Humans are an infant species, a mere 150,000 years old. But, armed with a massive brain, we've not only survived, we've used our wits to adapt to and flourish in habitats as varied as deserts, Arctic tundra, tropical rainforests, wetlands and high mountain ranges.

Human use of fossil fuels is altering the chemistry of the atmosphere; oceans are polluted and depleted of fish; 80 per cent of Earth's forests are heavily impacted or gone yet their destruction continues. An estimated 50,000 species are driven to extinction each year. We dump millions of tonnes of chemicals, most untested for their biological effects, and many highly toxic, into air, water and soil. We have created an ecological holocaust. Our very health and survival are at stake, yet we act as if we have plenty of time to respond.
