These Stamps issued on " Preserve the Poles and Glaciers " are my most favourite stamps of this year issued on Global warming.The Polar Bears, Seals and Penguins are looking so cute. I wish I could get these awesome Miniature sheets issued by Azerbaijan and Slovenia. Both these Miniature sheets convey the message of creating awarness about global warming. The above one showing an umbrella a symbolic for protection. Factors responsible for global warming like factories, vehicles, overgrazing can be seen on M/s by Slovenia. Just wonderful !
