Glacier melting is a current issue in our environment and needs to be urgently addressed. It is happening as a result of global warming from our increasing carbon emissions. There is a hole in the ozone so the iced caps are exposed to more sun and are melting quicker. It’s causing habitat destruction for polar bears and other Arctic species. As well, sea levels are rising and eventually most of our shoreline cities will be under water. Unless we can drastically reduce our greenhouse gas emissions this will continue.
