What are some of the changes that have occurred in the past 50 years that have led us to now take 80 to 90 million metric tons of fish out of the sea every year?

Respuesta :

Answer: We created more effective and superior fishing methods. In addition, our population has increased, meaning there are more people to eat fish.

Over the past 50 years, the production of fish and seafood has doubled worldwide. In addition to the fact that the world's population has more than doubled during this time, the average person now consumes about twice as much seafood as they did fifty years ago. Fish stocks all across the world are under more strain as a result of this. Since the 1980s, the proportion of fish populations that are overexploited globally—meaning that humans harvest them more quickly than they can reproduce to maintain population levels—has more than doubled, making the current levels of wild fishing unsustainable.
