In the last few years, biotechnology has been changing the way we think about fashion by turning organic waste into sustainable fibers. Revolutionary textiles (纺织品) made from pineapples, oranges，grapes, and even mushrooms are here to stay. And now, an amazing invention joins the sustainable trend by turning spoiled milk into biodegradable (可生物分解的) T-shirt.

Mi Terro, an exciting and innovative startup based in Los Angeles, was founded by CEO Robert Luo. After visiting his uncle’s dairy farm in 2020, and noticing the huge amounts of milk being dumped, Luo realized something must be done. According to Mi Terro, 40 percent of food including 128 million tons of milk is wasted annually. This generated around 3.3 billion tons of greenhouse gases.

Luo soon came up with a way to turn food waste into clothes, turning the spoiled milk into biodegradable fibers to form an eco-friendly textile.

Not only is Luo’s solution extremely creative, it also adds benefit to the clothing he manufactures. According to Interesting Engineering, the process uses 60 percent less water than is used when making organic cotton shirts and the textile feels three times softer than cotton. Plus, the clothing is antibacterial, anti-wrinkle, and temperature regulating. These clothes are also healthy to wear; each T-shirt has 18 amino acids (氨基酸) that benefit the skin. But there’s even more! The company has committed to planning 1S trees for every purchase.

Mi Terro launched its milk-made T-shirts-online in 2021, and they now sold in over 40 countries around the world. Its groundbreaking process can also be used to create a sustainable substitute for plastic. Their ultimate goal would be to replace petroleum-based materials with protein-based materials made from food waste. This, in itself, has countless applications for the fashion, health care, and packaging industries.

Innovative and inspiring solution are proving to be the answer to growing waste and sustainability challenges the globe faces these days. Eco-conscious businesses like Mi Terro are creating a circular economy and are having a huge positive impact on the environment. Their vision for sustainable solutions may soon impact the entire world.

Global animal populations are declining, and we’ve got limited time to try to fix it. That’s the outcome of a new report from the World Wildlife Fund (WWF), which analyzed years of data on wildlife populations across the world and found a downward trend in the Earth’s biodiversity.

According to the Living Planet Index, animal populations across the world decreased by 69% between 1970 and 2018. Not all animal populations decreased, though, and some parts of the world saw more dramatic changes than others. But experts say the loss of biodiversity is a worrying sign of what’s to come for the natural world. “The message is clear and the lights are flashing red,” said WWF International Director General Marco Lambertini.

According to the report’s authors, biodiversity loss mainly results from land-use changes driven by human activities, such as infrastructure (基础设施) development, energy production and deforestation. But the report suggests that climate change — which is already causing wide-ranging effects on plant and animal species globally — could become the leading cause of biodiversity loss if rising temperatures can’t be limited to 1.5℃.

Lambertini said the crisis of biodiversity loss and climate change is already responsible for plenty of problems for humans, including less access to food and water and a rise in the spread of diseases. He said world leaders should take major steps to deal with environmental damage. They are locked in old-world thinking, with no sign of the brave action needed to achieve a nature-positive future.

WWF chief scientist Rebecca Shaw told a radio station that humans have the opportunity to change how they do things to benefit nature. “We don’t have to continue the patterns of development we have now. And we have an opportunity to change the way we produce, what we cat and how we consume food and what we waste when we consume our food,” Shaw said. “Little things that we can do every day can change the direction of animal population declines.”

The world celebrates Earth Day every year on April 22.But one school in Potomac，Maryland tries to honor Earth Day every day.Very young children are learning about the environment and taking action to show their love for the Earth.

A child’s world is the world of playing.They love being outside in the open air，running，sliding and swinging on playground equipment.But children at St.James Children’s School also add to that fun by picking up rubbish in the school.Inside，they learn to save water and electricity.They also recycle and reuse things.And every spring they get the soil ready to plant flowers and vegetables in the school garden.

The children at St.James range from six weeks to six years old.The environmental study begins at age two.Rebecca Boker teaches the children the importance of taking care of the Earth.Boker says every day at St.James is Earth Day.She points to books in all the classrooms and in the library.Most contain materials that urge children to do something to help the environment and protect the Earth.

St.James children observe the growth of plants from seeds to sprouts(苗，芽) in cups kept in the classroom.Then they watch the plants continue to grow after placing them in the garden.The students also observe the lifecycle of some insects.After that，they know it is their job to respect their home just like they want others to respect theirs.

But do these very young children really get the message that their teachers try to communicate？Ms Boker says yes.On April 22 the kids at St.James will go out to the school’s garden for the yearly clean­up.But for them，Earth Day will continue for the school days ahead as well.
