An important ecosystem service provided by forests is the ability to counter-act the effects of global warming. Carbon dioxide, a contributing factor to global warming, is taken up by the plants and vegetation contained in forests through photosynthesis and the resulting carbon is stored in both living and dead plant biomass. This process, known as carbon sequestration, greatly reduces the potential for global climate change (IPCC 2001). Forest cover also affects the albedo, that is, the proportion of incident solar radiation that is reflected by the earths surface. The dense green coloured canopy of tropical forests have a low albedo when compared with grasslands or deforested areas. This allows for more incident solar radiation to be absorbed and cooler air termperatures (O’Brien 1996).
Perhaps the most important ecosystem service provided by forests, which is a basic requirement for life, is the supply of clean water. Forests facilitate the storage of clean water through filtering precipitation through the tree canopy. This, in effect, slows the rate at which precipitation collects at the ground surface allowing it to remain unsaturated. It is estimated that over 2/3 of the clean water supply is United States is contained within stream water, which was filtered through forests, with a direct value exceeding $27 billion per year (Snail 2009). This clean water can be captured and stored in watersheds that in turn, can be used for variety of purposes including agriculture, municipal drinking water, recreational activities and habitat for wildlife.
Global forests provide habitat for wildlife, which in turn, contribute to the maintenance of ecological processes. Wildlife is directly utilized by humans for hunting, observation and ecotourism. However wildlife is considered an important ecosystem service because of its indirect contribution to many other ecological processes. Wildlife plays an important role in the pollination and seed dispersal of crops. Eighty percent of the world 1,330 cultivated crop species are pollinated by wild pollinators who typically live in forested regions (Abroamorvitz 1997). Additionally wildlife plays an important role in biologically controlling pest populations, specifically in timber species (Snail 2009).

Nowadays, earth has been facing a series of severe environmental issues which require urgent attention to make the ecology friendly, and global warming is considered as the most vital one. Although some people doubt and disagree that global warming is happening, climate change is real and it is mainly influenced by human activities through the increased production of green house gases such as methane and carbon dioxide. Global warming has the effect of melting polar ice caps and glaciers, which will lead to sea level to go up. Moreover, due to the rise of sea level, the survival of those people who live in islands and coastal cities can ultimately be threatened. Deforestation has been considered to be one of the most important contributing factors to global climate change. Also, since trees absorb greenhouse gases, reduce carbon emissions, and produce oxygen, without trees, the greenhouse effect can be improved tremendously. As World Resources Institute has pointed out in the data, forest loss contributes between 12 percent and 17 percent of annual global greenhouse gas emissions. Thus, what is “deforestation”? Why do people have to deforest? How does it affect environment?
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. (EPA Environmental Protection Agency, 2014)
According to the Urban Forestry Network, trees improve our air quality, and reduce energy costs. The heat from the earth is within the surface and atmosphere due to high levels of carbon dioxide with other heating gases. It prohibits the heat from entering the space. "Therefore, trees help by removing (sequestering) CO2 from the atmosphere during photosynthesis to form carbohydrates that are used in plant structure/function and return oxygen
Everyone needs to respire in order to live, which includes plants and animals. Trees and plants help to regulate the carbon cycle. When the trees take in the carbon dioxide from the environment, they give back to oxygen. When trees are cut down, there is a break in the carbon cycle, and there is no exchange in both oxygen and carbon dioxide which causes a spike in carbon dioxide levels. When these occur carbon dioxide moves in the atmosphere and stores there as a greenhouse gas. “However, deforestation still remains the second leading cause of greenhouse gas emissions, just behind industrial emissions” (Culas). Greenhouse gases disturb the normal regulation of the weather. When greenhouse captures and stores heat problems occur. When the carbon dioxide levels in the greenhouse gases are increased, then the atmospheric conditions becomes unstable, which causes global warming. Global warming is the increase in the temperature of the earth, which is mostly caused by the greenhouse effects. Global warming present itself by affecting the environment by causing drought, floods, change in ecosystem, less fresh water available and other environmental issues. Trees play a big role not only in keeping the soil rich, regulating the water table, providing a stable anchor for soil to lessen soil erosion and providing nutrient rich soil for agriculture but it also helps in the absorption of carbon emission in the atmosphere.
The world’s climate is kept stable and suitable to live in, mainly by rainforests, in a number of ways. They are often known as ‘climate controllers’. They keep the planet cool, as they absorb much of the suns heat, instead of reflecting it back into the atmosphere.
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
The forests around the world a supply a plethora of community amenities and commercial goods , nevertheless forested terrain progressively is becoming transformed to accommodate other uses, including cropland, pasture, mining, and urban areas, which can produce superior private financial returns. The wide array of benefits the forest provides that vanish directly tied to deforestation have resulted in several policies drafted with the sole intention to reduce the frequency of deforestation. This paper has two primary objectives. First, this paper will review and summarize both the preceding and current research on deforestation. Second, it will emphasize the significance of future research and development, as well as other solutions needed
The relationships between plants and pollinators play a key role in our ecosystems. Pollinators are animals, such as bees, butterflies, moths, bats, flies, wasps, and birds, that transfer pollen from one flower to another. Pollination is the movement of pollen to the male or female part of the plant. This leads to fertilization and the production of seeds and flowers. They maintain and establish ecosystems. “Pollinators are an integral part of our environment and our agricultural systems; they are important in 35% of global crop production” (NCRS 2013). “Pollinator declines can result in loss of pollination services which have important negative ecological and economic impacts that could significantly affect the maintenance of wild plant diversity,

But they can become carbon sources when they are cut or burned. Tropical forests hold more than 210 gigatons of carbon and deforestation represents around 15% of greenhouse gas emissions. These GHG emissions lead to rise in temperatures, weather changes, water changes and increase the chance of extreme weather events. In Sumatra, for example rainforests on deep peat lands are being cleared and converted to plantations, leading to the high GHG emissions in Indonesia. These climate changes can affect forest creatures due to loss of food and water, while some can adapt species losses can occur
Climate change is evidenced through shifts in the weather patterns such as winds, humidity and temperatures over certain durations. Natural climate changes occur less frequently and they are triggered by factors related geographical aspects as well as solar radiation. The earth’s movement on the orbit triggers changes in climate causing some areas to have higher temperatures than usual while others are significantly cold depending on the position of the earth on the orbit. The heat form the sun causes changes on the stratospheric ozone and it increases the amount of greenhouse gases. Heat from the oceanic crust also contributes to warming as a result of episodic hydrothermal venting (Liao & Sandeberg, 2012). Volcanic activity also causes a release of certain elements that may block the sun and also contribute to increase greenhouse gases in the atmosphere.
all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
Global warming is one of the most serious issues that the human species face today, yet the majority of the population does not pay attention to it. People are not aware of the dangers and do not care about it much because the main effects will affect the next generation and not themselves. Global warming is happening and it is the reason for changing weather and weather extremes such as earthquakes, floods and wildfires. Global warming is caused by societies lifestyle and these lifestyles destroy the environment and affect the whole world. The use of cars, trains, planes, as well as wasting energy for people’s entertainment has a price; this price is that society is in danger.
