LAST CHANCE

Good evening, ladies and gentlemen. Thank you all for coming here and listening to my story. Let me begin by telling you how I came to be here: I came in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth.

I have returned to this year to tell you something important: This year is your last chance to change your lifestyle to save the earth!

I will explain. Beginning in the middle of the 20^th century, a few people were worried about polluting the earth's water and air. They talked about the dangers of pollution, but most people did not listen and did not change their way of life. Instead, they continued to dump dangerous chemicals and other waste into lakes and oceans, to drive more and more cars and trucks and to cut down trees.

By the year 2200, the earth's water was completely polluted. People could no longer drink water, and they had to use other types of liquids. This forced a change, but it was not enough. Scientists warned about over­population and said that in the future there might be too many people on the earth. But not enough was done.

So, by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in the lakes and oceans died because of pollution. Terrible wars broke out between the wealthy and the poor. People started to think about finding another place to live. Scientists were working very hard to find another planet in space where humans could live.

By the year 2400, the air was too polluted for humans to breathe. So we had to leave earth.But only the very wealthy were able to leave. Where did we go? Nowhere. And everywhere. You see, scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.

So, it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.
