Reacción a "Reactions: mercury concentration in tuna has not been reduced in the last decades"

This is an interesting study that shows that once the sea is polluted, recovery to previous levels is not so easy. The sea has a large capacity for storing pollution, so we can use it as a dumping ground without it being very noticeable a priori. However, precisely because of the large amount of pollutants it can store, when we want to go back, it is not so simple.
