I'm in favor of the fossil fuels/petroleum being the biggest issue currently. If you think about it, many of the "enviromental issues" today are a result of petroleum and its by-products.
Our oceans: Ever researched the Pacific Garbage Patch (Pacific Gyre)? It's an unbelievably huge trash deposit located at a spot in the ocean where there is hardly any current. What kind of trash? Plastic...of course. And the scary part is it will be there forever since plastic doesn't break down.
Our air: Whether you believe in global warming or not, emissions from petroleum (factories, engines, etc) are severely damaging air quality. I recently learned that in addition to the well known fact that plastic doesn't biodegrade, neither to emissions.
Our land: Landfills are full of plastic (which again doesn't break down). Chemicals from petroleum and its by-products are poisoning the earth, its animals, and ummm...us.
All around, it's pretty scary stuff.
