Impact of Plankton on Ecosystems

The video discusses the vast amount of water on Earth, covering 71% of its surface, and introduces the five oceans. It highlights the critical role of plankton, tiny organisms that are essential for marine ecosystems and human life. Plankton are responsible for a significant portion of photosynthesis and recycling organic matter in the ocean. Their disappearance would lead to the collapse of marine food chains, affecting oceanic megafauna and human economies reliant on marine resources. Plankton also contribute to global oxygen production and the formation of oil and gas reserves. The video emphasizes the importance of conserving plankton to maintain ecological balance and human survival.
