RE: UV Sterilizer/UV Bulbs

The sun has been growing plants for a lot longer than we have. Last time I
checked there was more UV getting through the ozone layer every day. The
plants are still growing outside. How do these natural plants compensate for
the intense nutrient depletion that must be provided by the sun? It appears
