"There are no grey areas when it comes to survival... We have to wake up and change."
Greta Thunberg realized at a young age the lapse in what several climate experts were saying and in the actions that were being taken in society. The difference was so drastic in her opinion that she decided to take matters into her own hands. Greta is a 15-year-old Stockholm native who lives at home with her parents and sister Beata. She’s a 9th grader in Stockholm who enjoys spending her spare time riding Icelandic horses, spending time with her families two dogs, Moses and Roxy. She love animals and has a passion for books and science. At a young age, she became interested in the environment and convinced her family to adopt a sustainable lifestyle.

Dr. Katharine Wilkinson delivers a keynote address on Project Drawdown (http://www.drawdown.org/), the the most comprehensive plan ever proposed to reverse global warming, at the opening ceremonies of the #GenerationSDG Summit.
Mark Z. Jacobson - Director of the Atmosphere/Energy Program and professor of civil and environmental engineering at Stanford University—discussed technical and economic roadmaps to convert global energy infrastructure to 100% clean, renewable energy.
Nuclear power: the energy crisis has even die-hard environmentalists reconsidering it. In this first-ever TED debate, Stewart Brand and Mark Z. Jacobson square off over the pros and cons. A discussion that'll make you think -- and might even change your mind.
What if we took out more greenhouse gases than we put into the atmosphere? This hypothetical scenario, known as "drawdown," is our only hope of averting climate disaster, says strategist Chad Frischmann. In a forward-thinking talk, he shares solutions to climate change that exist today -- conventional tactics like the use of renewable energy and better land management as well as some lesser-known approaches, like changes to food production, better family planning and the education of girls. Learn more about how we can reverse global warming and create a world where regeneration, not destruction, is the rule.
Climate change is real, case closed. But there's still a lot we don't understand about it, and the more we know the better chance we have to slow it down. One still-unknown factor: How might clouds play a part? There's a small hope that they could buy us some time to fix things ... or they could make global warming worse. Climate scientist Kate Marvel takes us through the science of clouds and what it might take for Earth to break its own fever. Check out more TED talks: http://www.ted.com

Legendary ocean researcher Sylvia Earle shares astonishing images of the ocean -- and shocking stats about its rapid decline -- as she makes her TED Prize wish: that we will join her in protecting the vital blue heart of the planet.
The Other Inconvenient Truth: How Agriculture is Changing the Face of Our Planet
We typically think of climate change as the biggest environmental issue we face today. But maybe it's not? In this presentation, Jonathan Foley shows how agriculture and land use are maybe a bigger culprit in the global environment, and could grow even larger as we look to feed over 9 billion people in the future.
Have we used up all our resources? Have we filled up all the livable space on Earth? Paul Gilding suggests we have, and the possibility of devastating consequences, in a talk that's equal parts terrifying and, oddly, hopeful.

If you're lucky enough to live without want, it's a natural impulse to help others in need. But, asks philosopher Peter Singer, what's the most effective way to give charitably? He talks through some surprising thought experiments to help you balance emotion and practicality -- and make the biggest impact with whatever you can share.
As the world faces recession, climate change, inequity and more, Tim Jackson delivers a piercing challenge to established economic principles, explaining how we might stop feeding the crises and start investing in our future.
In a short, funny, data-packed talk at TED U, Catherine Mohr walks through all the geeky decisions she made when building a green new house - looking at real energy numbers, not hype. What choices matter most?
Not the ones you think.
Rob Hopkins reminds us that the oil our world depends on is steadily running out. He proposes a unique solution to this problem -- the Transition response, where we prepare ourselves for life without oil and sacrifice our luxuries to build systems and communities that are completely independent of fossil fuels.
Brilliant presentation of the one and only Johan Rockström.
From 2010 till now we continue to talk one and the same thing. “The key is a shift in the mindsets. We need nothing but a green revolution.”
Human growth has strained the Earth's resources, but as Johan Rockström reminds us, our advances also give us the science to recognize this and change behavior. His research has found nine "planetary boundaries" that can guide us in protecting our planet's many overlapping ecosystems.
In her presentation, Bea shares her tribulations and secrets to achieving Zero Waste. She covers the importance of applying her 5R's in order (Refuse, Reduce, Reuse, Recycle, Rot) and shatters misconceptions, proving that the Zero Waste lifestyle can not only be "stylish", but also lead to significant health benefits, and time and money savings. She brings an intimidating topic down to a manageable scale, lending a unique perspective and making Zero Waste less daunting. Bea talks about her lifestyle with passion and provides many practical solutions to living simply and reducing waste, but more importantly, finding happiness in our consumerist society.
