About the book: year / The Green Revolution, which began in 1943 in Mexico, was a particular supposed boon for developing countries due to the increase in its agricultural production. Sixty-four years later, the technologies of the Green Revolution are still powerful in terms of agricultural production, but we find that this has come at a cost of, among other things, environmental degradation, erosion, soil degradation, water depletion and pollution, and loss of biodiversity. Today humanity is faced with many problems on a global scale. These problems include poverty and hunger, growing concerns about fossil fuel consumption, environmental degradation, loss of biodiversity, health problems - especially among women and children - and growing global inequalities in educational levels. There is no shortage of solutions for each of these problems, but there is one solution - perennial polyculture agriculture - that can provide answers to each of these problems and deserves more attention than it has received. This expanded opinion argues for the prospect of perennial polyculture as a positive contribution to solving a wide range of global problems and suggests steps that should be taken to further explore this prospect.
