Let's understand it simply
Imagine you are swimming in a big river. Now, think about all the things that could harm you: plastic bags, dirty water, big fishing nets, or people trying to catch you. Dolphins and whales live in the sea, but they face these problems every day. Just like you would feel scared or get hurt, these animals also suffer.
How it works
Fishing nets: Dolphins and whales get trapped in nets meant for fish. They can't escape and may drown.
Pollution: Chemicals, oil, and plastic waste go into the sea. These poison the water and the animals.
Hunting: Some people hunt dolphins and whales for meat or oil.
Climate change: The sea is getting warmer. This changes where dolphins and whales can find food.
Boat strikes: Fast boats can hit dolphins and whales, injuring or killing them.
The story behind it
People have hunted whales for hundreds of years for oil and meat. As time passed, new dangers appeared, like plastic pollution and big fishing boats. Scientists started noticing fewer dolphins and whales, so they began to study why these animals were dying. This led to new rules to protect them, but many dangers still remain.
Where you see it in real life
Fishing nets in Kerala or Gujarat: Dolphins get stuck and can't breathe.
Plastic bags in the sea: Whales eat them by mistake, thinking it's food.
Oil spills: Oil from ships covers the water, making it hard for dolphins to breathe and find food.
Whale hunting in some countries: Whales are killed for their meat.
Fast ferries in Goa: Boats can accidentally hit dolphins swimming near the surface.
Climate change: Melting ice in the Arctic makes it hard for some whales to find their food.
Why it matters
Dolphins and whales help keep the ocean healthy by eating fish and other sea creatures.
Many people depend on fishing for their jobs, but if dolphins and whales die, the sea becomes unbalanced.
Tourists come to see dolphins and whales, which brings money to local people.
Saving these animals means saving the ocean for everyone.
Common mistakes
Thinking only noise harms dolphins and whales. Many other dangers exist.
Believing plastic is not a big problem. Even small bits can kill these animals.
Forgetting that climate change affects sea animals, not just land animals.
Remember it
Dolphins and whales face many dangers: nets, pollution, hunting, boats, and climate change.
