Fluorescent Light Disposal
The mercury from ONE fluorescent tube can pollute 30,000 litres of water beyond a safe level from drinking. Mercury is a deadly poison. Chronic exposure leads to brain damage. Mercury easily gets into water, then into fish, then back into humans. Mercury containing products of any source must be disposed/recycled properly. Older wall-mounted thermostats have a ball of shiny silvery liquid metal mercury. Thermometers with a silver column (not red) probably contain mercury.
