I agree that we should do something about the bad emissions. It's gonna be a hell if we keep going like this. However everybody can help the environment by using minimum electricity, which will even safe money. Don't use the car for anything like IvaN said, use public transport or just have a walk. And if you are using a car, dont use a fat 5L/mile engine (me looks at the US) and use good filters, there are filters and other tricks to lower your CO2 emission, many cars dont have them, it would be a good thing when that would be obligated to all cars.
Many say we cant repair the damage we made with with all the emissions but we can tho, if we are fast enough we can still fix a huge part we damaged, just simply by planting trees! a lot of trees, there are already organisations doing this only for fixing the environment which is a very good thing, with this they try to get the CO2 in the sky back to neutral.
Nowadays we can't without transport, we need goods from anywhere and people have to go everywhere atm. I dont like it that all this transport is emitting bad gasses which cause damage and problems in the environment, well I think nobody likes that, however many people dont really care about it or they don't really realise it when they emit bad gasses themself. I really hope for a good solution, I hope new fuel (or whatever) very soon, which doesnt emit harmful gasses, and if it does there should be a filter to bring the emission back to 0 and the fuel shouldnt be too expensive and it mustn't get scarce after some time like oil. Im really hoping that cold fusion in daily life will be reality, as it doesnt need much energy to get the process started and it is clean, safe, it has no bad emmissions, no bad radiations and no dangerous radioactive waste products. The only product by cold fusion is helium which is safe for humanity and ofcourse a lot of energy =).
I wanted to get myself a cool car once, a subaru impreza WRX to be right, but now after thinking, realising and talking with others I must admit with a pain in my heart that Im not very sure about it anymore, as it's a fuel slurper and I dont wanna fuck up the environment. Unless an alternative environment friendly fuel will show up in the future, my dream will become true

, if I still like the WRX that is
