1) We need UV radiation to derive Vitamin D in our body.
Only a narrow sub-band called UV-a.
2) UV radiation has many other health and ecological benefits.
That it does. UV light is what creates the ozone layer. UV-b light, when absorbed by oxygen converts that oxygen to ozone. UV-c light, when absorbed by ozone, converts that ozone to oxygen.
No UV-c light reaches the surface of Earth. It's only surface source is arc welding and certain pieces of specialized equipment.
Only a little UV-b light reaches the surface. Most is absorbed by oxygen. As the ozone layer builds each day, harsh UV-b will no longer reach the surface. Exposure to this light can cause sunburn. The symptoms of this exposure typically appear several hours after exposure.
UV-a light normally reaches the surface. This can cause plastics to polymerize, and causes skin to tan. These frequencies do not cause sunburn or cancer. A few rare people can see UV-a light. I happen to be one of them. Bees, hummingbirds, and many other critters can also see UV-a light.
3) It was our fault for depleting the ozone layer which helped protect against UV damage.
It is not possible to destroy the ozone layer, even if we wanted to.
4) We evolved as primates in the African forests. We were never supposed to spend extensive periods in direct sunlight.
So you deny the Bible once again. You believe in the Church of Evolution.
5) Once again, you are demanding that our lives be made ideal, flawless, perfect,
He doesn't what 'ideal', 'flawless', and 'perfect' even mean. He just claims he wants them.
and that everything be made for the express purpose of human comfort and convenience, irrespective of the biological, ecological, and physical needs of everything else in the universe. That is not a convincing argument.
Both of you are stuck in limited thinking, considering only this life that we live now.
These high levels of melanin in dark skin provide substantial protection from UV damage.
Did you know a black person can get sunburned? Yup. Happens all the time!
It was a free choice of homo sapiens to migrate to northern latitudes where we lost some of our melanin.
Yet another teaching in the Church of Evolution.
Made possible by fine tuning of the razor's edge balance
No razor.
Cliche fallacy.
of the fundamental parameters of physical reality, and the net zero balance of energy.
Man created natural constant.
Man create mathematics.
There is no such thing as 'physical reality'. Go learn what 'reality' means.
There is no such thing as 'net zero balance of energy'.
Buzzword fallacies.
