The Earth and us

Most citizens understand today’s ecological issues, but lack the basic knowledge to really take them on board. This book aims to provide an environmental assessment of the knowledge, experiences and concepts in understanding ecological systems, which have already been very developed and discussed since the 20th century, but whose objectives are still far from being achieved. The aim is to propose possible orientations that will enable us to act in the best possible way and with full knowledge of the facts. The guiding thread of the approach is to recall the main ways in which life on Earth functions. These principles, better understood and acknowledged by all, should enable the non-specialist reader to form his or her own opinion of the complexity of environmental issues.
