Improved technologies to combat air pollution

2013-06-07 Wszystkich nas wychowano, byśmy oszczędzali papieru, aby uratować drzewa. Dostajemy niezliczone e-maile: „Proszę, pomyśl o środowisku przed wydrukowaniem". Ruch ochrony przyrody zaczął się od wezwania do zachowanie lasów. Teraz jednak, w imię uratowania planety przed zmianą klimatu, środowiskowcy proponują olbrzymią globalną kampanię ścinania i palenia drzew i krzewów w celu zredukowania korzystania z paliw kopalnych.

During the dry season, Dhaka is one of the most polluted cities in the world. Air pollution levels during this period of the year reach 13-16 times higher than the international quality standard, and that outdoor air pollution kills 14,000of the city's residents annually.

The need to reduce air pollution in the capital may seem obvious. But using scarce resources to fight outdoor air pollution means less funding will be available from the national budget, international donors, or private citizens for other proposals that can do good.

Air pollution is a major issue around the world. It kills seven million people annually-one in every eight people that die around the world. And, of course, air pollution is a well-known and much-complained-about fact in Bangladesh. Few major global cities suffer from air pollution worse than Dhaka. During the dry season, when dust is especially bad, pollution levels can reach up to 16 times higher than the World Health Organisation's air quality guideline.
