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 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.
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.
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.
The human brain had a vast memory storage. It made us curious and very creative. Those were the characteristics that gave us an advantage - curiosity, creativity and memory. And that brain did something very special. It invented an idea called 'the future.'
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.
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.
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.
Our beliefs, our values shape the way we look out at the world and the way we treat it. If we believe that we were here, placed here by God, that this - all of this creation is for us, it's for us to go and occupy, dominate and exploit, then we will proceed to do that.
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.
Change is never easy, and it often creates discord, but when people come together for the good of humanity and the Earth, we can accomplish great things.
Just as fossil fuels from conventional sources are finite and are becoming depleted, those from difficult sources will also run out. If we put all our energy and resources into continued fossil fuel extraction, we will have lost an opportunity to have invested in renewable energy.
We need love, and to ensure love, we need to have full employment, and we need social justice. We need gender equity. We need freedom from hunger. These are our most fundamental needs as social creatures.
Some solutions are relatively simple and would provide economic benefits: implementing measures to conserve energy, putting a price on carbon through taxes and cap-and-trade and shifting from fossil fuels to clean and renewable energy sources.
You would have thought that our first priority would be to ask what the ecologists are finding out, because we have to live within the conditions and principles they define. Instead, we've elevated the economy above ecology.
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.
My parents survived the Great Depression and brought me up to live within my means, save some for tomorrow, share and don't be greedy, work hard for the necessities in life knowing that money does not make you better or more important than anyone else. So, extravagance has been bred out of my DNA.
We humans have become dependent on plastic for a range of uses, from packaging to products. Reducing our use of plastic bags is an easy place to start getting our addiction under control.
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.
People don't even understand that every bit of our food was once alive. We take another creature, plant, animal, microorganism, tear it apart in our mouths. And incorporate those molecules into our own bodies. We are the Earth in the most profound way.
