WCS launches new program aimed at reducing unsustainable hunting overseas
... 1999 WCS study, published in the journal Science, documented that more than one million metric tons of wild meat (commonly called "bushmeat") was coming out of Africa's tropical forests each year.According to WCS, a further part of the dilemma is that tropical forest peoples across the globe still depend on wi...Extreme climate variance sped extinction of local butterfly populations, researchers say
