The correct answer is D. Food security is closely linked to poverty reduction, sustainable agriculture, and public health.
Poverty reduction: People who are poor are more likely to be food insecure. This is because they may not have enough money to buy food, or they may not have access to healthy food. Food insecurity can lead to malnutrition, which can make it difficult for people to work and learn.
Sustainable agriculture: Sustainable agriculture is a type of agriculture that uses methods that are environmentally friendly and that can be maintained over the long term. Sustainable agriculture can help to reduce poverty by providing people with jobs and by increasing the availability of food. It can also help to improve public health by reducing the use of pesticides and fertilizers.
Public health: Public health is the science and practice of protecting and improving the health of a population. Food security is important for public health because it helps to ensure that people have access to the nutrients they need to stay healthy. Food insecurity can lead to malnutrition, which can increase the risk of diseases such as obesity, heart disease, and diabetes.
In conclusion, food security is closely linked to poverty reduction, sustainable agriculture, and public health. By addressing these issues, we can help to improve the lives of people around the world.
