Have you ever looked out of the window of a passenger plane from 30,000 feet at the vast expanses of empty ocean and uninhabited land, and wondered how people can have any major effect on the Earth? I have. It is now becoming pretty clear that we are causing a great deal of damage to the natural environment. And the planes which rush us in comfort to destinations around the globe, contribute to one of the biggest environmental problems that we face today— global warming.
As usual, people in the developing world are having to deal with problems created mainly by those of us in developed countries. Beatrice Schell, a spokeswoman for the European Federation for Transport and Environment says that, "One person flying in an airplane for one hour is responsible for the same greenhouse gas emissions（排放）as a typical Bangladeshi in a whole year." And every year jet aircraft produce almost as much carbon dioxide as the entire African continent does.
There is a way of offsetting(抵消) the carbon dioxide we produce when we travel by plane. A company called Future Forests offers a service which can relieve the guilty consciences of air travelers. The Future Forest website calculates the amount of CO2 you are responsible for producing on your flight, and for a small fee will plant a number of trees which will absorb this CO2.
Yesterday I returned to Japan from England, and was happy to pay Future Forests 25 pounds to plant the 3 trees which balance my share of the CO2 produced by my return flight. Now the only thing making me lose sleep is jet lag.
