Bigger Is Better

People may not think it, but whales are an extremely important organism in the ocean biome. Due to their immense size, the carbon that is stored within them greatly affect their environment. Humans have impacted the ocean biomes by reducing the abundance of several large marine vertebrates. These marine vertebrates consist of whales, sharks, and other large fish. A major consequence of removing these organisms is the inability to store carbon, due to the significant loss of organisms that could store it in their bodies.

Particularly immense whales that most individuals focus on relating to this topic are baleen whales. Whaling is takes a crucial part in reducing the amount of carbon being stores into whales. Humans will kill the baleen whales, while their carcasses will be left untouched and will sink. After whaling occurred, baleen whale populations store 9.1 X 10^6 tons less carbon. This is a significant decrease in carbon storing, hence making it a noticeable matter in the ocean biomes.

There is a beneficial side to organisms in the ocean biome with whaling, however. With the decrease in baleen whales, crustaceans will increase in population. However, since a shift towards smaller animals have occurred with the absence of several larger predators, this could decrease the total community biomass by 30% or more. With whaling occurring currently, carbon spread is decreased throughout the biome. Whales and other large marine animals can spread carbon while they're alive from the surface throughout the biome, due to their immense size. Overall, whaling produces more problems than it does resolutions.
