He doesn’t surf, he doesn’t code, but he’s hacking surfboard fins to combat climate change and it’s working. Meet Andy Stern, citizen scientist and founder of Smartfin. He's brought together surfers and oceanographers to create a smart surfboard fin that's collecting vital data to track and fight climate change.

As far as oceans go, the environmental crisis doesn't just affect the icebergs - it affects all of us. Surfers are on the front lines; as ocean temperatures rise due to global warming, tides and wave characteristics can change. This dilemma helped motivate surfer and oceanographer Phil Bresnahan, lead development engineer at the Scripps Institution of Oceanography, to help Andy develop an electronic surfboard fin that could track temperature, motion and more. They partnered with surfboard fin maker Futures Fins to produce one that performed as well as any high-quality surfboard fin. They also joined up with Surfrider Foundation, a community of everyday people dedicated to protecting the ocean, waves, and beaches got onboard. With their efforts combined, hundreds of surfers around the world are providing valuable sea surface temperature and wave data near coastlines that could be affected by sea level rise.

It’s been the ultimate futuristic dream for decades: flying cars! But now, the future finally has a deadline. At least to start, it will land in the form of a small air taxi operated by Uber, not something you’ll park in your garage.

Paving the Way With Recycled Roads
The world is facing a massive build up of waste. But this solution of recycled roads may pave the way for a cleaner future.

A recycled road has been paved with asphalt that contains the equivalent of hundreds of thousands of plastic bags, along with thousands of glass bottles and printer cartridges’ worth of waste toner. In addition to the sheer amount of recycled materials the process will divert away from landfills, these longer-lasting roads also help to reduce the carbon footprint of construction.

In a new Freethink original series, Michael O'Shea goes around the world to introduce us to the scientists who are working hard to ensure that we can feed our future world.

There are currently over 7 billion human beings alive on Earth --- and in 2050 the world's population will rise by almost 2 billion. That's a lot more mouths to feed considering that roughly 11 percent of the world goes hungry today. "in the next 40 years, we need to produce the same amount of food as we did over the last 8,000 years." Ernst van den...
