Whatever happened to acid rain? – Joseph Goffman

Spread The Viralist



Discover what causes acid rain, and how scientists were able to largely eliminate this major environmental threat.

In 1963, scientists studying Hubbard Brook Experimental Forest made a shocking discovery. Their most recent rainfall samples were nearly 100 times more acidic than usual; which could destroy the area’s ecosystems in a matter of decades. What was causing this deadly rainfall? And what could be done to stop it? Joseph Goffman details how scientists transformed this major threat into a minor issue.

  1. Scientists: This issue threatens to cause widespread environmental damage that could have severe impacts on human health, welfare, and infrastructure.

    For-profit corporations: But jobs and energy prices (i.e. our profit margins and executive bonuses)!

  2. I'd like to correct a small misconception, the curved tower in the power plant is responsible for cooling the water inside the cycle, thus it produces only steam not pollutants, byproducts of combustion comes from a thin chimney above or near the boilers, and it has to be high enough to disperse the gases away from the immediate area.

  3. For an astute video like this I would like to see "footnotes". 4:35 For example, What "essential organisms" are the government releasing into the air to compensate for being killed off by acid rain?

  4. To the extent that the government grants to certain industry players some number of valuable permits, the cap and trade policy is a subsidy of polluting industry.

    A different policy would sell the permits at auction, then share proceeds from sale to all people.

    The policy will be fair if proceeds are shared equally to all.

    Permits should be for units of impact caused. Permits should not be a perpetual 10 tons per day permission slip (e.g.). (If that policy is in place, it can be effectively converted to a "Pay the people when you impact the env't" policy by taxing the holding of those permits that give access to or benefits from public resources / natural services. Taxing someone for holding an 'X amount of emissions per month' card counts as taxing someone who emits.)

  5. I think if we plant still water lakes, encourage algae growth regulated by snails within the lakes, nearby sources of acid rain, let’s say, a football field lake for every four football fields of city, we could offset acid rain by nurturing this algae alkaline water.

  6. The government also gave all the jobs to China now Acid rain happens in China cause guess what they don’t care about the envirment 👍👍👍

  7. Ozone hole – solved with international cooperation
    Acid rains – solved with international cooperation
    Global Warming – somehow still regarded as a Communists and China conspiracy

  8. From what I've heard, that's actually not possible. There will have to be loads and loads and loads of factories for there to be acid rain

  9. It's in the water
    it chagne the ph of the water look up yukon river was found acid rain since 1998 had this problem nobody really talk about it.

  10. Strange that you never hear about it anymore; I think that success stories like these will cause more people to take action or pressure their government/businesses than the constant gloom-and-doom we're provided with today, even from environmental activists.

    … That's probably exactly why it's not talked about as much.

  11. So we reduced pollution enough for acid rain to clear but climate change is still increasing. It sounds like we either hold the high limiting countries accountable or invest in research that reverses what the pollution started. If these things are not done, then the politicians don't really believe in climate change.

  12. I don't understand how we can come to the conclusion that acid rain is causing these problems when studies, such as from National Acid Precipitation Assessment Program, indicate they don't. I'm sure having those chemicals in the air affects things, probably negatively, but I don't think it's clear what those things are. Plus, after we've reduced acid rain since the early 80s we still have acidic lakes in those few lakes that previously were found to be acidic.

  13. its the "climate change" of the 70's. It's a lie and it didn't have any major impact on science, now what they have is climate change.

  14. This would have been largely irrelevant anyway; Natural Gas is far cheaper than the coal we were using, so it would have replaced it regardless. It was a matter of learning to frack. With no examples given of these supposed atrocities occurring in Russia, India, and China – all three countries I have been too and heard nothing about Acid Rain or its sequelae – I am going to chalk it up to more liberal propagandists trying to claim a win for accomplishing absolutely nothing but higher energy costs.

  15. this is going to come off wrong but notice the bad white countries are the only ones stopping pollution. let hope the acid rain takes down the polluters

  16. Is China suffering any consequences of acid rain? And from what I hear they haven't changed much from what they do have a lot of pollution. I think acid rain might be a little bit overdramatized. Some occupations cannot justify their funding without claiming to provide a solution for a serious problem even that problem has to be manufactured and exaggerated.

  17. You made the "scientists" faces greenish-blue in a misguided attempt of inclusion and all you did was remind me how much I hate this kind of inhuman art.
