Midgley’s interest in nature led him to study the structure of anthills; his interest in golf led him to experiment with grasses for putting greens. Leaded gas ruined catalytic converters, so it had to go, replaced by sophisticated refining methods that produced high-power gasoline without the need for additives. This application released into the atmosphere far greater quantities of CFCs than refrigeration and air conditioning, which are closed systems that recycle fixed amounts. Nearly as important, it made Tom Midgley a chemist. In my opinion, it's not worth the work and these trees (although attractive when young) are best avoided in landscape situations.
