Human demands on natural resources are so great we need one-and-a-half Earths to sustain our gorging lifestyles.
Our take up of food, land, natural minerals and animals has doubled in under 50 years, says new research.
Britain came 31st in a list of countries based on their ?ecological footprint? ? the amount of land and sea each person needs to provide the food, clothes and other products they consume.
The country has ?improved? from having the 15th biggest footprint two years ago ? but this is down to an increase in other countries? impact rather than a reduction in Britain.
Wildlife in tropical countries is also under huge pressure, with populations of species falling by 60 per cent in three decades, the report by WWF, the Zoological Society of London and the Global Footprint Network said.
If humanity carries on as it is in use of resources, globally it will need the capacity of two Earths by 2030, the report said.
?The depletion of natural resources caused by human consumption also poses risks to our economic security: for instance, scarcity of resources and degraded natural systems will increase the price of food, raw materials and other commodities,? said WWF-UK chief executive David Nussbaum.
