The purpose of the lesson: - to form ideas about the importance of nature in human life; - learn to protect the environment; - to know that every person needs to make a feasible contribution to the cause of saving nature.

Tasks: Who is responsible for what we breathe We will not stand aside Responsibility, not a good wish Summing up

The influence of living conditions on people's health was noticed in ancient times. But only in the 20th century did humanity fully realize that many diseases are directly related to air pollution, poor water supply, and poor-quality products.

People have always had a great impact on the environment, but today human activities are fraught with catastrophic consequences.

A huge amount of pollutants are released into the environment as a result of accidents or failures in technical support systems.

Chemicals destroy the ozone layer, a protective barrier around the Earth's atmosphere that blocks harmful radiation from the sun.

The two main environmental problems are where to get natural resources and where to dispose of industrial waste? - are resolved at the expense of Russia.

2. Imagine this case. On the way somewhere you got hungry and bought yourself a bun. Where will you throw away its packaging? Right where you stood or will you take it to the nearest trash can?

3. Do you take part in greening the city? Do you keep plants in your home?

New concepts Environment is the habitat in which we live. Ecology is the science of the interaction of living beings, including humans, with each other and with the environment. Environmental police is a special service that detects offenses in the field of ecology. Environmental law is special norms that regulate the interaction between man and nature. An environmental offense is a guilty, illegal act that violates environmental legislation and causes harm to the environment and human health.

Airfields, piers and platforms,

Forests without birds and lands without water...

Less and less of the surrounding nature.

More and more - the environment.

IS THERE CURRENTLY A THREAT TO NATURE AND HUMAN LIFE? ?

Over the past 25–30 years, transport and industry have taken more oxygen from the atmosphere than humanity consumed in the entire anthropogen, that is, in 2–3 million years. Sulfur, nitrogen, zinc, potassium, and toxic substances are released into the atmosphere. Only 5 billion tons of carbon dioxide are emitted annually in the world, which can lead to warming, partial melting of polar ice and rising sea levels.
50 Russian cities have levels of environmental pollution that exceed sanitary standards, including our city.

Biologists have already proven that genetic information transmitted to subsequent generations by a living cell can be distorted and disrupted under the influence of so-called “mutants”. These include radiation, active chemicals, toxic chemicals, pesticides, and some metals.
For centuries, everything has been dumped into the seas and oceans without any restrictions, including radioactive waste. Numerous accidents of oil tankers lead to the death of fish, crabs, and seabirds.

According to medical workers, air pollution is responsible for 43–45% of the deterioration in public health.
The quality of drinking water also affects your health. In many regions of Crimea, the direct influence of chemical pollution on the occurrence of diseases of the central nervous system, hepatitis, toxicosis of pregnancy, an increase in stillbirths and congenital anomalies has been established.
Bacterial and viral pollution of rivers creates a constant danger of epidemiological outbreaks of intestinal infections.
In many regions of our country, there is an excess of the permissible level of pesticides in the soil, which leads to children becoming ill with anemia and tuberculosis.
Many plants and animal organisms become accumulators of metals and persistent chemical compounds; their consumption is hazardous to health.

Reckless human activity in relation to nature has brought 1,000 vertebrate species to the brink of extinction. The Red Book includes: 115 species of animals, 25% of birds and 44% of animals that are on the verge of extinction; 118 species of mammals and 127 species of birds have disappeared from the face of the Earth.
35 million people live in the environmental disaster zone in Russia.
Accidents and natural disasters (drought, floods, earthquakes...) cause enormous damage to nature.

First of all, it is necessary to create safe technologies, treatment facilities, we need hospitals with modern equipment... This requires huge funds.
It is necessary to learn how to steward natural resources and communities.
According to scientists, it takes 2000 years for a layer of soil 5 cm thick to form in nature. This greatest wealth was created over centuries, millennia. We must cherish and protect it from destructive consequences.

“Nature cannot cope with logic, with our human logic; it has its own, which we do not understand and do not recognize until it runs over us like a wheel.” I.S. Turgenev
“I picked a flower and it withered. I caught a moth - and it died in my palm. And then I realized that you can only touch nature with your heart.” E.L. Prasolova

Take care of the Earth!

Take care

Lark at the blue zenith,

Butterfly on dodder leaves,

There are sun glares on the path...

Take care of young shoots

At the green festival of nature,

Sky in stars, ocean and land

And a soul that believes in immortality, -

All destinies are connected by threads.

Take care of the Earth! Take care....
