This chapter is about technology in the Anthropocene. Professor Galaz begins with an example of the Titi money from the Amazon, which is used to promote conservation effort. This introduces three issues: biodiversity, politics, and technology. Geo-engineering efforts attempt to use technology to steer away from, mitigate, and adapt to tipping points; Galaz gives examples of these controversial ideas. The precautionary principle states that we shouldn’t do anything that might create harm, which is invoked often in the case of new technologies.
