Like its flora, India is also rich in its fauna. It has approximately 90,000 animal species. The country has about 2,000 species of birds. They constitute 13% of the world’s total. There are 2,546 species of fish, which account for nearly 12% of the world’s stock. It also shares between 5 and 8 percent of the world’s amphibians, reptiles and mammals.

Detailed Explanation

India is home to a vast array of animal life, boasting about 90,000 species. This includes a significant bird population, representing 13% of global bird species. Fish are also plentiful, with 2,546 species that make up almost 12% of the world's fish. Additionally, India contributes to 5-8% of the world's total amphibians, reptiles, and mammals. This biodiversity reflects India's varied ecosystems and climates, making it a unique habitat for many species.

Examples & Analogies

Think of India as a treasure chest filled with different kinds of jewels, each representing a unique species. Just as each jewel is special and valuable, each species plays a role in the ecological balance and contributes to the country's natural heritage.

Medicinal Plants of India

India is known for its herbs and spices from ancient times. Some 2,000 plants have been described in Ayurveda and at least 500 are in regular use. The World Conservation Union’s Red List has named 352 medicinal plants of which 52 are critically threatened and 49 endangered.

Detailed Explanation

India's rich tradition of herbal medicine is evident in its use of approximately 2,000 plants as described in Ayurveda, with about 500 being commonly used today. However, many of these plants are under threat. The World Conservation Union’s Red List highlights that 352 medicinal plants are endangered, indicating a need for conservation efforts to protect these vital resources.

Examples & Analogies

Imagine going to a doctor who prescribes a mix of natural herbs instead of chemical medications. In India, many people still rely on these traditional methods for healing. But just like a garden can be damaged by pollution or neglect, our medicinal plants are at risk due to environmental changes, and protecting them is crucial for both health and culture.

Habitat of India's Wildlife

The elephants are the most majestic animals among the mammals. They are found in the hot wet forests of Assam, Karnataka and Kerala. One-horned rhinoceroses are the other animals, which live in swampy and marshy lands of Assam and West Bengal.

Detailed Explanation

India's wildlife includes majestic elephants that thrive in the warm, humid forests of states like Assam, Karnataka, and Kerala. The one-horned rhinoceros is another notable species, primarily inhabiting the marshy and swampy areas of Assam and West Bengal. These habitats are crucial for the survival of these animals, providing them with food, shelter, and breeding grounds.

Examples & Analogies

Picture a family of elephants playing in a pond under a leafy tree. Their home not only offers a playground but also keeps them safe from predators while providing access to food and water. Just like this family needs a healthy environment to thrive, protecting their natural habitat is essential for their continued existence.

Conservation Efforts in India

Wildlife Protection Act was implemented in 1972 in India. India is the only country in the world that has both tigers and lions. The natural habitat of the Indian lion is the Gir forest in Gujarat. Tigers are found in the forests of Madhya Pradesh, the Sundarbans of West Bengal and the Himalayan region.

Detailed Explanation

The Wildlife Protection Act of 1972 was a significant legislative effort to conserve India's diverse wildlife. Notably, India is unique in that it sustains populations of both tigers and lions within its borders. The Gir Forest in Gujarat serves as a sanctuary for the Indian lion, while tigers are predominantly found across various regions, including Madhya Pradesh, the Sundarbans, and the Himalayas, highlighting the dedication to conservation efforts.

Examples & Analogies

Imagine a big family dinner where everyone is invited, but only some get the most attention. The lions and tigers in India are those special guests—each needing their space and resources to thrive. Just as a family must work together to keep everyone healthy and happy, India must invest in conservation efforts to protect its iconic wildlife and ensure their survival.

Threats to Wildlife and Biodiversity

The main causes for this major threat to nature are hunting by greedy hunters for commercial purposes. Pollution due to chemical and industrial waste, acid deposits, introduction of alien species and reckless cutting of the forests to bring land under cultivation and habitation, are also responsible for the imbalance.

Detailed Explanation

The threats to India's wildlife are varied and serious. Hunting for profit, pollution from industries, the introduction of non-native species, and deforestation for agriculture pose immense challenges to biodiversity. Each of these factors disrupts ecosystems, leading to a decline in wildlife populations and biodiversity loss, which ultimately affects human life as well.

Examples & Analogies

Think of a beautiful pond that supports frogs, fish, and plants. If someone starts adding trash and taking out too much water, the pond can no longer support the life that depends on it. Our environment works the same way: when we exploit resources and harm ecosystems, we jeopardize the survival of countless species, including our own.

Government Initiatives for Conservation

To protect the flora and fauna of the country, the government has taken many steps. Eighteen biosphere reserves have been set up in the country to protect flora and fauna. Twelve out of these, the Sundarbans, Nanda Devi, the Gulf of Mannar, the Nilgiri, Nokrek, Great Nicobar, Simlipal, Pachmarhi, Achanakmar-Amarkantak, Agasthyamalai, Kangchendzonga and Panna have been included in the world network of biosphere reserves.

Detailed Explanation

In response to the threats facing wildlife, the Indian government has established eighteen biosphere reserves aimed at conserving various ecosystems and their inhabitants. Notably, twelve of these reserves, including Sundarbans and Nanda Devi, are recognized internationally as important habitats that require protection due to their biodiversity and unique ecological characteristics.

Examples & Analogies

Think of these biosphere reserves as safe havens or sanctuaries where endangered species can live without fear of hunting or habitat destruction. Just like a superhero protects a city from danger, these reserves shield fragile ecosystems and the plants and animals that call them home, ensuring they can flourish.
