Lesson 9. Theme: Speaking: Global Problems. Discussion of the topic and answering questions
Pollution
Pollution is one of the worst side effects of the human society development on the planet because instead of protecting the natural habitat, we are destroying the air, the water and the soil, which turns the natural environment into a nightmare for both people, animals and birds.

Air Pollution

is produced when harmful chemicals and particulates are released into the atmosphere, producing different types of allergies and diseases that can lead to the death of people, birds and animals.
Air pollution is produced when we burn fossil fuels to generate electricity and heat, and also when we use a car based on fossil fuels such as gasoline or diesel.
Air pollution is also produced by the industry and the manufacturing processes of different goods, but also by agricultural processes and household activities. Air pollution can be also generated by natural processes such as active volcanoes, tropical storms, dust that is lifted from the ground and carried by the wind, methane produced by humans and animals and smoke produced by wild fires.

Soil and Land Pollution

The number of landfills increases every year in the U.S. because more trash is produced by the growing population and due to the fact that only a small number of products are recycled, the landfills are heavily polluting the soil and the ground water with dangerous chemicals.
Land degradation or land pollution is produced when human activities such as mining, littering, deforestation, construction, industrial and agricultural activities are taking place without taking into account that we are destroying the natural habitats and a large number of species.

Water Pollution

Freshwater and seawater is polluted when we spill dangerous chemical substances into streams, rivers, seas and oceans.
Environmental accidents are produced by the sinking oil tankers, by spilling dangerous chemicals into the water and by depositing barrels filled with nuclear waste on the bottom of the sea.
