Revealing the truth of the decline in sparrow populations in 6 points. Why are they in danger condition and why do we have to protect them before it's too late?

1. Cities and Buildings Taking Over:

As cities grow, there are few places for sparrows to build their nests. The spaces where they used to live are disappearing because of all the buildings.

2. Farm Changes:

Farms have also changed. Big farms and the use of strong chemicals to protect crops mean there are fewer bugs and seeds for sparrows to eat. This makes it hard for them to find enough food.

3. Not Enough Food:

In general, there's less food for sparrows. Pesticides (chemicals used to kill bugs on crops) can make it difficult for sparrows to find the insects they like to eat.

4. Dirty Air:

In cities, the air is not clean enough. This can make sparrows sick and weak. When they're not healthy, it's harder for them to have babies and survive.

5. Strange Weather:

The weather is changing because of global warming. This affects when bugs come out and when plants make seeds. Sparrows depend on these things for their food, so weather changes also make life tough for them.

6. Other Birds Taking Over:

Some other birds that are not from India (like the house finch) are moving in and taking the places where sparrows used to live. This makes it harder for sparrows to find good spots to build nests and raise their chicks.
