Environmental change and disease dynamics

Abstract

I will start by taking a quick look at the natural ecosystem. A natural ecosystem is a community where the biotic and abiotic components interact together as a unit through biological, physical and chemical processes. Among these components exists a delicate balance, which from time to time may be altered by natural causes (floods, droughts, wild fires, earthquakes, etc.) or by anthropogenic activities (including deforestation, agriculture, pollution, urbanization, etc.).
