In two or three well-developed paragraphs, list and explain at least three changes to the environment that can lead to the spread of infectious diseases.

Changes in the environment can eventually impact the lives in it, and some of these changes would result in the spread of infectious diseases. One is the overuse of the natural resources we have. As a result, we experience scarcity, thus resulting in different kinds of pollution. With pollution around, this increases the risk of acquiring infectious diseases. Hope this helps.

General happiness with the work you do
