What I did: I went on to BBC world, hoping to find interesting articles about tigers. What I found, didn't disappoint me.
What I learnt:
>In April 2016, the number of tigers went up. The latest global census counted 3,890 Tigers, compared to just 3,200 Tigers in 2010.
> people are finding ways to live alongside tigers.
>India is home to around half of the world's tigers, and in several parts of the country, some local tribes co-exist fairly happily with tigers.
> tribal communities might be helping the Tigers. Survival International, a charity aiming to protect the rights of indigenous peoples, says "tribal peoples are the best conservationists and guardians of the natural world."
Summary: Tiger populations are rising due to tribal people living alongside the tigers and conserve the tigers living habitats.
