Read the following passage carefully:

Read the following passage carefully

1. Trees are very useful. They supply us with daily conveniences. They help to support man's life by supplying the atmosphere with oxygen which is essential for life. The oxygen in the air is constantly being used up and turned into carbon dioxide when animals breathe and things burn. The green leaves of trees (in fact of all green plants) absorb this carbon dioxide and with the help of sunlight, break it down into carbon and oxygen. The carbon is used to make starch and the oxygen is released into the atmosphere.

2. You must have noticed how, on a hot day, it is often cooler under a tree than inside a building. This is because the leaves of trees breathe out water vapours and they help to cool the air more or less as a mudpot cools the water in it. In this way, forests help to cool the atmosphere and rain clouds passing through it cause rain. Where new forests have been planted, rainfall is known to have increased.

3. Trees help to protect the surface soil of the earth and prevent floods. Their roots hold the soil together, and thus, the soil is protected from being washed-off. Moreover, forest soil has a way of quickly absorbing water which helps to prevent sudden floods.

4. There are many kinds of trees that are very useful to man. There are rubber trees growing in Kerala, Assam and Malaya from whose sap we get rubber which we use for numerous purposes. There is the coconut tree, every part of which is useful. In South America, there is an interesting tree called the 'cow-tree' whose sap is used in place of milk.

5. Trees are important not only for man but also for birds and animals. Their branches give shelter to millions of birds, and forests support the lives of many kinds of wild animals.

6. We value trees not only for their usefulness but also for their beauty. They have a way of refreshing the eyes and bringing peace to the mind. Perhaps that is why our ancient Rishis were attracted to the forests and they chose to live with their pupils in forest homes in the company of nature. When Rabindranath Tagore started a school, he too chose a place full of trees for his school and called it 'Shantiniketan' or the Home of Peace.
