Between the scientific community, governments, humanitarian organizations, and even military planners, climate change is considered to be the single greatest threat facing humanity today. Between the increases in famine, disease, flooding, displacement, extreme weather, and chaos that result, it is clear that the way we are causing our planet to get warmer is having dire consequences.
“The oceans cover 70% of the surface of our planet, and yet they are still the least explored,” says Sir David Attenborough in the opening sequence of the recent BBC documentary series Blue Planet II. “Hidden beneath the waves, there are creatures beyond our imagination.” Yet while the programme reveals the wonders of many of these species, an incredible number more have never been encountered by humans at all.
Seafood is an essential staple in the diets of people around the world. Global consumption of fish and shellfish has more than doubled over the last 50 years, and is expected to keep rising with global population growth. Many people assume that most seafood is something that we catch in the wild with lines, trawls and traps. In fact, aquaculture (aquatic farming) accounts for just over half of all the seafood consumed worldwide.
