Forests provide essential habitat to wildlife, produce oxygen, act as carbon sinks, control pollution and prevent erosion. Forests are also a source of many useful products and are an important part of the economy.Know More
Forests help preserve biodiversity by providing habitat to many diverse species of wildlife. The Amazon rain forest, for example, is home to nearly 1,300 species of birds, over 400 each of mammals and amphibians, over 300 reptiles and millions of insects.
Because trees use carbon dioxide for photosynthesis, forested areas clean the air of excess carbon dioxide and produce oxygen in return. Because trees have long lives and contain carbon in their tissues, they sequester carbon, acting as carbon sinks. Forests also help clean the air of other pollutants and provide excellent barriers against noise pollution.
Soil that might otherwise be lost to wind and water is held in place by the deep roots of trees. By slowing water runoff, forests help the surrounding land absorb more water. As of 2005, global forest product trade was near $400 million, and 30 percent of forests worldwide saw exclusive use for the harvest of forest product, illustrating the economic importance of forests. In addition to timber, forest products include foods, rubber, resins and medicinal products.Learn more about Natural Resources
Canada has an abundance of natural resources, including minerals, rare earth elements, wildlife, coal and hydropower. Minerals and elements mined in the country are iron ore, silver, copper, nickel and gold. Other natural resources include fish, molybdenum, diamonds and potash.Full Answer >
Hydropower is clean, renewable and the lowest-cost way to generate electricity, but hydropower also requires damming of rivers, which destroys wildlife and changes the natural cycle of the river flooding. It can also cause changes in the composition of water.Full Answer >
Some general names of forests are tropical rainforest, temperate deciduous forest, temperate coniferous forests, alpine forests and boreal forests, which are also known as taiga or subalpine. Forests are named or classified according to their environment and the types of trees that grow in them.Full Answer >
Resources that are commonly accepted as being scarce throughout the world include water, food and forests. Oil and natural gas are also growing increasingly scarce. To an extent, however, resource scarcity is contextually subjective. In wealthier places in which people can afford to pay premium prices for resources that may not be in plentiful supply, the shortage is not likely to be felt as severely as in economically deprived locations.Full Answer >
