Scientist’s accidental discovery makes coral grow 40x faster
It typically takes coral 25 to 75 years to reach sexual maturity. With a new coral fragmentation method, it takes just 3.
Scientist’s accidental discovery makes coral grow 40x faster
oh something i learned recently that i feel more people should know about is that “plant-based plastic” is not biodegradable! when advertisers say that a product is made with “plant-based plastic,” it just means that the ethanol used in the production of the plastic is made with corn or sugarcane instead of petroleum. advertisers are just betting on consumers not understanding the difference between “biodegradable” and “plant-based,” and using the term as an eco-friendly selling point when plant-based plastics actually create just as much harmful, non-biodegradable waste as traditional plastics.

Most discourse about self-driving cars and nuclear power:
“We need to be more careful about saving millions of lives! A few dozen people might die in the process!”
Honestly, I’m nonzero sympathetic to the viewpoint that technology can make things worse, and we should be cautious about it. You want to argue that social media and clickbait have made our lives worse? That’s a defensible position.
But that caution seems incredibly misplaced when the technology is specifically designed to fix one of the major causes of death in the status quo.
I feel like the main problem here is that people just entirely forget that, like, new tech should be compared to the status quo, not to perfection.
Imagine Toyota came out with a new car, which was half the price of existing cars, and also was twice as safe, and put out half as much pollution. It would be amazing!
Now imagine they didn’t call it a car, they called it a kuruma or something. Everyone would hate it! “Dozens of people are dying in kurumas!” “Kurumas are taking up lanes that could have been used by cars!” The media would report on “The Kuruma Menace”. Some poor people who couldn’t afford cars would buy kurumas, and everyone would complain about the increased traffic/pollution caused by them.
This is how I feel about people’s reactions to basically every transit innovation ever. Scooters, Uber, self-driving cars, Lime, etc. People always hate them even if they’re a strict improvement over cars. Because instead of comparing them to cars, they compare them to what if people stayed home and did nothing.
And, like, maybe that holds water if you’re the kind of person who think everyone should stay home and do nothing. But most of the critics are people who drive cars! I could talk about how not being stuck at home is a human need, that people are willing to pollute and risk their lives for, but I don’t need to, because these people already know that, that’s why they have cars!
Drilling down into specifics: A lot of the criticism of Uber comes because it’s taking people away from public transit as well as from cars. And yes, cars are in fact less safe, more polluting, cause worse traffic, etc, compared to public transit.
But, like, notice basically everyone I know who complains about Uber owns a car.
People who don’t own cars tend to like Uber. It gets them home when buses aren’t running; when they’re in a rush, it gets them in town in half an hour rather than three hours by bus; it lets them go places while being blind; or while in suburbs underserved by transit. It gets them to hospitals when they’re too sick to bike, for 1/50th of the cost of an ambulance. It lets children go places when their parents don’t feel like driving.
But the car owners? They’ll tell you all about how Uber is ruining their city, because it allows poor people and disabled people the convenience of a car every once in a while, and the convenience of a car just happens to come with tradeoffs.
i’d love to hear how your logic ties into nuclear energy
#im with you all the way on the other stuff even though id add in some points #but with nuclear energy im just not so sure #if the tech is as i recall – and this may not be so – the by products of that stuff are extremely deleterious to our environment #in which case perfection should be aimed for
Like the others, nuclear energy is one of those things where it always gets compared to “not using energy”, rather than to coal.
And as long as a single coal plant exists, the question isn’t “is nuclear power better than nothing?” but “is nuclear power better than coal?” – i.e. “should we replace this coal plant with a nuclear plant?”
Because you don’t need to get bogged down in the tradeoffs of “are deaths and environmental effects worth having electric power?” when we as a society have already said ‘yes’ to the same question regarding coal. If you disagree with those tradeoffs, you should be lobbying for dismantling coal, or at least for replacing it with nuclear as we move towards
Estimates for coal deaths range in the millions of deaths per year. Nuclear is responsible for, like, on average, one death per year? Most meltdowns result in zero deaths. Literal meltdowns!
(Nuclear is even safer than solar and wind – if you’re wondering how, people sometimes die falling off roofs while installing solar panels. Nuclear power hysteria kills more people than nuclear power itself does – more people died in the Fukushima evacuation than would have died if they just ignored it!)
Sure, nuclear energy has byproducts which are not great. But the question isn’t “are the byproducts better than nothing” but “are the byproducts as bad as millions of deaths every year?”
Which, even if you didn’t know anything about them, it’s probably less bad than millions of deaths per year, considering there are relatively few things in the world quite that bad, and we’d probably hear about them if they were. [1]
Casual research (skimming the Wikipedia article) confirms this: nuclear waste is being dealt with. There’s room for improvement, but considering there hasn’t been a single death involved, it’s clearly significantly less bad as millions of deaths per year.
It’s not like nuclear waste is magic. We have a pretty good understanding of it: It emits radiation which lessens over long periods of time, and we know how to block radiation, how far away from it is safe, etc etc.
[1] Fun fact: gasoline is one of the few worse things; electric cars are less bad per-mile than gas cars even if the electricity is generated from coal.
I know this has some good points, but please for the love of god do not try and convince people that nuclear energy is good. Nuclear waste is a huge issue actually and the u.s. technically still has no plan in place for it. Also meltdowns can have serious, long ranging and long term effects on people’s health.
Deaths caused from solar or wind are due to improper implementation, not something that the energy in of itself causes. Interactions with coal and muclear energy in of themself cause damage to the environment and to living things.
Do you notice that this is the exact thing I was talking about, though? I could talk about how you’re wrong about how big of a problem nuclear waste and meltdowns are, but I shouldn’t even need to, because they’re nothing compared to the widespread environmental destruction and death caused by coal power.
Deaths caused from solar or wind are due to improper implementation, not something that the energy in of itself causes.
Deaths aren’t less bad when they’re accidental… The deceased’s family isn’t going to feel any better if you tell them it was preventable.
The only way this matters if we’re talking about what we should do in the future, when these deaths can be entirely prevented. At that point, yeah, I agree, we should stop using nuclear power, and switch to, like, Dyson spheres or something. But that’s not relevant to what we should be doing now.
Also, if accidental deaths don’t count, Nuclear has zero deaths.
Not to mention that the half-life for fossil fuels’ impact on the carbon cycle is infinite. It’s just easier to ignore when you can dump your toxic waste into the atmosphere
Also coal power stations still release more radioactive waste than nuclear plants do, just because they burn through so much coal that the trace amounts of radioactive elements adds up. And with nuclear power plants you actually bother with trying to contain it.
How the Belize Barrier Reef Beat the Endangered List
I know we’ve all been bombarded with bad news about the Great Barrier Reef, but I wanted to draw to everyone’s attention the AMAZING steps that Belize has taken to protect the second-largest reef system in the world.
The Belize Barrier Reef is part of the MesoAmerican Reef System, the second-largest in the world behind the Great Barrier Reef in Australia.
In the past several years Belize has taken incredible steps towards protecting its reefs, largely due to amazing efforts by conservation activists and the Belizian public.
“..in 2012 [activists] gained enough signatures on a petition to force a national referendum on oil drilling. But when the government refused to issue the referendum, claiming thousands of the signatures were illegible, activists organized their own “people’s referendum.”
AFP reports that 96 percent of people in the informal vote chose to protect the reef instead of allowing offshore oil drilling. The following year, the Supreme Court of Belize ruled that the oil contracts were illegal because they did not follow the required environmental impact procedures.”
Since then Belize has completely banned offshore drilling in its waters and placed strict regulations on mangrove cutting. They have also implemented taxes to help fund reef support, increased fishing restrictions, and recently announced plans to ban all single-use plastics in the coming year.
It is incredibly inspiring to me to see a country willing to prioritize the preservation of its unique ecosystems even at the cost of lucrative offshore drilling contracts. Go Belize!
Getting a charge from changes in humidity
“A new type of electrical generator uses bacterial spores to harness the untapped power of evaporating water…Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors.”
Think about the way a fallen leaf curls up as it dries out in the fall. Although it’s very slight, the leaf is moving as it curls and that’s because there is a shift in energy going on as water evaporates from the leaf. That’s basically the idea behind this new technology; harnessing the energy stored by biological materials reacting to changes in humidity.
Specifically, researchers are using a bacterium that wrinkles and hardens into a spore in dry conditions but can quickly return to its original shape when it gets wet. Flexible materials coated in these bacteria also flex and straighten in response to changes in humidity and this movement can be used to generate electricity. It may even be possible to genetically engineer bacteria that can react even more strongly to humidity changes.
This technology is definitely still in the early stages of development, but it could potentially have applications as a whole new type of renewable energy.
(Blogger’s Note: Physics is not my strong suit so if I explained this incorrectly please let me know.)
“To fully process what we are losing on Earth, I had to stop responding only as a scientist. My way forward comes instead from my experience of illness. My stem cell transplant wasn’t pointless just because I will, eventually, die of something. The years I’ve gained, however few or many they may be, are precious beyond measure. So too with the Earth. Each generation of humans living in relative abundance, each species saved from extinction for another 50 years, and each wild place left to function and inspire in its wildness, is precious beyond measure.”

‘Carnivore cleansing’ is damaging ecosystems, scientists warn
A plea to restore populations of some of the world’s most dangerous
animals has been made by scientists who claim the loss of large
carnivores is damaging ecosystems.More than three-quarters of the 31 species of large land predators,
such as lions and wolves, are in decline, according to a new study. Of
these, 17 species are now restricted to less than half the territory
they once occupied.Large carnivores have already been exterminated in many developed regions, including western Europe
and eastern United States – and the same pattern of “carnivore
cleansing” is being repeated throughout the world, said scientists.Yet evidence suggests carnivores play a vital role in maintaining the
delicate balance of ecosystems which cannot be replaced by humans
hunting the animals they normally prey on…
‘Carnivore cleansing’ is damaging ecosystems, scientists warn
I see so much shitty news, is there anything good in the world of conservation and env sciences?
Yes! There really, really is.
I know it’s hard not to feel hopeless with the threats of extinction, climate change, and environmental degradation looming over our heads, but there are lots of smart, passionate people out there making a difference.
Here is a small sampling of positive environmental/conservation stories from 2018:
The European Union voted to entirely ban the use of certain single-use plastic products. Increased public pressure on American businesses has led several major chains to voluntarily phase-out certain plastic products used in their stores.
The Ocean Cleanup organization has launched a trial vessel designed to clean up the Great Pacific Garbage Patch. With the information they gain from this vessel they hope to eventually launch many more.
A recent UN report suggests that the ozone hole is healing itself and may be partially repaired by 2030 and entirely by 2060.
While the situation of the world’s coral reefs is still dire, tons of incredibly talented and passionate people are working not just on protecting the world’s reefs, but also on rebuilding previously damaged ones. This just became much easier due to the discovery of a method called “microfragging”, which causes new corals to grow at 40x the usual rate. There will soon be over 100,000 new corals added to the rebuilding of Florida’s reefs.
The kakapo went from being extinct in the wild to now having a steadily growing wild population of 116 birds. Several critically endangered species like keel-scaled boas and California condors were found to be trending upwards in recent population analyses.
In 2018 Hong Kong finally joined the rest of China in banning ivory trade. China also recently banned the “medicinal” use of rhino horn and tiger bone.
Younger generations are shown to be significantly more concerned about issues such as environmental degradation and climate change, so with each passing year a greater percentage of the working and voting population is on the side of environmental protection and stopping climate change.
It’s vitally important that we cultivate an attitude of defiance and hope, rather than one of hopelessness and inaction. One of the most useful skills that people involved in environmental activism or conservation can cultivate is the ability to get back up and keep fighting even after terrible setbacks.
As long as there are people living on this earth, as long as there is a single patch of forest or a single coral reef, this fight will be worth fighting.
Others please feel free to add other positive environmental/conservation stories as I know I only mentioned a small number of them.
Palau, In Western Pacific, Is First Nation To Ban ‘Reef-Toxic’ Sunscreens
Great news from Palau 🇵🇼
Sunscreens with chemicals toxic to reefs are banned nationally, with fines of $1000 for retailers who provide them.
Two chemicals at the top of the no-go list are oxybenzone and
octinoxate. Oxybenzone can be lethal to coral, damages DNA in adults,
and causes developmental deformaties in coral larvae.Worried about sunburn? Plan ahead, stay out of the midday sun cover up,
search for reef-safe sunscreens – small efforts have a huge benefit for
our reefs.
