Bushfires have been blazing in Australia since September, and they’ve intensified this week to “apocalyptic” levels, as more than 15.6 million acres have burned so far. The fires have killed at least 25 people and destroyed 2,000 homes. Experts also estimate that over 1 billion animals have died since the fires began in September. If you’re having trouble visualizing the scope of these fires, here’s a comparison using a map of the US. Officials say that the fires may burn for months.
