Our carbon dioxide emissions are making the oceans more acidic. As we pump carbon dioxide into the atmosphere, a portion dissolves into the world’s oceans. Once there, the carbon dioxide goes through a series of chemical changes that have an acidifying effect on seawater. Trees absorb carbon dioxide from the air and through photosynthesis. Underwater
Hartbeespoort Dam in South Africa has a new invasive aquatic weed to battle, Salvinia minima. The proliferation of common salvinia, just as water hyacinth came under biological control through the combined efforts is no coincidence. In areas that experience high levels of nutrient inflow (pollution), the control of one aquatic weed opens resources to other
A public boat launch doesn’t necessarily make access to a lake free. There are costs involved in keeping the waters weed free, navigable for recreation and stocked with fish. McDill Inland Lake Protection and Rehabilitation District’s president Krista Olson asks people visiting any lake to utlize the donation boxes. Those donations are very important for

Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. Many local farm stores keep the product on store shelves helping to make it the most used, and the most economical algae control available for ponds and lakes. Copper Sulfate is ineffective in the
