How has the sun impacted our lives?
402497
Considering that very nearly 100% of all the energy that allows us to live, work and play comes from the sun, and also supports nearly every living organism on the planet, I'd say the sun has had a pretty major impact on all life on Earth.

In our lifetimes it will be purely because of the filtering effects of the atmosphere and clouds. When there is dust, water, chamicals or ice in the atmosphere the colours let through will change, just like putting a coloured scarf over a lamp. \n\nWhen the sun is low in the sky the high frequencies are scattered, allowing more of the red-yellow light to reach us.\n\nAlthough the sun is predicted to change colour and grow, it will be over bilions of years.

Ultra-violet rays from the sun.  They cause skin cancer, sunburn, and more.

The sun tends to lighten all pigments.  That's why it makes hair lighter (as well as construction paper, stuffed animals, and most other things you leave in direct sun light).  It's a chemistry thing that I sort of vaguely understand, but I'm not going to try to explain it.\n\nHowever, the UV radiation stimulates the cells in your skin to release extra pigment to protect your skin from the harmful effects of the radiation (sunburn, DNA damage, etc.).  The extra pigment makes your skin darker.  This part I could explain in a lot more detail if you want to hear it :-P

Yes, we have affected and been affecting our Mother Earth largely!\nEvery road disturbs the natural ways of animal movements.\nOur use of certain chemicals destroy sections of the atmosphere.\nCreation of cement cities lowers the natural beauty!\nNuclear tests are changing regions.\nProfessional fishing eliminates kinds of sea life.\nand so on!

You really do need to see a doctor for this, to rule out any serious conditions.  \n\nIt may very well be you are just extra-sensitive to the sun, and to heat.  Some people are, regardless of race.  Also, if you are on any medications, ask your pharmacist if any of them might cause an increased sensitivity to sunlight/heat.\n\nOne reason you need to see a doctor is that a disease called Lupus makes people very sun-sensitive.  There are other symptoms involved as well, and a doctor will be able to tell you if you have it or not.  If you do, it is important to have appropriate ongoing treatment so it doesn't get worse and so that it affects your life as little as possible.  If your doctor determines you do not have lupus, s/he will at the least be able to give suggestions for enduring hot sunny weather more comfortably.

Exposure to sun is important for people because it triggers the production of vitamin D, necesary in the absotion and balance of calcium (which is basic for life). Black people in poorly lit places (say finland...) have calcium problems. \nThe amount of energy necesary for this, however is not big. The problem with sunlight is that it has a lot of UV radiation that can produce mutations in the DNA. if the exposure is too strong, the amount of mutation will be so big that the cell will simply die (this is when you peel at the beach, layers of skin cells died and falled down). this mutations in the skin cells DNA can produce many deseases, beeing cancer the most conspicous one. \nMelanin, the skin pigment, is a very good absorber of UV radiation, so black people don't have problems in high radiation places, whereas whities need to be extremely carefull.

Well, in our case it does. Our town was very much excited when a total solar eclipse more than ten years ago, specifically October 25, 1995. I was a child back then but the hype turned me on and in fact, it was a wonder seeing the moon cover the sun from a colored film strip. It was only worth for a couple of minutes but it was awesome! I could also see that the sky became darker a bit. Much like a once in a lifetime affair.

Yes.  And damage is actually already done prior to the burn.  The human body requires a mere 15 minutes per week of natural sunlight for the amout of vit. D it gives and the body needs.\n\nAny prolonged sun exposure is detrimental to your skin.  People who have never even been burned but just naturally tan get skin cancer, as well as premature wrinkling and even the leathery skin.

Skin cancer, sun damage, wrinkles.

yes it's the worst timing to be exposed to direct sunlight and it increases the chances of skin cancer

If there was no Sun, there would be very little life on Earth. Sunlight supports almost all life on Earth via photosynthesis, and, via heating from insulation, drives climate and the weather cycle.

Yes many people have been affected by this. Hope this answer helps

High frequency radiation like ultraviolet radiation contains more energy, and it can damage the DNA in your cells, causing cancer. \n\nIt can also cause bad burns.

UV radiation from the sun has always played important roles in our environment, and affects nearly all living organisms. Biological actions of many kinds have evolved to deal with it. Yet UV radiation at different wavelengths differs in its effects, and we have to live with the harmful effects as well as the helpful ones. Radiation at the longer UV wavelengths of 320-400 nm, designated as UV-A, plays a helpful and essential role in formation of Vitamin D by the skin, and plays a harmful role in that it causes sunburn on human skin and cataracts in our eyes. Radiation at shorter wavelengths of 290-320 nm, designated as UV-B, causes damage at the molecular level to the fundamental building block of life— deoxyribonucleic acid (DNA).

yes, the sun is a good example

You asked for it! Ha ha ha ha!\n\nWhat is the sun? Read this.....\nI  INTRODUCTION \n\nSun, closest star to Earth. The Sun is a huge mass of hot, glowing gas. The strong gravitational pull of the Sun holds Earth and the other planets in the solar system in orbit. The Sun’s light and heat influence all of the objects in the solar system and allow life to exist on Earth. \n\nThe Sun is an average star—its size, age, and temperature fall in about the middle of the ranges of these properties for all stars. Astronomers believe that the Sun is about 4.6 billion years old and will keep shining for about another 7 billion years. \n\nFor humans, the Sun is beautiful and useful, but also powerful and dangerous. As Earth turns, the Sun rises over the eastern horizon in the morning, passes across the sky during the day, and sets in the west in the evening. This movement of the Sun across the sky marks the passage of time during the day (see Sundial). The Sun’s movement can produce spectacular sunrises and sunsets under the right atmospheric conditions. At night, reflected sunlight makes the Moon and planets bright in the night sky. \n\nThe Sun provides Earth with vast amounts of energy every day. The oceans and seas store this energy and help keep the temperature of Earth at a level that allows a wide variety of life to exist. Plants use the Sun’s energy to make food, and plants provide food for other organisms. The Sun’s energy also creates wind in Earth’s atmosphere. This wind can be harnessed and used to produce power.\n\nWhile it lights our day and provides energy for life, sunlight can also be harmful to people. Human skin is sensitive to ultraviolet light emitted from the Sun. Earth’s atmosphere blocks much of the harmful light, but sunlight is still strong enough to burn skin under some conditions (see Burn). Sunburn is one of the most important risk factors in the development of skin cancers, which can be fatal. Sunlight is also very harmful to human eyes. A person should never look directly at the Sun, even with sunglasses or during an eclipse. The Sun influences Earth with more than just light. Particles flowing from the Sun can disrupt Earth’s magnetic field, and these disruptions can interfere with electronic communications.\n\nII  PHYSICAL CHARACTERISTICS \n\nThe Sun is large and massive compared to the other objects in the solar system. The Sun’s radius (the distance from its center to its surface) is 695,508 km (432,169 mi), 109 times as large as Earth’s radius. If the Sun were hollow, a million Earths could fit inside it. The Sun has a mass of 1.989 × 1027 metric tons. This number is very large. Written out, it would be the digits 1989 followed by 24 zeroes. The Sun is 333,000 times as massive as Earth is. Despite its large mass, the Sun has a lower density, or mass per unit volume, than Earth. The Sun’s average density is only 1.409 g/cu cm (1.188 oz/cu in), which is a quarter of the average density of Earth.\n\nThe Sun produces an enormous amount of light. It generates 3.83 × 1026 watts of power in the form of light. In comparison, an incandescent lamp emits 60 to 100 watts of power. The temperature of the outer, visible part of the Sun is 5500°C (9900°F). \n\nFrom Earth the Sun looks small, because it is far away. Its average distance from Earth is 150 million km (93 million mi). Light from the Sun takes about eight minutes to reach Earth. This light is still strong enough when it reaches Earth, however, to damage human eyes when viewed directly. The Sun is much closer to Earth than any other star is. The Sun’s nearest stellar neighbor, Proxima Centauri (part of the triple star Alpha Centauri), is 4.3 light-years from our solar system, meaning light from Proxima Centauri takes 4.3 years to reach the Sun. The Sun is so much closer to Earth than all other stars are that the intense light of the Sun keeps us from seeing any other stars during the day.\n\nA  Importance to Earth \n\nEarth would no
