The theme for World Environment Day this year, the International Year of Biodiversity, is 'Many Species, One Planet, One Future'.
Scientists are unsure about the number of species that share our planet. Whilst about 2 million different species have been identified, estimates of the total number of species varies from 5 million to 100 million!
Humans are among the handful of species whose numbers are growing – most animals and plants are becoming rarer and fewer with over 17,000 known to be threatened with extinction.
Human activity is responsible. With our present approach to development, we have caused the clearing of much of the original forest, drained half of the world’s wetlands, depleted three quarters of all fish stocks, and emitted enough heat-trapping gases to keep our planet warming for centuries to come.
World Environment Day asks us to consider carefully the actions each of us must take, and then address ourselves to our common task of preserving all life on Earth. Some practical steps we can take can be found on the above website.
