The new paradigm of ecological justice is addressed in this book as a legal model, but at the same time physical, economic, political and ethical. At present the accumulation of wealth, as the essence that governs the operation of the capitalist economic system, is only possible under conditions of ecological plunder and undermining social rights. Science, on the other hand, justifies the radicality of a socioecological reason for the defense of the common goods of humanity, from the spaces of economics and law. Increasing human intervention in natural systems has ushered in a new geological age: the Anthropocene. Among the vast array of human-induced disturbances on the planet are global warming and related climatic change. Warming of the climate system is a global phenomenon and one of the most serious threats to all continents and oceans. Scientific studies show the observations made all over the planet. The alteration of the environmental balance between man and nature over millennia poses risks such as food insecurity, which especially affects the lives of poor countries and people, and traces a black panorama if not acted on time. To correct this, the universal agreement on climate change at the Paris Summit in 2015 offers some solutions. Simultaneously, the technological advance, so contradictory, awakens the reflection and the new foundations of an ecological ethics. An ethic of responsibility with future generations and planet Earth, which inspires the demands of social and ecological justice from social movements and criticism to the obstacles of law and politics that do not pose any radical. In order for the paradigm shift to become real, one of the premises is to facilitate access to the administration of justice for the new socioecological demands of citizens and eliminate procedural obstacles that obey a past era and do not respond to ecological problems And social that carries out the present time.
