Oh no don't get me wrong. I was just saying you should be more specific with what's harmful in UV rays. Like I said, it's not harmful to plants that help us reduce carbon dioxide from the air. Since you were speaking in terms of global warming, we don't need to go into it's uses in humans. But that of the plants is what helps cancel out the effect of the halides that form CFCs if you get what I mean. Lol. We could talk about this all day and still be on same point. 😅Thanks for your response
