This document discusses air pollution and the Clean Air Act. It notes that the Clean Air Act was established in 1963 to study and clean up air pollution, with the EPA taking the lead role in 1970. The 1990 revisions expanded EPA authority and emphasized more cost-effective regulation. As a result of these laws, the six main air pollutants have decreased over 50% since 1970. The document urges readers to help reduce pollution through energy conservation and efficient transportation. It also explains thermal inversions, how they trap pollutants near the ground, and demonstrates this phenomenon with an experiment.
Title: The Menace of Pollution: A Global Crisis
Introduction:
Pollution, in its various forms, has emerged as one of the most pressing challenges facing the world today. Defined as the introduction of harmful contaminants into the environment, pollution disrupts the natural balance and poses severe threats to ecosystems, biodiversity, and human health. This essay explores the different types of pollution, their causes, consequences, and potential solutions, highlighting the urgent need for collective action to address this global crisis.
Types of Pollution:
Air Pollution:
Air pollution, primarily caused by the release of pollutants from industrial activities, vehicular emissions, and burning of fossil fuels, has dire consequences on air quality. Common pollutants include particulate matter, nitrogen dioxide, sulfur dioxide, and ozone. Prolonged exposure to polluted air contributes to respiratory diseases, cardiovascular problems, and even premature death.
Water Pollution:
Water pollution occurs when contaminants, such as chemicals, heavy metals, and pathogens, enter water bodies. Sources include industrial discharges, agricultural runoff, and improper disposal of waste. Polluted water jeopardizes aquatic ecosystems, harms marine life, and poses serious health risks for those dependent on contaminated water sources.
Soil Pollution:
Soil pollution arises from the introduction of hazardous substances, including pesticides, heavy metals, and industrial waste, into the soil. This degrades soil quality, hinders plant growth, and poses risks to human health through the consumption of contaminated food. Improper waste disposal and the use of chemical fertilizers contribute significantly to soil pollution.
Noise Pollution:
Noise pollution, often a byproduct of urbanization and industrialization, results from excessive noise levels in the environment. Prolonged exposure to noise pollution can lead to stress, hearing impairment, and adverse effects on mental health. Sources include traffic, industrial machinery, and loud recreational activities.
Causes of Pollution:
Industrial Activities:
The rapid industrialization of the past century has significantly contributed to pollution. Industrial processes release pollutants into the air, water, and soil, impacting the environment on a large scale.
Vehicular Emissions:
The ever-increasing number of vehicles on the roads contributes substantially to air pollution. Combustion engines release pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere.
Deforestation:
The clearing of forests for agriculture, logging, and urban development disrupts ecosystems and contributes to air and soil pollution. Trees play a crucial role in absorbing pollutants and maintaining ecological balance.
Improper Waste Management:
Inadequate waste disposal and lack of recycling contribute to water, soil, and air pollution. Landfills and incineration release harmful substances, impacting bot

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. Clean Air Act
• The original Clean Air Act was established in 1963. It
established funding for the study and the cleanup of air
pollution.
• In 1970 Congress created the Environmental Protection
Agency (EPA) and gave it the primary role in carrying out the
law.
• In 1990, Congress revised and expanded the Clean Air Act,
– Provided the EPA even broader authority to implement
and enforce regulations reducing air pollutant emissions.
– Placed an increased emphasis on more cost-effective
approaches to reduce air pollution.

4. Clean Air Act
• By reducing air pollution, the Clean Air Act has
led to significant improvements in human
health and the environment in the U.S.
• Since 1970, the six commonly found air
pollutants have decreased by more than 50
percent.
5. Criteria Air Pollutants
• Ozone
• Particle Pollution
• Carbon Monoxide
• Lead
• Sulfur Dioxides
• Nitrous Dioxides
6. How You Can Help Reduce Air
Pollution?
• Conserve Energy
• Drive Wisely / Ride Wisely
7. Thermal Inversions
Thermal inversion occurs when a layer of warm air
settles over a layer of cooler air that lies near the
ground. The warm air holds down the cool air and
prevents pollutants from rising and scattering.

Your health
Breathing polluted air can make your eyes and nose burn. It can irritate your throat and make breathing difficult.
Pollutants like tiny airborne particles and ground-level ozone can trigger respiratory problems
The environment
Pollutants and the chemicals that form acid rain and ground-level ozone can damage trees, crops, wildlife, lakes and other bodies of water – they can also harm fish and other aquatic life.
The economy
Each day, air pollution causes thousands of illnesses leading to lost days at work and school.
Air pollution also reduces agricultural crop and commercial forest yields by billions of dollars each year.

But there was no comprehensive federal response to address air pollution until Congress passed a much stronger Clean Air Act in 1970. That same year Congress created the EPA and gave it the primary role in carrying out the law. 1970, EPA has been responsible for a variety of Clean Air Act programs to reduce air pollution nationwide.

EPA calls these pollutants "criteria" air pollutants because it regulates them by developing human health based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels.
Ozone - Ground level or "bad" ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight. Breathing ozone can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma. Ground level ozone can also have harmful effects on sensitive vegetation and ecosystems.
Particle Pollution - Particulate matter contains microscopic solids or liquid droplets that are so small that they can be inhaled and cause serious health problems Fine particles are the main cause of reduced visibility (haze) in parts of the United States, including many of our treasured national parks and wilderness areas.
Carbon Monoxide
Breathing air with a high concentration of CO reduces the amount of oxygen that can be transported in the blood stream to critical organs like the heart and brain.
At very high levels, which are possible indoors or in other enclosed environments, CO can cause dizziness, confusion, unconsciousness and death.
Very high levels of CO are not likely to occur outdoors. However, when CO levels are elevated outdoors, they can be of particular concern for people with some types of heart disease.
Lead
Once taken into the body, lead distributes throughout the body in the blood and is accumulated in the bones. Depending on the level of exposure, lead can adversely affect the nervous system, kidney function, immune system, reproductive and developmental systems and the cardiovascular system.
Sulfur Dioxides
Short-term exposures to SO2 can harm the human respiratory system and make breathing difficult. Children, the elderly, and those who suffer from asthma are particularly sensitive to effects of SO2.
Nitrous Dioxides
Breathing air with a high concentration of NO2 can irritate airways in the human respiratory system. Such exposures over short periods can aggravate respiratory diseases, particularly asthma, leading to respiratory symptoms (such as coughing, wheezing or difficulty breathing), hospital admissions and visits to emergency rooms. Longer exposures to elevated concentrations of NO2 may contribute to the development of asthma and potentially increase susceptibility to respiratory infections.

A few examples…
Conserve Energy
■Turn off appliances and lights when you leave the room. ■ Recycle paper, plastic, glass bottles, cardboard, and aluminum cans. (This conserves energy and reduces production emissions.) ■Wash clothes with warm or cold water instead of hot. ■ Choose products that have less packaging and are reusable. ■ Shop with a canvas bag instead of using paper and plastic bags.
Drive Wise
■Plan your trips. Save gasoline and reduce air pollution. ■ Keep tires properly inflated and aligned. ■ Join a carpool or vanpool to get to work.
There are two types of temperature inversions: surface inversions that occur near the Earth's surface, and aloft inversions that occur above the ground. Surface inversions are the most important in the study of air quality.
The most common manner in which surface inversions form is through the cooling of the air near the ground at night. Once the sun goes down, the ground loses heat very quickly, and this cools the air that is in contact with the ground. However, since air is a very poor conductor of heat, the air just above the surface remains warm. Conditions that favor the development of a strong surface inversion are calm winds, clear skies, and long nights. Calm winds prevent warmer air above the surface from mixing down to the ground, and clear skies increase the rate of cooling at the Earth's surface. Long nights allow for the cooling of the ground to continue over a longer period of time, resulting in a greater temperature decrease at the surface. Since the nights in the wintertime are much longer than nights during the summertime, surface inversions are stronger and more common during the winter months.
During the daylight hours, surface inversions normally weaken and disappear as the sun warms the Earth's surface. However, under certain meteorological conditions, such as strong high pressure over the area, these inversions can persist as long as several days. In addition, local topographical features can enhance the formation of inversions, especially in valley locations.

LS2.C: Ecosystem Dynamics, Functioning, and Resilience: Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
Note that thermal inversions create a change in ecosystem – air pollution levels in the local area are raised greatly – the most sensitive populations (elderly, very young, health compromised) are typically affected first and most severely.
The 1948 Donora smog was a historic air inversion that resulted in a wall of smog that killed 20 people and sickened 7,000 more.
The fog started building up in Donora on October 27, 1948. By the following day it was causing coughing and other signs of respiratory distress for many residents of the community in the Monongahela River valley. The smog continued until it rained on October 31, by which time 20 residents of Donora had died and approximately one third to one half of the town's population of 14,000 residents had been sickened. Another 50 residents died of respiratory causes within a month after the incident.
Hydrogen fluoride and sulfur dioxide emissions from U.S. Steel's Donora Zinc Works and its American Steel & Wire plant were frequent occurrences in Donora. What made the 1948 event more severe was a temperature inversion, a situation in which warmer air aloft traps pollution in a layer of colder air near the surface. The pollutants in the air mixed with fog to form a thick, yellowish, acrid smog that hung over Donora for five days. The sulfuric acid, nitrogen dioxide, fluorine, and other poisonous gases that usually dispersed into the atmosphere were caught in the inversion and accumulated until rain ended the weather pattern.
The smog was so intense that driving was nearly abandoned; those who chose to continue driving were risky.
It was not until Sunday morning, the 31st of October, that a meeting occurred between the operators of the plants, and the town officials. It was requested the plants temporarily cease operations. The superintendent of the plants said the plants had already begun shutting down operation at around 6 a.m. that morning. With the rain alleviating the smog, the plants resumed normal operation the following morning.

Cross Cutting Idea: Stability and Change – Small changes (temperature) in one part of a system might cause large changes (air pollutants unable to disperse) in another part.
Discuss how the warm air at a higher elevation than cold air can cause a thermal inversion to occur. This change in the system can cause a “trap” where pollutants are not dispersed, and people, animals, and the environment can be exposed to higher than normal pollutant levels.
Engaging in Argument from Evidence: Use an oral argument supported by empirical evidence (shown in demonstration) to support or refute the explanation for the phenomenon.
