From 1990 to 2013, the notorious tiger poacher Kuttu Bahelia and his extended family – brothers, uncles, and their wives and children – reportedly killed hundreds of tigers and leopards in the tiger-rich Indian states of Maharashtra and Karnataka, according to law enforcement informants and media reports. “Even if half that [estimate] is correct, it is still a very significant number,” says Belinda Wright, who directs the non-profit Wildlife Protection Society of India (WPSI).

The Earth’s front-line defenders are disappearing at an astonishing rate. On average three environmental activists were killed each week in 2015, according to a recent report from the United Nations special rapporteur on the situation of human rights defenders.

In total, 185 killings of environmental defenders were recorded by Global Witness in 2015.

As global climate change affects livelihoods across the world, migration patterns are also changing.
