The document discusses the impact of deforestation on the water cycle, particularly emphasizing the significance of transpiration in maintaining streamflow. It outlines methods to combat deforestation, such as raising awareness, improving land use, and promoting recycling. The conclusion calls for policy makers and individuals to take responsibility and implement strategies to address deforestation.

8. Deforestation
• Transpiration is often
overlooked in
importance.
• About half of rain and
snow that falls at the
Valley is evaporated or
transpired before it
reaches the sea.

9. Input from stem
Output - transpiration
Use - water is used in the plant for
photosynthesis and movement of
important elements.

transpiration
• Modifying
vegetation can
have huge
effects on
streamflow.

population growth and a reduction of forest cover.

20. How can we solve the problem of
deforestation ?

21. HOW CAN WE STOP
DEFORESTATION ?
• Governments have
to make citizens
aware of the issue
including children.
• Reduce wasteful
land use practices.
• Improve already
developed lands.

22. HOW CAN WE STOP
DEFORESTATION ?
• Each person can
plant trees once in
a while to maintain
the ecosystem.
• Groups can be
formed to decrease
deforestation.

23. HOW CAN WE STOP
DEFORESTATION ?
• Recycling : we should recycle
all the thing that are made of
tree ex. Paper, bags, furniture,
etc. Because it lead to the less
cutting of tree and also the
products of trees will be used
wisely.

24. Conclusion
• So it is the time for policy makers
to sit and think seriously about this
issue. New plans and strategies
have to be made to overcome the
problem.
• Rules and regulations regarding
cutting of trees must be followed.

25. Conclusion
Government and society
including us have to feel
their responsibilities and
individuals have to play
their role to reduce the
rate of deforestation.
