❓ How does marine pollution affect human life?

❓ How does light pollution affect human health?

Because more of us are sleeping in overly lit nights, light pollution is being investigated as a interfering, aggravating factor that suppresses natural melatonin levels in humans at night. This suppression simply pulls out the stops to cancer cell growth. The hormone melatonin normally impedes cancer cell growth and can even cause cancer cell death.

Finally, light pollution can affect the effectiveness of visual communications and reproductive behaviour. Bioluminescent species, i.e. species capable of producing and emitting their own light, are particularly affected, such as fireflies and glow worms that use light signals to attract their partners.

However, like carbon dioxide emissions and plastic, too much of a good thing has started to negatively impact the environment. Light pollution, the excessive or inappropriate use of outdoor artificial light, is affecting human health, wildlife behavior, and our ability to observe stars and other celestial objects. That Earthly Sky Glow

Impact of Light Pollution on Health Light pollution also has clear health and environmental detriments, including harming abilities to sleep, increasing possible cancer, and harming animal behavior, including migration. Linkages with health and wildlife have been a key focus in the geography literature.

The spread of artificial lighting means most of us no longer experience truly dark nights. Research suggests that artificial light at night can negatively affect human health, increasing risks for obesity, depression, sleep disorders, diabetes, breast cancer and more. Circadian Rhythm and Melatonin

Excessive light causes light pollution, and the harmful effects of light pollution are affecting the human body in many ways. Light pollution may cause various health issues to our body such as irritation in eyes, redness in eyes and some severe cases permanent darkness in eyes, etc.

Too much light can damage human eyes and even harm the hormone melatonin which is responsible for regulating diurnal and nocturnal visions. This can result in sleep disorders and other health implications such as stress, exhaustion, headaches, increased anxiety, and some forms of obesity may develop.

Photosynthesis, the process by which plants grow, depends on light and dark. And all animals depend on plants for their survival. One of the less frequently reported impacts of human activity on the environment is the presence of artificial light. Lighting disrupts photosynthesis and the activities of insects, birds and other animals.

Humans have radically disrupted this cycle by lighting up the night. 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.

Light pollution is artificial light that falls on a habitat and/or ecosystem. In the Arctic, climate change has thinned the ice enough to allow artificial light from vessels to penetrate the dark ocean. As a result, organisms that normally depend on the dark become disturbed by the unexpected and unusual brightness.
