Write an objective summary for the following article The Industrial Revolution of the mid-1800s introduced incredible technological advances.
However, factories also created new sources of air and water pollution. By the middle of the
1900s, countries around the world were beginning to feel the effects. In the 1960s, an
environmental movement began that sought to stop the pollution. Out of this movement came
events like Earth Day, and legislative victories like the 1970 Clean Air Act and the 1972 Clean
Water Act.
People have been fighting pollution for centuries. In the 1200s, in an effort to reduce air
pollution, England’s King Edward I threatened people in London with harsh penalties if they
didn’t stop burning coal to heat their homes. However, the penalties had little effect.
By the late 1700s and first part of the 1800s, factories began using large amounts of coal to
power machinery. The smog and soot caused by these factories had a serious impact on the
health of people living nearby. In 1952, pollution from factories and home fireplaces killed at least 4,000 people in London. A few years earlier, in 1948, severe industrial air pollution
created a deadly smog that killed 20 people in Donora, Pennsylvania, and made another
7,000 sick.
Acid rain, first discovered in the 1850s, was another problem that came from coal-powered
plants. The rain was caused by factories that released sulfur and nitrogen into the
atmosphere. These chemicals created an acidic rain that hurt plants, fish, soil, forests and
some building materials.
Cars are the biggest culprit
Today, the leading cause of air pollution in the U.S. is motor vehicles. Auto emissions also
increase the amount of greenhouse gases in the atmosphere. By preventing light from moving
to space after reflecting off the Earth's surface, these gases trap heat in the planet's
atmosphere and contribute to global warming.
In 1963, in an effort to reduce air pollution, the U.S. Congress passed the Clean Air Act.
However, in 2007 about 46 percent of all Americans still lived in counties with unhealthy levels
of either ozone or particle pollution, according to the American Lung Association (ALA). The
organization specializes in lung-related diseases, and informs the public about the serious
dangers of pollution. The ALA describes ozone, or smog, as an irritating, invisible gas. This
gas is mainly formed when sunlight reacts with the fumes emitted by cars and trucks, factories
and power plants. Ozone irritates the respiratory tract and can lead to a number of health
problems, including asthma, chest pain and even death.
The ALA defines particle pollution as “the most dangerous, and deadly, of the widespread
outdoor air pollutants.” Particle pollution comes from a complex mix that can include ash, soot,
diesel exhaust, chemicals, metals and aerosols. “Breathing particle pollution year-round can
shorten life by 1 to 3 years," says the ALA. Even when particles appear in low quantity, they
can cause early childbirths, serious respiratory disorders, heart attacks and strokes.
No access to safe water
Just like air, water is also dangerously affected by pollution. For centuries, humans
contaminated sources of drinking water with raw sewage, which led to diseases such as
cholera and typhoid. According to a CNN report, 1 gram of human excrement contains
approximately “10 million viruses, 1 million bacteria, 1,000 parasite cysts and 100 parasite
eggs.” Today, over 1 billion people worldwide lack access to safe water. Every 15 seconds
somewhere on the planet, a child dies from a water-related disease, according to
WaterPartners International.
Water pollution was made worse by the Industrial Revolution. Factories began releasing
pollutants directly into rivers and streams. In 1969, chemical waste released into Ohio’s
Cuyahoga River caused it to burst into flames. The sight of the river on fire became a symbol
of how industrial pollution was destroying America’s natural resources. In 2007, CNN reported that up to 500 million tons of pollutants slip into the global water supply
every year. According to UNESCO, as much as 70 percent of industrial waste is dumped into
the rivers and lakes in the developing world. In China, around 70 percent of lakes and rivers
are now polluted from industrial waste. About 300 million people are forced to rely on polluted
water supplies, Greenpeace says. Water sources are also contaminated by oil slicks on the
road, construction waste, mining and dump sites, as well as livestock wastes, pesticides and
fertilizer from farms. Over half the American population relies on groundwater for drinking
water, according to The Groundwater Foundation.
Too much pollution in waterways
In 1972, Congress passed the Clean Water Act to reduce water pollution. Today the U.S. has
relatively clean, safe drinking water. However, water pollution is still a problem. In 2006, the
Environmental News Service (ENS) reported that more than 62 percent of industrial and
municipal facilities across the country dumped too much pollution into U.S. waterways. The
ENS also noted that over 40 percent of American ponds, rivers and lakes were unsafe for swimming and fishing. Water resources face another threat from man-made environmental disasters. During the
1989 Exxon Valdez oil spill, about 11 million gallons of crude oil were accidentally dumped into
the sea off Alaska. The disaster instantly killed hundreds of thousands of birds, fish and other
wildlife. The area was devastated for years afterward.
