Coal plants burn aluminum?
Alphageds24 t1_j9sk9bq wrote
Context of global warming severity, aluminum particles are probably minor compared to a coal plant pumping CO2 or even methane from the north.
bigsoftee84 t1_j9skm2v wrote
There are more impacts on the environment than just climate change. Burning off tons of metal to be washed down into our water sources is probably something that should be discussed and not waved away because coal plants contribute to another problem.

Earth can't spread its resources to correct every little thing, we need to focus on bigger items. Aluminum oxide in our water is probably minor compared to the acidification of the oceans, also plastic pollution, mercury, etc.
Yes it might contribute but it's minor and so I'd say forget about trying to solve it, fixing it wouldn't change the course in any major way.

This opinion shows little concern for the environment or the future impacts on the environment from new technologies. You want to ignore potential issues because there are already issues. Compounding the problem will never fix it, and adding more trash burning isn't a fix. Prevention of future pollution should be as important as stopping current pollution, otherwise what is the point?

Heavy metals in the water may be really bad for animals, e.g. the European oysters which are nearly extinct in the copper-rich (tiny particles) north Sea. We should care about everything we do to our planet. You don't have to care about everything yourself of course. But don't dismiss it as unimportant just because you don't have the energy to care.

That doesn’t answer the question of what impact if any all the satellites will have.
Unlikely_Plankton_11 t1_j9t6tug wrote
It’s a relevant point to make, because we still have barely started to fix the actual massive problems and people are already bored and looking for distractions in the noise.
Of the two things, coal plants are so hilariously worse and larger in scale that satellites may as well not exist at all for all the difference it makes. When you have people going “yeah yeah coal whatever, let’s look into these satellites though!” it takes up mind space, airtime, political capital, and manpower that could be used on far more impactful things.
And in this case it sure seems like the motive is “ugh corporations,” not genuine concern for the environment.

Exactly my point, and ya totally feels like it's "ugh corporations", and targeting just starlink seems like it's an Elon attack and not at all looking at the satellite junk from many companies and governments.

Coal plants burn what you throw in them, and coal isn't pure. That's how you get things like radioactive coal ash.
The questions to ask next would be along the lines of:
- what metallic contents are found in typical fuel coal?
- how much of that gets into fly ash?
- how different are near-surface metallic emissions and stratospheric metallic emissions?
But I don't have data for those.

Ok, but again, that issue doesn't negate the possible environmental impacts of burning off tons of metal in the atmosphere by a different industry. Does SpaceX get a pass because coal companies are bad? We should be limiting this type of waste and pollution, not trying to wave it away because a different industry is worse.
DreamOfTheEndlessSky t1_j9sn69m wrote
That's not how I read the above comment at all.
I saw it saying something more like "if the satellites create a problem, you could offset that by a small reduction in an existing terrible industry". But, as I pointed out, I don't have sufficient information to connect them as substitutable effects.
bigsoftee84 t1_j9sny23 wrote
Do you remember carbon credits? Incentives to try to encourage carbon reduction? When you offset pollution with another form of pollution, you haven't reduced pollution, just moved the source. We shouldn't ignore one source of pollution for another because we support one industry over the other. We should be reducing all pollution as much as possible, not adding new sources and types of pollution.
DreamOfTheEndlessSky t1_j9ssz87 wrote
That would be a terrible rule. If you can't "add new sources and types of pollution", as you say, you've just eliminated perfectly reasonable ways to significantly reduce the sum: you couldn't use wind power, because it adds a "new source and type of pollution" in the form of broken turbine blades. Your rule, as stated, wouldn't let us consider the drastic improvement it makes in the form of reduced coal/natgas combustion. You would effectively mandate BAU.
veerKg_CSS_Geologist t1_j9t2udy wrote
Wind power is net negative in pollution. It’s not replacing one source with another equal source aka carbon credits.
DreamOfTheEndlessSky t1_j9t3qs1 wrote
Their rule doesn't allow "net negative". They went with "no new positive, no matter how much it helps elsewhere". Any new type of pollution would be prohibited, so the (agreed) significant improvement of switching coal to wind power generation would be disallowed ... showing that it's a bad rule to choose.

You're missing the point. Yes, those materials may be naturally occurring in the earth's crust, but so is carbon. We don't know the effects of this, and it should be studied way before we just allow them to dump tons of new pollution into the atmosphere. The current method is also exceptionally wasteful, I don't understand the waving away of people's concerns. These issues need to be addressed now, not when they become disasters.
When that satellite burns up, those resources are just wasted. We need a real plan to deal with space junk. Burning our waste is part of what put us in this mess. It needs to stop being the default solution. Is the internet so vital that we should continue the practices that put us in the environmental mess we find ourselves in currently?
Fossil fuel consumption is absolutely an issue that needs to be addressed, I am saying we need to be watchful of new waste and wasteful practices. I don't want my grandchildren asking me why we let them poison the sky.
I wish I knew how to properly express my concerns. I live in a state whose fish are poisoned with mercury from the logging industry. There are areas where landfills poisoned the ground. Whole towns smell like rotten eggs because the mills have poisoned the air and water. Everyone let it happen because other issues seemed more pressing. Now the mills are dead or dying, the landfills are leaking, and those responsible are long gone or already rich enough to not care. We are losing trees to invasive species and diseases because folks and companies have more pressing issues.

Why not both?
Otherwise all you’ve done is stand still (say the pollution reduced by shutting down a single coal plant is negated by the pollution from all the satellites).

Do satellites really have that much of an impact where they could potentially cool down the earth?
Alphageds24 t1_j9thcra wrote
MIT did a study Study: Reflecting sunlight to cool the planet will cause other global changes
But it talks about aerosols in the air. So maybe burning them up the aluminum particles would be reflective aerosols?
A satellite reflecting sun back into space is probably very small amount of change, but with 30k maybe it adds up, I don't know.
