Really, only here in the US can we "afford" to actually pay attention to the environment
. Don't read that statement wrong - you should care about the environment
and take appropriate measures to protect it... but lets be honest... about 90% of the world simply dumps their trash in the ocean, same with oil and billions of gallons of carcinogenic and harmful chemicals. Lets not even talk about trash collection and recycling... still pipe dream.
It would be wonderful if there was no way for other countries problems to show up on our shore but look at Fukushima and all the radioactive stuff that has washed on on the west coast
of the US - its not going to happen.
Oil, trash, heavy metals, radiation does not care about laws and borders... it will go anywhere it will go.
