Antarctic Sea Ice Retreats, Posing Threat to Krill, Wildlife - Bloomberg
Loss of sea
ice in Antarctica, probably due to rising ocean temperatures, may
be what has caused the 80% drop in krill populations in the southwest
Atlantic over the past 30 years. Changes in the krill population
endanger other species, such as penguins, dependent on them for
food.

The arrival of new species, particularly parasitic ones such as some of these mushrooms, may be the beginning of widespread changes to Scotland's delicate
ecological balance according to experts.

done this summer. This could have, as a side effect, a beneficial
impact on carbon dioxide levels in the atmosphere.
