Earth is facing a big problem that is global warming or what, global warming could lead to climate change and have a very harmful effect on human health.
Various types of air pollution can damage the ozone layer then sunlight can directly expose the earth without any protection. This causes climate change which was originally cool, dry and over time become detrimental to health.
As reported by prevention, Sunday (01/27/2013) The following five issues that threaten human health due to extreme climate change, among others:
1. Obesity
Global warming causes climate becomes drier and increasingly long periods, it can affect agriculture and plantations. The number of healthy foods like vegetables, fruits and milk will be depleted and the price can soar.
As a result, many people turn to unhealthy foods and tend to contain simple carbohydrates. It can actually cause obesity, according to research in the American Journal of Public Health.
2. Malnutrition
Besides staple food prices higher, climate change may lead to less nutritious food sources grow in less fertile land. According to the National Climate Assessment in the United States, increased levels of carbon dioxide can reduce nitrogen and protein content of grain as well as lower levels of calcium, iron, and vitamins in fruits and vegetables.
The food was poor nutrition can lead to malnutrition in children can impair growth.
3. Disruption of hormone production
Higher temperatures cause the weeds grow faster, so it would be a lot of herbicides used by farmers to protect their food crops. Herbicides such as Roundup are most often used by farmers to control weeds, is known to disrupt hormones.
4. Fish contaminated with mercury
A recent study suggests that climate change may exacerbate the level of mercury in the food chain. One reason is that global warming is causing Arctic ice cap divert mercury into the air as a gas.
The gas can affect the seawater and accumulate in the fatty tissue of fish. High levels of mercury in fish can lead to a variety of risks such as heart problems diseases and disorders of pregnancy.
5. Numbers increased birth defects
A number of studies have found that a high fever during certain critical stages when pregnancy can lead to birth defects in babies. Apparently, heat waves and high temperatures due to climate change has the same effect. A study recently conducted notes that pregnant women who are exposed to heat waves are more likely to have a baby with birth defects such as cataracts.
To prevent health problems from fifth to extreme climate change, you need to keep the environment in order to avoid global warming, for example by not cutting down trees, saving electricity, reducing the use of motor vehicles and the use of air conditioning.
