Here's a thought is pollusion that's causing global warming or is it the fact that we are constantly building? We build houses, shops, centres, prisons, roads etc but is it too much? Yes, we do need these things, but it's the greenery that gives us oxogen and absorbs toxic things like exhaust fumes gases etc. Plant life also make us feel good. I think that's why Avatar is so beautiful, lots of forestry, wildlife, and no buildings. They, the Na'Vi people, are just getting on with there lives.
When you look at all the greyness (concrete roads, disused builings) how do you feel? sad? miserable? unhappy? It's like when the sky is grey, people aren't as happy as they should be. Just find something that makes you feel good. Watch a feel good film or feel good music, even smiling works. Try smiling even if you feel sad or down, just be careful where you smile and who you smile at. There are many ways, techniques to coping with stresses and strains of modern life you've got to find them for yourself, find what works for you...concider thing like reiki, meditation, relaxation classes,classical music, hebal teas, improving diet ( eating rubbish makes us feel that way...)etc.
