People tan because sunlight causes the skin to produce more melanin and darken. The tan fades when new cells move to the surface and the tanned cells are sloughed off.
Does all life on Earth require sunshine?

Do humans need the sun for survival?
We know that all plants require a certain amount of sunlight to make food and survive, through a process called photosynthesis. … Humans get our energy from the food we eat, and all of that food is derived from the energy of the sun. So, we need the sun to survive.

How long would humans survive without the sun?
A relatively simple calculation would show that the Earth’s surface temperature would drop by a factor of two about every two months if the Sun were shut off. The current mean temperature of the Earth’s surface is about 300 Kelvin (K). This means in two months the temperature would drop to 150K, and 75K in four months.
Why are plants green?
So, plants and their leaves look green because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell. The unused green light is reflected from the leaf and we see that light.
Why is sunlight important to animals?
Function of the Sun in Animals The energy from the sun is transferred from plants to animals when animals eat the plants. Animals also benefit from the sun’s effect on their bodies, because sunlight on skin produces vitamin D, which is important in the formation of strong bones.

How does lack of sunlight affect plant growth?
Without the sun, plants wouldn’t get the necessary food needed to grow, reproduce, and survive. Plants need three basic things to live: sunlight, water, and carbon dioxide. Through a process called photosynthesis, the plants use the energy from the sun to convert carbon dioxide, soil nutrients, and water into food!
