Many people believe that the city is too polluted, moving to the countryside will be a safer solution. But is that really the case?
In the face of serious pollution in big cities, many people think of going to the mountains or the countryside and living better. They are fresh, close to nature, smokeless, noisy, have fewer accidents .
Only thing, the reality does not seem to be so.
It is easy to see that the pollution of dust, noise in the city is the main cause of diseases such as asthma, allergies, depression . But in return, emergency services, health care here are timely. time and quality.
Through the survey, social researchers also realized that: Urban residents in big cities are less obese, less likely to commit suicide and die less from accidents. Especially, the treatment of the elderly is extremely good. Most seniors live happily, healthily, and longevity.
The safest environment is a clean city + close to nature.
The pollution situation in big cities like New Delhi (India), Seoul (Korea), Bangkok (Thailand) . makes us forget that not all urban areas in the world are unsafe. Visit the cleanest cities, such as Wellington (New Zealand), Kobe (Japan), even New York (USA) . you will find them "most worth living".
Many people just say, go to the countryside but stay or take care of your children for "good health". Indeed, in "hometown" not so cars, dusty, noisy. However, cleanliness also depends on the region.
Urban areas are very "polluted", but provide the best working and health conditions.
Take the Indian example. Statistics show that the country is heavily polluted by air pollution, estimated to take away about 1.5 million residents each year. But did you know that 1.1 million people die in rural areas, not in cities?
The reason is that most rural people are exposed to "copper smoke" , wood or cow dung. According to 2015 statistics, up to 75% of deaths from air pollution in India are in rural areas.
Although the countryside is quiet, pollution of fertilizers and pesticides is not minor
The earth is large (510,100,000 km2), but there are not too many places where people can live. In fact, we only have 4 basic options: City, countryside, mountain, sea.
Compared to the city with various types of pollution, or the countryside may have a lot of pesticides, fertilizer pollution . the mountains seem to be safer.
The benefits of the mountains are many trees. In all environmental conditions, many trees are still the cleanest. Plants are very good at absorbing emissions, cooling, even preventing noise pollution.
The "most stable" mountainous areas are in the height of 1,500-2,500m above the sea level, but it is also troublesome when forest fires.
But miserably, the forest sometimes burns. In the era of global warming today, everywhere has the potential for forest fire. Every fire produces toxic fumes. Depending on the size of the fire, the amount of smoke will melt quickly or hang around for months.
And yet, the smoke is still free to move. Whether the fire location is Indonesia, neighboring countries such as Singapore, Malaysia, Thailand . still affected. Smoke has been discovered from South America and southern Africa throughout the Southern Hemisphere.
Most pollutant material is heavier than air. The higher you go, the less polluted it will be. But please do not rush to conclude that living up high! The higher it gets more solar radiation. The harmful effects of ultraviolet rays can, in many ways, be more serious than the usual pollution.
To avoid ultraviolet rays, it is recommended to choose a house in moderate height, about 1,500-2,500 meters above sea level.
Over 2,500m above sea level is "dead to the Sun".
The best color for human mental health is blue. The more we are "bathed" in the green space, the less stressed and more insecure we become.
Earth has half the surface of the blue sea. There is no "green space" larger than the sea, and of course living near the ocean is the best. In addition, the locations near the water such as lakes, rivers, streams . in blue also have a similar "mental stability" .
The sea reduces stress, but it is also easily swallowed by waves.
Unfortunately, the sea is also double-sided - intense and mellow. Every time a thunderstorm or tsunami strikes people. Even the "soft" tide that swells up and down is full of dangers.
Human health depends on many factors. Except for environmental conditions that are financially, psychologically, genetically . If every fresh air is "needed and sufficient", we have just moved to pristine forests or coasts.
In fact, people tend to flood into the city , regardless of whether it's the cleanest or most polluted city. Only a very small amount goes "in the opposite direction", from the city to the suburbs, the countryside, the mountains or the sea.
The reason is simple: The city is full of everything a person needs. From public transport to wealth opportunities, health care, education, welfare . all are "convenient". Rich people think about enjoyment. The poor cannot escape the anxiety of survival. Even though we know we have to trade with the risk of declining health, most of us still have to choose the city because of "a piece of rice".
If you "insist" to point out the best living environment, it's a clean city + close to nature (forest or sea). For example, Sydney (Australia) or Helsinki (Finland) for example.
