    Human demands for natural resources have doubled in less than 50 years and are now beyond what the earth can provide, a report warned. If humans carry on like this, we will need two earths by 2030. The population of wildlife has fallen by 60% in thirty years.

The report said British people are consuming (消耗) far more than the earth can deal with. If everyone lived such a lifestyle, humans would need 2.75 planets to survive. People are now living lifestyles which would require 1.5 planets, though there are great differences between rich and poor nations.

Researchers studied the global change in land use and water consumption. The UK comes 31st in a list of countries based on “ecological footprint (生态足迹)” that measures how much land and sea each person needs to produce the resources they consume and to absorb (吸收) the wastes. The UK has fallen down from 15th place in the last report two years ago to 3lst place, but the WWF believes it is an increase in other countries’ efforts rather than a reduction in the UK’s use of resources.

Ireland has the 10th highest ecological footprint, while the United Arab Emirates, Qatar, Denmark, Belgium and the US are the five worst countries for over-consumption of resources. The study suggests if the expected global population of 9.2 billion in 2050 were to eat a Malaysian diet, 1.3 planets would be needed but if everyone were to eat an Italian diet, humans would need almost two planets. Those countries that can provide the highest quality of life using the lowest amount of resources will not only serve the global interest, but will be the leaders in a resource-limited world.
