Greenhouse Effect And Ecosystem
Environment plays an important role in human life. Nowadays, people are trying to take care of this environment, to ensure the prosperity and happiness of their life . Environment or ecosystem is the interaction and interface between living things (biotic) and non-living (a biotic) in nature. Biotic component includes all kinds of living creatures such as humans, animals, plants and micro organisms. Whereas a biotic components include non-living components such as soil, water, wind, air, sunlight and so on. Living in the globalization world, the rapid increase of human population, led to increased variety of environmental problems. Activities that have been carried out such as industrial and logging was threatening environment badly. Human activities now rely on scientific and technological progress and economic development which has become concerned as the major cause of pollution. The continuous contamination of the environment could give bad consequences to the dynamic of the ecosystem. The greenhouse effect is one of the phenomenon that turns our earth's temperature rose higher and hotter. This means that the ultraviolet radiation emitted by the sun to the earth, partly reflected into space while the rest is reflected into the earth to make it hotter. The heat which reach the earth is reflected back by the earth's surface into space as infrared rays. Thermal energy is not necessarily impenetrable as most heat out of the atmosphere will be absorbed by gases which trapped in the atmosphere such as carbon dioxide, carbon monoxide, chlorofluorocarbons and methane. This trapped heat will raise the temperature of the earth's surface and make sure that the earth is always hot. Increase amount of contaminated gases such as nitrogen oxide and sulfur dioxide also contributes in the rise of the earth surface temperature. The increase in carbon dioxide caused by the burning of fossil fuels such as coal, petroleum and natural gas. Greenhouse effect has a great impact on ecosystem as it negatively affects marine life, a biotic components, causes migration of certain species and leads to vegetation change in forests.
First of all, greenhouse effect has brought many harmful effects to marine life. The phenomenon begins with ocean acidification which leads to the death of some species of sea lives. There is always a constant exchange between the upper layers of the oceans and the atmosphere. The equilibrium is maintained and means the ocean and the atmosphere contains equal concentrations of carbon dioxide. However, when greenhouse effect occurs, this means that there will be more carbon dioxide remaining in the atmosphere as it is the main contributing factor. The carbon dioxide will not only dissolves in atmosphere but also dissolves in the surface waters of the oceans. The dissolve of carbon dioxide gases in the ocean will generate dramatic changes in sea water chemistry. The chemistry alters first when the carbon dioxide gases (CO2) reacts with water molecules (H2O) and forms the weak acid H2CO3 (carbonic acid). Most of this acid then dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3-). There are now more dissociated hydrogen ions which are acidic in the sea. Therefore, the sea has become more acidic which means a decrease in pH value of the sea. Ocean acidification is causing harmful effects to the marine life. Increased acidity reduces carbonate which is the mineral used to form the shells and skeletons of many shellfish and corals. The effect is just similar to osteoporosis, slowing growth and making shells weaker (Natural Resources Defense Council). If pH levels drop enough, the shells will literally dissolve. Some sensitive species could lose their protective shells and eventually die out. According to Jennifer Kennedy, fish and other marine life are also affected by compromising their ability to reproduce because of the process of acidosis, or buildup of carbonic acid in...
