Summary:

- The article discusses the importance of whale migration and the role they play in the global ocean ecosystem. Whales act as a "conveyor belt" by transporting nutrients and energy across vast distances as they migrate.

- Whale feces and carcasses provide vital nutrients that support phytoplankton and other marine life, helping to sustain the productivity of the oceans. This "whale pump" effect has a significant impact on global carbon cycling and climate.

- The article emphasizes the need to protect whales and their migratory patterns to maintain the delicate balance of the ocean ecosystem. Conserving whales is crucial for the overall health and resilience of the marine environment.
