Does global warming affect life in the oceans?
Climatic warming affects marine organisms. For example, let’s look at the impact of glacial ice melt. With global warming, glaciers (which are made of ice and snow) melt. In the area where we are, the glaciers are melting twice as fast as they were 13 years ago! And all that melting ice becomes water that runs off into the sea, carrying with it enormous quantities of sediments (debris such as rocks, sand and mud). These sediments are then in the water. They block out light for the algae and settle to the bottom on top of the starfish, marine sponges and other organisms that live on the sea floor. Marine life is thus impoverished, because life is tremendously dependent on the light used by the algae to perform photosynthesis. The warming of the water also causes huge changes in sea currents. And since one of the roles of these currents is to transport the nutritive elements necessary to the life of small organisms (phytoplankton and zooplankton), climatic warming depletes marine life in
