climate change is the main problem of the world. In the Australia, fish on Australia's east coast are moving to the south with an increase in ocean water temperatures. Scientist says this has resulted in a number of fish species moving south. "It means fish formally confined to Queensland are moving into New South Wales, New South Wales species are migrating to Victoria, and Victorian fish are heading into Tasmanian waters," he says. 40 years of sea temperature observations along the east coast has increase, four times the global average of about 0.6°C per hundred years. A number of fish has decrease quickly because they cannot breed.
In my opinion, climate chang is huge problem because it have an affect on many thing. For example, natural disaster is happen more often. Now many company or shopping center have policy to help our world such as using plastic bag.
