So are we that important?

Humm, but you are saying the Burran is man made, or not? Or are you saying that the landscape of Ireland isn't man made (fields, houses, roads)? That it's not mankind that has cleared much of the worlds forest?

I wouldn't be surprised if plankton did - they certainly alter the reflectivity of the oceans.

Apropos tree planting, I came across a reference some time ago (can't remember where) suggesting that planting kelp forests would be faster and have greater co2 take-up capacity. This article wasn't what I saw, but it's on the same lines

Interesting point, DEW. I am still stunned by learning that the microbial biomass in the rocks beneath our feet, the "deep biosphere", exceeds the biomass in what we regard as "our biozone". I was told this by a microbiologist at the BGS in the '90s and am still getting to grips with the concept.

No county (Lincolnshire) has better churches and worse houses. The poorer sort of people wash their clothes with hog's dung, and burn dried cow's dung for want of better fuel; whence comes the Lincolnshire proverb: "Where the hogs shite soap and the cows shite fire".

And, you know, there is no such thing as society. There are individual men and women and there are families. And no governments can do anything except through people, and people must look to themselves first. It is our duty to look after ourselves and then, also, to look after our neighbours - M Thatcher.

Here's the BBC take on it. Not only is there the issue of transporting living creatures to the Moon, but the question of what happens if you crash them onto it.  Especially if you have decided to do it using one of the toughest little environmental survivors on Earth.

Can't get any more barren a landscape than that.

More bugs than humans. Eh?

Much of the Forest of Dean was felled by Sir John Winter in the 17thC, under licence from Charles I who raised money thereby. Subsequent riots and the need for the Navy to have oak trees for ships meant that it got replanted.

As for Sir John Winter (or Wintour) it was said he was

"wise for himselfe, nimble in inferiour business and delighted more in petty and cunning contrivance than open gallantry..."
