Our ecological footprint now exceeds the earth's ability to support it. Some say we are heading for disaster but others point to new technologies that will sustain our lifestyles.
Living on borrowed time?
The graph shows that the total ecological footprint for the Earth's population exceeds the ability for the planet to renew its resources quickly enough.
This means that we are eating into irreplaceable resources.
However, technological advances and human ingenuity may be able to overcome these problems in the future. For example, modern farming techniques can increase the productivity of land to produce more food.
