2 . Are you a tea drinker? If so, you’re not alone. Every day around the world millions of cups of this popular brew are drunk, and it’s been that way for thousands of years. The oldest discovered tea is from the Han Dynasty, dating from 206BC to 220AD. But it’s thought that the tea trend really took off during the Tang Dynasty in the 8th Century, when it became China’s national drink. Now, Turkey, the Republic of Ireland and the UK are believed to be the biggest tea—drinking nations, per capita.
Tea is consumed in many ways-slurped, sipped or glugged. It can be poured from pots, infused or brewed in the cup using tea bags—and it’s this latter process that is causing concern. Research last year found some premium tea bags might be leaving billions of microscopic plastic particles in the cup. Scientists from McGill University in Montreal found that some ‘plastic’ tea bags shed high levels of micro plastics into water. However, The World Health Organization says such particles in drinking water do not appear to pose a risk.
Most tea bags are made from paper, with a small amount of plastic used to seal them shut— made from oil. This has led to debate about whether they can be recycled, but many are still composted. However, gardener Mike Armitage has told the BBC that the plastic contained in the soil could be washed into streams and rivers and ultimately out to sea.
Unilever, the owners of the tea brand PG Tips, said their tea bags are made with a small amount of plastic—used to seal them—and that they are suitable for composting. And the brand Yorkshire Tea said their bags do contain 25% polypropylene, but they were “actively developing plant—based and biodegradable alternatives”.
While tea bag manufacturers might be doing their bit to reduce plastic pollution, it could be a good time to switch your favourite beverage to coffee, or if that isn’t your cup of tea then try using loose-leaf tea, which can have a better flavour.

3 . Two thirds of the ice in the glaciers (冰川) of the Alps is doomed! These glaciers will melt by the end of the century as global temperatures rise, according to a recent study.
Scientists claim that half the ice held in some 4,000 Alpine glaciers will disappear by 2050 due to global warming through the effect of past emissions. After that, even if carbon emissions drop to zero, two-thirds of the ice will still have melted by 2100. If emissions continue to rise at the current rate, the ice tongues will have all but disappeared from Alpine valleys by the end of the century. The most pessimistic prediction tells us that the Alps will be mostly ice-free by 2100. Only isolated ice patches would remain at high altitudes, representing five per cent, at most, of the ice volume seen today.
The researchers warn that the loss of these glaciers will mean much less water is available for farming and hydroelectricity, especially during droughts. It would also affect nature and tourism.
In February, a study found that a third of the huge ice fields in Asia’s towering mountain chains were also under threat for the same reasons. This will lead to serious consequences for almost two billion people who live downstream. Glaciers along the Hindu Kush and Himalayan range are at higher, colder altitudes. If global carbon emissions are not cut, however, two-thirds of their ice could be gone by 2100.
The latest research combined computer models with real-world data to forecast the fate of the glaciers. It used 2017 as its starting point. Unlike previous work, these models included how the glaciers move down the mountains. Applying this approach to other glaciated mountain chains could improve ice loss forecasts there.
Cutting the emissions from fossil-fuel burning, deforestation and other polluting activities is the biggest factor in minimizing the melting of the ice. The future of these glaciers is indeed at risk, but there is still a possibility of limiting their disappearance.

4 . Sprite has been recognized for decades by its green cans and bottles, but it is retiring its green plastic bottles after more than 60 years.
Starting Aug. 1, the Coca-Cola Co., which produces Sprite, will package the lemon-lime drink in clear plastic bottles in North America, the company announced Wednesday. Sprite’s current plastic contains green polyethylene terephthalate(PET)(聚对苯二甲酸乙二醇酯), an additive(添加剂) that can’t be recycled into new bottles, a key choice for the company as it looks to reduce plastic waste.
“When recycled, clear PET Sprite bottles can be remade into bottles, helping drive a circular economy for plastic.” Julian Ochoa, CEO of R3CYCLE, a plastic group helping Coca-Cola improve its recycling, said in a statement.
Customers will also notice a revised logo and packaging design on the Sprite bottles that aims to provide a more “consistent look around the world,” the company said. The well-known green color will still be used on Sprite labels. Other beverages that use green bottles in Coke’s portfolio(系列产品), including Fresca. Seagram’s and Mello Yello, will also be replaced with clear containers in the coming months.
Coca-Cola reported higher-than-expected second-quarter earnings Tuesday, citing strong demand, and lifted its revenue forecast for the full year.
The beverage giant has often been criticized for contributing to environmentally damaging plastic waste. In 2020, the company was named as the world’s No. 1 plastic polluter by the environmental firm Break Free From Plastic. Its logos and branding were found on 13, 834 pieces of discarded plastic in 51 countries, often in public spaces such as parks and beaches.

6 . There is a kind of climate pollution that we can’t see clearly. It isn’t in our rivers, lands or skies, it is in our minds. When climate disinformation goes unchecked, it spreads like wildfire, undermining the existence of climate change and the need for urgent action.
Like the biosphere that sustains us, the health of our information ecosystems is vital to our survival. As an artist, I feel a responsibility to create new ways of seeing the disinformation that has come to define the age of fake news.
Social media sites are honed to grab our attention. Using sophisticated algorithms, the corporations behind them decide what billions of people see around the world, dictated by what keeps you hooked, but also by what the companies paying social media sites choose to put in front of you.
Powerful corporate actors deploy clever influence campaigns via ads targeted at specific users based on what social media firms know about those people. Major oil and gas companies have spent billions of dollars over the years persuading consumers about their green proofs, when only 1 per cent of their expenditure in 2019 was on renewable energy. This is known as corporate greenwashing. Still, fossil fuel firms maintain that their climate policies are “responsible” and “in line with the science”.
To expose the scale of corporate greenwashing online, I was part of a team that recently launched Eco-Bot.Net. Co-created with artist Rob “3D” Del Naja of the band Massive Attack and Dale Vince, a green entrepreneur, Eco-Bot. Net’s AI-powered website ran throughout the COP26 climate summit, exposing climate change misinformation by releasing a series of data drops for heavily polluting sectors, including energy, agribusiness and aviation.
Academic definitions of climate disinformation and greenwashing were used to unearth posts across Facebook, Instagram and Twitter and visualize them on our website. Eco-Bot.Net then flagged greenwashing ads and posts on the original social media site with a public health warning.
By digging into our data, journalists have already revealed that companies are targeting specific demographics in order to influence public perceptions about climate change – and even alter government policy.
One data drop focused on the 100 biggest fossil fuel producers, companies that have been the source of 71 per cent of global carbon emissions. It found that 16 of these companies ran 1705 greenwashing and climate misinformation ads globally on Facebook and Instagram this year. In total, they spent more than £4 million creating influence campaigns that generated up to 155 million impressions.
Social media companies could end most of the harms from climate disinformation on their platforms if they wanted to. Flagging systems were swiftly introduced to warn users of posts containing disinformation about covid-19. The scientific consensus on human-caused global warming has been resolute for decades, so why can’t a similar flagging system be implemented for related disinformation?
It is true that Twitter and Facebook have both introduced climate science information hubs, but these are little more than PR exercises that fail to directly tackle climate disinformation on any kind of scale.
This epidemic of climate change disinformation on social media is eroding collective ideas of truth. In this post-truth age of disinformation, we hope that the public, the press and policy-makers will be able to use our data findings to see what is hidden by what we see online.
For the first time, we can witness the regional scale of corporate greenwashing. The era of climate denial and delay is largely over — except, as Eco-Bot.Net has revealed, on social media.

8 . From the Hanging Gardens of Babylon to the orange gardens of Seville, urban planners down the ages have taken inspiration from nature.

9 . More than 45,000 years ago, by the shore of present-day Tasmania, a local person picked up a large piece of thick, dark brown seaweed. And he realized that this giant piece of seaweed could be used to make a watertight(不透水的) bag. And 45,000 years later on mainland Australia, people are again turning to seaweed to solve pressing problems. Today, it is used to address the world’s climate crisis.
Winberg, a marine ecologist, has spent decades studying seaweed. She believes seaweed’s fast growth rate and ability to absorb vast amounts of carbon dioxide can help fight climate change, clean the oceans, and change the way we farm, not just in the oceans but also on land.
Realizing seaweed’s potential as a climate solution, Winberg opened Australia’s first land-based, commercial seaweed farm in 2013. On her farm Winberg produces seaweed juices that are used in food, and medicines. Like plants on land, seaweed absorbs CO2 and grows biomass(生物量). Coastal marine systems can absorb carbon at rates up to 50 times greater than forests on land. Globally, seaweeds are thought to sequester nearly 200 million tons of CO2 every year — as much as New York States annual emissions. And when the seaweed dies, much of the carbon locked up in its tissues is transported to deep oceans.
The potential for seaweed doesn’t stop in the oceans. Winberg has found there are benefits on land, too. She believes that seaweed farming offers “huge potential” to not only address the climate crisis, but also feed a growing population in a sustainable way. According to Winberg, one hectare of a seaweed farm can produce more protein than the same amount of land used for cattle. “We’re sitting on undiscovered, renewable, sustainable resources,” she says.
In the thousands of years of human experimentation with seaweed, the scale of the challenges that seaweed can help solve has grown largely. But some things are still the same. To the Aboriginal Australians living in Tasmania who first discovered some of seaweed’s uses, it might have seemed like a wonder material as they made watertight bags out of it. To seaweed experts like Winberg today, this old idea is still ringing true.

10 . Roads and railways have made it easy for people to travel around the UK, but have had the precisely opposite effect for insects. Alongside housing developments, transport infrastructure (基础设施) has separated insect habitats, leaving many pollinators (传粉昆虫) stuck on decreasing islands of biodiversity.
A new conservation project aims to address that by creating a network of wildflower superhighways across the UK. The B-Lines network aims to join the dots between meadow habitats, enabling pollinators and other wildlife to move freely between them. Ten years in the making, the B-Lines initiative was launched by the insect charity Buglife on Tuesday and has already generated interest from unexpected quarters. “After the launch, some house builders rang up asking how they could include the network into house building, so it could have a really positive effect,” said Buglife’s Paul Hetherington.
Buglife has spent the last decade mapping potential routes for the insect superhighway. Hetherington said the proposed highway could give the UK’s weak insects a boost and a route out of habitats that become too hot due to the climate crisis and it can make a huge difference in easing declines. “The things that have really hammered pollinators are habitat loss, loss of connectivity of habitat, climate change and pesticides—this deals with everything except pesticides,” said Hetherington.
The B-lines network is not just a concept. Pilot sections have already been completed, including the South Wales B-Lines near Cardiff. “Since that was done, there have been recordings of one of our rarest bees in Cardiff town centre, which shows this connectivity can work,” said Hetherington. And in Norwich, Buglife has been working with Network Rail to plant wildflowers along the track. Anyone living along the proposed route can get involved in the project. All they need to do is let their lawns grow, or even just create a small herb garden, which Hetherington likened to creating a “motorway service station for bees”.
