The meticulous planners of Singapore certainly had trees at the forefront of their mind when they built the city. There are trees everywhere - lining major roads, surrounded by high rise buildings and everywhere in between.
Visitors to Singapore often comment on how green the city is. But amongst the citizens of Singapore, there does not seem to be a lot of tree-hugging greenies. Not long ago a massive beautiful old banyan tree was in the way of new road works. A major intersection of two busy roads was being rebuilt to help traffic flow. There were murmurs to try and save the tree but not many people objected when it was cut down to make way for traffic. Indeed, progress is more important than trees.
In Singapore, not many people actually own gardens as the majority of people live in apartments. No one grows their own tomatoes like in Australia. Most of the food here is imported from neighboring counties like Malaysia, with some of it produced locally. But I think for a small country, Singapore is doing well.
