Millions of people around the world eat octopus.
In Asia, it is widely consumed in China, Japan and South Korea.
It also considered a delicacy in Mediterranean countries like Spain and Italy.
Every year, about 350,000 tons of these sea creatures are caught.
To keep up with the rising global demand, some countries are farming octopus.
But according to the World Economic Forum, doing this is unethical and can even hurt the environment.
Scientists say octopuses are the most intelligent invertebrates on the planet.
They can solve complex problems and are known for escaping from fishing boats and tanks.
Octopuses can also recognize people’s faces.
They are naturally curious and keeping them in tanks and pens makes it hard because of the small space that would interest them.
If you grow an octopus away from the sea, you need to feed it with three times its weight.
The diet needed should be rich in fish oils and protein giving pressure on already depleted fish stocks.
The World Economic Forum adds farmed octopus also suffer from high rates of infection and have high mortality rate when reared intensively.
Given these facts, should octopus farming continue?
