Our economic system, run for profit and waste and based primarily on the extractive industries, is the cause of climate change. We have wasted the earth's treasure and we can no longer exploit it cheaply.
City farming is not only possible, it is the very definition of the kind of meaningful, sustainable innovation we will need to meet the grand challenges of the 21st century: climate change; population growth; ageing population; urbanization; rising demand for energy, food and water; poverty; and access to healthcare.
Change or be changed, right? And what we mean by that is that climate change, if we don't change course, if we don't change our political and economic system, is going to change everything about our physical world.
As a black person in America, I am twice as likely as a white person to live in an area where air pollution poses the greatest risk to my health. I am five times more likely to live within walking distance of a power plant or chemical facility - which I do.
I play fictitious characters often solving fictitious problems. I believe mankind has looked at climate change in the same way, as if it were a fiction.
Climate change is not a discrete issue; it's a symptom of larger problems. Fundamentally, our society as currently designed has no future. We're chewing up the planet so fast, in so many different ways, that we could solve the climate problem tomorrow and still find that environmental collapse is imminent.
Most reputable scientists agree that climate change is real and that the effects are likely to be bad. But nobody can say for sure exactly what 'bad' means. The safest and most equitable way out of this horrific mess is simple: cut fossil-fuel emissions.
The world will not be destroyed by those who do evil, but by those who watch them without doing anything.
We can choose food that doesn't lead to illnesses like diabetes and cancer. We can choose food that doesn't contribute to water pollution and climate change. And we can choose food that keeps local economies vibrant and farmers on their land.
Without the EPA and the national pollution safeguards it enforces, more children would have asthma. Our water would be less safe. More chemicals would poison our bodies. And more people would die prematurely from respiratory diseases and heart attacks.
Growing hemp as nature designed it is vital to our urgent need to reduce greenhouse gases and ensure the survival of our planet.
Climate change is sometimes misunderstood as being about changes in the weather. In reality it is about changes in our very way of life.
Dealing with global warming doesn't mean we have all got to suddenly stop breathing. Dealing with global warming means that we have to stop waste, and if you travel for no reason whatsoever, that is a waste.
Countries have made impressive pledges to cut carbon pollution, but we have to ensure these promises become actions.
The environment will continue to deteriorate until pollution practices are abandoned.
The solution to climate change is staring us in the face. It's energy policy. If we pursue a global clean-energy economy, we can cut dramatically the amount of carbon pollution we emit into the atmosphere and prevent the worst impacts of climate change.
We need healthy forests if we want to protect our climate. As the climate changes, forests become more vulnerable to insect outbreaks, droughts and wildfires. Simultaneously, when our forests are destroyed, their carbon is released back into the atmosphere, further impacting climate change. It's a horrifying one-two punch.
Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.
We will never end poverty if we don't tackle climate change.
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.
Climate change deniers would have us believe that oil, gas, and coal are the only ways to power a modern, industrialized society. They are wrong, and the proof is all around us.
For 50 years, nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium, lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task, and most of the cost, of making safe sites that have been polluted half-way to eternity.
The strongest governments on earth cannot clean up pollution by themselves. They must rely on each ordinary person, like you and me, on our choices, and on our will.
In tough times, some of us see protecting the climate as a luxury, but that's an outdated 20th-century worldview from a time when we thought industrialization was the end goal, waste was growth, and wealth meant a thick haze of air pollution.
When climate change supercharges weather patterns, the disadvantaged often suffer first and most.
Around the world, climate change is an existential threat - but if we harness the opportunities inherent in addressing climate change, we can reap enormous economic benefits.
The signs of climate change are visible across the nation, from the drought-stricken fields of Central California to the flooded streets of Michigan. Extreme weather is turning people's lives upside down and costing communities millions of dollars in damaged infrastructure and added health care costs.
I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear.
I'm from London, and you hardly see stars because of the pollution of light. But in Arizona, there's nothing, so I can see the stars.
I always saw pollution as theft, and I always thought, 'Why should somebody be able to pollute the air, which belongs to all of us, or destroy a river or a waterway, which is supposed to belong to the whole community?'
Is the minor convenience of allowing the present generation the luxury of doubling its energy consumption every 10 years worth the major hazard of exposing the next 20,000 generations to this lethal waste?
Climate change is an economic, public health, and environmental issue that we have a moral responsibility to address.
We need every person on Earth to acknowledge that climate change is real and encourage each other and our leaders to address the challenge.
Climate change, if unchecked, is an urgent threat to health, food supplies, biodiversity, and livelihoods across the globe.
Our economic system, run for profit and waste and based primarily on the extractive industries, is the cause of climate change. We have wasted the earth's treasure and we can no longer exploit it cheaply.
There is a societal cost of increased pollution, and that's what I'm passionate about as a mother.
For 50 years, nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium, lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task, and most of the cost, of making safe sites that have been polluted half-way to eternity.
The main message we want to get out there is that climate change is caused by the rotten economic system.
Climate change is moving faster than we are, but we don't give up because we know that climate action is the only path.
It's coming home to roost over the next 50 years or so. It's not just climate change; it's sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now.
What they are doing is taking something that otherwise creates pollution and turning it into something useful.
The clear and present danger of climate change means we cannot burn our way to prosperity. We already rely too heavily on fossil fuels. We need to find a new, sustainable path to the future we want. We need a clean industrial revolution.
The main message of Climate Revolution is that climate change is caused by the rotten financial system we've got, designed to create poverty and rip off any profits for a small amount of rich people. Meanwhile, it destroys the earth.
Climate change, demographics, water, food, energy, global health, women's empowerment - these issues are all intertwined. We cannot look at one strand in isolation. Instead, we must examine how these strands are woven together.
The reality of climate change is a stupid thing to argue about.
Global warming is the foreboding thunder in the distance. Ocean acidification is the lightning strike in our front yard, right here, right now.
I felt cheated by the way grown-ups told me that the future of the world was bleak when I became a teenager in the 1970s. The pollution explosion was unstoppable. Global famine was inevitable. I genuinely want the next generation, my own kids, to know that actually it's possible that the future might be better than the past.
The health effects of air pollution imperil human lives. This fact is well-documented.
Given the scale of issues like global warming and epidemic disease, we shouldn't underestimate the importance of a can-do attitude to science rather than a can't-afford-it attitude.
Pollution from human activities is changing the Earth's climate. We see the damage that a disrupted climate can do: on our coasts, our farms, forests, mountains, and cities. Those impacts will grow more severe unless we start reducing global warming pollution now.
Climate change is not a discrete issue; it's a symptom of larger problems. Fundamentally, our society as currently designed has no future. We're chewing up the planet so fast, in so many different ways, that we could solve the climate problem tomorrow and still find that environmental collapse is imminent.
We Are the First Generation that Can End Poverty, the Last that Can End Climate Change
The cost of our success is the exhaustion of natural resources, leading to energy crises, climate change, pollution, and the destruction of our habitat. If you exhaust natural resources, there will be nothing left for your children. If we continue in the same direction, humankind is headed for some frightful ordeals, if not extinction.
Today we're dumping 70 million tons of global-warming pollution into the environment, and tomorrow we will dump more, and there is no effective worldwide response. Until we start sharply reducing global-warming pollution, I will feel that I have failed.
Is the minor convenience of allowing the present generation the luxury of doubling its energy consumption every 10 years worth the major hazard of exposing the next 20,000 generations to this lethal waste?
Climate change increasingly poses on of the biggest long-term threats to investments
