Ecosystem Ecology: Links in the Chain - Crash Course Ecology #7

Equipment too expensive? Build your own. Don't know how? We've already published the schematics, guides and everything else you'd need to build many of the 50 machines needed to build civilisation. Now we are using the same open source philosophy that helped us build these machines to construct houses in 5 days. We hope to solve the housing crisis and train people across the world how to build these homes for themselves or for others! If you want to learn more check out our Builders Crash Course
