Endangered tigers have made a remarkable comeback in five countries

Some info on the TX2 initiative mentioned in the news:

Historically, tigers once ranged widely across Asia, but in recent decades, populations have been restricted to 13 countries, namely Bangladesh, Bhutan, Cambodia (locally extinct), China, India, Indonesia, Lao PDR (locally extinct), Malaysia, Myanmar, Nepal, Russia, Thailand, and Viet Nam (locally extinct).

In 2010, when the tiger population had dipped to as few as 3,200, leaders from the 13 countries that currently or recently had tigers came together and set out to achieve an unprecedented goal: doubling the number of tigers in the wild by 2022, the next Chinese Year of the Tiger.
