The sun has many disadvantages, including health dangers from overexposure, scorching of plants and low energy production during certain hours. The sun's disadvantages affect humans, animals, plants and energy production.
The main disadvantage of the sun is overexposure in both humans and animals. Too much sun exposure causes sunburn on exposed skin, and humans and animals are both susceptible to sunburn. Over time, multiple severe sunburns weaken the skin, causing a leathery appearance and bruising.
Another negative effect of sun exposure is the increased risk of skin cancer. Humans are mostly susceptible to this, but animals can be affected too. According to the Cleveland Clinic, many doctors believe that most instances of skin cancer can be avoided simply by taking preventative measures against prolonged sun exposure.
Plants can be affected by overexposure too. The result is scorching, which can kill the plant. Too little or too much sunlight produces negative effects on plant growth. Sun damage to crops can result in financial hardship for farmers and supply issues for consumers.
The sun has several disadvantages in relation to solar power. Complications due to limited daylight hours, cloudy conditions, and the ever-moving position of the sun cause solar power production levels to fluctuate constantly. This makes it difficult to use the sun as a reliable power source.
