"Any good gardener knows what a good de-weeding can do for a vegetable garden. As it turns out, it’s much the same for coral reefs.

Following a volunteer “sea-weeding” program launched in Australia, scientists are witnessing compounding coral recovery both in quantity and diversity, and suggest that this simple method has the power to transform degraded reefs overrun by macroalgae.

In a balanced ecosystem, macroalgae is kept in check by the size and health of corals, but as extreme weather events or coral bleaching causes some sections of reef to die, macroalgae has no other neighbor keeping a check on its spread.

Over a period of three years, the joint Earthwatch Institute program led by James Cook University Senior Research Officer Hillary Smith and Professor David Bourne, also at JCU and the Australian Institute of Marine Science, has organized volunteer citizen scientists to help remove macroalgae at two experimental reef sites.

The results of the first three years of work and study have now been published in the Journal of Applied Ecology, and they show a 600% increase in coral recovery rates.

“It’s just like weeding your garden,” Smith said. “Every time we return, the seaweed is growing back less and less, so this method could provide lasting benefit without requiring endless effort.” ...

The importance of the study, Smith details, is that a lot of reef recovery efforts globally are powered by expensive, high-tech, and experimental solutions. The study hoped to show that manual de-weeding was just as effective, and thereby encourage organizations or nations that lack the tech or funding of a country like Australia to pursue sea-weeding as a way of protecting their corals.

“We have yet to see a plateau in coral growth within these plots at Magnetic Island, which is characterized as one of the degraded reefs on the Great Barrier Reef,” Smith said. “We also found an increase in coral diversity, so this method is benefitting a wide range of different coral types.”

Smith said her team are now scoping other locations where the sea-weeding technique could be useful, including the Whitsunday Islands, which are home to a different species of predominant seaweed.

They also want to employ them in French Polynesia, Indonesia, and even Singapore, where experts have identified out-of-control macroalgae spread along coral reefs."

Great Barrier Reef,

Australia 🇦🇺

I might have found a video of a virtual reality experience of the Octonauts!

Whats surprising is that this is made in 2016 and has tons of information regarding the great barrier reef. Another surprising thing is that they are searching for the crown of thorns starfish!

Could this be the great barrier reef special before 2020?

Here is a link to the vr version of the experience ( its a 360 video! No need for a headset)

Help! My Mother-In-Law Buys A New Outfit Every Time She Pours Jet Fuel on Chilean Sea Bass and Throws Their Carcasses, Flaming, Into the Rainforests from the Open Belly of Her Private Plane

Care and Feeding, Slate, 1 May 2023:

Dear Care and Feeding, My husband and I have two children (2 years and 6 months). We recently moved back to my husband’s hometown to pursue a career opportunity for me. My husband has been home with the kids but was just offered a job. We found a daycare, but it can only take the kids three days a week right now (we’re on waitlists for full-time, but it seems like it could be months or more before we find two full-time spots). My mother-in-law has generously offered to watch the kids for the other two days. Overall, she is a lovely, responsible woman, but we have some significant value differences around environmental issues and I’m not sure how to navigate them. Our household focuses heavily on environmental awareness. We drive electric cars, we compost, we limit our air conditioning, we limit our flying, we eat all leftovers, we avoid plastics whenever possible, and we buy exclusively secondhand clothing. My mother-in-law is a big fan of consumption. Her house is full of plastics. She throws away whatever is left on her plate at the end of a meal, she keeps her house so cold in the summer that I need a sweater and she drives a minivan. I’m concerned about the message it sends to the kids if we stick to our values, except when to do so would be inconvenient. How do I bridge our two very different lifestyles going forward? —Environmentalist Mama in Limbo

Dear Environmentalist Mama,

I'm not sure how you can describe a person who air-conditions her home and drives a minivan as "lovely" and "responsible" but I will assume that this planet-hating harpy has gripped you so tightly in her environmentally irresponsible talons that you cannot see the wildfire-ridden forest for the trees (which she is personally cutting down for fun and profit). Do not let yourself be hoodwinked by promises of familial love and generous offers of free child care, as if these things matter more than assiduously composting! This woman is a monster who is single-handedly destroying the only earth your precious babies have to live on. Imagine the tragedies that will unfold if your children experience a loving connection with a person who purchases items made of plastic? They could come to believe that other humans are whole people with their own interior lives and decision-making apparatuses and values instead of ugly nasty baddies who dare to oppose Mommy's One True And Only Way?

You simply cannot bridge two lifestyles as different as the two you describe here. On the one hand, we have your blameless and perfect eco-conscious little household of brave, Dumpster-diving Oliver Twists, and on the other hand, we have an ethically compromised, unscrupulous, indefensibly ignorant shitbird who probably barbecues her factory-farmed meats over asbestos tiles and flies to Australia to distribute the ashes over the Great Barrier Reef. If Planet Earth does not spin out into an apocalyptic ball of climate disaster by the time your children are old enough to be knifing their peers over tire fires for their share of rat rations, it will be because your uniquely virtuous family had the moral fortitude to drive an electric car and limit your flying. After all, electricity comes from magical climate-neutral fairies and the jet fuel industry is waiting with bated breath for the day that you ground your family and send an international behemoth into wholesale free-fall.

If there is one guaranteed way forward through the climate crisis, it is to silo ourselves into individual categories of "good people" who use paper straws (like you! you are so good!) and "amoral reprobates" (such as your mother-in-law, who sucks!) who do not. The very future of humanity depends on demonizing and shaming other people until they behave as we want them to, privileging individual actions over collective resistance to and accountability for the worst global offenders, and rejecting community-building opportunities in favor of being the only best good person ever.

Build no bridge with this woman! She would probably just drive over it with her minivan, and then the blood of billions will be on your hands.

Yesterday I got to live my childhood dream of snorkeling and diving the great barrier reef. Aside from seasickness and ear problems while diving, this was an amazing experience. The colors here are like nothing I've seen before in my life. I'm now desperate to find ID guides on corals and reef fish and to learn more. I'd been hoping to see minke whales (aka guided missiles when they're breaching) but seeing a green turtles more than made up for it. I hope that more of these places are conserved and protected, as they show such a wealth of marine life.

At a time when marine life is disappearing from the world's oceans, researchers are celebrating the discovery of a new species of coral reef fish in the southern waters of the Great Barrier Reef. Named the Lady Elliot Shrimp Goby, the previously unknown fish was found as part of a University of the Sunshine Coast-led project that is mapping the changing biodiversity on and around Lady Elliot Island, a tiny coral cay at the southern end of the Great Barrier Reef.

It has been long thought that Europeans introduced pottery to Australia. However this has now been proven wrong with a new discovery in Queensland. It turns out Australians were making pottery for thousands of years before Europe arrived.
