Continuous Daylight

Continuous Daylight

What if there was no day? Only continuous night?

I was trying to find a site that listed the consequences of no daylight and only continuous night time. What do you think would happen? Also if you know of any good sites to check out, please list them here. Thanks in advance!

well odviously plants and algea and such couldnt survive because of photosynthesis. If the plant's couldnt survive then all the herbivores would either have to evolve or die out as well. some people could become depressed from the lack of sunlight, it's called season affective disorder (http://www.clevelandclinic.org/health/health-info/docs/2300/2361.asp?index=9293)
people would also suffer from vitamin D deficiencies since your body requirese sunlight to produce it and there's no good way to take vitamin D that would come close to the amount you should get. The adverse effects are broad, it can inhibit calcium absorption, and can cause osteoperosis, rickets, breast and colon cancer, depression, schizophrenia, psoriasis, and many other problems.

Also I remember reading a paper on an experiment someone did where they placed people in a deep cave with no sunlight to study the effects. Unless I'm remembering incorrectly people's sleeping schedules were off but more regular than in a light environment.
