2012 edition of the WWF "Living Planet Report"

The 2012 edition of the LPR highlights the tremendous pressure that humanity is putting on our planet. We are using 50 per cent more resources than the Earth can provide. By 2030, even two planets will not be enough.

Our natural capital is declining and our Ecological Footprint is increasing. Urgent action is needed to ensure that we can live in harmony with nature.

Human population dynamics are a major driving force behind environmental degradation. One aspect of this is the overall size of the global population, which has more than doubled since 1950 - to 7 billion in 2011 and is forecast to reach just over 9.3 billion people by 2050.

Rising consumption trends in high-income groups around the world and in BRIICS countries, combined with growing population numbers, provide warning signs of the potential for even larger footprints in the future.

We can create more just and equitable societies - providing food, water and energy for all - through the sustainable management of the Earth’s natural capital.
