SUNSCREEN in UV

Many of those "chemicals" are not exclusively an issue of sunscreens like parabens but creams and such in general, physical sunscreens contain nanoparticles which can if small enough be absorbed by the skin and in an aquatic environment catalyse to form substances very toxic to all life.. The thing is that we should be exposing to the sun in moderation, and not stay out so long to get sunburned. Its an issue of the lack of moderation in contemporary humans. You do not go to the beach all day and then use a ton of sunscreen. That is not only bad for you as all "chemical" sunscreens (and many/most "physical") contain these carcinogenic substances but whats perhaps even more urgent, is that it is HORRID for the environment both because of all the cream that gets washed away from the skin into the ocean and waste water when showering AND because of the PLASTIC PACKAGING. The third issue is that most Americans are vitamin D deficient and vitamin D can only be produced when exposed to UVB light (which is exclusive to midday) and by avoiding it you are literally giving yourself a much higher chance of most types of skin cancer and depression.
