Planetary Boundaries[1]
In the 1960s, humans took about three-quarters of what the planet could regenerate annually. By 2016 this rose to 170 percent. The planet cannot keep up with current human demand and time is running out.[2]
The world won't end tomorrow, next year or the year after. But 97% of scientists (i,e, 100% minus the lobbyists) predict it will get progressively worse, each day we do nothing we roll a dice where the probability of something seriously bad happening goes up and up. We have already seen the following:
- Climate change - since records began in 1880, nineteen of the twenty hottest years have occurred since 2000[3].
- Biodiversity loss - there has been a 68% average decline in the population sizes of mammals, birds, amphibians, reptiles, and fish between 1970 and 2016[4].
- Deforestation - more than half the world’s tropical forests have been destroyed since the 1960s[5].
- Ocean acidification - more CO2 in the atmosphere means more acidity in the oceans.
- Microplastics via overconsumption - humanity is running an ecological Ponzi scheme in which society robs nature and future generations to pay for boosting incomes in the short term.[2]
- Ozone depletion, the nitrogen cycle, the phosphorus cycle...
These issues combined are accelerating us towards collapse. It is predicted that specific areas of the world will become uninhabitable by 2100[6] these are the areas which will be effected the most:
