Australia's biggest environment problem is ignorance. As a culture, we're all about the "quick fix"; getting things done in a "fast" and "convenient" way. But in that thinking, we're using products that are harmful to our marine life such as plastics in the oceans. We're using the convenience of driving when we could save our carbon emissions by walking or taking public transport to have less cars on the road. Using less water when doing the dishes or brushing our teeth. Ignorance is our biggest problem, and we all need to be properly educated.
