Even the rain forest is being threatened, which happens to be natures very own filtration system for removing CO2 from our environment. As the human population grows, so does the need for food, water and energy to sustain life. However, as the last century has taught us, we cannot simply sustain life at the expense of the environment or our planet’s very health. 4 SKIES believes its TRI-GEN-ZERO™ concept offers a solution which allows us to continue to utilize fossil fuels by combining CO2 scrubbing with the natural CO2 sequestration from the vertical farms. The net benefit of this solution is energy and food security, as well as a positive impact on the environment.
