Tropical fruit trees are among the most popular and include, avocados, grapefruits, mangoes, and oranges. Cooler, temperate regions have fewer kinds of fruit trees, however, orchards in North America do produce vast amounts of apples, cherries, and peaches. Almonds, pecans, walnuts, and macadamia nuts are a few easily recognized species of nut producing trees. The most important nut tree of warm regions is the coconut palm, which produces coconuts. Trees also supply chocolate, coffee, maple syrup, and such spices as cinnamon.
Trees also have a role in conservation.
Along lakes and rivers tree roots conserve soil, holding top soil in place, and water, holding water in the ground. Where they grow in open country, they act as windbreaks and keep the wind from blowing away topsoil, therefore aiding in stopping desertification. Trees in the world's forests also provide food and shelter for wildlife. 2000 EcoWorld , All Rights Reserved EcoWorld and EcoWorld Tours are registered Trademarks of EcoWorld Inc.
