Cities are filled with light pollution, so if you want to see your city in its natural light for longer, it’s best to stay away from the city lights.
This is a very important issue, as it’s estimated that as many as 30 million people are in areas with low light levels.
Many of these cities are located on the Pacific coast, in the Northern Hemisphere, in Asia, in Africa, and even in the Middle East.
So the issue is not just a matter of pollution levels but also how these lights are used.
For example, there are over 2,000 municipal lights in Tokyo alone, but these are only the most visible lights.
The rest of the cities are not visible in the sky, and so they need to be kept on, said Joon Hwang, a senior researcher at the National Institute of Environment and Technology in Japan.
This means that the use of light pollution is a bigger problem in urban areas than in other parts of the world, which are often used as a natural light source.
“We need to use less light and more energy.
We need to reduce the intensity of the lights,” he said.
It also means that urban areas need to develop better urban light infrastructure, such as lighting systems and lighting displays.
“People are more aware of the need for lighting, and we need to create a culture of light in cities,” Hwang added.
However, the number of light-polluted cities is increasing, and is now the second biggest contributor to CO2 emissions in the world.
In addition to cities, there is also an increase in light pollution in rural areas, particularly in rural Japan.
For the second consecutive year, Japan experienced a drop in light levels in rural parts of its main island, Kyushu, which accounted for around a third of the country’s total CO2 output.
Hwang said that the region has also been hit by a new pandemic.
“It was expected that light pollution would decrease, but in the first three months of 2016 it increased by almost 50%,” he told Al Jazeera.
“That’s a very worrying trend, because it means that rural areas are more vulnerable.”
This means more rural areas have to face the threat of increasing light pollution.
“When we look at the data we have on the level of CO2 pollution in the area, we see that the number is increasing year-on-year,” Hwa said.
“If this continues, it means the rural areas of Japan are at higher risk of serious climate change.”
According to a 2016 report from the World Health Organisation, light pollution caused by household lights and outdoor air pollution from cars and other vehicles accounted for 60% of CO3 emissions from 2013 to 2015.
It’s estimated about 80% of the CO2 in Japan comes from the industrialised areas, such the industrial parks, which account for about 30% of emissions.
In other countries, light emissions from industrial facilities, such factories, are usually not linked to climate change.
“In some countries like Germany, they have very strong pollution laws, so they have no restrictions on industrial pollution,” Hwansaid.
“But in Japan, there’s no regulation on industrial emissions.”
The country is not alone.
The International Energy Agency, an international body which tracks emissions of pollutants from industrial activities, found that industrial emission levels in the United States are increasing by 5% a year.
A 2015 study by the University of New South Wales found that there were more than a million industrial emissions in Australia in 2015, and that the US has one of the highest concentrations of industrial emissions per head in the developed world.
It has been estimated that around 1,000 jobs could be lost if all of the existing CO2 was removed from the atmosphere.
