We see trees most places we go! People have trees in their yards, at schools, along the highways, on farms, and in forests. Trees are sold at stores such as Walmart, Home Depot, tree farms, and nurseries. There are two types of trees, conifers and deciduous. Conifers are what we often call the evergreens. These trees keep their leaves and stay green all the time. The fir and pine trees are in this category. Deciduous trees usually change colors different times of the year. They also lose their leaves and grow new ones back. The oak is a familiar deciduous tree.
All trees have roots, bark, a trunk, branches, leaves and produce seeds. They must have the basics to stay alive and to grow. These include space for their roots to grip the soil and grow, soil for nutrients, water and sunlight.
We need to protect our trees. In doing so, we must realize that trees are essential for our environment. Many animals live and hibernate in trees. Birds build their nests in tree branches. Squirrels hibernate in the hollowed-out part of trees. Lizards, too, like to live in trees. Carbon dioxide is turned into oxygen by the trees. This aides in stopping pollution. In fact, in some countries such as Finland, trees are not removed when new building are constructed. They are kept thus helping with the environment. The roots of trees help to keep the soil in place, thus preventing erosion. It is well known that people of all ages have used the shade of trees to cool themselves, and their animals.
