Forests have existed on Earth for 350 million years and provide habitat for many animal species. They also play an important role in regulating climate and air quality by producing oxygen and influencing temperature, moisture levels, and wind speed. However, forests are being destroyed at a rate of 105,000 square km per year, especially in tropical regions, due to logging, infrastructure development, agriculture, and pollution. This is reducing biodiversity and contributing to problems like global warming. To help address this, groups like Greenpeace advocate reducing timber extraction and creating protected forest areas, while individuals can choose recycled products and support tree planting initiatives.

2. Forests
• The forests are on our Earth for 350 million
years.
• Forests have an important place between
ecosystems .
• Forests provide the variety of life forms .
• Human intervention without
sufficient environmental
knowledge can cause damage
of the forest and negative
effects can lead to its demise.

3. Forests are important for people and life.
• They are big producent of oxygen, the
most important factor in climate
regulation.
• Forests help to protect the environment
and air purity, affect the composition of
the atmosphere producing the oxygen.
• They positively influence the
biological, physical and chemical
qualities of the air.

4. The forests influence the weather
• They keep moisture, regulate the
temperature.
• Forests manage the evaporation and rainfall.
• They keep regulation of water regime:
• They direct the outflow – and so they prevent
against floods.
• They also slow down
wind speed.

5. • They are home for animals such as
bear, wolf, deer, rabbit, doe, squirrel, ....
• They are a permanent source of
different berries, mushrooms, herbal
plants.
Forests are home for animals

6. The causes of forests demise
• Uncontrolled logging
• Building infrastructure (cities, highways, dams)
• The change into the agricultural land
• Using the wood as a fuel for households in
developing countries
• Environmental pollution (air, water, acid rain)
• Fires

7. Can you tell us what everything can cause the pollution which
then can damage the forests?
• The biggest pollution of the environment is from
toxic gases from industrial factories and power
stations, exhaust from cars and airplanes, ...
• Wind transports pollutants over long distances.
• Acid rains are often created then.
• Also some diseases of trees
caused with environmental
pollution can appear.

8. Negative consequences:
• The animals lose their home, then the
death of the animal species follow. They are
extinct.
The biodiversity is in danger
• Production of oxygen decreases
• Global warming - the greenhouse effect is
created
• The look of the country can change -
deserts spread.
• Degradation of soils

9. Tropical forests
• Every year, it is destroyed 105,000 km2 of forests,
especially tropical forests. This way it can happen
that in year 2,057 there weren´t no forests.
• As we said forests are destroyed because the
valuable timber is mined.
• Tropical rainforests grow on poor soils, therefore,
after the demise of vegetation the land can be
demaged.
• Deserts can be created.
• Some plants and animals
can extinct.

10. What could we – people do to save
forests?
• Reduce timber mined in forests and rainforests.
• GROUP Greenpeace tries it to do on those
areas where forests still exist- North America,
Russia , South Pacific.
• In Slovakia, Greenpeace concentrates on the
rainforests problems through the project Save
the Amazon Rainforest.

11. Protected area in Slovakia
• In Slovakia, the campaign against deforestation are
organized , the protected areas are created in order to
keep a home for plants and animals.
• Protected areas and National Parks in Slovakia
• Kysuce
• Záhorie
• TANAP in High Tatras
• PIENAP in Pieniny
• NAPANT in Low Tatras
• NP Veľká Fatra
• NP Slovak Paradise – Slovenský raj

12. How could we - students, teachers,
parents help ?
• We should prefer recycled paper.
• We could buy products from another
material, not wood.
• We could help with planting trees and
forests.

13. The Quiz
• Q: How do forests influence the weather?
• Answer:
• They regulate temperature
• They keep moisture.
• They also slow down wind speed.
• Q: Name 3 animals living in the forest !
• Answer:
• A/ bear, wolf, squirrel, fox,...
• B/ lion, tiger, cheetah, leopard..
• Q: How many km2 of tropical forest is destroyed every
year? ( approximately )
• Answer:
• A/ 100 000 km2
• B/ 300 000 km2

14. • Q: How can we help to save forests?
• Answer:
• We should prefer recycled paper.
• We could buy products from another
material, not wood.
• We could help with planting trees and
forests.

15. Protected areas in other countries
• Catalonia - Spain
• Greece
• Sicily - Italy
• Turkey
