Oceans Lab
Part 1
Over fishing lead to the Sea Urchin
dying, and also lead to the collapse of the cod. Cod was once a great
and tasty but now it is a small and cheap fish thanks to over fishing. Industrial
Fishing leads to trawling, which then leads to habitat
destruction, which is what the continental shelves of the world look
like. Magnitude shifts lead to, two kinds of biological pollution. One
is caulerpa toxifolia, and the
other is nitrogen fertilizer, which feeds plankton. Because there
is nothing to eat the plankton they die off and create bacteria in the ocean,
which leads to only jellyfish in that area. Another problem is toxic
bloom; it took over the Mississippi Delta and the Northwestern
Gulf of Mexico at one point and lead to toxic dinflagellate, which
kills fish and harms humans. The coast of Brittany is overrun by it, which has
led to sea birds flying over and being asphyxiated by the smell
and dying. Climate change and warmer oceans lead to coral reef
bleaching which leads to algae and reefs dying. This then leads to Positive
feedback and Synergy, which will then lead to Dead zones of
the Global oceans.
