Switching public spending from “grey” projects such as roads and airports, to “ 21 ” schemes such as parks, tree planting and vegetables gardens, would not only 22 the government billions of pounds, improve health, and cut climate emissions(排放物), 23 it would create jobs and make British cities more attractive.

Hospital patients with views of trees rather than of brick walls stay in hospitals for far less time.
