Demonised present vs romanced past

I want to make this super short. I don't think it's fair to the present and perhaps the past was not always pretty. Instead of just blaming it all to the current norm and finding an easy escape from the work, let's just get over it. If broken, let's fix.

Back in the days it was all green. We had trees all over the place. Look at that now, we are doomed...

Did you ever plant a tree? If not, let's do it. If planted one, why not do more? It would be a great start. The present can be improved. Heck, it can even become better than the past. It's all about the willingness to make a change and it starts now.
