(Too) deep impact
WWF released it’s last Living Planet Report. Just to clarify his importance, take a look:
WWF’s 2006 Living Planet Report, the group’s biennial statement on the state of the natural world, says that on current projections humanity will be using two planets’ worth of natural resources by 2050 — if those resources have not run out by then. It also confirms the trend of biodiversity loss seen in previous Living Planet reports.
The first, the Living Planet Index, measures biodiversity, based on trends in more than 3,600 populations of 1,300 vertebrate species around the world. In all, data for 695 terrestrial, 344 freshwater and 274 marine species were analyzed. Terrestrial species declined by 31 per cent, freshwater species by 28 per cent, and marine species by 27 per cent.
The second index, the Ecological Footprint, measures humanity’s demand on the biosphere. Humanity’s footprint has more than tripled between 1961 and 2003. This report shows that our footprint exceeded biocapacity by 25 per cent in 2003. In the previous report (based on data to 2001), this figure was 21 per cent. The carbon dioxide footprint, from the use of fossil fuels, was the fastest growing component of our global footprint, increasing more than ninefold from 1961 to 2003.
