Chopsticks become furniture

People throw away more than 80 billion pairs of chopsticks every year. Most of them have only been used once, like the cheap wooden ones you get in restaurants. All of those chopsticks end up in landfills. In China, environmental activists have documented rates of over 100 acres of deforestation every day to keep up with demand.

One start-up has decided to tackle this problem by using discarded chopsticks as a construction material. ChopValue, based in Vancouver, Canada, collects about 350,000 used chopstics every week, just from the Vancouver area. They then use the chopsticks to make things for the home and office, like bookshelves, cutting boards, coasters, and even desks. Founder Felix Böck explains,

Why is English the global language?

English is a modern lingua franca. It is a leading language in so many areas: from global affairs and science to entertainment. One of the reasons for that lies in the colonial history of the British Crown in the 17th century, when the British Empire became the biggest empire in history. With colonialism, trade relations boomed, following the progress in science, industrial manufacturing and literature. However, there were many other competing languages, such as French, Spanish and German. To know more about how English won the competition against other languages to become a global communication tool, watch this short part of the video, "Why Did English Become the International Language?

Visuals: Fruit & Veggie consumption

People’s diets have varied considerably around the world, and have often been dictated by geography, the types of crops that the land can sustain and animals that dominate the ecosystem. However, with advances in technology and globalization, billions of people can now eat all sorts of fruits and vegetables out of season, as well as exotic, imported meats.

Take a look at the two maps below and discuss what you see with your teacher.

New Zealand new trade agreements

The UK agreement

A new free trade agreement with the UK allows New Zealand to remove export tariffs during the next 15 years. This deal promises a GDP boost of up to $1 billion.

On top of the economic elements, the agreement includes conditions for the environment, tackling climate change and creating equity in economic advancement. According to New Zealand Prime Minister, Jacinda Ardern, it is the country’s “first bilateral trade agreement to include a specific article on climate change”. 

Another unique point of that agreement is a separate Māori trade chapter featuring the acknowledgement of the relationships between the Māori people and the British, who colonised the country. In addition, the chapter included the protection of Ka Mate haka, in which the UK promises to protect the famous ceremonial dance. 

Floating solar farms

Floating solar farms, also known as "floatovoltaics," are an efficient way to collect solar energy. They have a number of advantages over land-based systems:

  1. They don't occupy land that could be used for other things, like crop farming.
  2. They're up to 16% more efficient because the water keeps them cool.
  3. They reduce evaporation on hydroelectric dams, saving more water for hydropower.

But they also come with an environmental cost: the panels sit on plastic floats. So far, floatovoltaic developers have relied on virgin (new) plastic to keep the panels afloat. As we know, plastic is one of the biggest contributors to pollution, uses fossil fuels to manufacture, and is deadly for sea creatures. But a new floatovoltaic farm in Alqueva, Portugal, is under development by the EDP corporation, an energy company committed to sustainability. 

Leadership and work-life balance

According to the Harvard Business Review (HBR), it is possible to be a business leader and still have a personal life with careful planning, but most people wouldn’t know this if they look at some of the most successful CEOs out there. Tesla CEO Elon Musk rarely sleeps or sees his kids and had a public meltdown, and Apple’s Tim Cook is on email before the sun rises.

These intense work styles are often celebrated as the only way to get to the top and be a super-productive leader. Surveys show that managers and executives describe the ideal worker as someone with no personal life or caregiving responsibilities.

Visuals: Racism in football

European football (soccer) has a history of racism. Recently, there has been a rise in racist comments from fans against players of color. Many football clubs are taking action against it. There are even projects involving computer- and A.I.-assisted technology to pinpoint racist fans.

But fans aren't just shouting abuse at matches; they're using social media as well. A 2021 study of online messages against the U.K's Premier League players found more than 3,000 abusive messages, 56% of which were racist.

So, how are social media platforms responding? Are they doing enough? The graph below shows what fans across Europe think.

Modern humans hold ancient DNA

For a long time, we believed that Neanderthals and Homo Sapiens (modern humans) were two separate species. With the advent of DNA sequencing, however, it was discovered that Sapiens interbred with Neanderthals as they migrated from Africa 60,000 years ago. Another previously unknown hominid species, known as Denisovans, was also discovered at that time, and it interbred with Sapiens and Neanderthals, too.

Gene sequencing shows that non-African genomes today contain about 2% Neanderthal DNA, and people from Papua, New Guinea, and Australia are about 3% Denisovan. Studies on modern African DNA are taking longer because climate, geography and politics make locating skeletons much more difficult.

Visuals: the price of war

The war in Ukraine has had a vast impact on the whole world. In addition to the humanitarian catastrophe, it has also caused increased rates of inflation all over the globe. 

This rise is mostly linked to increases in food, energy prices and disrupted supply chains. The impact is affecting the poorest countries the most. 

Look at the graph below describing the projected inflation rates for several countries, and discuss it with your teacher.

The Taliban asks for help

A deadly 6.1-magnitude earthquake hit Afghanistan on June 22. So far, more than 1000 people have been reported dead, and at least another 1500 have been injured. This is a humanitarian disaster that requires aid.

People in remote areas have to dig through the rubble with their bare hands, hoping to find people under the destroyed buildings. In addition, recent rains have damaged many roads making access even more difficult. Afghanistan has already experienced multiple humanitarian crises in recent months. This has caused shortages. 95% of households do not have enough food and the health system is not functioning properly.

Elon Musk bans remote work

Elon Musk has ordered all employees to return to the office full-time or resign. In two leaked memos, he makes it clear that remote work will not be allowed except for "particularly exceptional contributors for whom this is impossible". These memos have been reported on news networks and Twitter feeds. The news network CNBC transcribed the first memo.

How Meta targets political ads

Meta, owner of Facebook and Instagram, says it will provide outside researchers more information on how political and social ads are targeted on its platform, providing insight into the ways that politicians, campaign operatives and political strategists buy and use ads during election periods. Starting from May 2022, academics and researchers registered with Facebook Open Research and Transparency will be allowed to see more detailed targeting data, including which interest categories—such as “people who like dogs” or “people who enjoy the outdoors”—have been chosen to aim ads at specific people.

Meta also plans to include summaries of targeting information for some of its ads in its publicly viewable Ad Library. Created in 2019, the Ad Library allows the public to obtain information about political ads, thus helping to safeguard elections against the misuse of digital advertising.

Breakthrough in medicine

New research from the Babraham Institute has potentially made a revolutionary breakthrough in regenerative medicine. The scientists developed a method to rejuvenate skin cells by 30 years. 

Our cells have several functions, such as providing structure and support, transporting molecules, producing energy, helping with growth, creating metabolic reactions and helping in reproduction. However, with age, cells lose these functions and accumulate age marks. 

New research reprogrammed cells by restoring their functions and changing the molecular measures of biological age. Rejuvenated skin cells produced more collagen that helped heal wounds and provide structure to our skin, the same as natural young skin cells do. 

This research is based on the Nobel Prize method developed by Shinya Yamanaka in 2007 of creating stem cells—cells that have the ability to turn into any cell type with any function. 

Nonprofit business: Clean the World

One night at a hotel in 2009, tech executive Shawn Seipler thought about how many bars of soap guests use for a night and then leave. He called the front desk to find out what they did with the used soap and learned that they just throw it away. In the U.S. alone, hotels throw out about 3.3 million bars of soap every day.

So, Seipler started Clean the World, a nonprofit that recycles soap, in his garage. He quickly discovered that major hotel chains, airlines, cruise companies and casinos were happy to pay him to take their waste. The business has since grown into a $750k production facility in Orlando, Florida, with branch operations around the world.

Do trees talk to each other?

People generally think of trees as disconnected loners, competing for water, nutrients, and sunlight, with winners shading out losers and sucking them dry. But evidence to the contrary is coming to light. Forest trees are, in fact, cooperative and live in interdependent relationships maintained by communication and collective intelligence similar to an insect colony.

Unlike other organisms, most of the communication between trees happens underground, through a system known as the “Wood Wide Web”. “[Trees] in every forest that is not too damaged”, explains Peter Wohlleben, a German forester and author, “are connected to each other through underground fungal networks. Trees share water and nutrients through the networks, and also use them to communicate. They send distress signals about drought and disease, for example, or insect attacks, and other trees alter their behaviour when they receive these messages.”

Indonesia bans palm oil exports

In late April, the Indonesian government announced a temporary ban on exports of crude palm oil and its refined products, such as cooking oil. The decision came as a surprise to commercial goods traders as the government had previously stated the ban would only apply to refined products. After the government’s initial statement, prices of crude palm oil significantly fluctuated given uncertainties about what products the ban would cover. Prices have again skyrocketed in light of the most recent announcement.

Since the beginning of the war in Ukraine, the world has seen a wave of food protectionism, as governments seek to protect domestic food supplies in light of surging agricultural prices. As the world’s largest edible oils shipper, providing one third of global supplies, Indonesia threatens to worsen global food inflation with its decision and raises the risk of a full-blown hunger crisis.

Health is a sustainability issue

Rare and neglected diseases remain a serious problem in our modern world, despite advances in science and technology. Big pharmaceutical companies don't fund research and development into treatments for these diseases because they aren't profitable. The drugs end up costing much more to make than they'll earn back, so they remain un- or underfunded.

Each rare disease affects relatively few people, so the market is too small to make a profit on treatments. Neglected diseases affect about 1 billion people, but most are in underdeveloped, tropical countries. So, although the market is big, treatments are a poor return on investment because the countries can't afford to pay for them.
