Mmm. I understand how you feel because I used to feel that way too, but fter I saw pictures in Time Magazine of world changes and learned how quickly all of these events happened, I was very disturbed and alarmed
Even if we stop all of the bad things we have done in the past that hurt the planet, upcoming industrial countries like China and India could choose to do the same things we did and therefore continue to alter the planet.
It will be an interesting planet in 30 years when I will be approaching retirement. I wonder what the country/world will look and be like.
