Plankton population declining

Over the past 30 years researchers have noticed that phytoplankton numbers have declined significantly. According to science news, the phytoplankton has been declining by about 1% of the global average per year. This will eventually effect how we humans live greatly. The food chain begins with plankton and branches off to many other animals. If the plankton were taken out of the food chain, the animals that consume the plankton would not be able to survive leaving a large gap in the chain that would effect all the other animals.

 

The phytoplankton do not only form the base of the marine food web, but they also play a very important role in our lives. Phytoplankton produce close to half the oxygen on earth and remove more than a third of the CO2 from the atmosphere during photosynthesis. If you think about it, if all the phytoplankton were removed we would lose 50% of the oxygen we breathe everyday. Its scary to think about.
