Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years. We have been using about 2 to 3 times more of our resources than we have available. These resources have been being used because of industrial booms. Be smart and use only what you need.

Acid rainis caused by air pollution, this rain contaminates rivers, lakes and other bodies of water. The acid rain could also take form in snow, mist, and even dry dust. The rain can be harful to plantlife, ruining soil and harming the outer layers of trees. The effect on animal life is big too. The animals sources of water may have been to acidic and could be harmful. Our pollution continues to affect nature more and more.

Even though the pipeline is under the ground some of the oil has risen to the top. This particular spill happened to be on tribal land when previously promised that they wouldnt put any piplelines in the area.
The idea of putting a new pipeline in Nebraska is protested against and may not be built because of reacurring spills. http://www.cnn.com/2017/11/16/us/keystone-pipeline-leak/index.html Currently we have a population of about 7 billion people, and this could be a problem. The carrying capacity could be passed and the amount of recources we need are running thin. America takes up only 5% of the worlds population but consume 26% of the world energy. There is a question of lifespan/quantity and quality. For the moment our population is good.

The following list will be from smallest emissins to largest. Agriculture 9%, commercial and residential 12%, industry 21%, transportation 27%, and finally electricity 29%. The emisions listed are all things that society feels we need, but the truth is, the exsesive amount of greenhouse gases we emit are harming us. The highest emissions we have had are from between the years 2007 and 2008. Since then our electricity and transportation have become more efficient.

The warming of the earth will cause methane release. 3. The melting of the greenland ice sheet. 4. the creation of more water vapor that acts as a greenhouse gas. and 5. the warming of rivers that will continue to warm the earth. All of these thing will cause severe reactions and will effect us greatly.
