Answer 1

Hint: It arises when the population of a species exceeds the carrying capacity of its ecological niche. Rises in birth rates (fertility rates), decreases in mortality rates, rises in immigration or unsustainable biomes, and depletion of resources may result.

Complete answer:
Individuals restrict available resources to survive as overpopulation arises. An essential variable that has a major influence on the entire environment is the change in the number of individuals per unit area in a given locality.
Human overpopulation happens when the number of people exceeds the carrying capacity of the position occupied by that group in a particular geographical area. Overpopulation can also be seen as existing in the long term when a population cannot be maintained due to the rapid depletion of non-renewable resources or the degradation of the environmental capacity to provide support to the population.

Additional Information:
Obesity is a dynamic disorder that requires an unhealthy amount of body fat. Obesity isn't only a cosmetic issue. It is a medical issue that increases the risk of other conditions and health problems, such as heart disease, diabetes, high blood pressure and certain cancers.
An unbalanced or imbalanced diet is one that consists of the basic components of a safe and nutritious diet, including too much or too little protein, fats, carbohydrates, fiber, vitamins, minerals, and fluids.
A lack of reading and writing ability. The condition of being illiterate; absence of any or sufficient education. An error felt to be characteristic of an illiterate or semi-literate person in writing or speaking: a letter full of illiteracy.
So, the correct answer is ‘Overpopulation’

Note: The term human overpopulation also refers to the relationship between the human population as a whole and its environment: the Earth, or countries such as smaller geographic areas. Increases in birth rates decrease mortality rates against the backdrop of high fertility rates, increases in immigration or unsustainable biomes, and depletion of resources which lead to overpopulation.
