Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

A population explosion of mountain pine beetles have plagued British Columbia’s forests since the 1990s. The beetle, Dendroctonus ponderosae, has destroyed large tracts of forest throughout the province. Forests have economic value, and they provide habitat and food for wildlife. In addition, they play an important role in Earth’s carbon cycle, which affects climate. Healthy, growing forests take up carbon dioxide and produce oxygen. Dead forests produce carbon dioxide when trees decay. Some of the worst damage appears near 52 degrees north and 124 degrees west.
