Supply disruptions affect food prices, most affecting people on low incomes and those already food insecure. Fewer than 5% of Australian adults eat the recommended number of vegetable servings daily. If everyone did, we would not have enough. Led by Dr Rachel Carey, the Foodprint Melbourne project seeks to increase equitable access to fresh, healthy foods and promote sustainable production for current and future generations of Australians.
The home of the Eastern Barred Bandicoot once stretched from Melbourne to the South Australian border. In the 1970’s, the population dropped to around 1000 and then, within a decade, there were only 150 left. The last refuge of the EBBs was in Hamilton – one of the last places in Victoria they could be found in the wild. In 1988, the EBB Recovery Team was formed to respond to the continued population decline, and they had to act quickly.
Taxonomy provides a way to communicate information about species and their context in nature. Australia is estimated to be home to 600,000 species of flora and fauna, yet 70% remain unnamed. At the current rate, it will take 400 years to identify them all. New technologies such as genetic sequencing, artificial intelligence and supercomputing can help speed up the process before extinctions make it impossible.
As a custodian species of the planet’s ecosystems, we have become disconnected from our responsibilities, attending to the patterns that build the complex web of life. Our activities and waste products are disrupting ecosystems, impacting the reproductive success of other animals. Pharmaceutical waste can persist even in the most remote places on the planet, including Antarctica. But it’s not all bad news, particularly if we pay attention to where we’ve come from, and where we’re going.
‘Plate tectonics’ describes fragments of the Earth’s outer shell that move against, over, and under one another at their boundaries, slowly changing the shape and location of our continents and oceans. The theory revolutionised the Earth sciences field by providing an understanding of how mountains are built, volcanoes erupt, and earthquakes are triggered. But while the theory is now a given, this hard-won scientific consensus represents an historic moment in living memory.
