How Many Species Are There On Earth And How Many In India?

Biodiversity refers to the variety of life on earth, including the different species of plants and animals, the ecosystems they inhabit, and the genetic variation within each species. Biodiversity plays a critical role in maintaining the balance of our planet’s ecosystem and the survival of life on earth. However, due to human activities such as deforestation, pollution, climate change, and over-exploitation of natural resources, biodiversity is under threat. 

Conservation of biodiversity aims to protect and preserve the different species and ecosystems and maintain the balance of the planet’s ecosystem. Conservation of biodiversity can be achieved through various methods such as habitat protection, species protection, and ecosystem management. It is important for humans to understand the significance of biodiversity and take necessary steps to conserve it for future generations.

 How Many Species Are There On Earth And How Many In India?

Biodiversity refers to the variety of life on Earth, including the variety of species, ecosystems, and genes. It is a crucial aspect of life on our planet, as it provides us with important ecosystem services, such as food, medicine, and natural resources.

According to the International Union for Conservation of Nature (IUCN), there are approximately 8.7 million species on Earth, but only 1.2 million of these species have been scientifically described and catalogued. Of these 1.2 million described species, around 41,000 are considered threatened with extinction. The remaining 7.2 million species are still undiscovered and waiting to be discovered. In India, the estimated number of species is around 90,000, with around 50,000 species of plants and around 20,000 species of animals. The remaining species include fungi, bacteria, and microorganisms.

However, despite India’s rich biodiversity, many species are facing threats due to habitat loss, over-exploitation, climate change, and other human activities. For example, over one-third of India’s mammal species are considered to be at risk of extinction, including the Bengal tiger, Asian elephant, and one-horned rhinoceros.

To protect and conserve biodiversity, it is essential to understand the value and importance of biodiversity and take concrete steps to preserve it. This includes establishing protected areas, promoting sustainable use of natural resources, and reducing the threats to biodiversity, such as climate change and habitat destruction.

In conclusion, Earth’s biodiversity is a valuable resource that provides us with numerous benefits. However, it is under threat from various human activities, and it is up to us to ensure that future generations can enjoy its benefits. By protecting biodiversity, we can also preserve the ecosystem services that support human life, making the world a better place for all.

When it comes to the classification of species, the following is the estimated number of species in different groups:
