If we keep fishing and polluting our oceans like this then, in a few years, there will be no more fish to catch. Then the ocean is nothing more than one big pool of water. We need to protect and conserve it for our future generations. Research is very important in this. We need to set quota to help our fish populations grow again. We need to change our fishing gear to reduce our bycatches. Overfishing is one of the major issues going on at the moment. What if the last fish of a certain species is already caught? How to deal with ‘us’ as humanity? If we succeed to change our behaviour, our oceans will become a major source of food again. The ocean is not only a source of food, it is also a place where people can relax and do their favourite hobbies.
