The Earth is a living planet, now this "macro body" is feverish and humanity that dwells in panic every flood, storm, tsunami and another earthquake.
And yet we continue, year after year, to help increase the temperature inside the greenhouse that protects us for millions of years.
The 9 warmest years since 1880, are between 2000 and 2012, according to NASA scientists.
The medium-term forecasts are alarmist, a warming of 1.4 to 5.8 degrees Celsius is foreseen by the end of the 21st century. This will be the largest increase in Earth's temperature since 10,000 years.
Between the ice age, 20,000 years ago and the hottest period, there are 7000 years, there were only 7 ° C difference. If the temperature of the Earth increases by a century of 5.8 degrees Celsius as advertised, the living world will have to adapt very quickly. The first consequences of global warming are already visible. Indeed we see every day as glaciers retreat, floods are more devastating, that periods of drought return more frequently, the Arctic sea ice decreases... However, the scale of humanity is so small compared to the geologically it is pretentious to believe that warming of this magnitude has never happened in the past. There are certainly many factors that can influence the Earth's climate and we are far from knowing all. However, many analyzes show that our involvement in global warming temperatures on the surface of the Earth. We are aware of this and it is likely, despite "all our efforts," we will not be able to change the temperature curve started. The global ecological footprint, created in the 1990s by MM. Mathis Wackernagel and William Rees, two researchers from the University of British Columbia in Vancouver, is the pressure exerted by humanity over nature.
It assesses the productive area required for a population to meet its consumption of resources and needs to absorb waste.
Since 2007 this demand exceeds the capacity limits of ecosystem restoration.
The human economy is in ecological overshoot.
The overall ecological footprint of humanity has increased by 50% between 1970 and 1997, an increase of approximately 1.5% per year.
The increasing proliferation of the human species on the planet can cause a real environmental collapse as humanity uses water faster than it is recharged into the ground. it cut forests faster than they can regenerate, emits CO2 into the atmosphere faster than it can absorb.
Human societies are still animal societies, they exploit until exhaustion total resources available to them. Sooner or later, we must reorganize and adapt as we needed every time the "Nature".
