Rainforests – The lungs of Earth

By

Rain-forest all around the world:

  • This amazing forests covered 1.77 billion hectares or 6.8 million square miles of land which is at least 8 percent of Earth’s land surface yet they contain more than 50 percent of diverse species of all plants & animals of all around the world.
  • Tropical rain-forests have been called the “Lungs of the Earth” because it cleanses about ten percent of greenhouse gases produced from human activities

They imitate crucial part in Earth’s 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, and supply 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 vapor.

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, said from Harvard University, 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.

Dangers of Loss of Rain-forests:

Deforestation; it is considered to be one of the major factor which has played significant role in global climate change. This makes impact on the global carbon cycle.

Forest which makes converts carbon dioxide into oxygen during its photosynthesis process plays significant role in balancing global temperature, because even lesser quantity of CO2  into  earth’s atmosphere (with compare to Oxygen) on a global scale holds 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 increase in global temperature

Carbon dioxide (CO2) is the most prevalent greenhouse gas. CO2 accounts for about 82.2 percent of all U.S. greenhouse gas, according to the Environmental Protection Agency (EPA). About 300 billion tons of carbon, 40 times the annual greenhouse gas emissions from fossil fuels, is stored in trees, according to Greenpeace.

 

The deforestation results not only the lesser amount of oxygen production but it also releases the stored CO2 into them when tree dies. 2010 Global Forest Resources Assessment report shows has proven that billions of tons of Carbon relapsed in to atmosphere due to deforestation

Deforestation is the second largest anthropological (human-caused) source of carbon dioxide to the atmosphere (after fossil fuel combustion), ranging between 6 percent and 17 percent, according to a study published in 2009 in Nature.

Apart from Carbon dioxide, water vapor is also act as green house gas which is affected by deforestation. Deforestation affects exchange of CO2 & water vapor into atmosphere and terrestrial land surface, Changes in their atmospheric concentration affect negatively on climate.

The amount of carbon dioxide added into atmosphere every year due to deforestation is about more that 5 billion ton. We should not only focus on stopping deforestation but also collectively work on a reforestation. Making our day to day habits more sensible use of products made of tree can save numerous amount of tree and help to save forest. Vertical Forest are one of the effective idea as an replacement of typical forests in the developing cities occupying more and more space of the land.
