1 . More than one-third of the world’s food is wasted or thrown away, most of which ends up in landfills, producing very large amounts of planet-warming greenhouse gases. Now, many studies show that it is becoming harder to grow enough food to feed an increasing population due to climate change and soil degradation.

But one of the most promising and simplest solutions lies in the problem itself: this wasted food — if composted (堆肥) — could slow climate change and improve soil quality. Higher-quality soil also continues to absorb more carbon from the atmosphere, helping to improve plants and contributing further to fighting climate change. Returning one ton of organic matter to each hectare of soil would increase the production of cereal crops each year in Africa, Asia and South America by millions of tons.

While it is true that people can compost in their yards, community gardens, or even on their kitchen counters, larger-scale efforts, including infrastructure (基础设施) and incentives (激励) for consumers, would take it to the next level. Imagine if consumers could just leave unwanted food in a roadside bin for pickup, or drop it off at a local store, earning a few cents a bucket, just like what has been offered for recycling bottles or newspapers.

Moreover, in the case of composting, the payment incentive system would be sustainable because the end-product of compost can be sold to farmers, making it an economically workable model, something that is often lacking in recycling, especially for certain materials, like many types of plastics.

Eventually, more widespread composting of food would pave the way for solutions to additional waste challenges, such as the disposal of packaging and clothing. This will have other positive effects as well; if more consumers compost, companies will be more inspired to make and use compostable packaging, clothing, and other products. While more compostable items are starting to emerge today, additional composting will further drive demand and innovation, and offer a game-changing solution for the planet.

2 . In the midst of an already record-breaking heat wave, Phoenix, Arizona, set a particularly eye-popping record: the temperature only dropped to 97 degrees Fahrenheit overnight between Tuesday and Wednesday, setting an all-time record high for a nighttime low. When temperatures stay high overnight, they place a particularly heavy burden on the body, raising the risk of heat illness and death.

The U.S. —and the world—has seen a spate of extreme heat so far this year, including the planet’s hottest-ever June and hottest week on record during the first week of July. Rising global temperatures from burning fossil fuels are the main driver of more frequent and more intense heat waves. And an El Niño event is also boosting global temperatures this year.

A heat dome has been in place for weeks over the U.S. Southwest and Texas, and it has fueled many heat records. Phoenix has now seen 20 days in a row with a daytime high of 110 degrees F or higher, a record that is likely to continue for several more days. A heat dome is an area of high pressure that parks over a region. High-pressure ridges, as they are also called, feature sinking air, which compresses and heats up. These ridges’ typical clear skies also allow the sun’s rays to beat down on the ground, further raising temperatures.

Prolonged heat extremes pose a major public health threat because heat is the number-one weather-related killer in the U.S.; it causes more human deaths than hurricanes, tornadoes and floods combined. Heat can cause dehydration, which leads the blood to thicken and makes the heart pump harder. That organ and others can be damaged by too much exposure to heat.

The soaring, triple-digit high daily temperatures grab the headlines, and they definitely are a concern—but when temperatures only drop into the 80s and 90s at night, the body doesn’t get a chance to cool down. This is particularly a concern for those who lack air-conditioning, including unhoused populations. And heat is especially a health risk for the very young, the elderly and those with preexisting health conditions such as asthma and heart disease.

5 . Commercial aviation (航空) alone contributes around three percent of total global carbon emissions (排放). But the industry is actively looking for green solutions in the form of sustainable aviation fuel (SAF). In a study released this week, a team of researchers from the U. S. Department of Energy’s National Renewable Energy Laboratory (NREL) details a method of transforming food waste into SAF that can be used in existing engines. Making SAF is a more complicated process—it’s got to be very similar to the petrol-based aviation fuel we use today in commercial flights.

The researchers use volatile fatty acids (挥发性脂肪酸)(VFAs) from smelly food waste and transform it into simple paraffin molecules (石蜡分子) that can be used in fuel and really aren’t all that chemically different from traditional emissions-heavy fuels. There are other renewable biofuels that have been made from biomass (生物质), specifically oil and fat from vegetables and animals, but using the ever-mounting pile of food waste to fuel flights broadens those possibilities.

Derek Vardon, a senior research engineer at NREL, says major companies are eager to get involved in SAF because some sustainable solutions, such as battery-operated commercial flights, just aren’t possible yet with current battery technology. A battery-powered plane would be too heavy to fly long distances—“So using SAF that works in the same way as the fuel we have is a simpler way to trade out traditional emissions-heavy fuels.” Vardon also says that “because the wet waste would normally go to a landfill and break down to release greenhouse gases, the process of making and using SAF could actually have a negative carbon footprint when it is dramatically used.”

A major question as the researchers move forward with this type of research is if it is possible to run an airplane engine on fully renewable biofuel. Rolls-Royce recently did a test on one of their engines with 100 percent SAF and it worked. “This fuel is not crazy and we can solve these problems,” Vardon says.

7 . With the outbreak of the COVID-19, multiple kinds of protective medical equipment, such as disposable(一次性的)masks, have been consumed. Market research indicates a sharp increase rate of 53% in the mask market alone. People often use these types of protective equipment and then throw them without thinking of the consequences, both on the ecosystem and human beings.

Disposable surgical masks are severely affecting the ecosystem. When improperly-handled masks enter the water system, they break up into smaller pieces. Complete masks can trap marine animals, resulting in their impaired mobility and even death. Meanwhile, the poisonous plastic particles will cause marine animals to be poisoned to death or weakness when they consume plastic. Furthermore, these harmful pollutants can severely affect reproduction, growth, and the development of the young. Just like their effects on marine animals, these pollutants can also contribute to severe harm in human bodies, especially in the neuron system. Exposure to micro plastics may cause particle poisoning, cellular damage and neuro-degenerative (神经退化的) diseases like Alzheimer’s disease(阿尔茨海默症).

Despite the potential harm to the ocean system and human neuron system, improperly-handled disposable masks will likely become a dangerous public health threat under the environment of a global pandemic. Instead of helping us fight against the COVID-19, to some extent, micro plastic pollution also causes the potential risk of speeding up the spread of the virus. Micro plastic particles in the ocean can be mixed up with water vapour to form aerosols in the atmosphere because they are small enough to enter the water cycle, where they are transferred from the marine system to the atmosphere in vast amounts and become a source for the disease COVID-19. thus causing the virus to speed up the spread of the global pandemic.

Humans will eventually suffer from the wrongdoing in the ocean systems because humans are nothing but temporary residents of the planet. Just like what the famous English anthropologist, Jane Goodall, has said, “Every individual matters. Every individual makes a difference.”

8 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.

At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.

Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.

In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.

Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.
