    Podcast Summary

    • The Negative Effects of Air Pollution on Cognitive Abilities.High levels of particulate matter in the air can negatively affect cognitive abilities, including attention, memory, and language skills. It's important to check air quality and take steps to reduce exposure.

      Air pollution, specifically, high levels of particulate matter, can have significant negative effects on our cognitive abilities. Studies have shown that exposure to high levels of particulate matter can lead to reduced cognitive performance, particularly in the areas of attention, memory, and language. The impact of air pollution on cognitive ability is equivalent to losing one to two years of education. Despite the well-established health risks associated with air pollution, it is not part of our regular routine to check the air quality before leaving home. It's important to raise awareness about the effects of air pollution on cognitive abilities and to take necessary steps to reduce exposure to polluted air, such as using air filters or avoiding outdoor physical activity during peak pollution times.

    • The Deadly Effects of Air Pollution on Human Health and ProductivityAir pollution poses a significant threat to human life, causing around 7 million deaths globally every year. Exposure to fine particles in polluted air can have cognitive impacts on productivity and carries an economic cost of almost $3 trillion.

      Air pollution is a significant threat to human health and productivity, with an estimated 7 million deaths every year globally due to exposure to fine particles in polluted air. The World Health Organization guidelines set the threshold of particulate matter at 10 micrograms per cubic meter on average, with China at 35 micrograms and the US at 12 micrograms. Air pollution is responsible for more deaths than cigarette smoking, wars, and auto accidents and carries an economic cost of nearly $3 trillion. Exposure to high levels of air pollution has cognitive impacts on productivity and could have larger costs than previously estimated.

    • Air Pollution: A Global Problem With Cross-Border EffectsAir pollution is a global issue, with goods and services consumed outside producing provinces contributing to almost half of China's pollution, and 11% of deaths linked to US and Western European activities. Inter-country collaboration and effective policies are needed to safeguard human health and agriculture.

      Air pollution is not just a local problem but a global one, as almost 50% of China's air pollution is associated with goods and services being consumed outside the producing provinces, with 11% of Chinese air-pollution deaths traced back to goods and services used in the US and Western Europe. While the Clean Air Act passed in 1970 has significantly reduced pollution levels in the US, there are still areas that suffer from pollution such as the Central Valley. Despite this, American crop yields are higher today thanks to fewer pollutants in the air. It is important to recognize that developing countries are still in the process of building their infrastructure and economies, and most environmental regulations came after the US already built out its infrastructure. Therefore, it is critical for all countries to work together and implement policies that reduce the effects of air pollution on human health and agriculture.

    • The Impact of Industrialization on Air Pollution and the Natural EcosystemThe Industrial Revolution caused a rise in air pollution, affecting the evolutionary biology of the peppered moth and resulting in a demographic divide in cities. Pollution's effects on cities are being studied beyond the environment.

      The invention of the steam engine and Industrial Revolution led to a rise in air pollution, particularly in the UK where coal production peaked at almost 300 million tons annually. This pollution had a significant impact on the natural ecosystem, evident in the evolutionary biology of the peppered moth. With industrialization came winds that carried coal smoke, causing a sorting of poorer communities to the east side of cities. Researchers speculate that this demographic divide may have long-lasting effects and are exploring whether pollution has more effects on cities beyond the environment.

    • Coal Smoke and Neighborhood Sorting in Victorian EnglandCoal smoke caused poor households to gradually move to the east side of cities in Victorian England and resulted in a higher concentration of low-skilled workers in that area. Pollution can have long-lasting effects on cognitive capacities.

      Using the geolocations of old smokestacks and the peppered moth as a biomonitor, researchers revealed how coal smoke caused persistent neighborhood sorting in Victorian England. Poor households gradually moved to the east side of cities where coal smoke was blowing to. This resulted in a higher share of low-skilled workers living in the east side in 1881, compared to data from before coal use as the main fuel for industrialization. The relationship between coal smoke and low-skilled workers is not definitive, but studies show that pollution can have intergenerational and long-lasting effects on cognitive capacities.

    • The Negative Impact of Pollution on Children's Education, Health and IncomeChildren living in polluted areas have worse outcomes in education, health and income, and exposure to pollution can negatively impact cognitive abilities and increase the share of low-skilled workers.

      Children living in polluted areas have worse outcomes in education, health, and income, even if they move away later. The effects of neighborhood sorting have become even more extreme, causing areas to become either richer or poorer, and a one-standard deviation increase in pollution can increase the share of low-skilled workers in neighborhoods by up to 20 percent. The snowball effect of initial causes, such as poor people sorting into polluted areas, lesser funding for schools and amenities, and lower cognitive abilities, leads to lower test scores and higher crime. Studies have shown that exposure to particulate matter negatively impacts the cognitive abilities of high school students and adults. A study analyzing baseball umpires showed that umpires made more mistakes on days of high-pollution exposure.

    • The Negative Impact of Air Pollution on Cognitive AbilitiesExposure to air pollution can decrease abilities such as verbal communication, attention, memory, math, problem-solving, and speed. Particulate matter exceeding 25 micrograms per cubic meter can have significant negative effects.

      A study conducted through Lumosity's data of over 100,000 users found that there is a negative impact on cognitive abilities due to day-to-day exposure to air pollution. The study measured various abilities including verbal, attention, flexibility, memory, math, speed, and problem-solving in users across the United States. Researchers Edson Severnini and La Nauze found that particulate matter exceeding 25 micrograms per cubic meter was linked to decreased scores in these abilities. The study did not aim to prove the efficacy of Lumosity, but rather to demonstrate the negative effects of air pollution on cognitive abilities in a diverse array of tasks.

    • The Cognitive Impact of Pollution on Working-age PopulationLiving in a polluted area can adversely affect memory and productivity, especially in people under 50 years old. Sectors relying on memory abilities are most affected. Policymakers need to take this seriously. Check Freakonomics M.D. for more insights on data and intuition in medicine.

      Living in a polluted area can have a significant cognitive impact on the working-age population's productivity and memory abilities. Severnini and La Nauze used wind direction as a uniform level of pollution to measure cognitive function against pollution data across the U.S. Their study found that the largest effects are for people under 50, and productivity impacts will be most significant in sectors that rely heavily on memory abilities. While not all parts of an area will experience the same level of pollution on a given day, their study shows that pollution is a serious issue for the working-age population with policy implications. Check out Freakonomics M.D. for more insights on the hidden side of medicine using data and intuition.

    • Experts Struggle in Lumosity's Fit TestEven experts in psychology and economics can benefit from testing and building cognitive abilities, as highlighted by their struggle with Lumosity's challenging 'Train of Thought' game.

      Despite being experts in psychology and economics, Angela Duckworth and Steven Levitt struggled with Lumosity's 'fit test,' which measures mental flexibility, memory, and attention. The 'Train of Thought' game was particularly challenging, with Levitt calling it 'one of the hardest things' he's ever done. Despite this, Levitt scored an impressive 97%, prompting Duckworth to question his strategy. The experience highlights the importance of testing and building cognitive abilities, even for experts in the field.

    • The Impact of Particulate Matter Pollution on Cognitive Performance, Even Below Recommended LevelsEven if you play brain games to keep your mind sharp, air pollution can harm your cognitive abilities. It's important to be aware of the impact of pollution on your health and take steps to minimize exposure.

      Playing brain games on Lumosity can measure percentile rankings for different cognitive abilities, but particulate matter pollution in the atmosphere can negatively affect cognitive performance even when below recommended levels by the EPA and World Health Organization.

    • The Effects of Pollution on Cognitive Function and Real-Time MonitoringPollution levels can impact brain function through direct effects on neurons or indirect effects through inflammation. Real-time monitoring can help track pollution levels and their impact. Reducing pollution levels is crucial for our health and cognitive abilities.

      Pollution levels can vary greatly even within a single day, and they can have an impact on cognitive function. Higher pollution levels can impair brain function either through direct effects on neurons or indirect effects through inflammation. Real-time monitoring can be a useful tool for tracking pollution levels and their impact on cognitive function. Additionally, pollution can shift someone down in cognitive performance by about six points. More research is needed to fully understand the mechanisms behind this phenomenon, but it highlights the importance of reducing pollution levels for both our health and cognitive abilities.

    • Long-term exposure to coal smoke reduces life expectancyPolicy-makers must prioritize permanent reduction of pollution rather than temporary solutions to improve public health. Studies show significant impacts on life expectancy from exposure to coal smoke, highlighting the need for action.

      Long-term exposure to pollutants, especially coal smoke, significantly reduces life expectancy. Policy-makers should focus on permanent reduction of pollution rather than day-to-day or month-to-month variations. A study on the Huai River winter heating policy in China found that people living on the north side of the river, with free coal and central heating systems, had a life expectancy that was three years less than people living on the south side, with no coal smoke exposure. Policy-makers should learn from such studies and look for permanent reduction of pollutants to improve public health.

    • The Impact of Air Pollution on Education and Earnings in China and the Understated CostsLong-term exposure to air pollution can lead to cognitive damage and reduced education and earnings, with estimates suggesting that the costs are understated by around 50%. Reducing air pollution can have larger benefits than previously thought.

      Long-term exposure to air pollution at concentrations prevalent in Asia and sub-Saharan Africa can cause cognitive damage, with children born to the north of the Huai River in China completing a year less of education and earning 13% less than those born to the south. Estimates also suggest that losses from air pollution have been understated by around 50% and that reducing air pollution could provide 50% larger benefits than previously thought. Countries like China have made significant progress in reducing air pollution, leading to longer life expectancies. However, the US lags behind in recognizing and developing strategies to confront climate change, a global pollutant, not just a local issue of reducing pollution.

    • Acknowledging the Health Implications of Pollution for a Cleaner FuturePollution affects everyone's health, regardless of politics. Educating and creating awareness about its consequences is necessary. Addressing the root problem can lead to better solutions and a healthier future for generations.

      Pollution, both in terms of physiological and cognitive damage, is an issue that affects everyone's daily lives regardless of political affiliation. It's time for everyone to acknowledge the health implications and take action towards a cleaner environment. Educating people about the consequences and making the problem visible is crucial in enacting change. By directly addressing the root problem, we can find more efficient solutions to combat pollution and create a healthier future for generations to come.

    Clearing the Air: The Heart of a Debate (S3 Ep3)

    There is a long history of disproportionately impacted neighborhoods, which are predominately communities of color and low income, experiencing the unequal impact of pollution. This has been the case for many communities in Colorado when it comes to air quality. And while there are competing interests, values, and needs when it comes to deciding what to do, it’s critical to consider who gets represented and heard. Do the policies truly address the issue? And who bears the cost?

    We all have the right to clean air, no matter where we live. But safeguarding our air is about making hard decisions. It’s about changing our thinking and our behaviors. It’s about looking at the issues from multiple angles. People often want there to be a single source or single industry to blame for air pollution, but unfortunately, the air doesn’t work that way.

    Growing Hope

    Growing Hope

    In the last 50 years, Canada's food system has come to be all about efficiency, quantity, and economy - not health, employment, environment, and self-reliance. The response of our communities to this threat, while admirable, is wholly unequal to its magnitude.

    As a special food system issue of the Centre for Community Enterprise's (CCE's) quarterly Making Waves, Canada's community economic development publication invites readers to identify the real issues, the real opportunities, the real difficulties - and to start building a real food system.

    The edition is titled Growing Hope, and will act as a resource to stimulate discussion on the National Practitioners Dialogue - a web board "discussion" designed to gather input from now until March 2007. This discussion will be melded into a draft agri-food policy document to be distributed for comment to web-board participants, Canadian Community Economic Development Network (CCEDNet) members and members of allied community networks across Canada. From this feedback, a polished draft will be debated at the CCEDNet conference in April 2007 in St. John's Newfoundland with other national stakeholders in attendance. The final version will be promoted by CCEDNet and partner organizations in the national dialogue process to take place in Canada in 2007 running up to new Agricultural Policy Framework legislation expected in 2008.

    This project represents the future of sustainable agriculture and food policy in Canada.
