Reminder to @albomp.bsky.social gov tt the vast majority of Australians care very much abt the impact we're having on nature & the climate & want & absolutely deserve meaningful leadership & action from those elected to represent them

Will you rise to the occasion or treat voters w contempt❓

Biodiversity Council's 2024-25 Biodiversity Concerns Survey of >3,500 Australians found that a majority
😟 are very/extremely concerned about biodiversity issues
☹️ think gov performance at Federal & State/Territory level is terrible/poor/average
💪 want action (96%)
💪 support pro-biodiversity policies
Horizontal stacked bar chart of Concern about biodiversity issues From top to bottom, the issues are: Potential impacts of bird flu on Australian wildlife Impact of renewable energy developments on the environment Native forest logging Taking water from rivers to water crops Land clearing for urban development Land clearing for agriculture Impacts of climate change on native wildlife Decline / extinction of insects and pollinators Impact ofweeds and feral animals on the environment Increasing levels of waste and pollution Loss of natural places Possible extinction of native animals Figure 3. This graph shows how concerned participants were about a range of biodiversity issues. A majority of people were very concerned or extremely concerned (blue groups) about all issues presented. Horizontal stacked bar chart of Government performance for Australia State/Territory Figure 7. This graph shows how participants have rated the federal (top) and their state/territory (bottom) government's performance in protecting nature. The majority of participants rated both as 'terrible', 'poor or 'average' (red and yellow colours). Vertical bar chart of Do Australians want action for nature? x-axis lists the categories (left to right): 'No more', 'A little more', 'Some more', 'A lot more' & 'A great deal more' Figure 5. This graph shows how much more action participants think needs to be taken for nature protection and recovery. Results show that the vast majority (96%) believe at least some action is needed, with only 4% Horizontal stacked bar chart on What pro-biodiversity policies do Australians support? From top to bottom, they are: Strengthen environmental laws to protect nature Establish national standards for the protection of the environment from developments Require native forest logging to be regulated by national environmental law Establish a network of marine sanctuaries that protect at least 30% of different habitat types in Australia's.... Protect native species' habitat from developments such as mines and urban expansion Establish new national parks to protect natural and cultural values Investing in science to understand nature Require businesses to report their impacts on nature Require cat owners to keep their cat contained to their property Remove taxpayer subsidies for industries or projects that damage nature Humanely kill non-native (invasive) species that threaten wildlife and natural places Increase investment for managing Indigenous Protected Areas in line with National Parks Protect and conserve dingo populations as an important part of natural ecosystems Figure 12. This graph shows levels of community support for a range of policies aimed at helping biodiversity. For each policy, a strong majority support the policy (blue bars), while some Australians neither support nor oppose (yellow bars), and a small percentage oppose the policies (red bars).

You don't have to be an Einstein to figure this out.
But...
en.wikipedia.org/wiki/Why_Soc...
Einstein quote (1949): "An oligarchy of private capital cannot be effectively checked even by a democratically organized political society because under existing conditions, private capitalists inevitably control, directly or indirectly, the main sources of information."

An amazing success story: the recovery of humpback whales 50-60 years after we stopped whaling on them.
c0nc0rdance.bsky.social c0nc0rdance @c0nc0rdance.bsky.social · 16d
Another species no longer on the global Endangered list:
Humpback whales (Megaptera novaeangliae).

A few decades after a Star Trek movie where the central conflict was the total extinction of the humpback, their numbers are rising fast enough to put them at "Least Concern" on the IUCN Red List.

NEW data | Less than 50% of Australia's electricity generation came from fossil fuels in October 🇦🇺⚡️

This was the first month ever where renewables have overtaken fossil fuels in Australia's electricity mix.

10 years ago, in October 2015, fossil fuels made up 86%.

NEW: Footage of a US citizen in Chicago being rammed then dragged from her car on her way to work.

Abducted, with no warrant, her family couldn’t find her for hours.

She was later released with NO CHARGE.

A DHS statement said she “violently resisted arrest, injuring two officers”.

📣 New Science Alert!

Bycatch in tropical tuna fisheries is a major threat to manta and devil rays. A new study by Cronin et al. (2025) explores a fisher-designed solution: the mobulid sorting grid, which allows rapid and safe release of these rays.

Fisheries management can work. Check out this recent example where following several decades of fisheries management (including the establishment of massive spatial closures, e.g. 0.8 million km2) affected shark stocks have recovered
