The voluntary approach to corporate social responsibility has failed in many cases.

Many scientists and economists also say putting a price on carbon through carbon taxes and/or cap-and-trade is necessary.

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.

My Prime Minister regards the economy as our highest priority and forgets that economics and ecology are derived from the same Greek word, oikos, meaning household or domain. Ecology is the study of home, while economics is its management. Ecologists try to define the conditions and principles that enable a species to survive and flourish. Yet in elevating the economy above those principles, we seem to think we are immune to the laws of nature. We have to put the ‘eco’ back into economics.

As parents, grandparents, uncles and aunts we need to start getting out into nature with the young people in our lives. Families play a key role in getting kids outside.

It's not unexpected that shooting massive amounts of water, sand, and chemicals at high pressure into the earth to shatter shale and release natural gas might shake things up. But earthquakes aren't the worst problem with fracking.
