Locals discovered a massive fish die off on Mallacoota beaches; thousands of fish were counted along with numerous sea urchins and some penguins.
- An upwelling causes a decrease in oxygen level in the water and creates toxins, these factors can cause a kill offs.
- Changes to the East Australian Current (EAC) contributed to a stronger than usual upwelling, the EAC runs further south than it used to and is more intense.
- The East Australian Current has extended 350kms south since the 1940s.
What can be done?
- Email your local MP and tell them that action on climate is important to you and explain the impacts being felt in your area. One email might not feel like much but most politicians consider it to be representative of 100 citizens.
- Help support the Act on Climate collective by donating; we are leading the charge for climate action. Your donation helps in advancing policies that prevent climate change from getting worse, we aim to empower communities and build a strong pro-climate-action constituency that governments can’t ignore, and as an added bonus it’s tax-deductable.
- Get involved with Act on Climate. We meet every Monday at 6pm (upstairs at 312 Smith St, Collingwood) and welcome all newcomers to join in the fight for climate justice. If you are unable to attend, follow us on Facebook, Twitter and Instagram to keep up with the latest campaign.
