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.
David Suzuki
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.
The future doesn't exist. The only thing that exists is now and our memory of what happened in the past. But because we invented the idea of a future, we're the only animal that realized we can affect the future by what we do today.
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.'
I can't imagine anything more important than air, water, soil, energy and biodiversity. These are the things that keep us alive.
We're in a giant car heading towards a brick wall and everyone's arguing over where they're going to sit.
Scientists have been warning about global warming for decades. It's too late to stop it now, but we can lessen its severity and impacts.
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.
There are more humans than all of the rabbits on earth. There are more of us than all the wildebeests, than all the rats, than all the mice. We are the most numerous mammal on the planet. But because we're not like rabbits or rats or mice, we have technology, we have a consumptive appetite, we have a global economy.
Our personal consumer choices have ecological, social, and spiritual consequences. It is time to re-examine some of our deeply held notions that underlie our lifestyles.
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.
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.
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.
More than a billion people lack adequate access to clean water.
Ultimately we need to recognize that while humans continue to build urban landscapes, we share these spaces with others species.
Nature surrounds us, from parks and backyards to streets and alleyways. Next time you go out for a walk, tread gently and remember that we are both inhabitants and stewards of nature in our neighbourhoods.
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.
The truth is, as most of us know, that global warming is real and humans are major contributors, mainly because we wastefully burn fossil fuels.
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.
Outright bans on plastic bags may not be the best solution, but education and incentives to get people to stop using them are necessary.
My earliest memory from childhood is of fishing with my father. And I remember vividly we were in a store, and we were buying a pup tent to go on our first camping trip.
The increasing frequency of extreme weather events, droughts and floods is in line with what climate scientists have been predicting for decades - and evidence is mounting that what's happening is more severe than predicted, and will get far worse still if we fail to act.
Canada should always open its doors to those who are oppressed or in cases of emergency. When Canada offered refuge to 50,000 boat people in Vietnam in the 1970s, I was particularly proud to be Canadian.
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.
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.
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.
Education has failed in a very serious way to convey the most important lesson science can teach: skepticism.
The voluntary approach to corporate social responsibility has failed in many cases.
Treaties, agreements and organizations to help settle disputes may be necessary, but they often favor the interests of business over citizens.
We must reinvent a future free of blinders so that we can choose from real options.
Pearl Harbor was the defining event in my life. It shaped who I am, and all of my hang-ups and my drives, I think, stem from that.
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.
Water is our most precious resource, but we waste it, just as we waste other resources, including oil and gas.
If you're not being pessimistic, you're not being very realistic. But I think one must always have hope, and when you have children, of course, you have no choice but to work your tail off to try and protect the future for your children. And that is infused by hope in the end.
I've always been more interested in organisms that can move on their own than in stationary plants. But when I canoe or hike along the edge of lakes or oceans and see trees that seem to be growing out of rock faces, I am blown away. How do they do it?
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.
Rapid population growth and technological innovation, combined with our lack of understanding about how the natural systems of which we are a part work, have created a mess.
I feel humiliated that I live in a country that demands more already. Why do we cling to the notion that not only must we maintain the current level of consumption, but that it must continue to grow by an exponential factor of 2 to 7 percent every year?
Conserving energy and thus saving money, reducing consumption of unnecessary products and packaging and shifting to a clean-energy economy would likely hurt the bottom line of polluting industries, but would undoubtedly have positive effects for most of us.
We have much to learn by studying nature and taking the time to tease out its secrets.
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.
Corporations are economic entities or structures, and yet they're allowed to fund political candidates, and when those candidates are elected, guess who gets in the door first? It's corporations.
Over and over, the economy has determined the extent of our response, but how much value does it place on breathable air, drinkable water, edible food and stable weather and climate? Surely the economy is the means to a better future, not an end in itself. Surely it must be subordinate to a rich, diverse ecosphere that sustains all life.
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.
It doesn't give me any satisfaction to think that my concerns will be validated by my grandchildren's generation. I would love to be wrong in everything. My grandchildren are my stake in the near future, and it's my great hope that they might one day say, 'Grandpa was part of a great movement that helped to turn things around.'
Too often, governments are quick to use excessive force and even pervert the course of justice to keep oil and gas flowing, forests logged, wild rivers dammed and minerals extracted. As the Global Witness study reveals, citizens are often killed, too - especially if they're poor and indigenous.
Japanese people cut their energy use by 25 percent immediately after Fukushima. They showed there was huge opportunity there. And instead, the government simply wants to get those plants up and running again.
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.
Environmentalism is a way of seeing our place within the biosphere.
Although it's difficult, if not impossible, to put a dollar value on the numerous services nature provides, leaving them out of economic calculations means they are often ignored.
