You're speaking right from my heart. We talk about all these issues like climate change, ozone hole, Greenhouse gas emissions, rising global temperatures, rising sea levels, biodiversity loss, fossil fuel combustion and so on while the problem can be described with one single word: humans. Reminds me of that old joke where two planets are talking to each other. One says “Buddy you look awful what's wrong with you?” “I caught homo sapiens.” “Ouch that's bad but don't worry that always passes as fast as it came.” Who knows maybe today in a million years or so some radioactivity resistant and now evolved bugs will find fossilized humans and ask themselves “Why did they extinct? They had quite large brains.” “The last signs of human life were detected at the same time, when a lot of huge radioactive craters suddenly showed up all over the globe.” “Poor bastards, probably asteroids, they never had a chance.”
