Ravi's Gadgets

Before the population of the world exploded, and before the invention of oil, the world was a nice place to live. Well people were cutting off all trees for firewood to make charcoal to make metal stuff, but still pollution was not as bad as it is today with all those cars and trucks on the road. When the population was lesser, people could afford land, and all houses were built in the middle of huge farms surrounded by plants and trees. Today, that is a luxury. But still we can try and setup gardens and garden gnomes in front of our homes and get whatever fresh air the grass and the plants produce during their photosynthesis.
