Today, while at the Oregon zoo, we visited the polar bear exhibit. In addition to a few polar bears, the exhibit displayed some information about how dramatically the ice cap has shrunk over the last 20 years and the problems this is causing for the polar bears.
Shortly after leaving the exhibit we went to lunch at the cafe, and while waiting for our lunch to be prepared Travis asked why the ice was melting. We explained the whole "burning fossil fuels releases carbon dioxide which causes the atmosphere to trap more heat" problem, and the different kinds of fossil fuels we use and why. April also explained the different ways electricity is generated and the fact that burning coal is the most popular way in the U.S., and reminded him of all the coal trains we saw when riding on the train to San Francisco.
After a few moments Travis stated "I know how to keep people from getting their electricity from coal, tear up all the tracks the coal trains run on!"
Good thing he's too small to use a crowbar.
