The high demand for more farmland helps drive the need to cut down more trees, which in turn, contributes to deforestation. Tropical forests have the highest impact rate when it comes to deforestation due to agriculture. In the tropics, only the topsoil is highly fertile, so when the nutrient-rich soil is gone, people cut down more trees to find more fertile topsoil. Tropical forests lose thousands of acres daily due to agricultural use. One way people take out trees for agriculture us is a process called “slash and burn”.
The effects of climate change, biodiversity, and human life inside the rainforest are the most important reasons for regulation of deforestation. Deforestation greatly affects climate change around the world in many ways. First, tropical forest trees have a lot of stored carbon; trees need carbon to grow. Trees take in carbon and let out oxygen. When they are cut down the carbon is released into the air as carbon dioxide (Ucsusa).
The Devastating Environmental Effects of Deforestation The government enacting stricter conservation laws helps end deforestation problems such as the destruction of wildlife, forest fires, flooding, and increasing global temperatures. With the population rising quickly, demand is rising globally for biofuels, food, and living space(“The World”2). Deforestation is there to solve the problem, but not without a hefty cost. As of 2013, every minute on earth 50 football fields of forest vanishes do to the clearing of trees, possibly for products such as paper or wooden furniture (Environment News Service. 2).
A recent study of the Brazilian Amazon predicts that up to 90% of extinctions will occur in the next 40 years (WWF). One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat. It was estimated in 2003, 70% of Earth’s land animals and plants live in forests, and many cannot survive the
Do you know that agricultural lands cover 31% of the earth? And because of deforestation processes these lands are disappearing. Deforestation is defined as removing the forests which includes trees, and plants to make the land accessible for different uses. Forests are important as it is a home of many creatures and it also surrounds the earth with large quantities of oxygen and the disposal of carbon. Some species are suffering from deforestation actions because they depend on these trees and plants as a shelter and as a food source.
One of the main causes of deforestation is agriculture. Forests are cleared to be converted to plantations. The plantations can be for palm, grain, rice, corn, and other crops. With the huge increase in human population, the needs of food grow rapidly. Every day, more than seven billion people have to eat.
An estimated 18 million acres of forest are lost each year, due in part to logging and other human practices, destroying the ecosystems on which many species depend. Habitat loss is a result of deforestation, which is als caused from exploitation of resources, agricultural conversion, and urbanization. It is a largest factor contributing to the loss of biodiversity. Large scale infrastructural developments and the expansion of settlements contribute to deforestation, therefore habitat loss. For example, between 1984 and 2017 about 30% of forests are cut for human settlements.
Deforestation brings many effects either to society or country. It impacts a country’s economy, the life of community, environment and extinction of species. The causes of deforestation are logging, agriculture croplands and pasture expansion, urbanization and more (Ebenezer 2015). Some methods used in deforesting are burning the trees or clear cutting the trees. Food and Agriculture Organization (FAO) (2005 cited in Ebenezer 2015) reported that the global forest area is around 4 billion hectares corresponding to 0.62 hectares per capita, but it is decreasing by 13 million hectares per annum.
2.1.1 Deforestation in Ghana Numerous legitimate concerns have been raised about the devastating environmental impact of extensive destruction of forests. Scientist, economist, environmentalist and many others have deliberated that the prevailing patterns of deforestation are bound to wreak havoc on the earth as the home for mankind and as the source of sustenance (Broader 1989). Deforestation is a serious problem bedevilling the world and it is simply defined as the conversion of forested areas to non-forest land use such as arable land, urban use, logged area or wasteland (Tejaswi 2007). However, deforestation in sub-Saharan Africa is by no means a recent phenomenon. As far back as 450 B.C Herodotus document losses of forest resources in
Pesticides and fertilizers: Many farming activities engage in the application of fertilizers, pesticides for higher crop output. When we want to get higher amount of food we need fertilizers. However, in some ways this also damages the land. Sometimes when small insects die with fertilizers, the other animals eat them and they died.
