Noise pollution makes us angry more easily. 　　Many countries are making rules (法规) to fight pollution. They stop people from burning coal (煤) in houses and factories in the city, and from putting dirty smoke into the air. 　　Pollution by SO2 is now the most dangerous kind of air pollution.

That means keeping the land, water and air clean. And we must take care of the rise in population at the same time. （ ）1. Our world is becoming much smaller ___.
