AVERAGE RESOURCES(资源)
620 m³ water	If we put flesh water and sea water together，we can each have 620 m³water．But remember，sea water is too salty for us to drink if the factories don’t process(加工)it first．So，620 m³is little．Saving water in daily use is important．
0．5 hectares of forests	There are 3．869 billion hectares(公顷)of forests on Earth．But we are losing them mainly because we cut trees too much．If we calculate(计算)at the size of a football field，we are losing 343，000 football fields every day，or 1，431 per hour，or 24 per minute !
1．5 centimeters long corals(珊瑚)	All the corals that we have now spread(绵延)for about 100，000 km in 109 countries．But each of us can only have such a little piece，because seas are get-ring polluted and corals are dying．
33 stars	According to the latest report，there are 200 billion stars in the Milky Way．Each of us can have 33 of them．Unfortunately，we cannot see most of the 200 billion stars from Earth．We can only see about 6．000 stars．If we don’t use telescopes(望远镜)or we have bad weather，we can only see about 2，000 stars．

Every place offers the possible dangers for getting hurt, even staying at work. We may face dangers like walking into desks or chairs, receiving unexpected cuts from a paper knife and so on. Industrial jobs have similar and more dangers like getting body parts hurt by machines or falling from a height.

No one wants to get hurt. Some accidents are avoidable(可避免的). Most accidents happen because of common things seen every day—an open desk drawer, a chair pulled out too far, water on the floor and so on. We slowly get used to these things we see every day and never think about what they could possibly become in the future.

Think about the following to prevent dangers to yourself and others:

1. If there is something you see and know may become a danger for yourself or others, do something about it. Close a desk drawer, clean up or put a sign over the water, turn off the power before leaving, and so on.

2. Get extra persons’ help and support on a task that is too hard for a single person.

3. Study the situation and think what could possibly happen and change if necessary. Do it before something happens and you won’t have to say some day, “ I should have… How sorry I feel…”

To use an old phrase “ Safety is everyone’s duty.” Looking down on it could lead to being hurt. Keep the rule in mind every day “ Everyone wants to go home in the same condition they came to work in –or better.”
