Which situation could decrease the carrying capacity for humans in a certain region?

A situation that could decrease the carrying capacity for humans in a certain region could be a natural disaster such as a hurricane, earthquake, or drought.

Step 1: Understanding Carrying Capacity Carrying capacity refers to the maximum number of individuals of a particular species that a particular environment can support. For humans, this would involve factors such as available resources like food, water, and space, as well as social and economic factors.

Step 2: Identifying Factors that Decrease Carrying Capacity Any situation that significantly reduces the availability of necessary resources can decrease carrying capacity. Natural disasters can cause such a decrease.

Step 3: Example of a Decreasing Situation For instance, a hurricane or earthquake can destroy homes and infrastructure, reducing the amount of livable space and making it harder for people to access food and clean water. This would decrease the carrying capacity for humans in that region.

Step 4: Another Example of a Decreasing Situation Similarly, a severe drought could decrease the availability of water and make it harder to grow food, again decreasing the carrying capacity.

In conclusion, any situation that reduces the availability of resources necessary for human life can decrease the carrying capacity for humans in a certain region.
