The biodiversity paper states that we can help protect biodiversity by doing all of the following EXCEPT: 1. Protecting insects which play a crucial role in preying on pests and serve as food for those higher on the food chain than them 2. Promoting ecotourism so wildlife is worth more than alive 3. Eating a lower proportion of plant foods than animal foods 4. Taking care not to introduce invasive species 5. Slowing the rate of removal of water from rivers and lakes for irrigation and human...
