News roundup, 8 July 2024

 - French voters in the second round of parliamentary elections have largely rejected the far right; Marine Le Pen's National Rally came third after the left alliance and Macron's centrists. The party's parliamentary leader Jordan Bardella, who hoped to become prime minister, declared that "alliances of dishonor" were responsible for the outcome; perhaps he's learned something from the late Jacques Parizeau. Building a viable coalition may take some time; they don't have a lot of experience with hung parliaments there.

- Joe Biden says he's still not quitting. Unless something happens soon, the Democrats are going to be stuck with him for the fall. This is ungood.

- California has imposed permanent restrictions on water utilities across the state, requiring the utilities to reduce their total consumption by around 40%. How the goal is to be met is up to the individual utilities. There are also efforts by the WWF to encourage other places to grow the crops that California has traditionally supplied. Meanwhile in Florida, where the citrus industry has been decimated by disease, efforts are being made to get farmers to grow pongamia trees, potentially a valuable source of biofuel. Getting farmers to switch away from crops they've been growing for years isn't easy, but it's going to be increasingly necessary in the coming years.

- Boeing has agreed to plead guilty to fraud in connection to the 737 Max disasters in 2018 and 2019, following revelations that the company violated a settlement related to the accidents.

- Solar power is growing so fast that it may be the biggest source of energy on the planet in a decade or so. Growth that experts had predicted could take 20 years happened in only 6. And various industries, notably data centres, are moving to "behind the meter" projects that produce electricity in their own microgrids without having to worry about such matters as feed-in tariffs.

- Canada's new anti-greenwashing law is already spooking energy companies into removing claims from their websites about how environmentally friendly they are, even as they try to claim that the sites they've taken down aren't greenwashing.

- 21 species are being removed from the US Endangered Species list; unfortunately the reason is that they are thought to be extinct.

- Ukraine's largest pediatric facility was severely damaged in a Russian missile strike. At least two people were killed there, in addition to 34 others killed in strikes in other locations.

Some good environmental news for once

The Large Blue has been reintroduced to the UK:

Conservationists are hoping a wildlife success story - the large blue butterfly's return to the UK - will continue this year with a new record for numbers flying at a site where it was reintroduced.

The large blue had vanished from the British countryside by 1979, but a successful reintroduction project over the past 25 years has seen it return to 25 sites, including the National Trust's Collard Hill near Glastonbury, Somerset where it was brought back in 2000.

Last year a record 827 large blue butterflies emerged and flew on the National Trust site - a 22% increase on 2008, which in turn had been a record year.

Unfortunately, this seems to be the exception to the rule; this species and many others are declining on the European mainland.

When Hosts Go Extinct, What Happens To Their Parasites?

Well, in many cases, of course, they go extinct themselves. But there is another possibility:

"There is a distinct possibility that declines in host species could drive parasite species to switch onto alternative hosts, which in turn could escalate the rate of emerging pathogens and parasites both for humans and our domesticated animals and plants," Dunn says. "Put simply, when a host becomes rare, its parasites and mutualists have two choices: jump ship to another host or go extinct. Either situation is a problem."

Dunn noted that the regions where new human diseases, such as bird flu, are emerging coincide with the regions where the most mammal and bird species are endangered. "We have long talked about the negative consequences of the endangerment of the species we love," he says, "but getting left with their parasites is a consequence no one bargained for."
