Hi GD,
Now you will have a big chance to help beaytify and modify BKK environment (starting from your own home ;-) I am sure it will not take lon as people are now more conscious of good environment and younder people are demanding good environment too.
We have been living with snakes for over 20 years (or as we -- humanity -- have been living with snakes for many hundreds millions years), we have no real problems with them. We walk around and come to cross paths with snakes (poisonous and not) many many times, most times snakes would try their hardest to get away from us (makes me wonder if humans are 'that bad' for snakes), only 2-3 times that we had to change our directions. I have relocated many pythons and a few poisonous snakes to more secluded places - away from our chickens and ducks and birds.
Compare to 'cars' I think snakes are much less dangerous than cars, especially cars with some lunatic behind the steering wheels.
My email on Gotoknow is good for contact. I will email my postal address to your email.
