You cannot have an ideal world, we do things to the environment, some things are positive, some things are negative,
and we have to understand when the negative effects are much worse than the positive effects,
and I think the sulphur experiment, in that sense,
can be recommended because temperature rises by 2 or 3 degrees are causing major problems all around the globe.
I’m prepared to lose some bit of ozone if we can prevent major increases of temperatures in the future,
say beyond 2 degrees or 3 degrees.
