Since their appearance on earth, human societies have had to face a double challenge: that of being entirely dependent on natural resources and that of belonging to ecosystems providing services essential to their well-being. These ecosystems tirelessly produce the water, the oxygen, the
wood, and the plants that we consume. They absorb the floods, produce a large part of our medicines, and shelter resources that may be unknown today but essential tomorrow. Finally, they offer us the cultural amenities necessary for our reinvention !
Despite this dependence, our societies especially the so-called industrial ones developed from the end of the 19th century, act as if they no longer belong to these natural systems. By extracting more and more resources to meet their ever-increasing needs, human societies have exhausted many ecosystems.
Modernity obliges us to consider that natural environments have become the most precious assets because of the essential ecological services provided to human populations.
In 2005, researchers around the world identified the relied upon services provided by Nature. Their observations are clear: all our human needs come from Nature: water, air, food, health (70% of medicines extracted from “wild” plants) soil, forests…
Human beings know how to extract, transport, and transform raw materials. But we are unable to create them !
Humanity directly depends on the resilience and proper functioning of these ecosystems, and the quality and quantity of the natural goods and services that result from them. This is why it is time to deal with the trajectories and “health” of our natural heritage.
