AlsoThese amazing forests covered 1.77 billion hectares or 6.8 million square miles of land which is at least 8 per cent of Earth’s land surface yet they contain more than 50 per cent of diverse species of all plants & animals of all around the world. Tropical Rainforests have been called the ” Lungs of the Earth “. The reason behind is that it cleanses about ten per cent of greenhouse gases produced from human-caused activities. These Anthropogenic activities are destroying very much the existence of Rainforests and the ecosystems depended upon them.
Rainforests – Crucial for Earth Environment
Tropical forest trees, like all green plants, take in carbon dioxide and release oxygen during photosynthesis. Forests are a stabilized natures’ fighting force for the climate. They regulate ecosystems, protect biodiversity. And play an integral part in the carbon cycle, support livelihoods. This impacts the supply of goods and services that can drive sustainable growth. Approximately 2.6 billion tons of carbon dioxide, one-third of the CO2 released from burning fossil fuels, is absorbed by forests every year. They have other climatic effects like; cloud formation by recycling water vapour. Carbon dioxide (CO2) is the most prevalent greenhouse gas. CO2 accounts for about 82.2 per cent of all U.S. greenhouse gas, according to the Environmental Protection Agency (EPA). Studies say about 300 billion tons of carbon; which is 40 times the annual greenhouse gas emissions from fossil fuels, is stored in trees.
Rainforests – How we are Causing Damage
Rain-forests are going under heavy legal and illegal logging for their precious agricultural uses via slashing, burning (a recent case of Amazon rain-forest fire) & clear-cutting throughout the 20th century and hence the size of the rain-forests has been shrinking thought out the world. Reports form may Govt. & Non- Govt. bodies have declared that large numbers of species are on the verge of extinction, approx. more than 50,000 a year. At that rate, a quarter or more of all species on Earth could be exterminated within 50 years; if keep removing habitat environment by destroying the rain-forests. Expansion of urban areas is another factor causing the loss of rain-forest. Deforestation is the second largest anthropological source of carbon dioxide to the atmosphere (after fossil fuel combustion). The quantum ranging between 6 per cent and 17 per cent, according to a study published in 2009 in Nature.
Destruction of Rainforests at this rate is causing adverse affects to Earth Environment as well as Human health (more polluting gases causing lungs diseases).
Dangers of Rainforests Extinction
Deforestation is one of the major factors which have been conducting a significant role in global climate change. This makes an impact on the global carbon cycle. The forest converts carbon dioxide into oxygen during its photosynthesis process plays a significant role in balancing the global temperature. Because the even lesser quantity of CO2 into earth’s atmosphere (with compare to Oxygen) on a global scale holds a large amount of heat (thermal radiation) from the heat energy received from the sun. This property of carbon dioxide makes him the active agent in an increase in global temperature. Deforestation results not only in the lesser amount of oxygen production but it also releases the stored CO2 into them when the tree dies. Forest Resources Assessment report shows has proven that billions of tons of Carbon relapsed into the atmosphere due to deforestation.
Rainforests – Not Just Lungs of Earth But Ours, too !
Apart from Carbon dioxide, As a result of deforestation of Rainforests is causing water vaporization; which also acts as a greenhouse gas. Deforestation affects the exchange of CO2 & water vapour into the atmosphere and terrestrial land surface, Changes in their atmospheric concentration affect negatively on climate. The amount of carbon dioxide added to the atmosphere every year due to deforestation is about more than 5 billion tons.
We should not only focus on stopping deforestation but also collectively work on reforestation. Moreover making our daily habits a more sensible use of products made of trees can save numerous amount of trees. And this will help to save the forest. Vertical Forest is one of the effective ideas as a replacement of typical forests. Also, Developing cities occupying more and more space of the land must look forward to solutions like this.
