Lakes

Americans use our lakes as a source of recreation, water, and even income. However, these luxuries are at risk when we carelessly release toxins into our lakes. Air pollution, fertilizers, and boat pollution are destroying our lakes at an increasing rate, and most of us aren't doing anything to prevent it.


Fertilizer runoff

When fertilizers are carried into lakes or any other source of water, they bring nitrates and phosphates with them. These nutrients, essential for plant growth, cause plant life and algae to grow at rapid rates. This soon changes oxygen levels, killing other forms of life such as fish. This process is also known as eutrophication.


Boat Pollution


Everybody enjoys a relaxing boat ride once in a while, but many of us don't realize the risks we subject our lakes to when we boat. Boat engines cause a great deal of pollution by emitting hydrocarbons and oxides of nitrogen, but they are not the only source. Careless spillage of gasoline, and the carrying of evasive plants can also destroy waters and ruin the lakes and waterways we hold onto dearly. The only way to prevent these from happening is to start from the source. Be sure to always make sure no gasoline is spilled when filling your tank, and always clean your boat thoroughly before launching into another lake. Many of the problems mentioned, such as the carrying of evasive plants, are irreversible, so please make sure you keep our lakes clean!
