If producing nuclear energy produces too much radioactive waste, you need to lock up the waste somewhere (like a couple of miles underground) so as not to negatively affect living conditions. Atomic bomb testing in the open atmosphere was not smart. But, nobody does that anymore. Producing electricity from nuclear energy has addressed the radioactive wastes so that they don't affect the environment, they need to be stored away from people, like a few miles underground isolated from natural underground water reservoirs.
In the main, the other things that modern man has done to the environment has been self limiting. Take Beijing for example, the air pollution is so bad that there is a general decrease in population over the last few years. People will continue to move away from such polluted areas until the offending industries clean up or close up. I remember the river in New Jersey that caught fire in the 1970's and precipitated a clean up effort that was effective and that river (wish I could remember the name) is pristine clean today. Remember Pittsburgh? When I was there 30 years ago, the river stank from pollution.. Last time there was amazing, with a riverwalk and all. Modern man usually sees its mistakes environmentally and corrects them.
