6. Rewrite the passage below, supplying the appropriate past or passive forms of the verbs given.
Man's efforts to control water
was not always successful. Although wonderful progress
was made in some areas, such as when desert regions
became green and fertile, in other areas great harm
was done. The delicate balance of nature
was upset by lowering water levels or by polluting rivers with industrial wastes. Sometimes the whole climate of an area
was affected by
water changes. In earlier centuries, man
satisfied his needs by living only where water
was abundant. If the land
became damaged, he
moved to a better location.
