Because we are human. It is in our nature to destroy as we create. Accept it. There is nothing you can do.

through trees and the process of photosyntesis..\n\nglobal warming occurs because of the excess of certain gases, CO2 and others, in the atmosphere. photosyntesis can help recycle those gases by turning them into oxygen. By cutting down trees there's less ways to get rid of those gases and so they keep accumulating in the atmosphere causing an increase in global warming.\n\nhope that helps

In the context of your question,\n\nA resource is a source of material or energy that may be consumed, changed, or dispersed to the point it is no longer easily usable. Examples would be copper ore, oxygen in the atmosphere, helium gas taken from oil wells, water, sand, or even soil. Anything we do consumes or utilizes some sort of resource. Breathing uses oxygen from the air. Copper is used for wiring and piping. Helium is used for scientific research and birthday balloons. Sand is used to make concrete. Water is used for drinking, irrigation, and generating hydroelectric power. Soil is used for growing crops.  None of these are exhaustive lists, just examples. \n\nOil: Oil is a mixture of organic compounds extracted from the earth by drilling. It is created from organic materials deposited in sedimentary rock that are altered by heat, pressure, and biotic processes to create it. \nOil is used to make gasoline, diesel, airplane fuel, plastic, shampoo, rubber, antihistamines, and many other products. \n\nNatural gas: It is an organic gas that is also extracted from the earth by drilling. It is generated by a similar process to that for oil generation. It is used to heat homes, make fertilizer, and some plastics. \n\nWater: Water is found in many forms, but mostly as either fresh or saltwater. Fresh water is used for drinking, irrigation, etc. Saltwater is not as useful directly to man, but is an essential part of our environment as the oceans both support food supplies and have a large effect on the climate. \n\nWood: Wood comes from living organisms- trees. Wood can be used for building many things, including houses. It is used for fuel and is the primary source of fuel in some parts of the world.

The sun is the source of energy. Plants are next. Then herbivores or plant eaters. Then comes the carnivores that catch and eat the herbivores. Finally are the decomposers

u can write that government should ban hunting and many maore things...the future of the upcoming generations is in thier hand ....because NO WILD ANIMALS MEANS MORE HERNBIVORES AND MORE HERBIVORES MEAN LESS PLANTS..LES PLANTS MEAN LESS AIR AND WATER....AND IN THE END NO HUMAN......THIS IS TRUE....PLS ACCEPT MY ANSWER BEST$$$

It would post probably be sunlight.......some plant organisms may survive without water for long periods of time, such as ones in the desert....... but sunlight is required for green plants to make food  which unlike for humans......... food is the bigger priority than water

I do agree,they claim el nino is responsible,some claim global warming. The semi cold weather with wet,cloudy days is depressing not to mention it brings on aches and pains......Illness The cold snowy days seem to bring excitement, to cold for the germs. My personal theory is the whole Earth has shifted orbit just enough to mess the weather up. Scientifically I would go with global warming or the green house effect. We have used and released so much freon or R-12 into the atmosphere, plus other pollutants its really damaged are enviorment all for comfort. Maybe we should go back to horse and buggies..lol

listen to t. h. white (sword in the stone author). we will in the end use up all our resources and the organisms that need them will die. it will break off part of the food chain and no other organisms will be able to live. the part of that is what happened to the dinosaurs (likely) and it will probably happen to humans considering how destructive we are.

If you have the book and the chapter reference, look these up:\n- ecological niche\n- intraspecific competition\n- resource partitioning\n- competitive exclusion\n\nEverything will be clearer then.

Wow, interesting article.  Possibly one of the best-written and moth truthful ones I have seen.  It's amazing how well people have hushed up the most recent climatological results which indicate a plateau in global temperatures.\n\nAs they noted at the end of the article, I think it's time we gave up on this misguided effort to "reduce man-made CO2", and start worrying about real issues like shortages of drinking water and environmental pollution.\n\nClimate fluctuations are part of the earth cycle- and we honestly don't understand enough about they systems and their interactions to have any idea how we could possibly effect it.  But the science is in:  this happens ALL the time in earth history, and it's pretty arrogant of us to think that this time it's our fault!

I have heard it as "for every action, there is an equal and opposite reaction" As for people and environment.  Someone cuts down a forest- what happens? Soil biodiversity changes, animal species in that area change, CO2 consumption in that area decreases.\n   People put more black top up- absorbs and reflects heat warming the earth's surface more. There are a ton of examples, I am not sure what you are looking for specifically.

let's see, cutting down canada's ancient boreal forests by kimberly-clark so they can make KLEENEX, disgraceful.\ncutting down forests to expand factory farming only so that the animals can be slaughtered. horrifying.  by far it is human selfishness and lack of education that is destroying our world.

C for sure.\nMy but didn't this question get some folks hot and bothered. \nMay I point out that yes the plants are using the co2. Meanwhile, we silly homo saps are, while busily pumping hydrocarbons and co2 into the atmosphere, blithely burning down, chopping down and otherwise doing away with rain forests in South America. We are also draining swamps in Florida and filling them in to build houses, hacking down forests in Africa and other countries for the same reason.  All that means less of those nice green plants to absorb all that CO2.\nNow it is possible that we are just in a between glaciation warm spell. But even if we are, there is still the possibility of pushing that warm up over the edge into something we might not be able to survive.

There have been a number of ecological problems cause when existing species are moved out of their natural habitat. The jackrabbits in Australia is one example.\n\nGenetically engineered species could have the same effect. If you accidentally introduce what is essentially a new species into an ecosystem, the results could be disastrous.\n\nNote: Genetic engineering efforts tend to be concentrated on domestic animals and plants.  You are unlikely to have to worry about dairy cattle escaping into the wilds.\n\nAnother problem is that bioengineered food may pose a problem for people with food allergies.  If, for example, peanut genes are spliced into some other food plant in an attempt to make it better, eating it could possibly affect people who are allergic to peanuts.  It could become hard to tell what foods would be safe for them to eat.

I have to believe that we are on a downward spiral. We are depleting the primeval rain forests which provide oxygen and burning fossil ie carbon fuels which produce carbon monoxide and carbon dioxide, in addition to excreting sulphur which produces sulphurous and sulphuric acid. The westernised/civilised world is reluctantly taking small steps, but the 3rd world is increasing at an alarming rate.\nGlobal warming is a fact, and the result of this within this century will be frightening both in terms of sea-level rises and also hurricanes/typhoons/cyclones. Let us see what damage is caused in the Gulf of Mexico THIS year....

The biggest problem is probably global warming. Global warming disrupts and alters the natural currents in our oceans. Cold water is more dense than warm water and rises. So if we mess up the currents, the living things within the water is disrupted.
