We can do without plastic packaging and supermarkets | Letters
The idea of increasing the use of aluminium and steel packaging, as proposed by Andy Clarke (Bring in plastic packaging ban, former Asda boss tells stores, 13 October), is not a sustainable solution. Both materials rely on finite substances and intensive energy to produce them, and there is no guarantee that they will be recycled and will avoid ending up in the sea as well. One possibility would be to increase the use of starch based “plastic”; it’s biodegradable and therefore matters less where it ends up. Obviously another solution is to avoid shopping in supermarkets as far as is possible and to instead shop in markets and smaller shops, which are less packaging obsessed and often use paper bags, as in the good old days.

Pipeline company downplaying major legal and financial risks of crossing unceded First Nations territory in British Columbia
The controversial expansion of a pipeline that would carry tar sands crude from Alberta to British Columbia’s coast will be doomed by the rising power of Indigenous land rights.
That’s the message that Kanahus Manuel, an Indigenous activist from the Secwepemc Nation in central BC, plans to deliver to banks financing the project as she travels through Europe this week.

Scientists investigating marine life in the Baltic Sea have found mussels, oysters and clams are emitting greenhouse gases – but cows still trump them
Swedish scientists have found that flatulent shellfish are creating vast amounts of greenhouse gases, leading to a predictable slew of comments about farting cockles and clams. But beneath the schoolboy humour, there is a serious point. The two gases in question – methane and nitrous oxide – are potent agents of climate change, with a warming potential 28 and 265 times greater than carbon dioxide respectively.
Scientists studying the Baltic Sea off the coast of Sweden have found that shellfish are producing one-tenth of all the greenhouses gases released there – the equivalent to the amount produced by 20,000 cattle. If the same situation is being replicated around the rest of the world’s seas and oceans, we have a serious problem.

The war on coal is over. Coal lost | Dana Nuccitelli
Coal can’t compete with cheaper clean energy. The Trump administration can’t save expensive, dirty energy.
Last week, Trump’s EPA administrator Scott Pruitt announced, “the war on coal is over.” If there ever was a war on coal, the coal industry has lost. According to a new report from the Union of Concerned Scientists, many old American coal power plants are being retired or converted to natural gas, and new coal power plants aren’t being built because they’ve become more expensive than natural gas, wind, and solar energy:
The share of US electricity coming from coal fell from 51 percent in 2008 to 31 percent in 2016—an unprecedented change. New UCS analysis finds that, of the coal units that remain, roughly one in four plans to retire or convert to natural gas; another 17 percent are uneconomic and could face retirement soon.

Raw sewage 'flowing into rivers across England and Wales'
WWF analysis reports that 40% of rivers are polluted with sewage that can harm wildlife and put human health at risk
Raw sewage is flowing into rivers at thousands of sites across England and Wales, a report has warned, harming wildlife and putting human health at risk.
The total amount of raw sewage intentionally being put into rivers is unknown, which is a “huge concern”, according to conservation group WWF, which produced the analysis. The available data suggests that more than half of overflow sites spill sewage into rivers at least once a month and 14% at least once a week.

Our cities need fewer cars, not cleaner cars
Electric cars won’t eradicate gridlocks and air pollution, but carbon footprints could be cut by favouring pedestrians, cyclists and mass transit
The spectre of our cities choking with unhealthy air has prompted numerous governments to mandate a transition to electric cars. Their concerns are well founded, even if their proposals fall short of what is needed.
Over the past four decades, cars have become far less polluting. Their fuel efficiency has practically doubled and their tailpipe emissions have been reduced by more than 95%. Yet cities such as London and Paris are still battling smog and pollution. California has for decades demanded the toughest emission standards in the US, and yet Los Angeles heads the list of US cities for bad air quality. Moving to all-electric car fleets will be a positive step, albeit an inadequate measure.
