What Song Does Lost In The Woods Sound Like, The plastic-to-water ratio in the study would only be seen in severely polluted places, but the findings raise questions about the wider impact of plastic contaminants on marine life. A trophic cascade occurs when removal of one species (usually a predator) affects the abundance and distribution of species that it does not directly prey upon. Generally, the higher the environmental temperature, the faster the embryo divided. Thus, observation of successful fertilization and the subsequent embryonic development of sea urchin eggs can be used as a convenient biosensor to assess the quality of the marine environment. Fortunately, sea otters have an appetite for sea urchins and they help to keep sea urchins in check, allowing the kelp to flourish and capture CO 2. These urchins developed normally, suggesting that abnormalities observed in other samples were caused by industrial additives and/or environmentally adsorbed contaminants -- rather than the base plastics themselves.
