Today I'm sorry that another ten rats died from the drugs in the laboratory as the requirement of the experiments.They must have suffered from the pains. Well,it's neccessary and important to complete the experiment and find out the result.
Many people say that we are cruel to treat little animals like that.Most people treat animals as our friends because they are of great help to peaple. So do I . I like animals too.
But many people haven't realized that all the drugs which are used for people have been tested on the animals before they are published. We should make sure the health and safety of human beings. What's more, there are no better motheds at present to solve this problems.Using animals can save the cost of the testing and it's easy for us to raise animals. If we ourselves breed the animals we need in the laboratory we will not break the balance of ecosystem and do harm to human beings.
We all know that the relative law have give regulations on the animals used for testing. So we all raise them carefully ,treat them as our friends and show them respect.
