Human Chemical Disturbance

INTRODUCTION

Human disturbance is a measure of how vulnerable aquatic resources are to harmful human activities such as deforestation or landfills + litter. The impacts of these can negatively affect fish, wildlife and other aquatic communities as well as come back to hurt humans in the form of drinking water, etc. 

“Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath” – Nathaniel H. Egleston
