IN PICTURES: German climate activists pull ‘oil stunt’ at Chancellery

The war in Ukraine and its economic fallout has dominated the news agenda in Germany for months. In a bid to get climate change back on centre stage protestors have had to be bold.

With climate change pushed down the news agenda as Germany tackles an energy crisis and the war in Ukraine, environmental activists are resorting to increasingly eye-catching stunts to get their message across.

This week, around a dozen activists sprayed a black liquid that looked like oil on the chancellery in Berlin and stood in front of the building with a banner that read: “Save oil instead of drilling.”

Dressed in orange high-visibility jackets and hard hats, the protesters were members of Letzte Generation (“Last Generation”) — a radical protest group that has become the new face of environmental activism in Germany.

“The government has ignored everything else: petitions have been written, a million people have taken to the streets,” said Lina Joansen, a 24-year-old student taking part in the protest.

The activists want a promise from the government that it will not drill for oil in the North Sea.

“We know that fossil fuels can only aggravate the climate catastrophe that is already happening,” said law student Myriam Herrmann, 25.

Six months ago, a new coalition government was elected in Germany on a promise to make climate change one of its top priorities.

The Greens entered power for the first time in more than two decades, forming a coalition with the Social Democrats (SPD) under Chancellor Olaf Scholz and the liberal FDP.

Ambitious climate plans

Green party Economy Minister Robert Habeck announced an ambitious 60 billion euro ($68 billion) climate investment plan and promised that German would end coal power and generate 80 percent of electricity from renewables by 2030.

But since then, climate concerns have been overshadowed by the war in Ukraine, an acute energy crisis and record inflation.

Germany has accelerated plans to import liquefied natural gas (LNG) by sea, wants to explore new oil and gas reserves in the North Sea, and has even decided to reactivate mothballed coal-fired power plants.

The government has said it is still on target to meet its 2030 climate targets, but the protesters are not convinced.

Herrmann is “incredibly disappointed”, especially with Habeck. “We don’t have time for stopgap solutions any more,” she said.

Letzte Generation was born following a hunger strike last year by activists demanding a law to ban supermarkets from destroying unsold food products.

Earlier this year, small groups of Letzte Generation protesters blocked busy roads in Berlin by sitting down and glueing their hands to the tarmac.

More than 100 were arrested.

A few days after the oil protest, the group once again employed these tactics, with about 65 protesters blocking the Frankfurter Tor intersection in Berlin’s Friedrichshain.

‘Legitimate means’

Civil disobedience is “an established mode of protest in the German environmental movement”, sociologist Michael Neuber told AFP, recalling the anti-nuclear movement of the 1970s and blockades by the Extinction Rebellion in 2019.

Such protests have been overshadowed over the past two to three years by the massive student-led demonstrations of the Fridays for Future movement, but have more recently started to make a comeback.

“Civil disobedience attracts more attention than demonstrations,” said sociologist Dieter Rucht.

“I see civil disobedience as a legitimate means of political protest, when it is peaceful,” 27-year-old Green party politician Deborah Duering told RBB radio this week, claiming to share the “anxiety” of the activists.

In February, by contrast, many voices within the Green party had criticised Letzte Generation for blocking the roads in Berlin.

For Herrmann, if politicians want the protests to stop, there is an easy solution.

“It is enough for Scholz and Habeck to declare that they no longer want to encourage oil drilling in the North Sea,” she said.

Scientists warn poison contamination in the Baltic Sea could affect German fisheries

A team of researchers are sounding the alarm after confirming high levels of a toxic heavy metal in the Baltic Sea. Human activity, including proposed efforts to fix other environmental issues in the region could make the contamination worse.

Scientists warn poison contamination in the Baltic Sea could affect German fisheries

Scientists have warned that thallium levels in the Baltic Sea are significantly higher than previously thought.

A team of researchers from the American Woods Hole Oceanographic Institution (WHOI), confirmed that large parts of the Baltic Sea are already contaminated with the toxic heavy metal.

Their research, recently published in the Environmental Science & Technology journal, suggests that increased thallium levels in the Baltic Sea are a result of industrial activity in the region.

Thallium is considered the most toxic heavy metal for humans and animals. 

“Humans are releasing a lot of thallium into the Baltic Sea, and people should be made aware of that,” said Chadlin Ostrander, postdoctoral investigator in WHOI’s Department of Marine Chemistry and Geochemistry, in a summary of the research published by WHOI.

“If this continues…more thallium could accumulate. That would be of concern because of its toxicity,” he added.

Where does the thallium in the Baltic come from?

For now, thallium levels in Baltic seawater remain low. So you don’t need to cancel your trip to the Baltic Coast this summer.

That’s because most thallium in the Baltic is present in a layer of sulphide lying under the sand.

As long as thallium stays under the seabed in this form it remains harmless to marine life and humans, but construction work that disturbs the sea floor can release thallium isotopes into the water.

According to the research, between 20 and 60 percent of the toxic thallium that has entered the Baltic Sea in the last 80 years is due to human industry or shipping.

By analysing sediment core samples from the seafloor, the researchers determined that thallium enrichment picked up around the 1940s, suggesting its link to certain industrial activity.

“We predict, based on activities in the region, that the source of the thallium pollution is historic cement production in the region,” said senior scientist in WHOI’s Department of Marine Chemistry and Geochemistry, Colleen Hansel.

“As cement production continues to rise globally, this research could serve to caution manufacturers about the need to mitigate potential downstream effects of cement kiln dust on surrounding aquatic and marine ecosystems.”

Human impacts are creating a toxic sea

Sune Nielsen, co-author of the study and adjunct scientist in WHOI’s Department of Geology & Geophysics suggests that thallium contamination may not be the most immediate concern for the Baltic Sea ecosystem.

“As a Danish national, I follow the bad news about the Baltic in the Danish media, and our finding just adds another dimension to the already poor conditions in the basin for marine life,” Nielsen said.

An influx of farm-fertilisers and sewage-treatment discharge into the sea has resulted in the Baltic being home to seven of ten of the world’s largest known marine “dead zones”. These occur when excess algae and bacterial growth, fuelled by pollution, use up too much oxygen in the water causing fish and marine life to die off.

But human efforts to revitalise these dead zones could exacerbate thallium contamination, the researchers warn.

Current proposals to reoxygenate dead zones consist of pumping oxygen into the sea, which the researchers say would disturb sediment layers and mix thallium into the seawater where it could be absorbed by fish and enter the food chain.

“There is no doubt in my mind that it adds to the urgency of needing to do something to bring the Baltic Sea back to a state where humans and marine life can co-exist naturally,” said Nielsen.

To be clear, despite the Baltic Sea being one of the most polluted areas in the world, fish from the region are still safe to eat.

Randel Kreitsberg, a marine scientist at the University of Tartu in Estonia puts it this way in a university blog article: “The environment and the Baltic Sea are contaminated by tens of thousands of toxic substances, and even a person walking down the street is exposed to tens and hundreds of toxins…are fish from the Baltic Sea safe to eat? A short answer would be yes, they are.”

What is thallium?

Particularly toxic to mammals, thallium is a heavy metal which is not found freely in nature. 

It has previously been used in rat poisons and also as a lethal poison on people. For example, the Stasi used thallium to attempt to kill dissident Wolfgang Welsch in 1981 after he had successfully escaped East Germany.

A lethal dose of thallium for adults is around 800 milligrams, but it is easily absorbed by the body and hard to get rid of. So even small doses should be avoided.

Since 2006, the German Institute for Risk Assessment has advised that the daily intake of thallium should not exceed ten micrograms (millionth of a gram) per day. 

Commercially thallium is primarily used in the electronics industry, and to a lesser extent in the pharmaceutical and glass manufacturing industries.
