My Lords, I am very pleased to support the noble Earl, Lord Caithness, in this amendment. If anything needs a strategy, it is the soil. As was talked about on Monday night, the air, the water and the soil are the three pillars on which we exist, and I would say that the soil is the most important. It is a magical world that we know very little about. People can name the planets, but they cannot name a single thing that lives in the soil. Indeed, it is a whole complex world that lives on a different timescale and on a different planet, as it were, from us because it is all so tiny, but that does not make it any less complicated. As the noble Earl, Lord Caithness, said, 25% of our biodiversity lives in the soil.
As the noble Lord, Lord Deben, pointed out, soil is already degraded, and the five a day we have to eat is now probably four, because we have so weakened this magical substance. We also give it a very bad press. We talk about the dirt beneath our feet; every single laundry advert has someone coming back muddy, as though this is something that we do not like. We treat our soil—this extraordinary world—in the most amazing way, because twice a year, a plough goes through, which, if you can imagine it, is literally like your town, your house and your landscape being bombed to pieces. Despite that, our soil struggles on.
As I pointed out the other day about rivets in planes and when biodiversity starts to turn in the wrong direction, our soils are depleting. Various figures have been given, but most people in this House were nodding when it was said we have maybe 50 harvests left. That may be an exaggeration, but we cannot live on chemicals any more. The soil is also our most valuable means of storing carbon if we treat it right.
Soil is there to help us, to enable us to live on this planet and thrive. It seems to me that this needs a strategy. This is where government should come in. There are lots of people out there campaigning about water and clean air. The soil gets a seriously poor look-in, and if the Government are there to protect the most precious elements of our life, we need a soil strategy.
