According to the report of WWF (World Wildlife Fund), the increased need for humanity in natural resources is such that it will take additional land before 2040.
The report also gives an indication of what is called the ecological footprint, measuring the natural resource needs of an individual or population, of course for food but for everything else (different materials, occupancy land for housing and transport carbon balance...).
It is expressed in global hectares, giving the surface of land and sea required to meet these needs and to recycle waste products. According to figures from the report, the need exceeds the capacity of the planet since the late 1980s.
In 2005, the Ecological Footprint of all mankind was 17.5 billion global hectares. However, the production capacity of the planet expressed with the same unit, reached only 13.6 billion.
This difference of 29%, corresponds to the depletion of resources. At this rate, says the report, the gap will reach 100% during the 2030s.
What is telling in this organization that we will then have two Earths to our current lifestyles are maintained.
But there are not two Earths to us, so it's the man, merely renewable resources.
