What is Biodiversity?

Biodiversity is the foundation of life on Earth. It is crucial for the functioning of ecosystems which provide us with products and services without which we couldn’t live. Oxygen, food, fresh water, fertile soil, medicines, shelter, protection from storms and floods, stable climate and recreation - all have their source in nature and healthy ecosystems. But biodiversity gives us much more than this. We depend on it for our security and health; it strongly affects our social relations and gives us freedom and choice.

Biodiversity is extremely complex, dynamic and varied like no other feature of the Earth. Its innumerable plants, animals and microbes physically and chemically unite the atmosphere (the mixture of gases around the Earth), geosphere (the solid part of the Earth), and hydrosphere (the Earth's water, ice and water vapour) into one environmental system which makes it possible for millions of species, including people, to exist.

At the same time, no other feature of the Earth has been so dramatically influenced by man’s activities. By changing biodiversity, we strongly affect human well-being and the well-being of every other living creature.

 Why should we protect the Earth's
Biodiversity ?

Most of us believe that all life has a right to exist. But speaking more selfishly for humans, biodiversity is the foundation on which human life depends. Plants and animals provide food and medicine, rivers provide precious drinking water, and trees absorb greenhouse gases and clean the air we breathe. In addition, ecosystems such as forests and wetlands play a huge role in preventing floods and landslides. The world's poorest rely most on ecosystems for their daily needs, and will be worst affected by biodiversity loss.

The importance of biodiversity :

1. Source of medicine and herbs

Many plants are rich sources of modern and traditional medicines

2. Source of genetic diversity


Enhance the richness of gene pools to further increase diversity in future generation

3. Source of raw materials


Trees and plants enable paper, timber, textile and paper industries to grow

4. Source of food


Plant and animal diversity provide variety of food

5. Maintain the water cycle

Wetlands and forests provode clean water through repeated filtrations

6. Maintaining the fresh air cycle

Plants and trees take in carbon dioxide from the atmosphere and release oxygen during photosynthesis
