#4--The Most Pressing Global Environmental Issue

I would have to say that the most pressing global environmental issue in my own opinion would be over-population.  It's not that I necessarily feel that over population is the biggest problem its that the more people there are in this world, the more problems occur and the worse current issues get.  For example, a few major issues that everyone is concerned about are:

-deforestation
-pollution and depletion of the ozone layer
-global warming
-h2O depletion
-killing off of species

There more people there are on the planet...
-more trees are cut down
-more garbage
-more oxygen being used
-more devlopment

"Overpopulation occurs when a population has exceeded its carrying capacity.  The entire planet and virtually every nation is already vastly overpopulated. Africa is overpopulated now because, among other indications, its soils and forests are rapidly being depleted—and that implies that its carrying capacity for human beings will be lower in the future than it is now. The United States is overpopulated because it is depleting its soil and water resources and contributing mightily to the destruction of global environmental systems. Europe, Japan, the Soviet Union, and other rich nations are overpopulated because of their massive contributions to the carbon dioxide buildup in the atmosphere, among many other reasons." http://animalrights.about.com/od/wildlife/a/HumanOverpopulation.htm

If I had a billion dollars to address a global problem, I would disprese it to people in our country to spend it however they please.  Life is too short to worry about every problem and to live scared about "what could happen" if we continue our ways.  I would spend some of the money on campaigns targeted towards elementary and middle schools, our next generation, on how they could make a difference in the world and make changes in their homes to help the planet.
