Just a quick one:
Read a hilarious article on Cracked.com about the 7 most retarded ways celebrities have tried to go green. An interesting question raised was whether planting trees to offset pollution was really a viable solution. As it turns out, although it may make celebrities feel better about their wasteful habits, it doesn't help the environment all that much. To reduce our impact on the environment, we might even have to make lifestyle changes.
Don't get me wrong, planting trees is a good thing. But in addition to that some of us will have to cut back on our private jet trips, and for those of us - like me - who have rather smaller budgets to work within, switching off lights and geysers when not used, using the microwave rather than the oven, and sensible use of energy-saving lightbulbs are a good start.
