The Earth’s natural resources are being depleted so quickly that the equivalent of two planets would be required to sustain current lifestyles by the mid-2030s, warn leading environmental groups.

It warns that reckless consumption of “natural capital” is endangering the world’s future prosperity, with clear economic impacts, including high costs for food, water and energy.
