Rainforests are one of the most useful things in this world. They contribute to a lot of the world’s resources and at the moment are being taken advantage of. Based on research done by Rhett butler (Co-founder of Tropical Conservation Science), it shows that by 2013 only 81.4% of the rainforest is left. Whereas in 1970 we still had 97.6% of the world’s rainforest. By 2013, we can see that approximately 763,104 trees have been cut down. Based on the information given, we can say that in 86 years we will only have 49 percent of the rainforest left on this earth. To put this in perspective, 49 percent of trees cut down is equivalent to 1,526,208 trees. Granted that the rate is constant in those 86 years, this is probably the best case scenario. …show more content…
Cutting down trees deprives the forest of portions of its canopy, which blocks the sun’s waves throughout the daytime and holds in heat at night. This disturbance leads to additional life-threatening temperatures swings that can be risky to plants and animals.
Trees also play a serious part in taking in the greenhouse gases that cause global warming. Less woodlands means greater quantities of greenhouse gases entering the atmosphere—and increased speed and brutality of global warming.
From an economic, political and social perspective, the destruction of the rainforests due to the greed of humans have detrimental effects to our earth and safety of the people living on it. Based on the scenarios presented, we can only conclude that the destruction of the rainforest due to human greed will only cause harm to our world.
How do we stop

For the first time we have the possibility to change things. With leadership from the world’s most powerful country. Bernie Sanders has revealed to the world that we must start now and we must see the real threats and we must recognize that mankind is having a major impact on the
A more long term effect would be stunted tree growth because trees need sunlight to grow
2015: A promising year, full of opportunities, though less than 3 months away from coming to a close. Not more than 100 years ago, things were not the same as they exist now. Major problems were faced in eras such as the Progressive Era. Such problems that people faced back then were women’s suffrage, child labor, and deforestation.
The effect of reduced forest size has already had a measurable impact on the composition of our atmosphere in the relatively short amount of time we have been cutting them down(6). Ironically however it is the conversion of forest land to urban and agriculture use that has a more permanent and detrimental impact. Logging and urbanization lead to forest succession. Forest succession happens when there are changes to an environment that causes the composition of plant and animal species to change. New species succeed the existing ones as a result of things like changes in amount of shade, temperature, or the introduction of foreign species.
When this happens it causes adverse effects on the environment. It can be done in a variety of ways from cutting to burning. Either way mass deforestation is bad and needs to stop before it is too late. One culprit of our deforestation is
By cutting down trees, many eco-systems get destroyed and many animals will not survive. I have noticed how this process occurs a lot in Florida. The Florida Everglades once compromised most of the state, and due to human development almost half
Therefore these effects could be substantial. Scientists believe that the destruction of trees is a adding reason to the cause of global warming. Also the IPCC has estimated that if the climate rises 1.5 degrees celsius to 2.5 degrees celsius that 20% to 30% of plants would have high risks of extinction. The same would go for animals if the temperature continue to increase the same percentages of animals could face extinction as well. Now in the last 50 years heat waves, droughts, and flood have all increased.
Deforestation results in the loss of biodiversity Deforestation is having its most devastating effect on biodiversity in tropical rainforests. The destruction of millions of hectares of forests by human activities means: • The removal of the bases of numerous food webs • The loss of habitats for many species of flora and
It has been estimated that tropical rainforests provide 50% of terrestrial species with a habitat (Lovejoy 1997) even though
Global Warming Proposal Introduction The phenomenon of constant increase in the earth’s temperature is known as global warming. The excessive use of fossil fuels is destroying our environment as well as wildlife. It is a great threat to human life too, as this activity is causing intense pollution and also results in damaging the ozone layer.
Do humans cause global warming or is it natural? Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the `earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. What is global warming? Global warming is an increase in the average temperature at Earth's surface (“global warming”).
When large areas of trees are cut down, the earth loses an important source of oxygen. Forests act as carbon sinks that absorb the carbon dioxide that builds up in the atmosphere. Deforestation also affects the microclimate of an area as evaporative cooling is lost. The loss of canopy leads to a decrease in rainfall in the area. This can effect crop production which is essential due to the growing population of the world.
If we continue cutting down forests then soon we will no longer have any forests. It is extremely unfortunate how over 50% of the world forests have been cut down. As a result animals are loosing their habituate and species are going extinct. Not only are animals effected but even humans and the rest of the environment. Rain forests and other forests produce most oxygen that we need.
With deforestation being one of these roles because when we chop down these trees and plants of where animals habitats our it also releases a lot of carbon dioxide into the air. And if you didn’t know forests are major carbon storage centers, when deforestation happens all the carbon dioxide that is stored in these forests; is released back into the atmosphere. Deforestation not only contributes to changes in the climate, it also causes localized changes in the weather. Trees transpire, or release water into the atmosphere, during photosynthesis. This water replenishes clouds and maintains rainfall.
Sustainable forest management requires three major criteria which are the maintenance of ecological processes within the forest (soil formation, energy flow, biogeochemical cycles (carbon, nutrient and hydrological cycles), maintenance of biodiversity of forest, improving the net social benefits derived from the mixture of forest uses within the constraints by considering the future. Forest provides habitats for more than half of the fauna and flora on the Earth (SCBD, 2001). Forest biome plays an important role in mitigating climate change by serving as carbon sinks (Hassan et al., 2005). Forest land is the most fundamental natural resources which become reduced mainly due to anthropogenic pressures. For proper management of land, it is essential to have information about existing land cover and about the naturalness of the land.
According to The REDD desk (2016), the world’s forests are vanishing even though the forests cover a total of 4 billion hectares worldwide which can be represented as 31% of the total land area. It was also recorded that the world lost amount of 8.3 million hectares per year of forest between 1990 and 2000. Although the rate of loss has moderately slowed in the following decade up to 2010, the loss is still excessive with amount of 6.2 million hectares per year. The loss was mainly caused by deforestation and forest degradation that had impacts on biodiversity and forest-dependent communities. Since forest serve as vast carbon sink, the loss of forest coverage led to release of heat-trapping carbon dioxide (CO2) into the atmosphere which is
