no arguments. But I'm asking what effect whaling has on
the stability of the climate.
Most of the large whales feed on krill. Krill feeds on
phytoplankton that bloom in cold water if there is the
correct combination of nutrients and sunlight.
Fertilizer is essential to plant growth and the reduction
in both the species and numbers of whales, has limited the
available nutrients; whale shit being an important part of
the food chain.
With reduced plankton populations, the solar energy heats
the seawater at a greater depth than normal.
But isn't that made up by nutrients in the run-off from
intensive Western farming? If memory serves, I saw this
reason cited as one of the major causes of the death of the
Great Barrier Reef.
