \n\nUSA is in deep growing danger!!!

"Are we destroying the earth with technology or is the earth doing business as usual"\nI suggest you track the changes scientists have found in the entire history of the earth, warming, freezing, wet and even effects of smoke from Krakatoa. Then compare what is happening now with pollution and the depletion of the ozone layer and ask the readers to make their own conclusion.

In addition to rainforests--coral reefs. Over-fishing, pollution, and warming are negatively impacting the reefs in many parts of the world.

Environmental science is the study of the interactions among the physical, chemical and biological components of the environment; with a focus on pollution and degradation of the environment related due to human activities; and the impact on biodiversity and sustainability from local and global development. It is inherently an interdisciplinary field that draws upon not only its core scientific areas, but also applies knowledge from other non-scientific studies such as economics, law and social sciences. Physics is used to understand the flux of material and energy interaction and construct mathematical models of environmental phenomena. Chemistry is applied to understand the molecular interactions in natural systems. Biology is fundamental to describing the effects within the plant and animal kingdoms.

The earth when young was a nice place to live,\nTill man came along, and made the world give,\nNow the land is being polluted, And the air too,\nLets learn to recycle, and keep the earth new.

I  am very concerned about global Warming, The east coast could be underwater and the northpole could be gone in as little as 50 years. Today's choices could have a dramatic effect on the future. yet NOTHING is being done :(.

Global warming is definately a huge issue.  I don't think any countries are enacting on this issue currently

Not all advances in technology cause pollution. Man needs to put his mind to the types of science that work in harmony with nature.
