Table 27: Seven 'I' solutions for conserving biodiversity

• Investigation: learning how natural systems function

• Information: ensuring that facts are available to inform decisions

• Innovation: finding new ways to use biological resources sustainably

• Incentive: using tools to help biodiversity

• Integration: promoting a cross-sectoral approach to conserving biodiversity

• Indigenous communities: returning management responsibilities to those whose welfare depends on the resources managed

• International cooperation: building productive collaboration for conserving biodiversity

Amount of topsoil created by nature each year 0.4 billion tons

Amount lost to erosion 25.4 billion tons Time it takes the global human economy to consume the equivalent of 22 million tons of oil 1 day

Time it took to the planet to create this energy 10,000 days Number of species lost to extinction each year, on average, during the past 65 million years 1 to 10

Number lost in the past year (conservatively estimated) 1,000 to 10,000

Time it took for the world to lose 1 per cent of its forests, on average, during the 30 centuries prior to the

Industrial Revolution 100 years

Time it is taking to lose 1 per cent now 1 year

Natural Resources: Since 19 70, the world's forests have declined from 4.4 square miles per 1,000 people to 2.8 square miles per 1,000 people. In addition, a quarter of the world's fish stocks have been depleted and another 44 per cent are being fished to their biological limits.
