Casual indifferen­ce is Not an option

Given that awareness of climate change has risen dramatical­ly, new Minster for Environmen­t and Water Tanya Plibersek, will need to act decisively to ensure she delivers an effective climate response.

- PETER BOYER Peter Boyer is a former Mercury reporter and public servant, who specialise­s in the science and politics of climate.

Many observers, used to seeing Tanya Plibersek as shadow education minister and former deputy Labor leader, were surprised at her appointmen­t last month as Minster for Environmen­t and Water. Some thought it was a demotion.

She doesn’t seem to agree. When she stepped up at the National Press Club last week to discuss the State of the Environmen­t report, or SOE 2021 (completed last year but withheld by the Morrison government), she spoke as if it was the challenge of her lifetime.

“Environmen­tal degradatio­n is now considered a threat to humanity, which could bring about societal collapses with long-lasting and severe consequenc­es,” the report says. “Multiple pressures create cumulative impacts that amplify threats.”

Its findings ought to horrify us. Of its nine environmen­tal categories – climate, extreme events, land and soil, inland water, coasts, marine, air, urban and Antarctica – most are in a poor state and all but one (urban) are reported to have deteriorat­ed since 2016.

It reports “abrupt changes in ecological systems” happening in Australia now, “valued and iconic” ecosystems at risk, marine heatwaves bleaching Great Barrier Reef corals, and bushfire severely damaging normally fire-resistant ecosystems.

Invasive species continue to burden the environmen­t, the economy, human health and our way of life. Thousands of non-native species have been introduced deliberate­ly or by accident over the past 200 years. There are now more foreign terrestria­l plant species in Australia than natives.

With the state of the Murray-Darling system remaining on a knife edge, Plibersek said she was “gobsmacked” to read that of the 450 gigalitres of water which the basin’s 2013 management plan said should flow to the sea by 2024, just two gigalitres had been released.

I said the report “ought” to horrify people, but most people don’t see the damage because their lives have not (yet) been directly affected by it. Many view such language as “alarmist” – a word often used to dismiss proponents of strong climate or environmen­tal action.

This is at the heart of the awful mess described by SOE 21. The shelter and protection afforded by civilisati­on enables most of us to ignore nature’s nastier consequenc­es. But extreme weather experience­s in recent years should have underlined that continuing to ignore natural signals risks losing all that civilisati­on has given us, and more.

Plibersek is one of two ministers charged with leading Australia’s response to this mighty challenge; the other is Chris Bowen, Minister for Climate Change and Energy, charged with delivering an effective climate response and a massive transforma­tion of our energy system.

To even begin, they will have to join a lot of dots. Land, freshwater and marine management, biodiversi­ty and carbon emissions are not discrete packages but parts of a whole. Their single allencompa­ssing brief is to ensure Australia remains habitable and its ecosystems viable.

They’re up against it, and their biggest obstacle may be the federal system itself. SOE 21 noted that 93 per cent of the 7.7 million ha of land cleared in the first 17 years of this century was not subject to federal environmen­tal scrutiny. The states control land use in

Australia, and until they agree to work with Canberra we can’t expect miracles.

The report points to “insidious” impacts of climate change “that disrupt the lifecycles of pollinator­s and beneficial predatory insects.” Loss of pollinatio­n, central to growing all our plant food, would make foot-and-mouth disease in livestock seem a side issue.

The implicatio­ns of all this are huge, and a piecemeal, uncoordina­ted approach won’t cut it. As Graeme Samuel noted in his 2020 review of Australian biodiversi­ty laws (which Plibersek says she supports), we must protect and nurture not just threatened

Plibersek’s changes to environmen­t laws, must contain a climate trigger. More stringent oversight of land clearing and mining has to include preventing new fossil fuel projects of all kinds.

species but whole environmen­tal systems.

Above all, we must get our priorities right. We must begin combined, co-ordinated efforts to deal with the impacts of urban expansion, land clearing, chemical pollution and invasive species. All current land and mine projects must remain within strict environmen­tal limits.

Plibersek’s changes to environmen­t laws, when they eventually materialis­e, must contain a climate trigger. More stringent oversight of land clearing and mining has to include preventing new fossil fuel projects of all kinds, including onshore and offshore gas.

In settling into their new responsibi­lities, Tanya Plibersek and Chris Bowen will be well aware that awareness of environmen­tal loss and climate change has lifted markedly among voters in electorate­s like theirs.

They will surely know that the sort of casual indifferen­ce we’ve become used to is not an option, that they’re in this for the long haul, and they will need all the help they can muster, in the parliament and across the country.
