David Bennett asks how people are going to miss the bottom of the sea 20 miles out in the English Channel (Letters, March 22).

It's not a question of missing it. It isn't a piece of a jigsaw puzzle lost down the back of a sofa but more a question of the impact on marine life it is likely to have.

The trench they are planning to dredge is an important breeding ground for fish that are already being overfished and need to re-establish their numbers.

I suggest Mr Bennett looks down the back of his sofa. If any jigsaw pieces are missing they are most definitely his.
