What is how one can understand that the problems of the deforestation are due to the lack of natural decomposition. During the next 100 years, the accumulated toxic substances will accumulate in the atmosphere. The exact path of the accumulation of harmful substances into the atmosphere is not yet determined. But it is known that accumulation of organic substances into the atmosphere is characteristic for most countries of the world.
In regions such as Southeast Asia and the Amazon, the dead branches of the tree commonly produce harmful substances which are transformed into harmful by-products during the plowing and burning. At the same time, some forest ecosystems may undergo severe damage due to the accumulation of waste organic matter. It may be mentioned in an essay on diseases caused by water pollution that many species of insects, birds, insects, and other insects eat the leaves of the plant. These harmful substances cause awful consequences for the environment: heat, electricity, mold, and other negative effects on the environment.
Nowadays, agricultural activities include processes leading to a rapid reduction of humus in soil and the release of CO2. Agriculture-provoked pollution can be considered as one of the most significant factors that lead to global warming and one of the main environmental problems of our time.
Most of humus is lost as a result of severe erosion and weathering. In addition, the cultivated lands lose this natural fertilizer due to its oxidation during the plowing and burning of vegetation in the framework of the slash-and-burn agriculture system. The constant loss of humus is also observed when nitrogen reserves are depleted in the soil. In developed countries, nitrogen depletion is compensated by using mineral nitrogen fertilizers and cultivation of leguminous crops.
Excessive grazing in tundra, forests, and especially in meadows leads to the destruction of the land and the development of diseases, and the world is threatened by the extinction of rare species. The question of the extent to which the world is threatened by overgrazing is very topical now.
Drainage leads to the oxidation of organic substances accumulated in peat bogs. This also leds to greenhouse effect and may be mentioned in your global climate change essay outline. When removing the 1-meter layer of marsh water from 1-hectare area, dozens of tons of dissolved organic matter is released.
Irrigation of Lands
In some cases, this practice causes losses of crucial elements of soil as a result of irrigation erosion. At the same time, the correct melioration of poor desert areas increases the resources of organic matter in the soil. This is one of the most actively discussed environmental science research paper topics. Today, 0.2-0.3 million hectares of irrigated lands are annually turned into wastelands due to salinization and waterlogging. After that, they become completely damaged, uninhabitable, and unfit for agricultural use.
Construction and growth of cities, the creation of communications, and mining generally lead to massive destruction of the soil and vegetation cover; sometimes, in order to partially lessen the damage, parks are created on the areas that have been subjected to human influence. Every year, construction works and mining operations destroy the soil and vegetation cover on an area of 5-10 million hectares that leads to a decrease in the organic matter stocks of the biosphere. Even the most approximate calculation will give the total figure of annual losses equal to several hundred million tons of organic matter.
Possible Consequences: Points to discuss in argumentative global warming essay
There would not be so many global warming essay examples if humanity was not afraid of the possible consequences of this phenomenon. If current tendencies remain unchanged, the carbon dioxide content in the atmosphere will double by 2060 (compared to the pre-industrial level) and quadruple by the end of the century. This is an extremely disturbing fact because the life cycle of CO2-emissions in the atmosphere is more than a hundred years. For comparison, water vapor has an eight-day cycle.
Modern predictions are based on the idea of a dynamic equilibrium among all components of the natural environment and the danger of its breaking. In particular, anthropogenic warming of the climate system as well as the decrease (or even disappearance) in the mass of sea and ocean water bodies, the release of CO2 by the atmosphere, the reaction of organic substances accumulated in the atmosphere, etc. In the next century, according to the researchers of the IPCC, there will be a rapid transition from the industrial to the postindustrial level.
In such conditions, the life of the atmospheric surface layers will be disrupted for several times. All this can be described in your climate change research paper outline.
At the beginning of the life cycle, the main way of providing the living space for the CO2-emissions is to release organic substances accumulated in the environment.
