How would you say our attitude about the environment has come in the past 60 years or so? Do you think people care more about the environment now than they did back in the 1940s? Also, how about things like smog taxes, and other laws that make it attractive to use renewable energy. None of those laws existed back in the day. Doesn't that mean that progress is being made on improving the environment and how we treat it? Also, I don't think factories pollute the water as much as it used to. Yet another sign of progress.
