Since a little while ago, we have been talking about reducing emissions at the source, which is clearly simpler, to my mind, than having to clean it up once it has got into the environment.
On the weekend, I spilled a glass of wine on a carpet. Until I had to clean up the mess, I had never realized how much a wineglass could hold. I think it is probably the same thing once a product has spilled into the environment. When the time comes to decontaminate, it is definitely more complicated.
I do not understand how it is that still today people wonder whether certain products should be completely withdrawn rather than running the risk of spilling them and watching them end up in the environment.
