Trees make our lives more pleasant. They're beautiful to look at, and they can provide shade or a good hideout. Forests cover 30 percent of our planet, concentrated mostly in 10 countries: the United States, Canada, the RussianFederation, Brazil, China, Australia, the Democratic Republic of Congo, Indonesia, Peru and India [source: United Nations Environment Programme].

That may sound like a lot of forest, but worldwide, our forests are disappearing. About 13 million hectares of forest -- an area roughly the size of Greece -- disappear every year. Deforestationhappens because of population growth and increasing agricultural and industrial demands; trees are cut down to make room for new developments.
Why does it matter if trees are planted or cut down? Trees provide us with wood, fuel, food, medicine, latex and other products used in our daily lives. They also affect our climate. No, they can't make snow on a sunny summer day, but their very existence -- or removal -- makes a difference.
Climate isn't the same as weather. While weather is short-term, like the five-day forecast on the evening news, climate is the weather pattern over a long period of time, usually 30 years. And the climate of our planet is warming -- heating up by approximately 1 to 1 1/2 degrees in the past century [source: The Weather Channel].
In the next section, let's look at the ways trees positively and negatively affect our climate, and, in turn, our weather.
