Слайд 2ENVIRONMENTAL ISSUES:
1. Water pollution
2. Air pollution
3. Deforestation
4. Global warming
5. The destruction of the
ozone layer
Слайд 31. Water pollution
The quality of water in lakes, rivers, seas and other bodies of
water gradually deteriorates due to the ingress of chemical, biological and physical substances that are not characteristic of a clean body of water.
Слайд 42. AIR POLLUTION
Natural pollution occurs during volcanic eruptions, sandstorms, and forest fires.
Industrial
pollution is emissions from transport, thermal power plants, factories, agriculture, and landfills.
Слайд 53. Deforestation
The importance of forests in our world is very great, and
the destruction of these ecosystems can lead to the most serious consequences.
Слайд 64. GLOBAL WARMING
The main reason for the increase in the average temperature
of the environment lies in the strengthening of human industrial activity. The air and water temperature increased by about 0.74 °C. Despite such a small value, the consequences can be enormous, if you believe the scientific papers.
Слайд 75. THE DESTRUCTION OF THE OZONE LAYER
When the concentration of ozone in the
atmosphere decreases, a person receives an increased dose of ultraviolet light. Scientists have found that this leads to the occurrence of skin cancer and malignant melanoma, as well as to serious eye diseases
Слайд 8CONCLUSION:
As you can see, the risks faced by our world are quite
a lot. However, there is only one reason for them. This is the consumer attitude of a person to the planet, its resources, other living beings that inhabit it, and, moreover, to each other.
