How far can scientific experiments on living creatures be justified?

Man has been able to modify simple organisms so that they will produce proteins for human health purposes. Patients suffering from terminally ill diseases have used these proteins to make their lives easier and less painful. Man has been able to alter the genes of certain crops in order to make them more resistant to certain pests and diseases, resulting in a greater yield. Man can also be able to ‘hand pick’ desirable characteristics such as manipulating genes in trees to absorb more carbon dioxide to reduce the threat of global warming.  In this positive sense, one can see that ...
