Both human beings and the animals have the sense of smell,which plays an important part of daily life.We'd never enjoy ourselves without the sense of smell.
The use of the sense of smell is more than this.It can be used in many fields and helps people to solve all kinds of problems.
The animals' sense of smell is usually more sensitive than ours.Taking dogs as an example,we could use their sense of smell to catch the criminals and guide for the blind.
The use of the sense of smell should be developped widely in order to serve the people.
