Trees are good

Trees are good because they keep our air supply fresh. By keeping our air supply fresh they take in carbon dioxide and store it. Trees keep our environment fresh. I found this really interesting, in one year, a tree can absorb as much carbon as is produced by one car that has driven 26,000 miles. Think about how much carbon hundreds of trees have absorbed in one year or even a month. Two full-grown trees can provide enough oxygen for a family of four. One tree can produce nearly 260 pounds of oxygen each year.

Trees are good in other ways too. Trees lower air temperature by evaporating the water that gets on their leaves. So the air temperature would be hotter if we didn’t have as many trees. We need trees or our air supply wouldn’t be fresh.
