Nature crisis: Humans ‘threaten 1m species with extinction’
The world’s population has doubled since 1970, the global economy has grown four-fold, while international trade has increased 10 times over.
To feed, clothe and give energy to this burgeoning world, forests have been cleared at astonishing rates, especially in tropical areas.
Between 1980 and 2000, 100 million hectares of tropical forest were lost, mainly from cattle ranching in South America and palm oil plantations in South East Asia.
Faring worse than forests are wetlands, with only 13% of those present in 1700 still in existence in the year 2000.
Our cities have expanded rapidly, with urban areas doubling since 1992.
