The pressure is coming from the size and activities of the human population. In the near past, human population has grown exponentially, increasing more than 4 fold in a century. At the present, human population is starting a demographic transition, slowing down its growth rate. We can expect - or hope - human population to stabilize in less than a century, give or take. This is good news. But the size of the human population is staggering and already stretching Earth's life support system. As we increase our share of a finite planet, the resources for all other forms of life are rapidly diminishing. To make matters worse, climate change is increasing pressure on many wild populations precisely when they have diminishing options to adapt and move, accelerating their demise.

Technology might be able to mitigate our impact on Earth’s biodiversity in the future. But many life forms will no longer be around when that happens. Many are already extinct. Many, many more are walking dead.
