In particular, deforestation threatens to reduce these numbers of species, degrade the genetic diversity of individual species, and hinder the survival rate of species already exploited in their wild form in the forests. Major consequences arise for plant and animal species as a result of deforestation. All forms of disturbance displace animals from part or all of their territories.
The more extensive the disturbance, the more likely animals in an area will become overcrowded and their populations will decline due to social pressures, limitations on food, and impaired reproductive activity Grainger Even by just removing a few plants, the complex annual calendars of food sources could be disrupted. Furthermore, genetic diversity of individual species is also being degraded.
This is a concern to plant breeders because several of these species are commercially valuable crops Grainger Crops that grow on the outskirts of the forests have been bred from wild plants to give the best yields under particular environmental conditions. Extracts from the wild plants have been taken in order to make use of specific genetic characteristics from the entire population. Also, some high yielding rice varieties last only two years before being attacked by a new insect pest and needing replacement Grainger Deforestation is increasing the rate of species extinction so that the plants we are using will disappear along with many animals also.
It occurs naturally at a rate of about one species every two years Species are put at much risk early on when their numbers drop so low that they could be eliminated by drought, disease or other random events. There are many endangered species found in the tropical rainforests that risk extinction if the present conditions continue.
Some examples are the koupray or wild cow of Southeast Asia, of which only individuals remain, the broad-nosed lemur from Madagascar, which is down to just two colonies, and the southern bearded saki, a monkey living in the forests of the northeast Amazonia Many medical advances have come from the abundant botanical resources of the tropical rainforests.
Extracts from organisms are used directly as drugs for many maladies ranging from headaches to lethal diseases such as malaria. In addition, chemical structures from organisms serve as templates for which scientists can chemically synthesize drug compounds.
The blueprint for aspirin is found in extracts from willow trees in the rainforest for example. Finally, the plants of the rainforest provide aids for research. Deforestation also contributes significantly to the greenhouse effect and global warming.
To begin, the sun emits short wave radiation through the atmosphere to the Earth. Certain trace gases such as carbon dioxide, methane, ozone, and nitrous oxide retain heat by trapping some of the infrared radiation.
Clearing and burning rainforests releases considerable amounts of greenhouse gases into the atmosphere. Deforestation is also responsible for destroying our means of absorbing and storing the substance. This leads to global warming because the Earth has lost one of its only ways to absorb excess atmospheric carbon. Through photosynthesis the rainforests absorb the carbon dioxide and emit oxygen. Rapid warming of the atmosphere can have tremendous consequences. First, many species will not be able to survive the climate change or may not be able to continue life in another habitat.
They also provide good things for humans and for the environment. Deforestation disrupts the carbon cycle. The forest trees take carbon dioxide as well as pollutants from the atmosphere. When the trees are destroyed or burned or left to rot, carbon is released into the air as C02 and methane. Methane and C02 contribute to the greenhouse effect. According to the World Rainforest Movement, twenty-five percent of our medicine comes from the forests.
Deforestation affects our water, too. Trees take up water from their roots and then expel it into the air as moisture. This moisture then gets converted into clouds that will bring rain. If we have fewer trees, the atmosphere will be drier. With fewer trees, our soil does not have as much support and much silt is released into the waters, resulting in loss of soil and more flooding.
And, what happens to the animals that make a home in our trees? Where do they go? Try to imagine the earth without our trees, not just because of the things above, but also for the beauty of nature.
Here is your Essay on Deforestation! Deforestation is the permanent devastation of native forests and woods. Deforestation happens in many ways: when trees are cut down to grow crops, for livestock, logging so wood can be used for building things like houses and furniture, for roads and neighborhoods, for firewood, and forest fires.
Deforestation essaysEarth without forests is a picture that most of humankind presently could not conceive. Forests cover much of the planet's land area. They are extremely important to humans and the natural world. However, deforestation has been consuming our forests. Deforestation brings abo.
Deforestation Essay 1 ( words) Deforestation is the removal of forests on a big level by cutting down plants or burning of forests for fulfilling the personal needs. The word deforestation is used to describe the process of cutting down and burning the trees in forests and woodland and converting.

Deforestation, as the name suggests, is the clearing of forests and trees from an area for various commercial purposes. List of the Most Impressive Deforestation Essay Topics for College. The trees provide vital regulating ecosystem services, including stabilizing microclimate, soil structure, and atmospheric composition.
