The alarm we had launched , resources are finite, the Earth moves in reserve.
September 25 is Earth Overshoot Day , the time of the year in which the human species has spent renewable resources available and begins to devour those who should support future generations.
to calculate this date is Global Footprint Network the association measure the ecological footprint of humanity, ie mark product on the planet from our daily lives.
WORLD ECOLOGICAL FOOTPRINT
The impact has been more consistent since the beginning of ' nineteenth century, but only in recent decades has begun the dramatic growth that is continuing. In 1961 humanity consumed half the planet's biological capacity. In 1986 we pushed to the limit and reached the first Eeath Overshoot Day: December 31 of that year, the available resources were finite.
In 2050, if the energy crisis there has forced the ecological wisdom, for keeping the accounts in balance, we need a sister planet to use as a supermarket to pick up raw materials, water, forests and energy.
the alarm time
According to FAO estimates of 2001:
DEFORESTATION: continues at a level of about 13 million hectares per year.
BIODIVERSITY ': Over the past 30 years, the Living Planet Index (wild vertebrates) decreased by 30%.
salinisation: affects 20 million to 30 million of the current 260 million hectares of irrigated land.
OCEAN FISHERIES: 75% is above or in balance with respect to the productive capacities of the sea.
E 'must therefore change the production model , to heal the environment.
