Internet resource online: 3 blogs and papers on how organisms clean water: I would like to make three points: 1.In these three papers (mentioned in the blog below), the author demonstrated how aquatic invertebrates may contribute to making water clean and clear: https://www.researchgate.net/profile/Sergei_Ostroumov/blog/677_Three_papers_on_filter-feeders_and_their_role_in_ecosystems; 2.In this paper (see the blog below), the same author discovered some new facts on how aquatic plants may contribute to making water clean and removing heavy metals from water: http://blog.researchgate.net/masterblog/594_New_plant_species_as_a_potent_tool_to_clean_water_and_to_remove_heavy_metals; 3.In the opinion paper (see the blog below), the same author integrated various data on plants, animals, and microorganisms toward formulating a new holistic theory of how all organisms interact and benefit each other, and as a community function toward decontaminating water and increasing water quality: http://blog.researchgate.net/masterblog/610_New_unified_theory_of_the_ecological_mechanisms_to_improve_water_quality_and_to_make_water_clear_a_basis_for_water_purification_and_waste_water_treatment;
