Today, marine biodiversity is more endangered by overfishing than by climate change or acidification. But in the long term, the latter will considerably increase their pressure. The FAO estimates that between 660 and 820 million people worldwide are directly or indirectly dependent on fisheries and aquaculture. That is about 10% of the world's population. | |||

[[En-en adult card 1 human activities|Human activities]] Through this link, we express all the degradations that Man is capable of inflicting on marine life, such as plastic pollution and overfishing. This is irrelevant in relation to climate change, but it is interesting to make the link anyway. If we are talking to an older audience, we can for example talk about the size of sardine cans, which has decreased because they don't even have time to grow before they are fished. | |||

=== Direct impact of human activities === | |||
Overfishing is the main cause of fish death. Here are some numbers: | |||
* Every year, between 1000 and 2700 billion fish are caught<ref>[http://fishcount.org.uk/studydatascreens/2016/fishcount_estimates_list.php ''Fishcount estimates of numbers of individuals killed in (FAO) reported fishery production'', FishCount]</ref>. If humans were killed at the same rate, it would take only 37 hours to exterminate the human population. | |||
* Plastic pollution kills 1.5 million marine animals<ref>[https://conserveturtles.org/information-sea-turtles-threats-marine-debris/ ''Information About Sea Turtles: Threats from Marine Debris'', Sea turtle Conservacy]</ref>, or 0.0001% of all fishing-related deaths. | |||
