The International Comission for the Conservation of Atlantic Tunas (ICCAT) has implanted a new electronic system that strengthened the it. In my opinion I think that the mesures for the protection of animals would be more drastic because a lot of people skips rules and the poor animals are the principal victims.

A breast cancer drug that was approved in 2008 but now the US drug regulators have rescinded
approval of the drug.
I think that if it cause more secundary effects than improve the health of ill person, it wouldn't approved in 2008 and take the time for more investigation. But other rason that could cause the rescinded approval of the drug is that the regulators already arent want so much money although that they won't say that.
