Leaves + water = algae = dead fish
Leaves, grass and pet waste release phosphorus into our lakes and rivers, which feeds algae. When this kind of organic debris isn’t bagged and properly composted, it runs through storm drains and directly into our waterways, turning our clear water green. This depletes the oxygen in the water and makes it hard for fish and other wildlife to survive.
By cleaning up on October 13, Girl Scouts will remove 20,000 pounds of phosphorus, preventing 10 million pounds of algae growth and saving $6 million in cleanup costs.
Did you know?
- Just three percent of the water on earth is fresh water. That means if all the water on earth equaled 100 drops, only three of them would be fresh enough to use.
- The surface of a city block can generate five times more polluted runoff than a wooded area of the same size.
- Storm drains are not connected to water treatment systems. Anything that enters a storm drain flows untreated into the nearest waterway (including the lakes and rivers where you swim and fish).
