Yes you are spot on. We do not need to eat animals in order to survive, and by being in the sun in a smart way and not basking hours at a time we won't need that much sun screen.
But as the sun gets brighter you do need some prodection and it's reeally important to look at the ingredients and buy from a source you know you can trust.
As for eating right away after you Wake up I totally agree that is a no go. I'm usually starving right after I come out of bed but drinking some water helps and eating some fruits before the larger breakfast also is a good way to not chock your body with a heavy porridge the first thing you eat in the morning :)
Really good post =)
