Question

which of the following is a negative impact of increasing human population growth? increase in number and strength of diseases longer life expectancy for humans stronger economy within different countries improved air quality globally

Explanation:

When human population grows, more people mean more interactions. This can spread diseases easily. Also, overcrowding (due to population growth) can create conditions (like poor sanitation in some cases) that make diseases stronger.

• Longer life expectancy (B) is a positive thing. It shows better healthcare etc., which is good.
• A stronger economy (C) is a positive impact. More people can contribute to work and trade.
• Improved air quality (D) is positive. But population growth usually (without proper measures) leads to more pollution (from more vehicles, industries as population grows) rather than better air quality. So, only A is a negative impact of increasing human population growth.

Answer:

A. increase in number and strength of diseases
