Okay, so you know how sometimes we buy things that we maybe shouldn't have, like too much candy or toys we don't really need? Well, sometimes big groups of people like the government can buy things that aren't very good for the planet, like fossil fuels.
Fossil fuels are things like coal, oil, and gas, and they can be dangerous to use because they create a lot of pollution and make the air dirty. So some people in Australia have been talking about not buying these kinds of things anymore, and instead using more clean and renewable energy like the sun and the wind.
What they're doing is called fossil fuel divestment, which means not investing money in those kinds of things anymore. It's kind of like saying, "I don't want to give my money to these things because they're not good for the Earth."
And the government in Australia is thinking about doing this too. They're talking about not buying any more fossil fuels and instead using more clean energy. This will help keep the air clean and make the Earth a better place for all of us to live.
