Yes, those stats came from the documentary. While the documentary isn't the most exciting film to watch, I do think it's educational and important. One of best things Al Gore does in this is address what the skeptics say, and point out why they are wrong, backed up with data. Meanwhile, I still can't find a study that doubts humans are the cause that isn't based on funding by oil and energy companies or a group pushing so-called conservative interests as their agenda. I'm no scientist, so I have to trust the experts here; to me, that means I believe humans are a significant cause of global warming.
The point is, whether or not anyone believes humans are the cause or not, if it continues as it is, we're going to have some major problems. Maybe we won't see the worst effects in our lifetimes, but that doesn't mean we don't have a responsibility to do something for future generations. And I would rather it be that humans are the cause; at least then we have some control over the matter and we can do something about it.
There are a number of things we could easily do:
- We could start by raising vehicle fuel standards in the US to something more in line with what other developed countries have (ours are very low).
- My office and my school's labs leave their computers on all night. Why?
- Replace light bulbs with compact fluorescent light bulbs. They cost a little more, but are much more efficient and last years longer.
- As needed, replace appliances with more energy-efficient models.
It's not too difficult for one person to do their part, and if enough do their part, it'll make a major impact.
