[05:16.97]Trees are useful to man in three very important ways
[05:27.14]they provide him with wood and other products
[05:32.80]they give him shade
[05:35.97]and they help to prevent drought and floods
[05:40.25]Unfortunately,in many parts of the world,
[05:45.68]people have not realized
[05:48.35]that the third of these services is the most important.
[05:53.99]In their eagerness to draw quick profit from the trees
[05:59.24]they have cut them down in large numbers,
[06:03.18]only to find that without them they have lost the best friends they had.
[06:09.43]Two thousand years ago,a rich and powerful 7 country
[06:16.01]cut down its trees to build warships,
[06:19.98]with which to gain itself an empire.
[06:23.77]It gained the empire but without its trees,
[06:29.10]its soil became hard and poor.When the empire fell to pieces,
[06:36.02]the home country found itself faced with floods and starvation.
[06:41.92]Even though a government realizes the importance of a plentiful supply
[06:51.09]of trees,it is difficult for it to persuade the villagers to see this
[06:57.75]The villagers want wood to cook their food with;
[07:03.63]they can earn money by making charcoal or selling wood to the townsmen.
[07:10.61]They are usually too lazy or too careless to plant and look after new trees
[07:18.47]So,unless the government has a good system of control,
[07:24.92]or can educate the people the forests will slowly disappear.
[07:31.09]This does not only mean that the villagers' sons and grandsonshave fewer trees.
[07:40.13]The results are even more serious:
[07:44.41]for where there are trees their roots break the soil up
[07:48.95]allowing the rain tosink in — and also bind the soil,
[07:54.80]thus preventing its being washed away easily.
[07:58.77]But,where there are no trees,the rain falls on hard groundand
[08:05.61]and flows away from the surface,causing floods
[08:10.05]and carrying away with it the rich top-soil,
[08:13.92]in which crops grow so well.When all the top-soil is gone
[08:20.48]nothing remains 8 but a worthless desert.
[00:06.24]Do and Make
[00:08.91]A:Does your mother do most of the housework in your family
[00:14.08]B:Yes.Usually,my mother does the cooking
