Postal stamps to celebrate nature!
Stamps are awesome. And if you are wondering how big is the gap between teeth on the jagged edge you find the answer in the mind-boggling book Science of Philip Pullman's His Dark Materials
"An atom is only about one hundred-millionth of a centimetre across, so that it would take ten million atoms side by side to stretch across the gap between two of the "teeth" on the jagged edge of a postage stamp."
WOW!
For over 20 years the United Nations Postal Administration (UNPA) has issued stamps to raise awareness of endangered species. This year, the stamps feature a variety of new species added to or updated in the list made by CITES - The Convention on International Trade in Endangered Species of Wild Fauna and Flora. Twelve colourful stamps with endangered species from Masobe gecko to the Natal ginger.
