Parting wisdom:
There is no such thing as a wasted breath because every time a human being exhales airborne plant fertilizer is produced. When we exhale plants inhale, so if you love your plants breathe on them every day. They’ll love it.

A local market gardener burns diesel fuel to produce CO2 to feed into his greenhouses to make the plants grow quicker. He burns it in a motor-generator set and sells the electricity as a waste product!

Hmm. Roses smelling of diesel fumes might be a tad difficult to explain.
