When deforestation is committed, the green cover which helps in balancing the atmosphere is reduced and it leads to natural disasters such as global warming, flash floods and green house effect. The animal kingdom is also suffered as the habitat destruction caused by land clearing in such a way that their natural habitat is lost for human’s benefits. Animals are being forced to move further away and adapt new regions or die
The pollutants that discharge directly or indirectly into water bodies without sufficient treatment to remove harmful mixtures are called water pollution ("Environmental pollution," n.d.). The lives of animals are disturbed by human activities that contaminate the soil. Environmental contamination kills the fish and insects, which leads them to extinction. To explain, Pesticides are a source of pollution, agriculturalists use pesticides to prevent insects from eating crops. Pesticides stay in harvests, wild plants eaten by herbivores, and insects.
However, fossil fuels such as coal and oil contributes detrimental air pollution. According to a study, the use of fossil fuels contributes approximately 1.8 million air-pollution related death globally. Therefore, scientist came up with the idea of nuclear energy. Nuclear energy can decrease the air pollution by reducing the emission of greenhouse gases that will contribute to global warming. Nuclear fission and nuclear fusion are the important steps to produce nuclear energy.
The major sources of SO2 and NOX in the atmosphere are: Burning of fossil fuels to generate electricity, Two thirds of SO2 and one fourth of NOX in the atmosphere come from electric power generators, Vehicles and heavy equipment, and finally manufacturing, oil refineries and other industries. Winds can blow SO2 and NOX over long distances and across borders making acid rain a problem for everyone and not just those who live close to these sources. As acid rain has these causes, it also has effects. Acid rain has many ecological effects, but none is greater than its impact on lakes, streams, wetlands, and other aquatic environments. Acid rain makes waters acidic and causes them to absorb the aluminum that makes its way from soil into lakes and streams.
The mode of action of lantana toxin appears to be by inhibiting the active secretion of bile canaliculi in liver and result secondary photosensitization in all grazing animals (Csurhes and Edwards, 1998). Due to its strong allopathic properties, aggressiveness and its dense impenetrable thorny thickets, Lantana camara has the potential to interrupt the health and regeneration process of other species by decreasing germination, growth of seedlings and biomass production which in turn increases mortality and decline of plant species, pasture and crops (Gentle and Duggin, 1998; Catherine and Russell, 2005; Sharma et al., 2005; Sharma and Raghubanshi, 2006). Lantana camara was introduced to Ethiopia as an ornamental plant due to its beautiful aromatic flowers (Binggeli and Desalegn, 2002). However, because of prolific seed production and easy dispersal, it escaped cultivation and become a pest in the social, ecological and economic concerns. Presently, it has spread almost all over the country, but still it is not much perceived as a chronic environmental problem, except in few parts of Ethiopia, such as Oromia and Somali regions (Binggeli and Desalegn,
This also has the potential to block migration and mating patterns, which would lead to a decrease in the population of certain species (“Various Disadvantages of Hydropower,” conserve-energy-future.com). It also presents various construction challenges such as: the initial production costs, the amount of space required, and requiring only construction materials of the finest quality. Dam breakage could result in massive floods, which would hurt animals and people alike. It has also been shown that small run-off plants produce between .01 and .03 pounds of carbon dioxide per kilowatt hour (“Environmental Impacts of,” ucsusa.com). Despite all of these drawbacks, with careful consideration in planning and precise execution, many of these possibilities can, potentially, be avoided.
The biggest cause of acid rain is the burning and combustion of fossil fuels by factories, power plants, and automobiles. The U.S. Environmental Protection Agency (EPA) records in "Clearinghouse for Inventories and Emissions Factors” that roughly 70% of SO2 releases formed in 2006 were caused by fuel combustion via fossil-fueled electrical utilities. Highway automobiles were the chief source of NOx releases, responsible for 36% of the total amount of emissions in 2006.
Air pollution is the root cause of acid rain, and with power plants releasing massive amounts of sulfur dioxide and nitrogen oxides when fossil fuels are burned, we are adding more flame to the effects of acid rain. According to (http://www.world-nuclear.org/information-library/country-profiles/countries-a-f/china-nuclear-power.aspx) China has 38 nuclear power reactors in operaion, about 20 under construction, and more about to start construction. China’s electricity is mostly produced from
Due to the greenhouse effects coal burning produces, big consumers of coal like China and India will be forced to decrease their coal consumption. Such a dramatic change in the market will affect the efficiency of the supply chain in such countries, because of the great amounts of coal it is used to transport. Less demand will require less instruments in the maritime logistic chain like for example less vessels, less conveyors, smaller terminals, among others. 3.2 Technology
emissions of CO2 from coal burning accounts for the additional 65% carbon dioxide in the atmosphere, increasing greenhouse gases. To anyone 's books this means climate change and global warming. The pollution it causes has also led to acid rain in some areas. Although there are a lot of causes of acid rain, burning coal is a major contributor because it releases sulfur dioxide, and acid rain has higher than normal amounts of sulfuric and nitric acid. Newer coal plants, however, now emits 40% less CO2, according to the World Coal Institute.
