The impact of any one individual's environmental choices on my life is basically zero. People in aggregate matter, but individuals have minuscule effects. At least, for the people that I interact with. Things might be different if I spent a lot of time chatting with Senators. But I don't.

Besides, this claim proves too much. Everything that everyone does can in some possible way affect me. Want to live alone in the woods cut off from human society? You're depriving us of your wisdom so the next generation will grow up more ignorant.
