3. Look at the picture and discuss the
questions that follow:
1. What do you see in these pictures?
2. What do you like/dislike in them?
3. What would happen if all the
trees were cut down?
4. How are trees helpful to
everyone living on earth?

4. Trees are the most useful things in the world.

5. Children play under them.

6. Travellers rest in their cool shade.

7. Trees give us fruit to eat and firewood to burn.

8. We build houses and make furniture with the
wood of the trees.

9. We need trees for our lives.

10. If there were no trees, there would be no life on earth.

11. Living things (people and animals) breathe in air.

12. They breathe in oxygen from the air and breathe
out carbon dioxide.

13. If all the oxygen in the air was used up leaving only carbon di
oxide, what would happen to all of us? Everyone would die.

14. But trees help us to live.

15. They breathe in the carbon dioxide from the air and let
oxygen out into the air.

16. With the help of the sunlight, they break up carbon
dioxide into carbon and oxygen.

17. They use the carbon to make starch and let the oxygen
out into the air.

18. Trees make all the starch in the world.

19. Starch is the most important part of our food.

20. Without trees we will not have any starch to eat.

21. Trees help us to get rain.

22. The leaves of trees breathe out a lot of water
vapour into the air.

23. This makes the air cool.

24. The cool air helps rainfall.

25. Rain gives us water.

26. No one can live without water.

27. And we need trees to get water.

28. Trees have many more uses.

29. The rubber tree grows in many parts of the world.

30. From the sap of this tree we get rubber.

31. Rubber is a very useful thing.

32. Some trees like eucalyptus give us medicines.

33. In South America there is a tree called the cow tree.

34. People drink the sap of this tree instead of
milk! It is less expensive than milk.

35. How long can a big tree live? Nobody knows.

36. Some trees have already lived for more than four
thousand years.

37. They can live for five to six thousand years more. Some
of them will live as long as ten thousand years.

38. There is a tree called General Sherman in California
in America.

39. It is a huge evergreen tree. It is said to be
several thousand years old.

40. How do we know the age of a tree? Do trees have
birthdays? Yes, they do.

tree age

41. They even get gifts on their birthdays. They
get rings!

42. Every year a tree grows a little bigger.

43. As it grows, the trunk gets another layer of wood;
it gets another ring.

44. You cannot see the rings because they are
inside the tree.

45. But if you look at the trunk of a cut down tree carefully,
you will find the rings. One ring means one year.

46. Some trees can live only for five to ten years.

47. But some can live for hundreds or even thousands
of years, like General Sherman.

48. Man cuts down hundreds of trees every year to
build houses, to make furniture, to cook food, and
to make paper.

49. If this continues, one day there will be no more trees in
the world. What will happen then? We will all die!

50. So what shall we do? We should avoid cutting
trees as far as possible.

51. Meanwhile, we must plant a lot of trees.

52. Every one of us should plant at least one tree every year.
