How do you know that is true? How do they come up with these percentages? I don't buy it. The government is becomingly increasingly corrupt over there. They are doing nothing to protect the Great Barrier Reef and even less to combat the fires. They view profits over helping mitigate climate change. The identical thing is happening here with the election of trump and leaving the Paris climate accord. He thinks climate change is "fake news". 10 billion dollar drilling plants are being set-up in Pennsylvania and elsewhere around the country, including Alaska. Once sacred land up there is being excavated for drilling...Same thing with the corrupt government in Brazil with lax restrictions on conversation in the amazon is leading to land being taking apart for cattle ranchers, wood, etc...I'm in the process of going vegan to help the effort a little bit.
I actually have a trip planned to go to Australia and New Zealand in April but may have to cancel the Australia part. Even then NZ is currently a giant smoke cloud. Who knows if it will clear up by then as peak fire season is Jan/Feb.
