What about our children and grandchildren and their children and grandchildren? Do we not want them to live healthy and happy lives?

We can't blame children for occupying themselves with Facebook rather than playing in the mud. Our society doesn't put a priority on connecting with nature. In fact, too often we tell them it's dirty and dangerous.

If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.

Most North Americans know that human-caused global warming is real, even if political leaders don't always reflect or act on that knowledge.

Any politician or scientist who tells you these [GMO] products are safe is either very stupid or lying.

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.

It is clear that while science provides insights into the complexity of the world around us, those insights...present a fractured mosaic rather than a seamless whole. There are profound limits to science that must be recognized if we are to minimize the destructive consequences of using the powers provided by scientific discovery.
