@@David-bj1wh Climate Change is affecting them in other ways, too. It’s forcing manatees to move to areas that they wouldn’t normally inhabit. Manatees evolved to sustain themselves in a regular environment, but the constant fluctuation caused by humans kills manatees because they can only survive in very specific water temperature. Even if climate change didn’t exist, humans are still affecting manatees by killing them on purpose or by accident. Water pollution is especially bad for manatees, as their only food source is at the bottom of the riverbed, which is precisely where a lot of trash ends up. I’m doing a massive research paper on manatee conservation right now. Trust me, the manatees are not fine. We’ve already killed off one entire species of manatee, the Stellar’s sea cow, and we should learn from that mistake.

A possible alternative would be to build solar/wind towers that look like mangrove trees. an when it detects a certain temperature underneath, it releases the energy to warm the water. This gives them a replacement for warm refuge, and if you put carefully made holes in the sides of the tower, an ideal nesting area. Throw in some everbearing or other native berries every other hole, an you basically have a giant warm generating food tree.

Correct me if I am wrong but a *nuclear* plant by itself does not produce pollution? All they do is boiling water with uranium(or whatever it is they are using). I did read the extraction of said uranium and refining does cost a lot of energy(and possibly pollution but then again what doesn't?). Anyway they might have been talking about fossil burning power plants, they're all kinds of nasty.

[@pyrodrayson3216]

@@huldu Thermal pollution. It may not be toxic by most standards, but the hot effluent water from the cooling system that they release into local waterways is considered a form of pollution as it alters the environment it is released into, which is why newer plants are restricted from that practice. I wouldn't *think* they would dump coolant like that from a nuclear plant, because I'd imagine releasing heavy water like that would be... frowned upon... but in hydrocarbon fuelled plants it would have been fairly standard.

3:44 geothermal pumps would be ideal here, if a plant can be found close enough to an already drilled hole. I'll spare you the rabbit hole I went down, but the upshot is discharged oil wells could produce discharged powerplant temperature. the only issues are that the holes are filled with chemicals that we don't want in the environment, so a well sealed heat exchanger would be ideal, and the holes are plugged with cement (so while the drilling costs would be lower, they wouldn't be zero). but adding in a wind or solar powered pump could provide the cows with all the warm water they'd need with a relatively small up front and maintenance costs. so long as a suitable well could be located near by. as an aside natural gas is deeper and hotter, best off serving another purpose.

I remember a show on a local (what used to be a) Japanese tv station that covered a place that used so much geothermal energy that the hot springs weren't as steaming hot anymore.

As far as the danger of geothermal power having a significant impact on the earth's internal temperature as a whole, as of now, not possible. The amount of energy that would have to be removed from the earth and the window of time in which it would have to be done is something unachievable by any technology existing currently. Obviously we can't rule out the development of some massively scaled or incredibly effective technology at some point in the future capable of it, but it would be a herculean task that we are nowhere close to being able to do. I doubt we ever would anyway, geothermal energy would be extremely difficult to develop into a viable option for supplying energy globally. In Iceland, it's brilliant. In India, not so much.

Please include Fahrenheit for us Fhilistines.

[@VariantAEC]

64° to 68°F

[@VariantAEC]

10°C - 12°C is equal to 50°F - 53.6°F This isn't hard it's elementary math. The conversion formula is °C×1.8+32=°F To get Celsius from Fahrenheit (°F-32)÷1.8=°C Simple enough right?

I feel the most profitable salution is a water park for chilling out with a lazy river and food and in the water park in a closed off net work of lazy rivers and man made lakes for manatees and under neath are 1 way mirrors for you to see the manatees in their "natural " habitats praducing tourist dollars to keep the place alive and generating revenue and creating new jobs and will provide a place for scientific study to keep an eye on the health of these animals and behaviors over the years.

[@TheNinjaFam]

If there were other natural habitat the manatee population would have already occupied it. Moving these manatees to other locations would compete with the manatees in those locations until the population reduces. You either have to continue warming the water or accept that the population will be reduced.

[@MuantanamoMobile]

it isn't a binary decision, with proper funding and research, new man-made heated pools can be created with natural sustainable geoengineering methods, not pollution.

[@atomkuehne]

@@MuantanamoMobile that's literally one of the options that was stated, keep warming the waters. There really isn't another option, either warm them or not, if you choose to not some manatees will die.

[@ThevenimX]

Florida resident here. To be honest with you it seems really difficult since a lot of people find it pointless to be wasting tax dollars on something that doesnt benefit themselves so finding a solution that could be similar to what already exists would be ideal but since its been outlawed beyond those who are grandfathered in it seems really tricky to find an appropriate solution. I honestly feel like going nuclear and dispelling the warm water for the manatees seems like the best solution but im not sure if the waters become radioactive and if it does, whats the halflife on the particles until the become stable enough to be considered safe

[@loganflaig6632]

someone correct me if I'm wrong but I'm pretty sure the water wouldn't be heavily irradiated just the Uranium and such used to heat it and the water would be somewhat safe but im not a scientist i just watch videos on youtube all day :/

[@Jake-dh7vh]

In most reactors, even cheaper ones, coolant is run in either a closed-loop or double-closed-loop system, the latter especially if water is to be pumped out and disposed of. It shouldn't ever come in contact with radioactive substances; although, if it does, waste can remain radioactive for decades and shouldn't be considered for natural disposal.

[@baulsaak]

The warm water that would go to cooling towers (that you would like to repurpose to provide a habitat for manatees) is a separate system from anything that would be radioactive, so the manatees would be safe. I think that's actually what they do anyway... isn't that why they are often located near rivers or other waterways?

[@jliller]

Unless something goes very wrong in the plant, the water outflow from a nuclear power plant is not radioactive. If you're thinking of Fukushima it only spilled radioactive water into the ocean because it was wrecked by a tsunami. Nuclear power plants in Florida are built to be hurricane-proof. The nuclear plant at Turkey Point near Homestead took an almost direct hit from Hurricane Andrew in 1992 and suffered negligible damage.

[@jonathanodude6660]

The pollution that was outlawed was heat pollution from excess warm water. Nuclear power plants would also be banned from dumping expelled coolant into the ocean the same way fossil powered plants are.

[@profwaldone]

Seems like localy rolling back the thermal water rules would work realy well. If that waste heat is being pumped into the air anyways, might as well do something usefull with it.

[@yoboi691]

One thing we need to take into consideration is that life will adapt to survive around humans and will eventually thrive, taking into consideration new niches or advantages we create for species to survive.

[@josephmarsh78]

Just your neighborhood starfish stopping by to say hi 👋

[@Comrade_Jason]

This sounds like a Simpsons episode where Lisa tries to shut down the power plant but Mr Burns faux-laments the potential death of the manatees to save his profits.

[@bluesquare23]

We need to absolutely just make warm pools of water that they can swim into during the winter. We caused this, we can fix it.

[@peanutbutter7357]

Wheres the profits for it

[@emceeboogieboots1608]

But we caused the artificial warm water pockets, so by shutting down old power plants we would be fixing it... Kinda sux to be a Manatee. We wouldn't be so quick to try and save an endangered snake that moved into a new habitat that we created 😕

[@UNTBC]

If you believe in global warming, then you should be all for power plants! They will make the ocean warmer and so there will be more manatees, lol.

[@ValeriePallaoro]

And that's exactly what he said .. as well as other things.

[@ValeriePallaoro]

@@peanutbutter7357 The profits are linked to the costs. When the power plants were put up, the full costs were not linked to the building, why are you asking that now? There's always profits in saving the environment. Always.

Hello, I’m hoping you will see my question and help me figure out what to do. I am assembling a full size Periodic Table. That being I am adding elements 58 to 71 and 89 to 103 into rows 6 and 7 respectively. My question is where do elements Scandium and Yttrium belong left or right hand sides. Thanks in advance.

[@lessanderfer7195]

What is 18-20° Celsius in Human Temperature? I understand using the less efficient "centigrade" scale for the smart apes known as humans, because they are unable to understand numbers they can't count on their paws. However, there are 9° Fahrenheit for every 5° Celsius, and it is based on our natural ability to detect Temperature change. Centigrade is like "Temperature for Dummies".

[@own4801]

The United States is literally the only country in the world that uses Fahrenheit, and even there, most professional temperature measurements are done with Celsius.

[@scaper8]

You have to love it. Even when we mange to do something good for a species, we still mange to hurt them in the long run and/or other species in the process.

[@prickayeey8420]

Im actually amazed that a human byproduct is actually temporarily helping out another species rather than killing it

[@sheldonirving9529]

Or just make it illegal to shutdown/decommission a power plant if the bio-diversity of life depends on the temperature of the water. There is other ways to generate heat by using less fuel, such as limit the production of energy from its output, so more heat will return with the wastewater.

[@rattyratstuff7125]

nuclear power plants. one of the cooling stages basically surrounds the reactor coolant lines to cool it quicker. could that work?
