Why has the EPA not done a study of the hundreds of millions of CFL lightbulbs with mercury in them which will be dumped into the ground when they burn out? Also why has the EPA not done a study of the impact of aritficial turf when it is dumped due to the fact that it contains lead? Also, what is the environmental impact of removing real grass that makes oxygen, and the heat generated by artificial turf during the summer on global warming? Also, when it rains on artificial turf surface pollution goes into the water drains as runoff. What part of the "Environmental Protection Agency" did I not understand?
