Imagine you and your friends are going on a fishing trip to the ocean. However, you have to make sure you don't take too many fish because there won't be enough left for other people to fish later. That's what the Convention on Fishing and Conservation of Living Resources of the High Seas is all about.
The Convention is an agreement between countries that sets rules for fishing in the international waters outside the jurisdiction of any one particular country. It's like a big agreement that all the countries follow to make sure there are enough fish in the ocean for everyone.
The Convention aims to make sure that fishing is done in a way that doesn't harm the environment and that there are enough fish left for future generations. It also sets rules for how many fish can be caught and how big they need to be before they can be caught. If everyone follows these rules, then the ocean can be a happy and healthy place for fish and people to share.
So, just like how you and your friends need to be careful not to take too many fish on your fishing trip, countries need to be careful not to take too many fish from the ocean. Following the Convention helps keep the ocean healthy and the fish populations sustainable.
