Man is a part of nature and, by destroying nature, he destroys his future, the future of his descendants. “We are all passengers of one ship called “Earth”, and there is simply nowhere to transfer from it” Antoine de Saint-Exupery Justification of the project

Purpose: to study the influence of anthropogenic factors on human health. Objectives: generalization of knowledge about anthropogenic factors; updating knowledge about pollutants that are very dangerous for all living things; study of the level of pollution of the atmosphere and nature by anthropogenic (artificial) sources
4 slide
Research hypothesis. If a person does not learn to process the products of his activities that are harmful to all living things, then this can lead humanity to disaster and self-destruction.
5 slide
Forms of work: excursions; sociological survey research and calculation work in teams; compiling tables and diagrams using computer technology; student messages and presentations; subbotniks for cleaning and landscaping the village; release of leaflets - appeals to village residents

Stage 2 – sociological survey Do you consider our village clean or polluted?

Stage 3 – research: 1. Identification of the influence of combustion products on atmospheric air. We found out: 1. As a result of burning garbage, a huge amount of carbon dioxide enters the atmosphere, destroying the ozone layer of the atmosphere. 2. When burning polyethylene waste, toxic substances are released (benzopyrenes, carbon monoxide, unsaturated hydrocarbons, dioxins), which suppress the immune system, are carcinogens, lead to early aging, cause genetic changes, suppress human reproductive function, affect the psyche, etc.

Stage 4 – analysis of research results During the study, it was found that the air is polluted by people themselves as a result of their careless activities; The quantitative characteristics of anthropogenic pollutants were clarified and their impact on human health was clarified; We were convinced of the global nature of anthropogenic air pollution and the need for urgent action to clean it up; We learned that snow is an indicator of air pollution; We became convinced that mechanical pollution not only spoils the beauty of our village, but is no less dangerous for human health.

Human progress leads to unwanted pollution of nature and air; The atmosphere knows no boundaries, which means that the air in one place can be strongly influenced by actions taken in another, and these actions must be reasonable. Preserving the purity of nature and air for our and future generations is not only the task of all humanity as a whole, but also of each person individually. Everyone should remember this.

Ecology Ecology is a science that studies the interaction of animals and plants.
What types of pollution are there? People pollute water, air, land.
Water pollution People build factories on the banks of lakes and rivers. Thus, they pollute the water in these reservoirs!
Without water, life on earth is not possible! Each person consumes not 1 or 2 liters of water per day, but much more! there is most water on earth.
Air pollution. Without air, as well as without water, life on earth is not possible! But its people also pollute by building factories, factories and simply by driving a car.
Earth Earth pollution is also very dangerous! Earth. Like everything else, it must be preserved, protected and protected.
What happened cannot be returned! How many beaches have turned into garbage dumps! How many quarries have been dug and abandoned? But there you could relax and enjoy life!
Animals are suffering! Animals suffer from soil, air and water pollution!!!
The situation can still be saved!!! Stop driving! Get up and walk. Don't be lazy! And it will help everyone!
Protect the environment!!! “Take care of nature” - everyone can say! But not everyone can do this.
What is your world like? GREENPEACE is dedicated to protecting nature. But what nature will be like in the future depends on everyone. Including from you!

Ecology is one of the most important disciplines. Here, students learn how to protect and preserve the environment. Unfortunately, it is problematic to learn it qualitatively only from textbooks, and in this case, presentations on ecology will be an excellent way out of the situation. It is much simpler and easier to show something visually than to explain it in words for a long time. Each presentation contains a large number of slides, audio and video, so ecology classes will become truly interesting and educational for students.
Presentations on ecology are made in PowerPoint; here you will find a large assortment of presentations on ecology that can be downloaded absolutely free. To do this, you need to go to the selected presentation and click on the “download” button. Before this, you can see each slide and view their description. You don’t have to download the files first and only then realize that this is not exactly what you need. If you have difficulty finding the topic you need, you can use the search for all presentations, enter a keyword and we will select the most suitable work for you.
Here you will find presentations on ecology for both elementary and high school students. Thanks to the clarity, colorfulness of the slides, correctly structured and divided into blocks of information, the audience will be able to more easily perceive the subject and better concentrate on the topic.
