I came across this idea, and I think it is a good one. When you are stuck at a rairoad with a long train, turn off your engine! Turn it back on when the last traincar goes by. It may not stop pollution and we still would burn a lot of energy, but if we get lots of people to do it, It would make a big difference! Bit by bit, we can fix global warming.

When I was in a store, I noticed lots of shelves filled with energy saving lightbulbs. There were about 100 bulbs. I am glad people are starting to help save energy more.

I have recently found out that some parts of global warming are caused by cows. With all their stomachs, they release methane to heat up the world. Since we eat so much red meat, it is causing a large problem.
