<h3>Formal population education is designed to teach children in school about basic population issues and, in many cases, to encourage them eventually to have smaller families. Some programs include specific units on human reproduction and family planning, while others do not. National population education programs began during the 1970s in about a dozen countries, mainly in Asia. These include Bangladesh, India, Indonesia, South Korea, Malaysia, the Philippines, Sierra Leone, Sri Lanka, Singapore, Thailand, Egypt, Tunisia, and El Salvador. A strong case can be made for including an important contemporary issue like population in the school curriculum. Nevertheless, educational innovation is a difficult and long-term process. As a rule, it takes 5 to 10 years before new material can be fully incorporated in a school curriculum. Curriculum changes must be carefully planned, thousands of teachers trained, and appropriate materials prepared for classroom use. Moreover, differences of opinion over the need, acceptability, goals, content, methods, and other aspects of population education have held back programs in some countries. Where population education programs have been implemented, student knowledge of population issues increases, but it is not yet clear whether in-school education has a measurable impact on fertility-related attitudes or behavior.</h3>

Answer:
The correct answer is synergism.
Explanation:
In synergism, two or more substances interact with each other and produce a greater combined effect than the sum of the effect produced by them separately. So in synergism two chemicals enhance their overall effect when works together. For example, when a cancer patient is given chemotherapy and radiation together it shows better results than when these two therapy are used separately.
So, in this case, X and Y chemicals individually have a limited effect on fish but when used together their combined effect becomes greater which becomes toxic to the fishes that show that it is an example of synergism.

Explanation:
Public health can be described as the procedures taken to protect and improve the health of people and communities.
Public health can be promoted by making people more concerned about having a healthy lifestyle, preventing injuries and preventing the spread of infectious agents.
Public health is not specific to a special group rather it tries to focus on every individual of a population. This population might be a small community or the whole country.
