You can change the world, too

Tom Friedman said, world is getting hotter everyday, and one of the main cause of the greenhouse effect is the carbon dioxide (CO2) which is created by human. This article tells us the things we could do to make Earth healthy.

The third consecutive Spare the Air Day was called for Friday as hot, stagnant air remained in the Bay Area.
Both Wednesday and Thursday were also Spare the Air days, after a cool summer had brought only two before this week
With ozone levels in the air expected to approach unhealthy levels, the Bay Area Air Quality Management District declared a Spare the Air day for the region.
The agency encourages people on Spare the Air days to take bikes, public transit or carpools instead of driving solo, to cook indoors rather than barbecue, and to avoid using aerosol sprays and gas-powered gardening equipment.

 We could prevent releasing a huge amount of Carbon Dioxide by following those suggestions. I think the citizen of the United States cannot just rely on government to solve this environment problem, so we have to act first, show government how much we care about the environment, and then eventually, they will use some money on this situation.
