Bren Smith

At a time when the oceans are being ravaged by the effects of climate change and overfishing, Bren Smith is fighting back. The executive director and co-founder of GreenWave has been a commercial fisherman for his whole life, and he is now at the forefront of a movement to make ocean farming a fully green pursuit. Smith pioneered the 3D ocean farming technique, and GreenWave itself is on a mission to mitigate climate change, restore ecosystems and build a blue-green economy. This is the exact kind of initiative that is needed if we want to safeguard the future of the oceans.
