Help the Environment

How do plants help the environment?

1. Maintains Climatic Conditions

Plants suck in carbon dioxide and release oxygen.

  • Carbon dioxide is a greenhouse gas that contributes to global warming and climatic changes. When plants are cut, carbon dioxide levels go up, and this has a huge impact on the environment.

  • Oxygen is vital to sustain human and animal life through cellular respiration

2. Lowers Air Pollution

The tiny particles that float in the air, especially seen when you live near industries, are bad for your lungs. This is pollution caused by planes, cars, factories, and many more man-made things. The plants that live alongside us prevent us from the harm of pollution, and absorb dangerous pollutants.

3. Prevents Desertification

There is a risk that the fertile parts of the earth are potentially becoming infertile and desert-like.

  • This happens because of poor farming practices and drought.
  • Planting trees helps to combat this issue. The root structures the soil and does not let it dry out and erode.
  • Plants that decompose give the soil essential nutrients, which improves soil quality.
  • Plants also move huge amounts of water from the soil to the atmosphere and aid the biogeochemical cycle
  • They host bacteria in the soil that fix nitrogen which is in turn used by other organisms


  • The importance of plants is usually forgotten, and the ways plants help us are often taken for granted.
  • Plants are the major supplier of food to all terrestrial organisms.
  • They play a pivotal role in maintaining the optimal atmospheric conditions
  • Plants produce oxygen through photosynthesis, without which respiration and thus life would not have been possible.
  • Plants also recycle matter and provide many products for human use.
  • Plants create a natural habitat for most organisms.
  • In a nutshell, life without plants is unimaginable.
