The situation of the Mar Menor is critical as we know, and it is not a matter of "making firewood from the fallen tree", or opportunism of any kind, seeking guilty instead of solutions.
The 21 recently approved measures are necessary, but in my opinion they will not be enough to avoid huge trawls in case of very heavy rains by cold drop or DANA, which unfortunately seems to be much more frequent than before.
If we really want to protect or even more "shield" the Laguna Salada, against daily leaching and occasional phenomena of large avenues, we must be able not only to try to retain a part of the volume of water as intended with the 21 measures, if not to divert what we cannot collect upstream, and to leave the Mediterranean.
That last insurmountable barrier of protection for the Mar Menor and the coastal towns, would be a great channel for the collection of trawls and leachate (black line on the map), and that could also be converted into a huge artificial wetland, which would filter the contributions daily nitrates, phosphates, brine and other substances that will continue to reach the lagoon.
Below I put a simple outline of what could be the profile of that channel with wetlands.
