First of all, what is Global warming?

Global warming is the unnatural heating of the Earth’s surface and it’s atmosphere due to the excess emission of CO2 and other Greenhouse gases also known as CO2 equivalents (CO2e), that trap the planet’s heat and prevents it from escaping into the atmosphere.

There are many factors that are playing a major role in increasing global warming in the modern era. The two main reasons being:

  • Large-scale industrialization
  • Rapid deforestation

Let’s talk about deforestation! As the term itself makes it clear, deforestation is the rapid cutting down of trees and removal of forests for obtaining raw material for industries and to accommodate the rising population.

Forests and vegetation are crucial elements that maintain the average atmospheric and surface temperature on earth through transpiration and are also major carbon sinks that maintain the CO2 and Oxygen levels in the atmosphere through photosynthesis.

  • The result of large-scale deforestation means the rapid loss of vegetation.
  • This further implies that average atmospheric and surface temperatures will rise due to lesser transpiration.
  • Furthermore, it will be nearly impossible to keep a check on the rising CO2 levels due to industrialization and widespread use of automobiles as the natural carbon sinks are being removed by cutting down forests.

How can increasing vegetation reduce global warming?

In recent years, mankind has invested a lot of time, money and expertise in developing green energy facilities and promoting green transportation. However, focusing on conserving forest cover and increasing vegetation is also very important.

How can increasing vegetation reduce global warming?

There are 2 major points that we need to understand to know how can increasing vegetation reduce global warming:

  • Transpiration

Plants and trees transpire, which means the moisture that is carried through plants from roots to small pores on the underside of leaves, changes to vapor and is released to the atmosphere. It is essentially the evaporation of water from plant leaves. This leads to cooling of the surrounding air and thus a considerable control on the rising temperatures caused by global warming.

  • Natural Carbon sink

CO2 is the most prominent greenhouse gas. If there is more vegetation, the plants will utilize more of the CO2 that is emitted into the atmosphere from various sources for photosynthesis and release Oxygen in return. Thus, vegetation will act as an effective carbon sink, reducing the CO2 levels and increasing the Oxygen content in the air, ultimately improving the average air quality damaged due to global warming.

It is undeniable that with the advent of advanced technologies there will be growth in industrialization, but mankind can and should also invest more on greener ways to tackle global warming issues. However, only developing green energy facilities and promoting green transportation won’t be enough. Increasing earth’s forest covers and vegetation would also ultimately help tackle global warming issues. It is also more ecologically and economically beneficial to indulge in conserving and multiplying forest cover and vegetation!
