Hi Lucien,
Thank you for the link to the Kew tree planting ceremony....
I'm all for planting trees and shrubs and replenishing the Earth thusly. Too bad The Queen's walnut tree was washed away - walnuts are a vital food for the brain and immune system. And, I'm sure you will agree we need more people with 'brains' in this world!!!
Glad to see she planted a ginko tree though; that will help!!
Cheers,
Larry
