But did you know that trees also help us save energy and reduce air pollution? Saving energy. A big, leafy shade tree helps keep us cool during the summer. If that tree is shading the whole house, that means we don't have to use as much electricity for air conditioning. Trees also help keep us warmer in the winter. Many schools have rows of evergreen trees around their buildings to a block the cold winter wind. Reducing air pollution.

Trees take in the carbon dioxide for their own food - then turn it into oxygen for us to breathe! Planting a tree is a great way for kids like you to make a big impact on the environment.
