About nine million species of animals and plants are exposed to changes in the global climate. Monitoring how climate change affects wildlife and ecosystems has become critical for directing conservation measures where life is most at risk. Today the world's biggest iceberg is bearing down on South Georgia. The Antarctic ice giant, similar in size to the island or to the county of Somerset, is expected to anchor itself offshore of the wildlife haven; posing a grave threat to local penguins and seals. Their normal foraging routes could be blocked, preventing them from feeding their young properly. All creatures living on the seafloor would be crushed where it touches ground. David Attenborough said the world is a unique and spectacular landscape, if we act now we can put it right and save and protect the animals and plants we have endangered throughout centuries of changing the natural world.
