India is home to approximately 47,000 species of plants. Can anyone tell me where that places us on a global scale?
Tenth place in the world?
Exactly! And we are fourth in Asia. This vibrant flora includes 15,000 flowering plants. That’s about 6% of the world’s total flowering plants!
What about non-flowering plants?
Good question! Non-flowering plants like ferns, algae, and fungi also contribute to our biodiversity.
Let's remember this information with the mnemonic 'FINE BAGS' - Flora Includes Non-flowering, Evergreen, and Beautiful Amazing Green Species.
What do you mean by endemic species?
Endemic species are those that are native and restricted to a certain geographic area. Let's explore more types of vegetation!

India hosts several types of forests. Can anyone name one type?
Tropical Evergreen Forests?
Correct! They exist in high rainfall areas and are known for their tall trees. Now, what about the rainfall these forests need?
More than 200 cm?
Exactly! And these forests are home to diverse wildlife, such as elephants and rhinoceroses. Let’s use 'Tall Trees Shelter Many Species' as a memory aid.
What about dry deciduous forests?
These forests shed their leaves during dry seasons and are found mostly in eastern India. They come in moist and dry varieties based on the rainfall levels.
And what animals can we find there?
Common animals here are lions, tigers, and deer. Let’s remember them with the acronym 'LTD' - Lions, Tigers, and Deer.

Why do you think conserving wildlife is essential?
To maintain the ecosystem balance!
Precisely! Each species has a unique role, and the loss of any can disrupt the entire ecosystem. Let’s learn about the Wildlife Protection Act of 1972.
What kind of protections does it offer?
It establishes national parks, wildlife sanctuaries, and biosphere reserves to protect various species and habitats.
Are there any projects related to wildlife?
Yes, for example, Project Tiger and Project Rhino. Let's create a rhyme: ‘Project Tiger, Project Rhino, Protect our wildlife, let them grow!’
What else do we need to do for conservation?
We need to spread awareness about endangered species and support conservation efforts by reducing pollution and habitat destruction.

Chapter Content
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.
