Water pollution experts make a clearcut distinction between what is normally considered a naturally occurring chemical in a higher concentration level and a contaminant. Chemicals and pathogens are actually the ones responsible for the waterborne diseases that affect both animals and humans. The fish living in a contaminated area will accumulate toxins in their bodies being afterwards consumed by people. This is the risk chain that the constant and over-growing water pollution has set into motion. Statistics actually indicate that 14,000 people die every day because of water pollution.
