Mrs. Cugini did become involved in Earth Week. When you think about it, when you walk around your own…

    Earth Day 1970 Part 10: Earth Week 1of3 Philadelphia (CBS News with Walter Cronkite)

    – [Walter] One of the biggest Earth Day observances was in Philadelphia, where an estimated 20-40,000 persons gathered in perfect weather in the city’s largest park. It was an Earth Day success story: a major demonstration in a major city. But, it did not come easily. There were many organizational problems, including a heated controversy over whether to accept financial aid from industries causing pollution. David Culhane followed the Philadelphia story from its start to today’s colorful demonstration. (upbeat hippie music) – [David] Fairmount Park in Philadelphia today. As much like a rock music festival, as a teach-in on the environment. A few older people, a few blacks, and some…

    Clean Air Act – Interstate Pollution

    So how is interstate pollution addressed under the Clean Air Act? Well largely it’s not. The Clean Air Act doesn’t do a great deal to identify situations or prevent situations where pollution or pollutants put in the air in one state affects the compliance with national air quality standards in another state. So you can see how this could become an issue when you build new point sources of pollution near state lines or drift state lines like that and once the pollution goes downwind unto the other state. So the way the EPA dealt with this is, in their approval of state implementation plans, they evaluate the effect of…

    DuPont Makes More Pollution History

    DuPont is set to pay more than $42 million to restore the South River and the wildlife along that river. They’ve been poisoned. One of the former plants in Waynesboro, Virginia was responsible for that. High levels of mercury were detected in the 1970s, making it dangerous enough that you couldn’t eat the fish in that area for many years. Joining me to talk about this is John Rumpler. He’s an attorney with the Environment America. John, my first question has to be how mercury poisoning in a river and the fish swimming in it could still be a problem since these dangerous levels of mercury were discovered in the…

    What Can Beijing Learn From Los Angeles’ Pollution Problem?

    California hosts the top five most air-polluted cities in America. Experts suggest that in the 1960s, LA’s ozone pollution was even worse than in present-day Beijing. So how bad is LA’s pollution now? And how does it compare to other cities worldwide? Well, the World Health Organization and the American Lung Association both measure air pollution primarily by how many fumes and particles exist in the air we breathe. The fumes come from sources like power plants or car exhaust, and are referred to as “ozone” or “smog”. Particles, on the other hand, are solid, and most evident in dust and smoke. Our body is equipped to expel larger particles…

    Trading Pollution: How Pollution Permits Paradoxically Reduce Emissions

    ♪ [music] ♪ – [Narrator] When gasses like sulfur dioxide and nitrogen oxide are emitted into the atmosphere, they react with water, oxygen, and other chemicals to form sulfuric and nitric acid, and when these acids precipitate, we get acid rain. Acid rain can kill trees, plants, and fish, as well as erode automobile paint, buildings, and stone. The Clean Air Act Amendments of 1990 introduced a novel way to combat acid rain — tradable permits. Here’s how they work. Let’s consider two power plants or factories that are polluters. They emit this much polluting gas. The government could control pollution by just commanding that all factories install certain technologies,…

    Protecting Air Quality: Halting Imports of Polluting Engines

    [ship horn blowing] Matt Salazar: Did you know that over 40% of cargo shipments imported into the United States come through the Ports of Los Angeles and Long Beach? All of these goods at this warehouse in Carson, CA are being inspected by Customs and Border Protection, and as you can see, there are a number of illegal goods. EPA is here today looking for imported vehicles and small engines, trying to figure out if they comply with our environmental laws. [MUSIC] We do this important work because cars get smog checked, and small engines and vehicles like this don’t. The sheer volume of small engines imported into the U.S.…

    12. Air Quality Law: Margins of Safety

    Prof: Today, we’re going to embark on a discussion about air quality law. And I’m going to start with really an assertion by the Environmental Protection Agency that I’ve come to think of as a myth of sorts, when they have claimed that the nation’s air quality has improved dramatically in the past twenty-five years. Well, how would you know if that’s true? How would you contest that? What kind of evidence would you want? And what we’ll find today is that your answer to this really depends upon what pollutants you choose to measure, what you know about the toxicity of different pollutants, where you measure the pollutants, do…
