It was Koichi Takahashi's dream to create a sustainable society through recycling and regeneration. His dream came true when he built a company that turns food waste into high-quality pig feed. In his company, Japan Food Ecology Center, Takahashi made use of the popular Japanese practice, "fermentation".
Food experts predict that food trends will be shaped by a desire for authenticity, environmental protection, and exciting flavors. They also believe that global flavors will be a big trend, with chefs creating dishes that reflect their diverse backgrounds. Asian ingredients, like black sesame and ube, will become more popular as people will start to appreciate the unique qualities of different Asian cuisines.
In 1939, the typical Japanese person only ate 4 grams of meat per day. Today, the average person eats 130 grams, and their favourite meat is pork, not fish as one might expect. One of the reasons for this significant change was the rise of Western influence in Japan.

The Amsterdam company Respyre has developed concrete and plaster that support the growth of moss. These materials can be used for new construction, as well as on existing buildings. The moss then acts as a respiration system for the city. It takes in water and CO2 from the air and releases oxygen.
Moss has other benefits, too. Watch this short video to find out more.
The standard measure of economic performance, the gross domestic product (GDP), measures the value of goods and services produced within a country over a given period. However, the GDP doesn’t measure social factors like income inequality, domestic violence, drug addiction, or the impact of today’s actions on future generations. It also ignores sustainability and environmental destruction. It’s a very short-term view of market factors without respect to what’s happening on the social and environmental levels.
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.
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:
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.
According to PhysOrg, a scientific publication, scientific knowledge used in international studies is predominantly sourced from English-language documents, as it is assumed that all scientific knowledge is available in English. However, according to research scrutinizing over 400,000 peer-reviewed papers in 326 journals, published in 16 languages, scientific papers written in languages other than English may hold untapped information crucial to the conservation of global biodiversity.
For $200, you can now invest in the eco-fashion label Christy Dawn. The label is selling "plots" in the organic, sustainable cotton farm in India that provides the raw materials for their clothing. At the end of the season, you're paid back with store credit. If the harvest is good, you might get back more than the initial $200 you invested. On the other hand, if it's a bad year for cotton, you could lose most or all of your money.
Algae is used in lots of ways, from food to health supplements to fuel. Now we can add flip-flops to the list. Flip-flops, commonly made from rubber, foam or plastic, are hugely popular all over the world. When people lose theirs on the beach, which happens frequently, the flip-flops are swept into the ocean to join the rest of the plastic pollutants collecting there.
Electronic waste is a huge problem. There's an estimated 51,000 tonnes of it globally per year, says the European Union. But a new law could put an end to one part of it.
The E.U. has passed a law that as of 2024, all phones will have a standard USB-C charger. Having a single type of smartphone charging port will make cables interchangeable and more reusable. This standard charger would also improve the customer experience.
The 2019 Nobel Prize in chemistry has been awarded to three scientists who played a large role in developing lithium-ion batteries: Stanley Whittingham of the U.K., American John Goodenough (at 97, the oldest Nobel laureate ever), and Japan’s Akira Yoshino. Whittingham created the first functional lithium-ion battery in the 1970s, then Goodenough increased its capacity two-fold over the next 10 years. Finally, Yoshino removed the pure lithium, making it much safer to use.
The Rights of Nature is a global movement that views nature not as something that we own, but as something that has rights. There are many important parts of this movement, but one of the most important is water. It is said that water is likely to be the most pressing environmental concern of the next century.
