The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.

Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.

Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.

Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air.

Pollution by carbon dioxide is now the most dangerous kind of air pollution. It is caused by heavy traffic. It is true that if there are fewer people driving, there will be less air pollution.

The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in population at the same time.

In the spring of my career, I found myself questioning the choice of my life’s work. The students did not appear to be motivated; the paperwork was overwhelming (巨大的) and the constant changes of educational direction were discouraging. But I just could not bring myself to do anything else. “Next year,” I would say, “next year I will switch jobs, make more money and have far less stress.” Next year just never came. I am now in my forties. And while I am no longer in the classroom or at the schoolhouse, I remain an educator. It finally dawns on me that there is no other profession that will let me change children’s minds and have an impact on their future. For every student that finally “got it”, for every new teacher that said, “You inspired me to stay,” I get the raise that has never quite made it to my paycheck.

I was on a plane recently and the flight attendant asked my name. When I told him, he said, “I knew that was you! You taught at my elementary school. You made me take my cap off in the building and told me I was handsome.” He then paused and said, “I think I kept my hat on until you saw me, just so I could get that compliment (赞美). Thank you for making me feel special.”

We have now entered an age where nothing is private and secrets are hard to keep. Your “friends” are counted by simply clicking a button. Face-to-face interactions are seen by many as unnecessary and time-consuming. Of course, we can do anything online, including teaching and learning. But I guess I am just old school. I want to look into your eyes when the answer finally dawns on you.
