POLLUTION CE Read this text and answer the following questions:
Thick black smoke curling out of smokestacks, horrible-tasting chemicals in your
drinking water, pesticides in your food - these are examples of pollution. Pollution is any
contamination of the environment which causes harm to the environment or the inhabitants of
the environment. There are many kinds of pollution, and there are many pollutants. Some
obvious kinds of pollution are pollution of the air, soil, and water. Some less obvious, or less
salient, kinds of pollution are radioactive, noise, light pollution, and green-house gasses.
Air pollution can be caused by particles, liquids, or gases that make the air harmful to
breathe. There are two main types of air pollution: primary and secondary. Primary pollutants
enter the air directly, like smoke from factories and car exhaust. Secondary pollutants are
chemicals that mix together to pollute the air, like mixtures of emissions or waste output, from
vehicles and factory smoke that change to form more dangerous pollutants in the air and
sunlight
The effects are quite severe. When it comes to health hazards, the effects of air pollution
include a wide range of diseases such as bronchitis, asthma, headaches, cardiovascular
problems, and even life-threatening conditions such as heart attacks. Other than this, air
pollution also has adverse effects on the environment in which we live. It has the tendency to
cause severe environmental issues such as global warming and acid rain.
Soil pollution can be caused by pesticides, leakage from chemical tanks, oil spills, and
other chemicals which get into the soil by dumping or accidental contamination. Soil pollution
can also cause water pollution when underground water becomes contaminated by coming into
contact with the polluted soil.
The pollution of soil affects the health of children. Damage caused to the brain in the
developmental phase of children is also the result of land pollution. Its effects on the
environment include decrease in soil fertility, disruption of food chain, toxic crop produce...
Water pollution can be caused by waste products, sewage, oil spills, and litter in streams,
rivers, lakes, and oceans. Some scientists believe that water pollution is the largest cause of
death and disease in the world, causing about 14,000 deaths in the world each day.
Noise pollution can be caused by vehicle, aircraft, and industrial noise. It can also be
caused by military or experimental sonar. Noise has health effects on people and animals. In
people, it can cause high blood pressure, heart problems, sleep disturbances, and hearing
problems. In animals, it can cause communication, reproductive, and navigation problems
they have difficulty finding their direction...
