Write the topic sentence of each paragraph.
Planting a tree benefits both individuals and communities in a number of different ways.But without a doubt, trees' most important benefits are environmental.Their leaves improve the quality of the air we breathe by filtering dust and other particles.They give off oxygen, too, which humans need to breathe.Leaves also absorb air pollutants, including ozone, carbon monoxide, sulfur dioxide, and carbon dioxide.The absorption of carbon dioxide is particularly important because the build-up of this gas contributes to global warming.Trees also absorb and store water.This reduces storm run-off and flooding.Trees recycle water, breathing it back into the atmosphere, where it forms into clouds and returns again as rainfall.Shade trees help to cool buildings and reduce the amount of energy needed for air condition-ing.In the winter, trees act as windbreaks, reducing heating costs.Consequently, trees lower the amount of fossil fuels needed to produce energy.Reduced use of fossil fuels results in a lower rate of global warming.
