How can you prevent a city from polluting a lake? Best answer gets thanks, and 5 star vote!^^

- the city can use reusable water bottles for less plastic and same with other packaging they can use beeswax etc
- wash your car in the grass instead of the road/ driveway for less chemicals going into the storm drain
- recycle, have a compost pile to decompose leaves, food, yard clippings etc and use for soil
