Human population has been steadily rising since the Industrial Revolution; the United Nations estimated that there were over 7.3 billion people in the world in 2015 and predicted that the population will rise to a potential maximum of 16.6 billion by 2100 (United Nations). Such an increase in population results in a similar rise in the demand for food. In order to avoid a potentially catastrophic famine‚ food production needs to increase in order to feed all of the new mouths without placing excessive

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

Nevertheless‚ many tropical areas around the world‚ similar to these treasured rainforests‚ are being cut and degraded for timber‚ palm oil‚ pulp‚ rubber‚ minerals‚ and other materials. The action of deforestation is prompt to endanger the existence of valuable species. Not only that‚ deforestation is also being matched with illegal wildlife trade as forests provide easy access to more land and remote areas (WWF‚ n.d). This resulted in several severe consequences mainly habitat

Another driver of climate change and loss of biodiversity is deforestation‚ the cutting down of trees to make room for agricultural land is simply adding to the amount of greenhouse gases worldwide‚ especially where there is an increase in farmed ruminant animals like cattle and sheep. Deforestation is a major cause of the loss of biological diversity and is a significant global concern (Brockerhoff‚ E.G et al

An issue in the world today that is extremely troubling is the deforestation of the Amazon Rainforest. The world’s largest remaining natural resource is at risk of total destruction. This beautiful South American forest represents 40% of the continent and 54% of the total remaining rain forests that are left.

The rainforest destruction has been greatly disturbing to the indigenous people. Their cultures and traditions have been forgotten‚ due to the relying of the city life. Therefore‚ city life would be enhanced greatly‚ crushing and disrupting the old traditions. Without traditional foods and methods to sustain food‚ indigenous people have to integrate with mainstream societies. Once the rainforests have been logged‚ settles would greatly claim for the logged land. Due to the activity or agriculture

Chapter 11 : Soil: The Foundation for Land Ecosystem Chapter 11 Brooke Settles Chapter 11 discusses three major practices that expose soil erosion and how they can be corrected . The three are Over- cultivation‚ Overgrazing and Deforestation. These are each all major problems in creating an unsustainable society. The good thing is that each of these causes of erosion can be corrected to create a more sustainable society. First there is Overcultivation which is the practice of repeatedly

Experts estimate that the last remaining rain forests could be consumed in less than 40 years. Obviously‚ deforestation has been becoming an alarming phenomenon for the whole world. Writing about this issue‚ Laura Lopen‚ John Maier and Dick Thompson express some quite strong opinions. In “Playing with Fire”‚ the authors indicate that the rain forests of the Amazon

rainforest which has already lost 20% of its area forever. Deforestation is the single biggest threat to the rainforest; the prime cause of it is cattle ranching. This is when land is cleared to provide space for cattle ranchers to herd their livestock to help increase beef production. This activity accounts for 60% of deforestation in Brazil‚ which is having a major effect on the biodiversity of the ecosystem. The impacts of deforestation are wide. In the Amazon there have been problems with increased
