In 1994 I was fortunate enough to see, in the mountains of Rwanda and Uganda, a family of silverback Gorillas, before they were fully acclimatised to human contact.  I would like to avoid anthropomorphism, or unwarranted sentiment, but it was a very touching experience, my impression was that they were strikingly peaceful, beautiful creatures. I found their simplicity in direct contrast to us, their complex neighbours. Human beings had recently perpetrated a horrific genocide amongst themselves in Rwanda, and we, humans, have brought that genocide to the Gorillas too.

What can you do?

The New Scientist has some sound advice

Want to do your bit for the planet, and stop being irritated into the bargain? Then register for the Mailing Preference Service and stop junk mail.  You can also put a 'No junk mail' sticker on your mail box or lettebox.

There is also a Telephone Preference Service that can stop you rushing out of the bath to receive a call from a broken voiced teenager trying to sell you double glazing.
