The document discusses broadleaf deciduous forests and the effects of global warming. It describes the key features of broadleaf deciduous forests, including their location, average rainfall and temperature, and that trees lose their leaves seasonally. It notes that global warming will likely cause climate patterns to change and temperature to rise gradually. This could potentially cause many organisms and plants in broadleaf deciduous forests to die out, leading to the extinction of animals that depend on them. The document suggests various actions people can take to help address global warming, such as reducing electricity and water use, using renewable energy sources, and limiting car trips.
