The document discusses several ways that human activities harm bodies of water. It notes that oceans cover 71% of the earth's surface and are home to thousands of species, but they are used as global garbage cans with millions of chemicals dumped in annually. Specific harms discussed include offshore drilling releasing contaminated water, oil spills which often go unreported, overfishing causing species depletion, and commercial fishing methods that destroy habitats. Cruise ships and untreated waste also contribute to water pollution. The document advocates for eliminating straight pipes, regulating bycatch and overfishing, preventing oil spills, and conserving fresh water usage to help protect bodies of water.
