Overpopulation, overconsumption – in pictures. How do you raise awareness about population explosion? If words are not effective enough to deal with the ominous climate emergency....maybe these stark, disturbing photos will! Guardian1 Apr 2015

Twigs, other plant matter, and Ice Age animal parts—bison jaws, horse femurs, mammoth bones—spilled onto a beach that sucked at Zimov’s boots. “I love Duvanny Yar,” he said as he yanked fossils from the muck. “It is like a book. Each page is a story about the history of nature.” Few understand this threat better than Zimov. From a ramshackle research station in the gold-mining outpost of Cherskiy, about three hours by speedboat from Duvanny Yar, he has spent decades unearthing the mysteries of a warming Arctic. Along the way, he has helped upend conventional wisdom—especially the notion that the far north, back in the Pleistocene ice ages, had been an unbroken desert of ice and thin soils dotted with sage.Instead, the abundant fossils of mammoths and other large grazers at Duvanny Yar and other sites told Zimov that Siberia, Alaska, and western Canada had been fertile grasslands, rich with herbs and willows. As these plants and animals died, the cold slowed their decomposition. Over time, windblown silt buried them deep, locking them in permafrost. The upshot is that Arctic permafrost is much richer in carbon than scientists once thought.

Now new discoveries suggest that the carbon will escape faster as the planet warms. From the unexpected speed of Arctic warming and the troubling ways that meltwater moves through polar landscapes, researchers now suspect that for every one degree Celsius rise in Earth’s average temperature, permafrost may release the equivalent of four to six years’ worth of coal, oil, and natural gas emissions—double to triple what scientists thought a few years ago. Within a few decades, if we don’t curb fossil fuel use, permafrost could be as big a source of greenhouse gases as China, the world’s largest emitter, is today. We aren’t accounting for that. The UN’s Intergovernmental Panel on Climate Change has only recently started incorporating permafrost into its projections. It still underestimates just how wide Pandora’s freezer could swing open—and how much havoc that could unleash. Permafrost’s potential to warm the planet is dwarfed by our own. But if we hope to limit warming to two degrees Celsius, as 195 nations agreed to during the 2015 Paris talks, new research suggests we may have to cut emissions eight years sooner than IPCC models project, just to account for the thawing that will be going on.

Across nine million square miles at the top of the planet, climate change is writing a new chapter. Arctic permafrost isn’t thawing gradually, as scientists once predicted. Geologically speaking, it’s thawing almost overnight. As soils like the ones at Duvanny Yar soften and slump, they’re releasing vestiges of ancient life—and masses of carbon—that have been locked in frozen dirt for millennia. Entering the atmosphere as methane or carbon dioxide, the carbon promises to accelerate climate change, even as humans struggle to curb our fossil fuel emissions. It is perhaps our least appreciated reason to hasten a transition to cleaner energy: To reach whatever goal we set to combat warming, we’ll need to move even faster than we think. Permafrost—ground that remains frozen year-round—is capped by a few feet of dirt and plant detritus. Called the active layer, this soil normally thaws each summer and refreezes in winter, protecting permafrost from rising heat above. But in the spring of 2018, a crew working for Nikita found that dirt near the surface around Cherskiy had not iced up at all during the long dark polar night. That was unheard of: January in Siberia is so brutally cold that human breath can freeze with a tinkling sound that the indigenous Yakuts call “the whisper of stars.” The Soviets used to land heavy planes on the Kolyma. Soil 30 inches down should have been frozen. Instead it was mush.

“Three years ago, the temperature in the ground above our permafrost was minus 3 degrees Celsius [27 degrees Fahrenheit],” Sergey Zimov said. “Then it was minus 2. Then it was minus one. This year, the temperature was plus 2 degrees.” On one level that’s not surprising. Earth’s five warmest years since the late 19th century have come since 2014, and the Arctic is warming more than twice as fast as the rest of the planet, as it loses the sea ice that helps chill it. In 2017 tundra in Greenland faced its worst known wildfire. Days before we landed in Siberia, thermometers in Lakselv, Norway, 240 miles above the Arctic Circle, recorded a blistering 32 degrees Celsius, or 90 degrees Fahrenheit. Arctic reindeer hid in road tunnels for relief.Permafrost temperatures globally have been rising for half a century. On Alaska’s North Slope, they spiked 11 degrees Fahrenheit in 30 years. Localized thawing of permafrost, especially in villages where development disturbs the surface and allows heat to penetrate, has eroded shorelines, undermined roads and schools, cracked pipelines, and collapsed ice cellars where Arctic hunters store walrus meat and bowhead whale blubber. Warm summers are already warping life for Arctic residents.

What the Zimovs were documenting in 2018, though, was something different, with implications beyond the Arctic: a wintertime thaw. The culprit, paradoxically, was heavy snow. Siberia is dry, but for several winters before 2018, thick snow had smothered the region. The snow acted like a blanket, trapping summer heat in the soil. At a research site 11 miles from Cherskiy, Mathias Goeckede of Germany’s Max Planck Institute for Biogeochemistry found that snow depth had doubled in five years.

The Dark Side of Fast Fashion.....According to an analysis by Business Insider, fashion production comprises 10% of total global carbon emissions, as much as the emissions generated by the European Union. The industrydries up water sources and pollutes rivers and streams, while 85% of all textiles go to dumps each year. Even washing clothes releases 50 0,000 tons of microfibres into the ocean each year, the equivalent of 50 billion plastic bottles.The Quantis International 2018 report found that the three main drivers of the industry’s global pollution impacts are dyeing and finishing (36%), yarn preparation (28%) and fibre production (15%). The report also established that fibre production has the largest impact on freshwater withdrawal (water diverted or withdrawn from a surface water or groundwater source) and ecosystem quality due to cotton cultivation, while the dyeing and finishing, yarn preparation and fibre production stages have the highest impacts on resource depletion, due to the energy-intensive processes based on fossil fuel energy. According to the UN Framework Convention on Climate Change, emissions from textile manufacturing alone are projected to skyrocket by 60% by 2030. The time it takes for a product to go through the supply chain, from design to purchase, is called lead time. In 2012, Zara was able to design, produce and deliver a new garment in two weeks; Forever 21 in six weeks and H&M in eight weeks. Newer industry player Shein, a major Chinese fast fashion company, has garments ready to be sold in just 10 days. This results in the fashion industry producing obscene amounts of waste. 

2. Microplastics - Furthermore, brands use synthetic fibres like polyester, nylon and acrylic which take hundreds of years to biodegrade. A 2017 report from the International Union for Conservation of Nature (IUCN) estimated that 35% of all microplastics – tiny pieces of non-biodegradable plastic – found in the ocean come from the laundering of synthetic textiles like polyester.......read on https://earth.org/fast-fashions-detrimental-effect-on-the-environment/
