Planet at the crossroads. An authoritative United Nations report says human activity is likely
to mark more than two-thirds of the Earth’s surface within 30 years. [BBC News: sci/tech]
The article actually says, “More than 70% of the Earth’s land surface could be marked by the impact of cities, roads, mining and other human developments.” Of course most of the Earth’s surface if water, which is rather hard to build roads and cities on. This sort of thoughless mistake is pretty typical of the article, which assumes, as the UN does, that the presence of humans is a bad thing.
