Bushfires in Australia have consumed about 100,000 square kilometers, leaving at least 28 people dead and destroying more than 2,000 homes since September. Environmentalists worry the disaster could drive some animal species closer to extinction. A search and rescue mission for thousands of animals caught in the devastating blaze is under way. Efforts to help wildlife in Australia has received international support, with the world's tallest tower in Dubai lighting up with the statement "We can all help" and the hashtag MatesHelpMates.
