The world itself is becoming much smaller by using modern traffic and morden communication means （工具）． Life today is much easier than it was hundreds of years ago， but it has brought new problems． One of the biggest problems is pollution． To pollute means to make things dirty． Pollution comes in many ways． We see it， smell it， drink it and even heart it．
Man has been polluting the earth． The more people have， the more pollution becomes． Many years ago， the problem was nor 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．

There are at least two methods．Induction （归纳法） （as described by Darwin ），or deduction （演绎法）（ as described by Einstein）．Both methods can produce amazing result．But only when you know which"direction"to go．
The steps are the same．They include：
Theory （理论）＝Explaining how things work
Experiment＝A way to test what's happening
Observation＝Something you notice
Together，these are called the scientific method．
Should you start from the"bottom"by collecting information and facts to prove and seeing where chat leads you？That's induction．Charles Darwin （1809﹣1882 ） supported this method．He spent years observing the appearance and behavior of animals in different places．From this，he created his theory of natural selection：animal and plants can change because of their environment．
Or should you start from the"top"by creating a theory and then seeing how it stands up to real life？That's deduction．Albert Einstein（1879﹣1955）was king here．He began with brave ideas．These theories often took years to prove by experiment．
A few of Einstein's ideas are still being examined．
In history，scientist have been solving problems using different methods．For example，while studying bacteria（细菌）．Fleming found that something on bread could kill bacteria harmful to human health．This led him to discover a new medicine．Newton suggested that all objects attract each other．His idea was proved later．
So which way better？That depends．Some researchers do experiment，and only later consider where their results may lead them．That's induction．But deduction needs you to suggest a theory that may or may not be supported by the information and facts．The best scientists are always ready to change methods when necessary．
