India Beats China As Worst Air-Polluted Country On Earth
India now has the world’s worst air pollution. They have beaten China. Specifically, it is New Delhi, India’s capital that has the worst air pollution on Earth.
Industrialization, coal-fired power plants, and low regulation have made the air pollution in India so much worse. Technology Review has reported that there have been 1.1 million deaths recorded last year due to air pollution in India. The country has been tied with China as having deadly air pollution. India’s rapid industrialization, too much use of coal for energy, growing population, and an ageing populace that is affected by air pollution are the factors why there are so many deaths.
Pollution Has Worked Its Way Down To The World’s Deepest Waters
The Mariana Trench in the northern Pacific is the deepest part of the world’s oceans. You might think a place that remote would be untouched by human activity.
But the Mariana Trench is polluted.
At its deepest — about 7 miles down — the water in the trench is near freezing. The pressure would crush a human like a bug. Scientists have only recently explored it.
Among them is biologist Alan Jamieson of Newcastle University in England. His team dropped what they call a mechanical “lander” down into the trench. It had cameras and water samplers and some baited traps. They didn’t really know what they’d find.
When the lander surfaced, the traps contained amphipods — shrimplike crustaceans. That wasn’t terribly surprising, as amphipods are known to live at great depths. But bringing them back from the Mariana Trench was a rarity, and Jamieson thought there might be something to learn from them. He took the creatures to an environmental scientist.
The amphipods were contaminated with PCBs — polychlorinated biphenyls — toxic chemicals used for decades in industry, as well as other industrial pollutants known as persistent organic pollutants.
Every sample we had,” Jamieson says, “had contaminants in it at very high or extraordinarily high levels. How high? He compared the contamination level in his Mariana amphipods to crabs living in waters fed by one of China’s most polluted rivers, as well as amphipods from other parts of the world. “And what we were finding in the deepest place in the world were (levels) hugely higher, 50 times in some cases,” he says.
