WHEN scientists send spacecraft to other planets, when these are making their journey they must pass through the Ozone layer.
On coming back down to Earth again to return home they must pass back through the Ozone layer.
Each time they pass through the Ozone layer another new hole is revealed and who comes along behind them to make sure the whole is resealed?
When Edinburgh got named Auld Reekie at the start of the industrial revolution there were no holes in the Ozone layer back them as there was no space intrusion.
Scientists are always loath to tell you how much carbon emission each space voyage makes considering the length of time each of these voyages takes.
Including cows for flatulating is an absurd and ridiculous remark considering they and all other animals have been flatulating since before Noah built the Ark.
I can name upwards of 90 creatures in that bracket for hundreds, perhaps thousands of years, surely a wrong statement.
