Are you sweating in hot summer? This is a normal phenomenon where our body release water in form of sweat to maintain our body temperature. The similar phenomenon happened with plants with a process known as Transpiration.

Transpiration

is a process in which plants losses water from areolar parts, particularly by

leaves through stomata. This is a continuous process as when atmospheric

temperature gets increased due to sun light, plant start sweating/transpiring

thereby Colling themselves and air as well. In forest areas the large volume of

water came into atmosphere due to transpiration that induce cloud cover to near

by area and thus may trigger rainfall. Hence increasing the trees plantation

and forest coverage can help in reducing the impact of global warming by

increasing transpiration. This is precisely the reason why scientist raises

concern for decreasing plants and deforestation. Fortunately, tree and forest

coverage has increasing trend in India in past years despite increasing

infrastructure projects.

Plants may

play a vital role in maintaining the global climate in future. Increasing human

population and greenhouse gases will increase the global temperature in coming

days. This is because the contribution of CO2 and other GHG will continue to

rise and thus increase the global temperature.

How

increasing Trees/forest can help in balancing global temperature;

Sun is the

ultimate sources of energy on earth. Plants traps considerably good amount of

sunlight as a source of energy to produce glucose. This is done in a process

called Photosynthesis where plants produce glucose from carbon dioxide and

water using sunlight as a source of energy. Here it is to be noted that, root

absorb water from ground and send the same till leaves by a process known as

imbibition. Whereas leaves collect atmospheric carbon dioxide through stomoata

and sunlight through chloroplast. Water, carbon dioxide and sunlight used as an

input for photosynthesis.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy

from light produces glucose and oxygen

Photosynthesis

is comprised of two stages, the light-dependent reaction and the

light-independent reactions. The light-dependent reaction uses energy captured

from sunlight by the chloroplasts in plant leaves. to produce a supply of

electrons for the light-independent reactions. The light-independent reactions

use energy from the supply of electrons to reduce carbon dioxide to produce

glucose.

The resulting

glucose is converted to adenosine triphosphate (ATP) through cellular

respiration, to provide energy. In addition to glucose, this reaction produces

oxygen that is released by the plants into the atmosphere.

What plants has done:

  1. Here plants first absorb the atmospheric CO2 thus reducing the one of the causes of global warming
  2. Releases water through transpiration and photosynthesis, thus contributed in cooling effect of already warm environment, induce the cloud and trigger rainfall
  3. Releases oxygen which comprises of 20-28% of atmospheric oxygen
  4. The above all three factors creates a suitable and healthy atmosphere for sustainable development by reducing adverse impact of GHGs
