Experts warn repeatedly that we are pushing the ecological boundaries and heading towards destabilization of the planet.

Two big risks are the loss of biodiversity through extinction of plants or animal species, and ecological collapse. Reportedly 83% of the world’s mammal life and half the plants are already things of the past. Is it possible then that we may already have reached, or even crossed, the tipping point?
