Not long after agriculture was domesticated, aquaculture emerged. This multi-billion-dollar industry is expanding to meet growing demand. Dominated by Asian countries, aquaculture production threatens Blue Carbon Zones from Chile to Egypt, Australia to Mexico. In Part I of this episode, Jorden and Kimberly consider how aquaculture is a threat to the planet, but can be the key to sustainable freshwater and saltwater food production.
 

Key Topics Jorden and Kimberly discuss include:

• How to save a fishing industry from total collapse


• Why not all farmed fish is spawned equally


• How a Japanese university beat the odds on tuna ranching


• Why the sustainability issues aquaculture faces aren’t far from those for agriculture


• Why aquaculture might be the best way to promote ocean and freshwater conservation
