This means that the available land is under stress to develop food for the higher population, meaning that the land is over-cultivated and so aids soil erosion. For example, intensive cultivation of land in the soya plantations in South America can lead to overcropping. In South America, the soil is fertilised, although the use of chemical fertilisers Is not advantageous to the land as much as manure is. Due to the overuse of fertiliser and the underuse of manure, the soil structure gradually becomes more damaged due to the effects of overcropping. The effects caused by overcropping can be lowered through the use of organic manure, i.e cattle dung, to the soil through irrigation.
When Diamond refer to the Mayan collapse as “Malthusian” he is saying population growth is increasingly higher than agriculture growth. Stating “Too many farmer grew too many crops on too much of the landscape.” This means the depletion of trees and hillside erosion causing more environmental problems for the Mayan people. Decreasing useable farmland creating a manmade drought through deforestation and soil problems. e.What are some of the parallels between the Mayans and modern societies? Provide
Because of this demand, their living space needs to be expanded in order to grow food and provide homes for people. Hence, deforestation increases. This is another effect of overpopulation that impacts the worsening of the environment . For example decreased forest size increases the amount of carbon in the environment. More specifically, deforestation affects the wildlife and results in biodiversity loss and species extinction .
Trees are being cut down at a very fast rate and we need to do something about it before it is too late. Deforestation has a major effect that is harmful to the world’s atmosphere (TS). Global warming is a result of deforestation and a main factor in hurting the atmosphere. Trees take in and store carbon dioxide, while producing oxygen
A Proposal & Annotated Bibliography Although there are positive impacts and effects of Deforestation so that we gain more land to cultivate crops and fed thousands of people, I claim that Deforestation can cause negative effect to the people and other living flora and fauna because due to deforestation nature is experiencing serious drought that directly causes negative impact on the people and the natural ecosystem, it causes global warming which is one of the serious environmental issues in the present context and causes soil erosions like landslide, floods etc that directly concern with the health and safety issue of wildlife as well as peoples.

However, the Europeans took the Indians’ methods to increase soil nutrients and destroy plant diseases and pests, such as, “annual burnings” (Cronon 90) and drastically increased the intensity and speed at which they were performing it. As a result of this, there was a massive reduction in trees, animals, and farmland. Specifically, trees were at a loss, as they were used for many different things, such as, “ship’s masts” (Cronon 109). Due to the high demand for wood, much of the land was, “‘generally cleared’” (Cronon 113). This loss of trees and forests affected several other aspects of the environment.
Land pollution causes the land’s productivity and potential to decline to such a level that the purpose of utilising lands for building infrastructures, housings, services, agriculture, forestry and many more for the development of human being are no longer achievable (Prabhakar, 2012). Land pollution are resulted by some sources which are deforestation, mining and construction activities. Deforestation appears to be the major concern as once the land is converted into dry lands, it can hardly be made fertile again. Those areas inevitably end up as waste lands. Mining requires the removal of topsoil containing valuable organic matters.
This is in more than one way that they are harming they cause air pollution: “ the fossil fuels used in energy, transportation, and synthetic pesticides/fertilizers emits 90 million tons of carbon dioxide into the atmosphere every year. On a lesser note, factory farming also releases harmful compounds like hydrogen sulfide and ammonia that can cause immediate negative health effects in humans”(5 Ways Factory Farming is Killing the Environment by Kate last name N/A). If the factory farming keeps going and keeps damaging our environment it could cause some really big issues because it will cause more depletion of the ozone layer. Another way that the factory farms are causing harm to our environment is by water pollution: “Industrial agriculture sucks up 70 percent of the world’s fresh water supplies. To follow up that staggering number, the EPA estimates that 75 percent of all water-quality problems in America’s rivers and streams.
This result not only loss ecological balance but also impact directly on human societies. In the environment aspect, firstly they disturb animal habitats leading to ecological destruction. Furthermore, forest fires contribute to global warming which has the devastating effect on the planet. In term of economy, when fires approach homes can burn properties and damage to forestry areas, the whole communities have to be evacuated. The last one is effect on society.
Imagine a world where the local wildlife are decimated because of increased carbon dioxide in the atmosphere due to waste byproduct disposed of by factories and leaking of oil reserves into rivers. The air we breathe is no longer safe, and everyone must wear oxygen masks. There is no longer access to clean water, and citizens must resort to drinking out of dirty water sources. The energy resources we use today and have used since the beginning of the Industrial Revolution are continually wreaking havoc on our planet. They are terrible for animals, humans, and the atmosphere alike.
