Sometimes, not always. If I improve my temperament, or if I help get someone an education, or if I help get an unjust law changed, or I raise awareness on some issue, these actions don't cause someone to get meaner, someone to lose their education, someone to make a bad law, or someone to hide an issue.

For environmental issues, I see your point. I hope that actions on conservation don't get 100% canceled out. Even if they're 90% canceled out it still buys us a little more time.
