We adults collectively have to decide the balance of how much the things we might enjoy are worth, compared to the world we want to leave for our kids and grandkids. There are so many things I'd like to affect to be better for them, and cannot. But, I can control how efficiently I burn fuel, and how badly I need to burn it. So I choose small, and small engined vehicles for getting around, and ride my bicycle as much as I can. I choose to no longer watch entertainment which apparently pollutes our planet. it's what I can do for them, for whatever positive effect it may have!
Whether by human effect, or natural evolutionary climate change, the world is getting warmer, that I understand first hand, for certain. As it continues, people are suffering more and more in many ways we did not imagine as recently as 50 years ago. I choose to be more a very small part of a partial small solution, than continue to be a very small part of the problem.
