microTERRA develops on-site water-treatment systems that use micro-algae to transform wastewater into a sustainable protein source for the tilapia while cleaning the water. In essence, it turns fish poop into fish food, which requires less changing of water, and thus produces less waste water. There are other residual benefits to this system, as well. All of the SDGs are related, referring to the UN’s Sustainable Development Goals. When we are treating water with micro-algae, the micro-algae is also storing carbon, so it’s a carbon-drawdown solution. And water is a super-important resource, which we are going to have to take care of with the crisis of climate change. So the main source of water we are saving is ground water. When we store more ground water, and stop using as much, the opportunities of adapting to climate change multiply.
