From sex workers selling nudes in exchange for donations, to volunteer firefighters embarking on the seemingly impossible task of containing the flames, people from across the world are coming together to fight the Australian bushfires, which have left thousands of people evacuated from their homes, while an estimated half a billion animals have been killed.

Among those joining in the effort is Lizzo, who took time out of her Australian tour yesterday (January 8) to help those affected by the crisis. Kitted out in an orange high vis and blue gloves, the “Truth Hurts” singer joined volunteers at a food bank in Melbourne to sort through donations and pack food hampers for those in need.

According to the Food Bank Victoria Instagram account, Lizzo made a speech to the hardworking volunteers who have been working almost non-stop for six days to get food to those most affected by the bushfires.

Among the celebrities donating funds towards the bushfire efforts is Margot Robbie, Elton John, Pink, Russel Crowe, and Chris Hemsworth. Teen activist Greta Thunberg has also condemned the Australian government for not taking enough action in addressing the disaster.

The 17-year-old wrote on Instagram: “Australia is on fire. And the summer there has only just begun. 2019 was a year of record heat and record drought. Today the temperature outside Sydney was 48,9°C. 500 million (!!) animals are estimated dead because of the bushfires.”

She continued: “Over 20 people have died and thousands of homes have burned to ground. The fires have spewed 2/3 of the nations national annual CO2 emissions, according to the Sydney Morning Herald.”

Here’s a breakdown of what you can do to help.
