That’s what a new study says unless nations take action now to curb air pollution.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />

</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">“Sulfur dioxide, carbon monoxide. Then we have nitrogen dioxide, ozone, and finally we have this so-called PM2.5 – particulate matter, which is below 2.5 micrometers. That’s the size of the particulate matter,” he said.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />
</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">The U.S. Environmental Protection Agency says particles of 2.5 micrometers are “small enough to invade even the smallest airways,” such as deep inside the lungs. These pollutants are not the same as those that contribute to climate change.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />
</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">He said, “The ones driving global warming are so-called greenhouse gasses like carbon dioxide and methane, for example, and ozone as well. While in this case these pollutants needed for air quality calculation are rather different. And in this case, these are traces and gasses that are more dangerous for human health.”<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />

</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">“This could be natural dust, for example, in the desert where you find a lot of particles. So there’s a very high concentration of PM2.5, or even in very polluted locations like close to a factory. When there are smoke films coming out, these generally contain [a[ high level of particles. Let’s take, for example, sulfur dioxide. These are emitted by volcanoes and at the same time it’s manmade, also emitted by factories. And in this case nowadays anthropogenic emissions are by far the major emitters of sulfur dioxide,” he said.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />
</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">India and China have rapidly growing economies, and with growth comes greater pollution. Pozzer said it’s happened before.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />
</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">“Let’s suppose for U.S. or Europe. This would have been the same during the 60s and the 70s and the 80s. Big growth in the economy, and there was the appearance of acid rains and so on. So it’s history that comes back,” he said.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />
</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">He said China, India and the Middle Eastern and North African countries should take strong action before 2025. He calls that year the “tipping point” when air pollution could start getting extremely bad.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />
</div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><span style="font-family: "Trebuchet MS","sans-serif"; font-size: 12.0pt; line-height: 115%;">While North African countries could face worsening air pollution, sub-Saharan African countries could be largely spared.<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />

So very localized hotspots like huge cities, while in general, in Africa, the air will be more than clean I would say.”<o:p></o:p></span></div><div class="MsoNormal" style="direction: ltr; text-align: justify; unicode-bidi: embed;"><br />

He says while pollution controls are expensive, they pay for themselves through better health of the population. ---VOA News<o:p></o:p></span></div></div>

Third World countries in Africa, South America and large swathes of Asia lie in almost complete darkness, barely registering any light at night in contrast to the West, apart from an amazing trail of light from Cairo running down the Nile in Egypt. Just goes to show the extent to which the West is guilty of wasting energy and polluting light on a staggering scale.Photo courtesy barcroft media ---NNN</span></div></div>
