I think the main problem is that the average Joe/Jane confuses all types of pollution as equally bad. The real, most imminent threat is really CO2. That's what we have to spend the most money/energy on, because it could have absolutely catastrophic consequences in the next few decades.

Plastic in a landfill is just... Stuck there. It's unnatural, sure, but it's not immensely harmful, not nearly on the same scale as CO2, and realistically, in the future, we'll be able to mine it out of there and refine it into something usable if we need it.

Sperm counts have been dropping for a long time (50%-60% over the past 50 years) without stopping, and plasticizers are the suspected culprit. It's incredible how many people need to do IVF now. I would argue that might be the most imminent threat but nobody seems to care.

> Sperm counts have been dropping for a long time

Every couple of years this concern bubbles up. It seems to be established that sperm counts in males are going down. But I’ve yet to see substantial evidence about the possible causes. The effect of plasticisers e.g. were found in animal models usually with rather high doses. An increase of obesity over the last 50 years might also be a likely cause as obesity is linked with hormonal issues. Furthermore, the average age of first time parents has increased significantly. That could also explain why IVF got more popular as sperm counts (and egg „quality“) are age dependent as well.

AFAIK there is no empirical study today proving any link between environmental issues and sperm counts.

I'm certainly no expert, but from what I've seen the scientists are pretty firm in their belief it has nothing to do with obesity or other societal factors. Most of those are fairly easy to control for.

Apparently it's happening in dogs too: https://www.sciencedaily.com/releases/2016/08/160809095138.h...

But not necessarily in farm animals.

We know for a fact that phthalates have an effect on embryo development, and good luck avoiding those.

Just to remind everyone, the decline in sperm count is across species, not just in humans.

So while yes, for people it may be less of an issue, the same cannot be said for wildlife, where it becomes another nail in the extinction coffin.

The need to do IVF is also related to women marrying and choosing to have children later.

Speaking as someone that had to go through IVF, that's a bit like celebrating cancer for reducing the population. Infertility is devastating for you and your relationship when you want to have children.

Re:Plastic-eating enzyme could eliminate billions of tons of... by TameAntelope on Thursday May 19, 2022 @11:27AM (#31435950)
Infertility would be "none", and I didn't say that, I said "fewer".

But I'm sorry you've put such an important emphasis on having kids in your relationship. The fact that you live in a society where that's reasonable is immensely sad, to me.

You should feel whole without children, and the fact that you don't is the real tragedy, IMO.

We leak it all over the place, with no plans to plug the holes. Instead we keep adding new piping all over.

Maybe this is just a joke that sailed over my head, but this is obviously false and doesn't mean anything of the sort. Existential for whom? All you can definitely conclude is that the Earth won't explode if the climate increases by 15 degrees. You can guess that life would survive, but there were no humans back (or large mammals at all) back then. There's no reason to think we would make it.

> The people controlling the media won’t allow it. This is common knowledge.

This is just rank conspiracism. I know of no evidence to suggest that the media are somehow controlling events (?), laws (?), the "narrative" (?), simply to prevent nuclear reactors from being built. How? For what purpose?

And claiming "this is common knowledge"? Maybe that was just another joke, because normally when one says a conspiracy theory is true, one also claims that this is secret information that has to be carefully mined out of various data sources, because if everyone knows something is happening it's usually not a very good conspiracy.

If a country has sufficient nuclear energy then they are immune from international energy politics.

Two, I see that the oligarch class is using global warming alarmism as the driving narrative to move everyone to a carbon credit system, where payouts go to an unaccountable transnational elite.

Ironically, I believe that once the incentive structure is in place, there will be institutional force to keep you buying carbon (offsets) credits… forever.

This is a striking example of what I've observed in many places which has often made me wonder why the intersection between nuclear advocacy and some form of climate change denialism is so large?

People believe if you truly care about reducing CO2 not using nuclear means you will not be able to move off of fossil fuels until we are well past too late.

It's the flaw that makes reducing global warming a talking point vs an actionable item. It's a big elephant in the room.

Until that gets resolved many will think some are spinning your wheels.

Nuclear fuel must first be mined, correct? That's not renewable and could offset the benefits somewhat. That said I imagine it may be better as a base load than dirty coal.

I don't think you realise the VAST amount of energy density in one 1kg of coal vs 1 kg nuclear fuel. "Somewhat" is not nearly the correct comparison !

Re:Plastic-eating enzyme could eliminate billions of tons of... by formerly_proven on Thursday May 19, 2022 @01:45AM (#31431178)
As far as I know that's pretty much exactly the amount of fissile material used annually world-wide.

The caveat is of course that for 1 kg of coal you have to dig up a lot less material than you have to for 1 kg of fissile material - U235 is around 1 % of natural Uranium, and Uranium is around 1 % of the ore.

Nuclear waste is also extremely compact.

The real threat is the nearly 1 trillion tons of toxic waste we're racking up PER YEAR. It's the most lethal stuff this planet has ever encountered.

If the CO2 levels spike, life on the planet (including many or maybe even most humans) will survive. If you look at historic levels, they were hundreds of times higher and the planet was the greenest it has ever been.

If/when that toxic waste leaks out and starts killing, NOTHING will survive.

Radioactive, dangerous chemical, ...

And the thing is that these are actually harming the people who are near the area where they are disposed, so the harm is more direct. CO2 is more like a global problem, so not as worrisome for the local population.

In a way radioactivity is one of the easiest contaminants to deal with: Instant, contact-free testing for levels is trivial with cheap, handheld devices, compared to virtually all other toxic substances which usually require taking samples and analyzing them in a lab. Decay is very well understood and easy to characterize.

Only if you're talking about Putin's Little Green Men, in which case most were last seen heading to their deathbed in Belarus after having exposed themselves to deadly levels radiation after occupying the area and trenching it, to the total dismay of local Ukrainians and Plant workers!

Life does indeed find a way, but not in the way most think.

> In a way radioactivity is one of the easiest contaminants to deal...

What an absurd statement, if that were the case you'd go live and work in Fukushima and take advantage of all the open area and low cost real estate, and all the plentiful food that comes from that region.

Radiation to this day still hasn't been cleaned up in Chernobyl, which happened almost 40 years ago, and an Evacuation Zone is still in place.

And by the way their is an ongoing fire in the area as we speak that is cause for concern [0].
