Is overpopulation real? Is Earth filling up with too many humans? How many people can Earth hold, anyway? As our species approaches 8 billion, human overpopulation is a major concern for many people. How can we reduce poverty and our impact on the environment? Do we need a forced one-child policy or something? Maybe not, because when we look at the science and history, populations seem to control themselves. This week we look at all these questions and more.

Thanks a lot to Brilliant for supporting this channel.

Finding alien life on a distant planet would be amazing news – or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

Bigger isn’t better (when it comes to energy) | Heather Smith | TEDxAdelaide

Is our energy system doing the job it’s meant to do? As renewables flood into our electricity market, is it driving change in the right direction?

Heather Smith argues that energy should serve our communities. As we get better at using sunshine – an energy resource that is distributed everywhere – we need to build a system that makes sure our energy use benefits everyone.
Heather is an engineer and energy specialist who has spent her career working with energy users and policy makers. She is also a Churchill Fellow and had the opportunity to see first hand the community energy systems and energy transitions that are making news around the world.

Cool airports: innovation for a warming world | Greg Ingleton | TEDxAdelaide

As his flight came in to land, Greg Ingleton was struck by how simple it could be to turn the dry, flat areas of Adelaide Airport into green space. What he then designed turned into something much more powerful, creating new business models in irrigation, agriculture, food service, carbon trading and, best of all, a way to cool airports in the driest parts of our warming world.
Greg Ingleton is an environmental scientist who challenges the way we think about and use water, especially in Australia, one of the driest places on our planet. Part of Greg’s work for a large water utility is to identify and develop opportunities to use ‘wastewater’ in ways that provide social, environmental and economic benefits.

Flightless and fearless: Ostriches can save the world | Andrea Romero | TEDxABQ

Living dinosaurs—or, ostriches—walk the earth as some of the healthiest, most sustainable and valuable resources producing animal on earth. Ostriches compete for the greatest immune system on earth, best steak producing animal, best plumage, best leather — the list goes on. They also produce the largest egg on earth, are the largest bird on earth, never digs its head in the sand, has an eyeball bigger than its brain, are the fastest bipedal runner on earth, and so much more. We’re welcoming these incredible animals presence to New Mexico to showcase their endless potential and are bringing their products to market through Tall Foods. Why raise anything else when you can raise ostrich? Andrea Romero has an obsession for fundamentals, looking to dinosaurs—ahem, ostriches—to help bring sustainable meat proteins to the market by raising desert birds in the high desert of New Mexico to fight climate change from factory farmed meat and find a food secure future in delicious ostrich meats. A business consultant during the standard workweek, this weekend ranchera loves to get amongst it, working with entrepreneurs, community leaders, policy-makers, dreamers, and go-getters. A Santa Fe native, she traveled the world, living in California (Stanford alumni), Mozambique, and Washington, DC. She’s back in NM to build businesses and make as much positive social impact as possible.

3 thoughtful ways to conserve water | Lana Mazahreh

According to the UN, nearly one in three people worldwide live in a country facing a water crisis, and less than five percent of the world lives in a country that has more water today than it did 20 years ago. Lana Mazahreh grew up in Jordan, a state that has experienced absolute water scarcity since 1973, where she learned how to conserve water as soon as she was old enough to learn how to write her name. In this practical talk, she shares three lessons from water-poor countries on how to save water and address what’s fast becoming a global crisis.

Global Warming: Join the Fight with Me! | Ginevra Lapi | TEDxYouth@ISF

We are the generation that was inculcated with terms like “climate change,” “enhanced greenhouse effect,” “high carbon dioxide levels,” but wasn’t given the appropriate tools to solve this environmental crisis. Ginevra explains how she created her own mechanism to use less electricity in her home. She strongly highlights that if she can combat climate change in her own way, she knows that each and every one of us can too. Ginevra was born in Florence to Italian parents and has studied at the International School of Florence since 2011. She is planning on pursuing a Bachelor’s degree in Environmental Sciences at university.

The next generation of African architects and designers | Christian Benimana

Christian Benimana wants to build a network of architects who can help Africa’s booming cities flourish in sustainable, equitable ways — balancing growth with values that are uniquely African. From Nigeria to Burkina Faso and beyond, he shares examples of architecture bringing communities together. A pan-African movement of architects, designers and engineers on the continent and in diaspora are learning from and inspiring each other, and Benimana invites us to imagine future African cities as the most resilient, socially inclusive places on earth.
