As reported by Greenpeace:
"Kleenex, one of the most popular brands of tissue products in the world, contributes to the destruction of ancient forests in Canada. Its manufacturer, the Kimberly-Clark corporation, has been unwilling to improve its practices, continuing to rely on paper and pulp made from clearcut ancient forest including Canada’s Boreal forest. Kimberly-Clark clears these ancient forests, essential in fighting climate change and providing home to wildlife like caribou, wolves, eagles and bears, into products that are flushed down the toilet or thrown away.
In response to this wasteful destruction, Greenpeace has launched an international public campaign against Kimberly-Clark with US-based Natural Resources Defence Council and other environmental organizations."
