* Over 3 billion people: This is the estimated number of people who rely on fish as a major source of protein, according to the Food and Agriculture Organization of the United Nations (FAO).
* High concentration in developing countries: The reliance on fish for protein is especially high in many developing countries, particularly those with coastal populations. For example, in some parts of Africa, Southeast Asia, and the Pacific Islands, fish can account for over 50% of animal protein intake.
Factors influencing these numbers:
* Accessibility: Fish is often more accessible and affordable than other protein sources in coastal areas.
* Cultural significance: Fish is a traditional staple food in many cultures.
* Environmental factors: Overfishing and climate change threaten fish populations and impact the availability of this vital protein source.
Conclusion:
While an exact number is hard to pinpoint, it's clear that millions, if not billions, of people rely on fish for their primary protein source. This dependence is significant and highlights the importance of sustainable fishing practices to ensure food security for these populations.
