Threats to Biodiversity

The biodiversity of our planet is encompasses millions of animal and plant species. In fact, it will not be wrong to say that biodiversity includes all life forms, along with microorganisms, that live on the planet. However, today, due to human activities and natural elements, the biodiversity is under threat.

Here are the threats to biodiversity that have an adverse follow on the very existence of the different plants and animals:

Loss of habitat: This is occurring due to humans. As human people is growing, we need more and more space to adapt this every expanding number. Hence, forests are being cut down to make space. This is important to habitat loss wherein wild animals and plants no longer have a place to live and survive.

Threats to Biodiversity

Over hunting: This is another human action that has endangered many species of animals. Some of them are on the verge of extinction. From time immemorial humans have been hunting animals for food, ornaments and clothes. However, in contemporary time, poaching and indiscriminate hunting of animals has brought many animal species to near extinction.

Invasive species: At times species of plants and animals that are not native to a place have invaded the region resulting in extinction of the endemic species. When a new species of plant or animal is introduced into a region, it will compete with the native species for food. As the native species do not have the required defense or adaptation against the new species, they succumb. Many of the invasive species have been introduced by humans, like introducing the Nile perch into Lake Victoria which cause the extinction of the Cichlids living in the lake.

Pollution: This is another man-made threat to the biodiversity on the planet. Due to pollution of air, water and soil, any species of plants and animals are facing threat of extinction. This is especially true for species that live within a small geographical area. For example, the Chinese river dolphin became extinct due to pollution of its geographical area, the Yangtze River, after it got polluted due to industrialization.
