If we have any hope of finding ways for seven billion people to live well on planet with finite resources, we have to learn to use our resources efficiently. Plastic bags are neither efficient nor environmentally friendly.

The terrible part of this looming catastrophe is that people have been working on solutions for years and have developed concrete steps to massively reduce our energy use, while stimulating whole new industries and technologies that are more efficient and affordable.

But human borders mean nothing to air, water, windblown soil or seeds or migrating fish, birds or mammals.

On December 7, 1941, an event took place that had nothing to do with me or my family and yet which had devastating consequences for all of us - Japan bombed Pearl Harbour in a surprise attack. With that event began one of the shoddiest chapters in the tortuous history of democracy in North America.

Wind power, if not properly planned and sited, can harm birds and bats (although Danish studies of 10,000 bird kills revealed that almost all died in collisions with buildings, cars and wires; only 10 were killed by windmills). Alternative energy sources are absolutely necessary. Global warming will kill birds and bats, as well as other species, in much greater numbers than wind power.

Canada, more than any nation, will be affected by rising sea levels from global warming.

Fukushima is the most terrifying situation I can imagine.
