Today the world is 40 years in to an extinction period, with plants and animals being lost at a rate not seen since the time of the dinosaurs. The dinosaurs were unlucky as their extinction was caused by a thumping great rock hitting the Earth, and it was almost instant. The modern extinction is a form of lingering death creeping up on us almost unseen....
Since the 1970s the planet has lost millions of sq/km of rain forests, heathlands and jungle and according to the WWF global wildlife populations have dropped more than half. The only mammal top have grown its population by any degree is Homo Sapiens sapiens - us. Up from 3.5bn to 7.7bn in the same period.
In the 70s James Lovelock came up with the Gaia principle. It proposed that all life interacted with its surroundings in a synergistic and self-regulating system. This helped to maintain and perpetuate the conditions for life on the planet.
It does not quite work as expected because the planet is too big, but it is spot-on at more local levels. If a lot of these local problems are added together we do get one big problem. This is where we are today.
We have become our own lingering death
