Many of the whale species are seriously threatened with extinction and many others are at risk. This happens because until the 20th century, predatory whaling was allowed and this caused the death of thousands of individuals around the world.
Whales were hunted at dangerously high levels in the 19th and 20th centuries. The first protections were introduced by the IWC in the 1960s and a ‘moratorium’ on all commercial whaling was implemented in 1986. The recovery of some populations from near extinction is a great conservation success story, but it is certainly not the the case for all, and some populations remain critically endangered.
Antarctic penguin populations are threatened by climate change. This is what the research by the WWF Network, Antarctic Penguins and Climate Change says.
The study shows that four different species of penguins are under increasing threat. For some, global warming shrinks the area needed to care for the young. For others, food becomes increasingly scarce because of rising temperatures and fishing. Antarctica is heating up five times faster than the planet’s warming average. The massive Southern Ocean has been warming up to 3,000 meters deep.
