Treaties, agreements and organizations to help settle disputes may be necessary, but they often favor the interests of business over citizens.
We're in a giant car heading towards a brick wall and everyone's arguing over where they're going to sit.
The damage that climate change is causing and that will get worse if we fail to act goes beyond the hundreds of thousands of lives, homes and businesses lost, ecosystems destroyed, species driven to extinction, infrastructure smashed and people inconvenienced.
Doing all we can to combat climate change comes with numerous benefits, from reducing pollution and associated health care costs to strengthening and diversifying the economy by shifting to renewable energy, among other measures.
From year to year, environmental changes are incremental and often barely register in our lives, but from evolutionary or geological perspectives, what is happening is explosive change.
Education has failed in a very serious way to convey the most important lesson science can teach: skepticism.
In the environmental movement, every time you lose a battle it's for good, but our victories always seem to be temporary and we keep fighting them over and over again.
Over and over, we hear politicians say they can't spend our tax dollars on environmental protection when the economy is so fragile.
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.
From year to year, environmental changes are incremental and often barely register in our lives, but from evolutionary or geological perspectives, what is happening is explosive change.
Beyond reducing individual use, one of our top priorities must be to move from fossil fuels to energy that has fewer detrimental effects on water supplies and fewer environmental impacts overall.
The failure of world leaders to act on the critical issue of global warming is often blamed on economic considerations.
We must pay greater attention to keeping our bodies and minds healthy and able to heal. Yet we are making it difficult for our defences to work. We allow things to be sold that should not be called food. Many have no nutritive value and lead to obesity, salt imbalance, and allergies.
Global trade has advantages. For starters, it allows those of us who live through winter to eat fresh produce year-round. And it provides economic benefits to farmers who grow that food.
The human brain now holds the key to our future. We have to recall the image of the planet from outer space: a single entity in which air, water, and continents are interconnected. That is our home.
We must reinvent a future free of blinders so that we can choose from real options.
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.
For the sake of our health, our children and grandchildren and even our economic well-being, we must make protecting the planet our top priority.
Thanks to evolution, our bodies have powerful ways to ward off illness and infection and enable us to live long and healthy lives. Why, then, do health costs continue to climb at unsustainable and frightening rates?
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.
Doing all we can to combat climate change comes with numerous benefits, from reducing pollution and associated health care costs to strengthening and diversifying the economy by shifting to renewable energy, among other measures.
If America wants to retain its position as a global power, its president must listen to the people and show strong leadership at this turning point in human history.

Most North Americans know that human-caused global warming is real, even if political leaders don't always reflect or act on that knowledge.
If America wants to retain its position as a global power, its president must listen to the people and show strong leadership at this turning point in human history.
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.
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.
