than 50 percent of the tree cover has disappeared due to human activity. Although humans have been practicing deforestation since ages‚ it was in the mid-1800s that forests began to be destroyed at an unprecedented rate. As a matter of fact‚ throughout the earlier part of the medieval age‚ Europeans used to live amongst vast areas of forested land. But later‚ they began deforestation at such a high rate that they started to run out of wood for cooking and heating. Also‚ due to the depletion of

demands are bound to grow.Industrialized countries‚ with higher living standards and greater numbers of cars‚ produce far more air pollution and greenhouse gases than developing countries. Developed countries also contribute to overfishing and deforestation . But these countries can reduce serious environmental hazards by using technology such as smokestack scrubbers‚ emission systems‚ and waste-water treatment plants. Although developing countries consume a far smaller percentage of the world’s resources

[edit] Minerals and oil Materials removed from the Earth are needed to provide humans with food‚ clothing‚ and housing and to continually upgrade the standard of living. Some of the materials needed are renewable resources‚ such as agricultural and forestry products‚ while others are nonrenewable‚ such as minerals. The USGS reported in Materials Flow and Sustainability (1998) that the number of renewable resources is decreasing‚ meanwhile there is an increasing demand for nonrenewable resources

Early in human history‚ people used energy for heating‚ lighting‚ and cooking. As humans began to farm larger areas of land‚ their energy demands changed. Domesticated animals were used for energy sources to pull plows. When the Industrial Revolution occurred‚ people’s energy demands further changed to meet the needs of industry. Work that was done by people and animals were then transferred over to machines. These machines required more natural resources such as iron and coal to produce large amounts

rainfall * Gully erosion – occurs where there’s intense rainfall and little vegetation cover. Force of water cuts gullies in slopes :O! * Wind erosion – occurs in dry parts of world * What makes soil erosion worse? * Deforestation and removing vegetation. As a result of this soil gets exposed to wind/rain * Overgrazing by animals. Result is same as above * Over cultivating the soil! Especially monoculture which weakens the soil and structure and removed

It is important to recognize the detrimental effects that come with deforestation; extinction of specialized species‚ loss of biodiversity‚ soil erosion‚ loss of habitat‚ and climate change are all serious matters that can no longer be thrown under the rug. Although the timber industry relies on trees‚ they should not be seen

Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing‚ which may prevent the growth of young trees. Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth’s land animals and plants live in forests‚ and many cannot survive the deforestation that destroys their homes. Deforestation also drives climate change. Forest

Climate Change in Nigeria Climate change has always occurred in different Nigeria; however the effects have become more noticeable recently over the years. The effects have affected the daily lives of many for better or worse. A peer reviewed research done by an unknown source‚ which was accepted by the Journal of Geography and Regional had concluded that the average temperature of Nigeria has increased by 1.7°C in the period of 1901-2005. The increase has however been higher in semi-arid areas

Bukit Katil. I enjoyed cycling along the roads that ran parallel with rows of tall trees. The atmosphere around me was refreshingly cool. In the midst of admiring view‚ I caught the sight of a house that was partly buried in the mud. I halted (stop) and looked at the house from a distance. I hesitated for a while before I went to look for a phone immediately. I managed to find one and called the police. Since it was quite a remote (isolated) area‚ it would take sometime for the police to reach
