The Importance of Forests

This section discusses the importance of forests and their ecological functions.

Forest Coverage

• Many cultures have been supported by products obtained from the forest, such as wood, resins, fruits, and medicines.

• In the past, forests covered between 80% to 90% of the surface area. Today, they cover only between 25% to 35%, depending on location.

• Forests play an important role in regulating water by facilitating infiltration into soil and recharging aquifers. They also influence climate by absorbing carbon dioxide from the atmosphere.

Photosynthesis

• Trees absorb carbon dioxide from the atmosphere through photosynthesis and release oxygen.

Rivers

This section defines rivers and their characteristics.

Definition of a River

• A river is a natural flow of water that continues until it reaches a sea, lake or another river.

• The final part of a river is its invocation.

Natural Resources

• The birthplace of natural resources can be found in areas where rivers originate.

Deserts

This section describes deserts and their characteristics.

Definition of Deserts

• Deserts are terrestrial areas with extreme temperatures where rainfall is scarce.

• Different types of deserts exist around the world with varying levels of precipitation.

Characteristics

• Deserts are extremely hot during the day, with temperatures reaching up to 40-50 degrees Celsius, except for the Sahara which can reach up to 57 degrees Celsius.

• At night, temperatures drop considerably to between 0 and 10 degrees Celsius.

• Severe dust storms or sandstorms called "Tormentas de Polvo" or "Tormentas de Arena" are common in desert regions.

Conclusion

This section emphasizes the importance of natural resources for all living beings on Earth.

Importance of Natural Resources

• All living beings depend on natural resources for survival. Without them, life as we know it would disappear.

Importance of Natural Resources

In this section, the speaker discusses the importance of natural resources such as forests, rivers, and deserts.

Forests

• Forests help regulate water by retaining rainwater and facilitating soil infiltration.

• Trees absorb carbon dioxide from the atmosphere through photosynthesis.

Rivers and Cascades

• Rivers are a natural source of water that flows with continuity.

• The final part of a river is its mouth.

• Rivers in this area are pure and transparent.

Deserts

• Deserts are terrestrial areas with extreme temperatures where rainfall is very scarce.

• Different types of deserts exist, but they are commonly extremely hot during the day and considerably cooler at night.

• The Atacama Desert in Chile is the most arid desert on the planet, receiving rainfall only once every 15 years.

Stormy Mountains

• Stormy mountains are a common phenomenon in certain regions, such as those near deserts.

• They can reduce visibility to zero and deposit upper layers of ground in other places.

Conclusion

• Natural resources are essential for all living beings on Earth to survive.

• It is important to take care of these resources and avoid contaminating our environment.
