As society exceeds key 'planetary boundaries' many solutions are on the horizon, too
Climate change & loss of biological diversity are just two of the 9 planetary boundaries scientists say humanity is currently pushing the limits of.
How long can we sustain society if we keep pushing these limits?
We explore this question -- and some leading solutions -- with two guests: Dr. Claire Asher is a freelance science communicator and author who joins us to discuss a recent article she wrote for Mongabay that describes the boundaries, the 4 we are already exceeding, and the opportunities we’ll have in 2021 to transform the way we live on this planet and restore equilibrium to Earth’s vital ecological systems, from sustainable design and agriculture to key international meetings.
Then Andrew Willner discusses his recent Mongabay article “New Age of Sail” that would transform the global shipping industry, a major source of CO2 emissions that are shifting the climate. Willner shares how cutting edge technologies are deployed on ships right now to decrease their fuel consumption, including a number of modern types of sails that are once again harnessing the wind to power the ships moving our goods around the world.
