The New year. Thinking about a fitness regime? Stretching before a swim this young polar bear Hamish was born at the Highland Wildlife Park Scotland in December 2017 to Mum Victoria. This picture was taken in May 2018. At the start of a very warm summer in UK. Polar bears are one of the first species to become threatened by climate changes made by humans. They need the presence of sea ice to cover a large area, so they can search for food. Climate change causes sea ice to melt earlier and form later each year, leaving polar bears less time to hunt for food. Pregnant females need to build up fat stores to live off when giving birth and feeding their cubs. Organisations are working hard through research and conservation projects to secure the future for polar bears.
