Animal Agriculture & Water

This is the part two of a multi-article series on the connection between animal agriculture and various societal and environmental problems. This article covers animal agriculture’s connection to freshwater use, freshwater quality, water pollution violations, fishes and other sea animals, ocean hypoxia, and declining phytoplankton in the oceans.

Algae Blooms In Lakes & Oceans Creating Pollution That Harms People, Pets, & The Planet

Aquatic ecologist John A. Downing happily remembers childhood holidays at his family’s vacation home at Wabana Lake, near Grand Rapids, Minnesota. The lake was upstream “from almost everything,” making it difficult for pollution to reach it, he said. But some eventually got there anyway. “It’s still beautiful, but somewhat greener around the edges,” he said. “I have been diving in these lakes since I was 9 years old, and as I get older, I notice there are more frequent surface algae blooms.”

Growing Algae, Saving Energy, & Capturing Carbon: P2P Microalgae Technology

Microalgae are single-celled organisms that are normally found in freshwater systems. This versatile plant matter can be used to produce biofuels, medicine, vitamin supplements, cosmetics, and feed for livestock. Microalgae is also a natural decontaminator, removing toxins from wastewater and absorbing carbon dioxide and other greenhouse gases from the air. A new innovation at Grande Prairie Regional College (GPRC) in Alberta, Canada, cultivates microalgae using sunlight energy.
