Power companies use a variety of processes to create electricity, and not all processes affect the environment in the same way for example, coal is a much more environmentally problematic source of energy than solar power, which has minimal environmental effects. Plants and animals depend on earth’s daily cycle of light and dark rhythm to govern life-sustaining behaviors such as reproduction, nourishment, sleep and protection from predators scientific evidence suggests that artificial light at night has negative and deadly effects on many creatures including amphibians, birds, mammals, insects and plants. The sun warms our planet - the surface, the atmosphere and bodies of water it allows this mother and young boy to enjoy warmth and light during an outing at the beach photo taken in may in the outer banks, nc.
Changing from incandescent light bulbs to energy star qualified light bulbs, however, can greatly reduce the environmental impact of your home or business saving energy the energy savings of cooler-burning bulbs, including cfl and led, can have a significant impact on your utility bills and on making your home greener. The sun's corona the sun is the dominant source for visible-light waves our eyes receive the outer-most layer of the sun's atmosphere, the corona, can be seen in visible light. Radiation at the longer uv wavelengths of 320-400 nm, called 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.
How light affect our planet: process writing thomas tse october 31, 2012 nowadays due to light pollution, it is hard to find a place in hong kong that can look at the stars clearly it means that the light has disturbed our planet already few types of animals can’t figure out that it’s morning or night. Keep reading to answer these questions on how light affects the growth of a plant how light affects the growth of a plant all things need energy to grow we get energy from the food we eat plants get energy from light through a process called photosynthesis this is how light affects the growth of a plant. While animals have been shown to be disturbed by artificial light at night, its effects on humans, it is argued, range from discomfort and glare to sleep deprivation and cancer testtube plus is built for enthusiastic science. To assume that other living organisms on this planet are just going to adapt to our newly created lighting schedules for commericial convenience is apathetically ignorant and insane unfortunately, it is far, far easier to setup a badly installed light outside than it is to understand the negative effects it casts down-light from it.
The sun warms our planet, heating the surface, the oceans and the atmosphere this energy to the atmosphere is one of the primary drivers our weather our climate is also strongly affected by the amount of solar radiation received at earth. Light pollution effects on wildlife and ecosystems “ when we add light to the environment, that has the potential to disrupt habitat, just like running a bulldozer over the landscape can” — chad moore, formerly of the national park service.
Wavelengths of visible light all electromagnetic radiation is light, but we can only see a small portion of this radiation—the portion we call visible light cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum. (uv-b includes light with wavelengths down to 280 nm, but little to no radiation below 290 nm reaches the earth’s surface) uv-b causes damage at the molecular level to the fundamental building block of life— deoxyribonucleic acid (dna. This is shorter than wavelengths of visible light, which are 400 to 700 nm people and plants live with both helpful and harmful effects of ultraviolet (uv) radiation from the sun (photograph courtesy jeannie allen) uv radiation from the sun has always played important roles in our environment, and affects nearly all living organisms.
While animals have been shown to be disturbed by artificial light at night, its effects on humans, it is argued, range from discomfort and glare to sleep deprivation and cancer.
At the extreme end of the spectrum, light pollution can even affect seasonal patterns last year, it was found that light pollution caused spring to come a full week earlier than normal, having unpredictable and potentially irreversible effects on the flora and fauna of our planet. The radiation given off by the sun affects the earth's climate patterns and its overall temperature solar activity, such as solar flares or sunspots, increases the amount of radiation that is given off by the sun and causes the earth to have dramatic changes in temperature solar radiation warms the surface of the planet during the day.
