After viewing this video, there is a sudden surge of hope for:
- More design based on nature to increase efficiency (up to 100x)
- A more closed loop system: nothing goes to waste, all by products is fed into another system
- The integration of sea greenhouse, solar tower and greenhouse to create an optimize ecosystem.
Besides depending on superb design and technological breakthrough (which might be out of the reach of most people), I think we should at least have a more efficient waste management system: stop everything from going into the landfill, think of various ways to use them. Example are bio-composition of food waste to generate power, worms for fish food and fertilizer.
