|Interesting facts | |Did you know? | |Every year approximately 75,000 litres of detergents and 12,000 kilograms of dirt and other pollutants flow into North Shore | |City’s streams, lake and beaches from people washing their cars on the road. | |Fifteen per cent of pollution incidents reported to North Shore City Council are traced to painting activities. | |The chemicals found in one cigarette butt can leach out and contaminate approximately 7.5 litres of water within one hour. This | |contaminated water is lethal to small crustaceans and other aquatic life. | |Concrete washings are arguably the most harmful, yet least recognised pollutant entering our waterways. Thirty per cent of all | |fish kills reported in Auckland streams are due to concrete and cement washwater discharges. | |You would need a large road tanker full of water (approximately 10,000 litres) to neutralise 1 litre of cement slurry. Dilution | |is not the solution, as it only extends the deadly effects further downstream. | |Every year in the Auckland region over 85,000 tonnes of dirt enters our streams, lakes, estuaries and harbours. Sediment can | |kill aquatic organisms just like a chemical can. | |Worldwide, sediment is by volume the biggest single water pollutant. In Auckland, sediment is the largest cause of shellfish | |losses in our estuaries, not chemical spills. | |In a stream entering Lucas Creek, a major sediment discharge wiped out the native trout that then took almost seven years to | |re-establish in the stream. | |Organic substances like food and grass clippings can cause significant adverse effects if allowed enter into a waterway. | |Approximately nine million litres of oil is unaccounted for each year in the Auckland region – which probably means we end up | |swimming and fishing in it! Just 1 litre of oil can cover the surface of 100m2 of water. | |Water that goes down our outside drains flow directly to our streams, Lake Pupuke and beaches without being treated. |

o If just 25% of U.S. families used 10 fewer plastic bags a month, we would save over 2.5 BILLION bags a year. o On the average, the 140 million cars in America are estimated to travel almost 4 billion miles in a day, and according to the Department of Transportation, they use over 200 million gallons of gasoline doing it. o Every year we throw away 24 million tons of leaves and grass. Leaves alone account for 75% of our solid waste in the fall. o Over 100 pesticide ingredients are suspected to cause birth defects, cancer, and gene mutations. o Every ton of recycled office paper saves 380 gallons of oil. o About 1% of U.S. landfill space is full of disposable diapers, which take 500 years to decompose. o Energy saved from one recycled aluminum can will operate a TV set for 3 hours, and is the equivalent to half a can of gasoline. o Glass produced from recycled glass instead of raw materials reduces related air pollution by 20%, and water pollution by 50%. o Americans use 50 million tons of paper annually -- consuming more than 850 million trees. o...
