Unprecedented rates of population growth, swiftly rising incomes and per capita demand, and technological advances, impose requirements on natural systems which may exceed their capacity to respond. As a result the life-support system of the planet may eventually be damaged beyond repair. The fact that perturbations in remote and seemingly unimportant parts of the biosphere can trigger off a chain of cause-effect reactions that ultimately provoke profound changes in the entire system, underlines the absence of world-wide integrated resource management.
Currently (2018), our civilization is running at 40% above its sustainable capacity. We’re rapidly depleting the earth’s forests, animals, insects, fish, freshwater, even the topsoil we require to grow our crops. We’ve already transgressed three of the nine planetary boundaries that define humanity’s safe operating space, and yet global GDP is expected to more than double by mid-century, with potentially irreversible and devastating consequences.
The growth of human activity on the planet has produced effects which are approaching, and in some instances may have exceeded, the thresholds for maintenance of equilibrium balance by the planetary system.
