Australia's lack of commitment on cutting emissions has been noted by other countries. It's too late to start building massive infrastructure, we can't all afford electric cars, yet there is something each of us can do every day.

Animal agriculture is a huge part of the problem. According to the International Journal of Climate Change, animal agriculture is the largest contributor to greenhouse gases in Australia - 50 per cent of our emissions come from the livestock sector.

We can substantially cut emissions three times a day, with our knives and forks. Cut out the meat, dairy and eggs and each of us will appreciably cut Australia's greenhouse emissions, as well as cutting medical bills and saving around 200 animals every year from a miserable life and agonising death.

Unprecedented was an over-used word in 2020, but the call by 17 mayors and councillors from across NSW and Queensland, on the federal government to do more to protect communities from costly and disruptive climate shocks, must qualify as another opportunity to use it ("Councillors' climate call to federal government" 5/3).

How much longer can the Morrison government ignore these calls? Increasingly, they are not from so-called "climate alarmists" but rather they are from business leaders, doctors and scientists.

The federal government's stubborn resistance to step-up on climate change policy and action is out-of-step, not just with an increasing number of Australians, but also the rest of the world.

Mr Porter must be given the full presumption of innocence and he must be given the chance to once and for all clear his name of any wrongdoing or sexual misconduct.

To allow him to do this there needs to be a full, detailed, investigation into his past, any and all allegations of misconduct must be aired and examined by expert investigators.
