Ironically enough, one male researcher from England used tampons to detect grey water contamination, or laundry system run off, that might be present in waterways. The tampons absorbed key signature chemicals that glow in the dark, making them easy to use and cheap. Moreover, it’s more reliable than consecrated and expensive methods.
Paris authorities have put in place 24-hour emergency measures to limit the number of cars in traffic as part of their efforts to fight the smog shrouding the city. Today (Monday, March 23) all cars with number plates that end with an even number will be banned from circulating in the Paris region, unless they’re carrying 3 or more passengers. Clean cars will also be allowed.
The conservative Canadian government headed by Prime Minister Stephen Harper has consistently moved the country away from sustainable practices and environmental accountability. In 2011, the government came under fire after it withdrew Canada from the Kyoto protocol, an international agreement which commits its parties by setting internationally binding emission reduction targets. It also disbanded the National Round Table on the Environment and the Economy in 2012, a panel tasked with reporting to the government Canada’s greenhouse gas emissions. While the government has also taken some measures aimed at curbing emissions, these have been largely insufficient. Disappointed, 71 Canadian scientists have authored their own climate policy recommendations for the nation.
Saul Luciano Lliuya is a farmer from Peru whose home in the floodpath of the Palcacocha lake which has been swelling with glacial melt-water for the past few decades. Because Lliuya feels “acutely threatened” by the lake, the farmer is now prepared to take one of Germany’s biggest producers of brown coal energy to court and demand compensation. This would make it the first such legal claim in Europe where a company is summoned to pay for its historical role in driving emissions.
It’s not just Chinese air that’s dirty and polluted, it’s the coastline too. According to the Chinese State Oceanic Administration (SOA) some 41,000 sq km of coastline is polluted with inorganic nitrogen, reactive phosphate or oil, to name a few. This amounts to roughly 81% of its entire coastline, which actually marks a mild improvement over 2013 despite an increase in ecological incidents such as red tides and algal blooms.
Switching massively to electric cars could save UK drivers up to £1,000 a year on fuel costs, reducing oil imports by almost half by 2030; a similar trend could be replicated in other countries in Western Europe or in the US.
When she was pregnant, former Chinese news anchor Chai Jing got some tragic news – her unborn daughter was diagnosed with a tumour. She immediately quit her job, and soon started working on a documentary focusing on China’s pollution problem (especially smog). Now, her self-financed documentary, for which she paid $200,000 took the country by storm, with 75 million hits on the day it was released on Chinese video streaming sites and over 250 million views now.
India is among the most polluted country in the world, a direct consequence of its growth-orientated policy. Despite economic growth, the health of Indians is suffering significantly. According to researchers at University of Chicago, Harvard and Yale, pollution is directly responsible for shortening the lives of 660 million Indians who live in sensitive areas by three years on average. In total 2.1 billion life-years
When we’re talking about CO2 emissions and global warming, we generally mean atmospheric CO2 – where the gas is spewed and generates the greenhouse effect, warming our atmosphere and subsequently, our planet. But a new study conducted by US researchers found that CO2 actually warms the Earth’s crust directly; the more CO2 we emit, the hotter our planet will get.
After scientists discovered a huge hole in the ozone layer above the Antarctic, an emergency UN panel banned the use of chlorofluorocarbons (CFCs) in 1987. These build up in the atmosphere, react with the triple oxygen molecule and break it down. Since then, ozone has thankfully replenished, thought it might take decades before it reverts to pre-1980 levels. Progress is slow because there are still some plants through out the world who illegally use CFCs (the stuff that used to go into refrigerants or deodorants), but also because there are other ozone-depleting chemicals out there – some recognized, others new and extremely dangerous. One class of chemicals that has been allowed in the industry since the Montreal Protocol, despite the danger it posses to ozone, is made up of so-called ‘very short-lived substances’ (VSLS) which breakup in under six months. A new study, however, found that these have dramatically increased over the past couple of years and despite their short reaction times, these could prove to be extremely dangerous.
