To move forward we need to look back. The clues towards a sustainable future are hidden in our heritage.
Mankind has been heedlessly defiling the natural environment in which we live. Our dependence on plastics and our fishing techniques endanger the oceans as habitats for marine life. Our excessive consumption of beef fills the atmosphere with climate-warming methane. Our combustion of fossil fuels renders the air noxious. Extreme weather is becoming the norm. Humanity's ways of living are too often unsustainable.
