a passionate person who focuses on the ocean.
he has been going to pristine coral reefs to get a better understanding of their function.
Christmas Island is the largest coral island. when captiain cook discovered the lagoon, there were thousends of sharks and today there are none. the coral reef is covered with algae and is essntially dead.
he went on to show three others that were better condition. endig with Kingman Reef
in a pristine reef, the food chain is inverted. the top predators make up most of the biomass and herbavoirs the least.
how have we killed coral reefs?
1. removed everything big and reduced biomass
2. inverted the biomass
3. replacing corals with seaweed
4. enhancing microbial explosions
5. reduced resilience
another wow.
