overfishing

The North Atlantic whale, which is critically endangered, will become extinct without immediate action to protect and revive them, according to scientists.

Mercury content - an organic compound that can cause brain damage and severe nervous system - has increased by 23% in cod and 27% in bluefin tuna caught in the Atlantic Ocean.

Thousands of tons of sharks are caught each year and the impact from plastic waste pollution puts the Mediterranean at risk of absence of sharks.

A large bluefin tuna, a rare and abundant fish of many years, has been discovered in the UK.
