What is the Importance of The Carbon Cycle?

What is the importance of the earth's Carbon Cycle, and how does commercial whaling affect it?

• For a persuasive speech I'm arguing the topic of commercial whaling, and one of my reasons for being against it is going to be the effect it has on the earth's carbon cycle. What is the importance of the carbon cycle, and what would it mean for it to be affected negatively? And how does commercial whaling affect the carbon cycle? Thanks in advance ^^

• Answer:

  The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. It is one of the most important cycles of the earth and allows for carbon to be recycled and reused throughout the biosphere and all of its organisms. Whale droppings is vital to ocean’s carbon cycle Saving endangered baleen whales could boost the carbon storage capacity of the Southern Ocean, suggests a new study of whale feces. Whale feces once provided huge quantities of iron to a now anaemic Southern Ocean, boosting the growth of carbon-sequestering phytoplankton.
