What is biopersity? Why are forests considered as ‘‘biopersity hot spots’’? List two factors responsible for causing deforestation.
Biodiversity is a combination of biological and diversity. It is the variety and variability of plant and animal life in the surroundings along with their habitat.
Forests are considered as ‘‘biodiversity hot spots’’ because they consist of a huge variety of plant and animal life living together. The communities they form also comes under biodiversity.
Each and every organism has its own importance in biodiversity.
For example, there are many plants and animals that help us in the form of food. Greater diversity would help in the stability of all forms of life.
Some of the causes for the decline of forests are,
- Urbanization
- Industrialization
- Cutting of trees illegally for sandalwood, etc.
There are also some natural causes like forest fires.
Recently forest fires have destroyed huge areas of forests, thus killing many endemic plants and animals.
