Hydraulic fracturing requires massive amounts of water. Disposing of the toxic wastewater, as well as accidental spills, can contaminate drinking water and harm human health.
If we want to address global warming, along with the other environmental problems associated with our continued rush to burn our precious fossil fuels as quickly as possible, we must learn to use our resources more wisely, kick our addiction, and quickly start turning to sources of energy that have fewer negative impacts.
More than a billion people lack adequate access to clean water.
Because countries often have differing political and economic systems, agreements are needed to protect those invested in trade.
Treaties, agreements and organizations to help settle disputes may be necessary, but they often favor the interests of business over citizens.
We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.
Just as human activity is upsetting Earth's carbon cycle, our actions are altering the water cycle.
Scientists and supercomputers have amplified our ability to look ahead. For decades, experts have warned us that human numbers, technology, hyper-consumption and a global economy are altering the chemical, geological, and biological properties of the biosphere.
The medical literature tells us that the most effective ways to reduce the risk of heart disease, cancer, stroke, diabetes, Alzheimer's, and many more problems are through healthy diet and exercise. Our bodies have evolved to move, yet we now use the energy in oil instead of muscles to do our work.
Our most fundamental social need, it turns out, to my amazement, is love. Now, I'm not a hippie-dippie whatever. If you look at the literature, our most fundamental need for children is an environment of maximum love, and that they can be hugged, kissed, and loved. That's what humanises us and allows us to realise our whole dimension.
Humans are distinguished from other species by a massive brain that enables us to imagine a future and influence it by what we do in the present. By using experience, knowledge and insight, our ancestors recognized they could anticipate dangers and opportunities and take steps to exploit advantages and avoid hazards.
The government's desire to expand global trade may be understandable, but we mustn't give away too much. We must tell our elected representatives to at least delay the Canada-China FIPA until it has been examined more thoroughly, and to reconsider the inclusion of investor-state arbitration mechanisms in all trade deals.
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.
We're in a giant car heading towards a brick wall and everyone's arguing over where they're going to sit.
Some argue we should get coal, oil and gas out of the ground as quickly as possible, build more pipelines and make as much money as we can selling it here and abroad. Their priorities are the economy and meeting short-term energy needs so we can live the lives to which we've become accustomed.
I read in 'Life' magazine that Asians had developed an operation to enlarge eyes, and I yearned to have this done. I wanted to dye my hair brown and to anglicize my name. Self-hate was the most terrible cost of the war years for me.
We pride ourselves on our democratic traditions, but in Canada, women couldn't vote until 1918, Asians until 1948, and First Nations people living on reserves until 1960.
I always felt that if someone shot me, it would be great for the environmental movement, because they would make me a martyr. Our biggest fear was our children, because there was a tremendous amount of threat and intimidation, and my wife was terrified that the children might be grabbed or assaulted in some way. That was the real fear.
Many instances of persecution and killing have occurred in countries with atrocious human rights records such as Sri Lanka, Guatemala and the Democratic Republic of Congo.
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.
