more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger‚ additional ultraviolet rays are allowed to pass through. These rays cause cancer‚ cataracts‚ and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970‚ Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on "global biogeochemical

CONSERVING DEPLETABLE RESOURCES Today we will discuss the ethics of conserving depletable resources. Points to be covered in this lesson: • It might appear that we have an obligation to conserve resources for future generations because they have an equal right to the limited resources of this planet. • • Conservation of resources Economic growth vs conservation • • • Future generations have an equal right to the planet’s limited resources By depleting these resources we are depriving

everything on earth will burn. The ozone layer is just as important to us as oxygen‚ without it the harmful UV radiation would give us server burns and destroy our delicate ecosystems. Even though there is hard evidence that proves that ozone depletion is harmful for organisms on earth‚ there are a few groups who think that the ozone layer is a “myth” aka doesn’t exist‚ others say that with or without the ozone layer life on earth will continue. But‚ they are wrong! Credibility: According to Dr

called Ozone Depletion Ozone depletion deals with the steady decline in the concentrations of ozone in the stratosphere due to its faster destruction by chemicals released by man into the environment. Depletion is mainly caused by chlorofluoro carbons (CFCs)‚ halons‚ methyl chloroform and carbon tetrachloride. There substances contain chlorine or‚ bromine which‚ can reach the stratosphere. These elements are capable of catalytically breaking down ozone into oxygen. Ozone depletion can also be caused

California is in a drought and farmers believe our only option is to take water from under the ground. But‚ groundwater depletion is causing a lot of bad things to happen. It is making the layer of clay above collapse‚ when the clay collapses the dirt above gives way and sinks. This sinking causes sinkholes and is very dangerous. The sinking also damages pipes‚ buckles walls of irrigation canals‚ and cracks homes. Although the sinking is already a big enough threat the water in general could

We should save natural resources because if we don’t‚ life will die out Have you ever wondered what would happen to the earth if we used all of the natural resources? Is it a possibility that this would happen in the near future? Well‚ at the current rate of resources being used it might happen. Renewable resources can Be used more than once. On the other hand non-renewable resources cannot be restored after being used once it’s used. Additionally non-renewable resources are in limited

History of Natural Resources Management in the United States By Peter T. Smith NR1 When North America was first settled and colonial development began‚ during the 1700s‚ forest covered about 40% (820‚000‚000 acres) of the nation not including Alaska. The eastern part of the states was the first to be settled. Settlers had many obstacles to overcome and most critical of such obstacles were how to feed‚ warm‚ and shelter themselves. The answer to these problems for them at this time was forest. Forest
