What restrictions does the science of life?

The science of life includes all fields of science dealing with the study of living things such as plants, animals and humans.

First say that I am in favor of science because thanks to their discoveries this world can do much better. Thanks to science we have made progress on projects such as: help a disabled person to walk. There are many people who are against it because many animals are used for experiments. But science needs to experience but can not solve the problem. Currently, laboratory mice, a positive aspect in science are used because many of mice.

Secondly there are countries that use science to inadequate such experiments: the monkey experiments used to make parts. A year ago I read an article about science and thought spectacular because recounted draft a new legs to walk. There are many disabled people who have problems and need help but do not have enough money. In this article the company UNICEF helped those people so they could have those objects.

In conclusion I believe science has always been a big plus for our future and I think should be improved without putting impediments because thanks to it many people can live life normally.
