World Environment Day
5 June marks World Environment Day, which was established in 1972 by the United Nations to raise people's awareness of our vulnerable environment and other environmental issues.
This year's World Environment Day is hosted by China, with a theme on air pollution, a world-wide issue that is most prominent in the Asia-Pacific region. In this region, air pollution directly or indirectly causes an estimated 4 million deaths (from the 7 million people world-wide). In some major Chinese cities, the air can sometimes be so polluted that even on a ‘clear' sunny day people hardly see the sun.
Nevertheless, the Chinese government is taking measures to improve the air quality, which is already observed over the last few years from space by dedicated air quality satellite sensors.
The city can be seen as a grey area in the top-middle part of the image. At the bottom of the image the northern part of the Hainan island is visible.
