Sydney Opera House has been lit up red to mark World AIDS Day on December the first. The stunt was followed by a fireworks display. Observed worldwide, it’s become a day when people are able to come together to remember those who have died from AIDS and is also a time to recognize the progress that’s been made to help end the disease.
