Water covers around seventy percent of the Earth’s surface. However, since prehistoric times, the main way of producing food is land-based, both by agriculture and by cattle farming. However, we should not forget that the oceans also provide a significant portion of food. The only problem is, there aren’t as many fish in the oceans as there used to be.
What seems to be the problem?
The highest number of fish in the oceans, as scientists point out, was some thirty years ago. Since then, it has decreased, meaning that there is a danger for fish markets all over the world if nothing is done. Also, with the world’s population rising steadily, there will be more demand for food in the years to come, so we need a solution that will put an end to this problem.
How can we fix this?
Compared to land farming, water farming, also known as aquaculture, is a relatively new concept, although some countries around the world have already implemented it successfully. It revolves around the concept that a more careful approach should be taken towards water creatures that we use to sustain ourselves, so as not to eradicate them completely.
What does aquaculture include?
Although, when we first think about sea life, we probably think of fish, there are plenty of organisms that can be farmed in water. Fish is the most obvious choice, and some Asian countries such as China and Vietnam have already started farming their fish successfully. Of course, there are countless other sea creatures that can be farmed, and mussels are probably one of the most interesting to mention. Not only are they easy to farm because they do not require any food, but they also, alongside clams and oysters, help purify the water they inhabit, which has obvious benefits in the time when the pollution of the oceans poses a great threat to both humans and animals. Plants are also successfully farmed in the ocean water; some Caribbean islands are speculated to be able to safely harvest 25 million tons of algae per year, which can be used for both human and animal consumption.
Are there any downsides to this?
Due to the fact that this is still a relatively new area in food production compared to land-based food production, it is still a bit underdeveloped, and a cost of running such a farming business is still a bit high. However, we oughtn’t let that discourage us from developing this system of food production, as it is not only more healthy for the environment, but the development of this branch of the food industry would also create many new working positions that may ease the unemployment problem young people all over the world are faced with. To sum up, even though it is a relatively young concept, aquaculture is a promising idea that would not only benefit the people involved, but it would also be good for the environment.
