I just saw this movie last night. To those who don't know about it, it is kind of like a documentary on global warming. This movie was made to try to get people to change the way they live, and have a less adverse effect on the environment.
It's great that such movies are made and I hope that many people watch it and start to reduce the amount of CO2 that we as humanity produce. I am pessimistic, however, that we can actually overcome this problem of global warming, even if we all make changes in our lives. We can reduce the impact we have on the planet, but only up to a point.
Humanity needs to burn the fossil fuels just to get even the most basic of necessities, like the food we eat, or to move around. We can burn less of it, but we still need to burn it every day, and global warming tends to have a kind of snow-ball effect. The problem is that there are simply too many of us. Nonetheless, watching this movie and reducing the pollution each individual causes and amount of fossil fuel each individual burns, is still a good thing.
