1.In my opinion,I think it is justified and necessary for medical testing, if we don't testing those new medicines or cosmetics containers,then sale it to people,I can't imagine the consequence when people use the new products without any medical testing.It is not only cause many problems but also who want to pay for those responsibility,I guest no one want and they still can pay for it.So,it is justified and necessary for medical testing,even it is cruel because we sacrifice animal's life,but if we don't do this,more and more people would die by this,and if in this world someone would be die by this,then I wish sufferer amount is the most less.
3.I think many medicines also testing by animals,however,due to those animals,our many medical breakthroughs and people can live for a long time than before.however,cosmetics has the same situation.However,for cosmetics testing,I think it is much unfair than medical testing,because cosmetics end up more expensive and not any people will to use it.It seems use animal's life to earn money,even the starting point is same,no one want sell any new products without testing.Therefore,I still think there are much unfair between medical testing and comes tic testing.Medical breakthroungs will let more and more people get help when they are sick,but the breakthoungs of cosmetics will sell more and more expensive than before and earn more and more money than before.If medicals cost are also more and more expensive,then only rich man can go to hospital and poor man should die because he is poor?
