Last year was the most perilous ever for people defending their community’s land, natural resources or wildlife, with new research showing that environmental defenders are being killed at the rate of almost four a week across the world. Two hundred environmental activists, wildlife rangers and indigenous leaders trying to protect their land were killed in 2016, according to the watchdog group Global Witness – more than double the number killed five years ago.. John Knox, UN special rapporteur on human rights and the environment, said: “There is now an overwhelming incentive to wreck the environment for economic reasons... There is an epidemic now, a culture of impunity, a sense that anyone can kill environmental defenders without repercussions, eliminate anyone who stands in the way. It [comes from] mining, agribusiness, illegal logging and dam building." ...This is why the Guardian is today launching a project, in collaboration with Global Witness, to attempt to record the deaths of everyone who dies over the next year in defence of the environment. We will be reporting from the world’s last wildernesses, as well as from the most industrialised countries on the planet, on the work of environmental defenders and the assaults upon them.
