Deforestation definitely does more harm than good. It leaves numerous negative effects on the environment and the ecosystem. The main problem caused by deforestation is that it disrupts the carbon cycle, which is linked to climate change and greenhouse effect as well. Tropical deforestation contributes to around 20% of the world’s overall emission of greenhouse gas. Carbon is an example of a greenhouse gas.
There are numerous reasons as to why the rainforests are important to mankind. One of them is that the rainforest actually helps to regulate the climate of the earth. Rainforests which are filled with trees absorb the carbon dioxide present in the air and also produces oxygen. This is especially important with the increasing amounts of anthropogenic carbon dioxide being produced due to human activities. When trees are burned down, carbon dioxide is released and this further contributes to global warming.
Forest fires represent an important source of atmospheric trace gases and aerosol particles. Fire influences global ecosystem patterns and processes, including vegetation distribution and structure, the carbon cycle, and climate. Fires have been observed from the geological scale from the origin of terrestrial life (Bowman et.al. 2009). Spread of fire has been increased in different vegetation types after human’s exposure.
In this paper, we will address the environmental and human health impacts caused by fossil fuel energy and how alternative energy sources can benefit humans and the environment. Classification of fossil fuels The major fossil fuels are crude oil, natural gas and coal. Crude oil (petroleum) and natural gas are obtained from organic materials (mostly plants) that were buried with marine or lake sediments in depositional basins and coal is made up of partially decomposed vegetation buried in sediment that slowly transformed into carbonaceous rock (Botkin & Keller, 2014) The effect of fossil fuels on humans and the environment Burning of fossil fuels has emitted and continues to emit large amounts of carbon dioxide (CO2) into the atmosphere as well as other gases such as methane (CH4), nitrous oxide
A carbon footprint is the total carbon emission from an individual or municipality by their different activities. A carbon footprint can broadly be defined as a measure of the greenhouse gas (GHG) emissions that are directly and indirectly caused by an activity or are accumulated over the life stages of a product or service, expressed in carbon dioxide equivalents ( Wiedmann et al., 2007). A carbon footprint can also be considered as a measure of an individual's contribution to global warming in terms of the amount of greenhouse gases produced by an individual and is measured in units of carbon dioxide equivalent (Lynas et al., 2007). To challenge the problem of global warming and climate change with the interest of reducing green house gas
To determine the difference between the present and absent of vegetation in affecting the carbon sequestration. 1.2 Significance of study The significance of this study is to provide information about the amount of carbon that stored by selected ecosystem. This information is important to identify the type of ecosystem that contribute the most in carbon sequestration. The present of vegetation also help to store more carbon into the soil which also is a best way to mitigate global warming. Factors such as depth, temperature, humidity, type of soil and others need to take in consideration.
It is true that trees are needed for the production of paper; however, the destruction of trees is causing air pollution to get worse. “The removal of trees and other types of vegetation reduce available oxygen, food, shelter, and breeding habitat”. (Deforestation, National Geographic) This proves that trees play a critical role in absorbing greenhouse
Carbon dioxide is naturally present in the atmosphere as part of the Earth 's carbon cycle that is the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals. Human activities are fixing the carbon cycle both by adding more Carbon dioxide to the atmosphere and by affecting the ability of natural sinks, like forests, to remove Carbon dioxide from the atmosphere. While Carbon dioxide transmitted come from a variety of natural sources, mankind-related emissions are liable for the increase that has occurred in the atmosphere since the industrial revolution. Carbon dioxide is continuosly being exchanged among the atmosphere, ocean, and land surface as it is both issued and engaged by numerous microorganisms, plants, and animals. Regardless of how, release and removal of Carbon dioxide by these natural processes usually to balance.
What role does each of the following play in the carbon cycle? • Cars give off large amounts of carbon monoxide and carbon dioxide as a result of burning fuel. Plants use the carbon dioxide during photosynthesis to produce carbohydrates which is necessary for
Trees have a very important role of absorbing carbon dioxide (greenhouse gases) and turning it into oxygen this is part of a process called photosynthesis. If there are fewer trees that means there is more carbon dioxide (Greenhouse gases) that enter the atmosphere. This then causes global warming which is changing the climate all around us. Global warming is also causing the arctic to melt. Which cause the sea level to rise and destroying even more animal
