The devastating effects of climate change are everywhere. Now, the fight to save the planet is taking an innovative turn. What if scientists could offset dangerous greenhouse gas levels by capturing CO2 from the atmosphere and putting it to use? This episode looks at two project that aim to capture CO2 and convert it into useable products. The first would combine basalt and CO2. Basalt is naturally highly reactive with CO2; when the two meet, they undergo a series of exchanges that culminate with the carbon precipitating out as a solid whitish substance, similar to limestone. The second project uses cyanobacteria to convert CO2 into bio products such as fuels, bioplastics, oils and flavourings. - Subscribe to our channel: http://aje.io/AJSubscribe - Follow us on Twitter: https://twitter.com/AJEnglish - Find us on Facebook: https://www.facebook.com/aljazeera - Check our website: http://www.aljazeera.com/
