Experts know the ecological importance of whales an important prerequisite for forecasts of change in polar ecosystems in the context of global climate change.
Scientists found that whales also improve the food cycle for fish and drive their reproduction. Thus, where whales are present, conservation of stocks is guaranteed.
Even though the polar regions are among the most inhospitable areas on our planet, the largest marine animals live there. However, the reason for the large number of whales and seals in the Arctic & Antarctic lies not only in the seemingly inexhaustible abundance of food such as krill, a type of crab, which is found in immense quantities, but above all in the hostility to humans. The giants of the animal world survived longest in the regions of the earth inaccessible to humans.
Their future is our future.
- Whales feed on krill and fish
in the depths of the oceans.
- For their excrements they come
to the surface of the sea. There live
microscopic plants,
the so-called phytoplankton.
The excrement of the whales is an
important fertilizer for the phytoplankton.
- More whale excrement means
more phytoplankton. Phytoplankton
converts sunlight into energy
sunlight into energy and
oxygen. It produces at least
half of the oxygen in our
atmosphere and, with the help of
whales thus has a positive effect on
our climate.
