Gregory Andrews is a former high-level Australian diplomat and Threatened Species Commissioner.
He is married, and a father of two teenagers.
He is an Aboriginal Australian.
And he is also currently in the midst of a hunger strike on the lawns of Parliament House in Canberra – all in the name of climate change.
Watch Gregory Andrews speaks about his strike. Post continues below.
For decades, Andrews worked with the government, including being an ambassador to West Africa. It was from this position that Andrews saw first-hand the lack of tangible action being taken by the Australian Government to address climate change. And it began to seriously impact his wellbeing.
"I actually got climate grief, or ecological grief, at the beginning of this year. I found it really devastating to see what science was showing us about the impact and the looming tipping points. To see Tanya Plibersek approve her fourth coal mine since she'd been the Minister for the Environment really hurt," he tells Mamamia.
"Also, as a person of shared Aboriginal and European descent, I feel a real attachment to the bush and our animals, so seeing the impact was heartbreaking too."
