Microplastic quantities on the seafloor triple in 20 years
The team from the Autonomous University of Barcelona (AUB) and Aalborg University said the increase corresponds with the type and volume of consumption of plastic products by society over that time.

The study is the first high-resolution reconstruction of microplastic pollution from sediments obtained in the north-western Mediterranean Sea.

Despite the seafloor generally being the final sink for microplastics floating on the sea surface, the level of build-up and the sequestration and burial rate of smaller microplastics on the ocean floor is unknown.

It was found that microplastics are retained unaltered in marine sediments, and that the microplastic mass in the seafloor mimics the global plastic production from 1965 to 2016.

“Specifically, the results show that, since 2000, the amount of plastic particles deposited on the seafloor has tripled and that, far from decreasing, the accumulation has not stopped growing mimicking the production and global use of these materials,” said AUB researcher Laura Simon-Sánchez.

The sediments analysed were found to have remained unaltered on the seafloor since they were deposited decades ago.

“This has allowed us to see how, since the 1980s, but especially in the past two decades, the accumulation of polyethylene and polypropylene particles from packaging, bottles and food films has increased, as well as polyester from synthetic fibres in clothing fabrics,” explained AUB researcher Michael Grelaud.

The team found roughly 1.5mg of these three types of plastic per kilogram of sediment collected, with polypropylene being the most abundant, followed by polyethylene and polyester.

Rishi Sunak has reversed his decision to skip the Cop27 climate summit in Egypt next week, bowing to pressure from activists, his own environment adviser and Boris Johnson.
The Prime Minister accepted there is “no long-term prosperity without action on climate change” as he confirmed he will attend the UN talks in Sharm El Sheikh that start on Sunday.

Mr Sunak had been declining to go, arguing that he needed to focus on the “depressing domestic challenges” as he worked on the autumn Budget with Chancellor Jeremy Hunt.

Downing Street said he changed his mind after making “good progress” ahead of the financial statement, but Labour accused the Prime Minister of having been “dragged kicking and screaming into doing the right thing”.

Cop26 president Alok Sharma, who will be handing over the UK’s presidency to Egypt at the summit, said he is “delighted” about the U-turn, having previously expressed his disappointment.

Lord Deben, the chairman of the UK’s independent Climate Change Committee, also said he is “pleased” Mr Sunak will be attending the summit.

But he warned the UK’s delivery on climate change has been “appalling”.

Mr Sunak announced his attendance the morning after Mr Johnson, one of his predecessors in No 10 and an enduring rival in the Conservative Party, confirmed he will be joining the talks in Egypt.

“There is no long-term prosperity without action on climate change,” Mr Sunak tweeted.

“There is no energy security without investing in renewables.

“That is why I will attend @COP27P next week: to deliver on Glasgow’s legacy of building a secure and sustainable future.”

• Bitcoin vs. Ethereum
• Will Bitcoin Continue Its Dominance

The war of narrative between Ethereum and Bitcoin is nothing new. However, Dennis Porter, the CEO of Satoshi Act Fund, has a chilling warning for the Ethereum community. Porter believes that this is Ethereum’s last cycle as the second largest cryptocurrency.

 

Porter is an advocate for the Bitcoin ecosystem and the Proof-of-work consensus mechanism. He is also a vital contributor to Bitcoin policy advocacy. 

Porter claims that Vitalik Buterin had years to prove Ethereum’s usability. However, the Ethereum founder failed to provide any reasonable value for Ethereum. He believes that multiple blockchains can contribute similarly to Ethereum. On the other hand, Bitcoin does not have any competitor as a store of value. 

Bitcoin vs. Ethereum

The long-standing battle between Bitcoin and Ethereum continues to exist. However, after the merge, this battle exacerbated even more. The merge shifted Ethereum’s consensus mechanism from Proof-of-work to Proof-of-stake. Ethereum proponents claim that the PoW’s energy consumption makes it unsustainable. 

Indeed, many activists claim that the Proof-of-work consensus mechanism should be banned on account of its energy consumption. 

On the other hand, the Bitcoin community claims that the Proof-of-stake has potential issues with centralization. Indeed, after the merge, Lido and Coinbase, the two biggest validators, performed a majority of block validation. Moreover, Bitcoin maximalists claim that Ethereum has a negative reward structure which will create issues in the long term.
