For youth climate activists, Earth Day 2020 was going to be epic. Fueled by the global climate strikes that drew millions of young people into streets around the world in 2019, the holiday's historic 50th anniversary held the promise of unprecedented participation and enthusiasm.
Then the pandemic hit. When the ability to hold large gatherings came to a screeching halt in March, just a handful of weeks before Earth Day, events and marches were cancelled. Activists rallied as best they could and managed to pull off an impressive three-day livestream event online, but like everything we've experienced since COVID-19 arrived, it wasn't the same.
Add on climate-focused candidate Bernie Sanders dropping out of the U.S. presidential race in April, and the spring of 2020 was a tough time for youth climate activists. "We just really felt like there was this energy sucked out of the movement," says Katie Eder, 19-year-old founder and Executive Director of Future Coalition. "And there was a lot of cynicism around the election."

Can you make honey without honeybees? According to 12 Israeli students who took home a gold medal in the iGEM (International Genetically Engineered Machine) competition with their synthetic honey project, the answer is yes, you can.
The honey industry faces serious environmental challenges, like the mysterious Colony Collapse Disorder.
For the past year, the team from Technion-Israel Institute of Technology has been working on creating sustainable, artificial honey—no bees required. Why? As the team explains in a video on the project's website, "Studies have shown the amazing nutritional values of honey. However, the honey industry harms the environment, and particularly the bees. That's why vegans don't use honey and why our honey will be a great replacement."
Indeed, honey has long been a controversial product in the vegan community. Some say it's stealing an animal's food source (though bees make more honey than they can possibly use). Some avoid eating honey because it is an animal product and bees' natural habitats are disturbed by humans harvesting it. Others feel that because bees aren't directly killed or harmed in the production of honey, it's not actually unethical to eat.
However, there's no doubt that the honey industry faces some serious environmental challenges. Colony Collapse Disorder, a mysterious phenomenon in which worker bees in colonies disappear in large numbers without any real explanation, came to international attention in 2006. Several explanations from poisonous pesticides to immune-suppressing stress to new or emerging diseases have been posited, but no definitive cause has been found.
There's also the problem of human-managed honey farms having a negative impact on the natural honeybee population.
So how can honey be made without honeybees? It's all about bacteria and enzymes.
The way bees make honey is by collecting nectar from flowers, transporting it in their "honey stomach" (which is separate from their food stomach), and bringing it back to the hive, where it gets transferred from bee mouth to bee mouth. That transferal process reduces the moisture content from about 70 percent to 20 percent, and honey is formed.
The product is still currently under development.
The Technion students created a model of a synthetic honey stomach metabolic pathway, in which the bacterium Bacillus subtilis "learns" to produce honey. "The bacteria can independently control the production of enzymes, eventually achieving a product with the same sugar profile as real honey, and the same health benefits," the team explains. Bacillus subtilis, which is found in soil, vegetation, and our own gastrointestinal tracts, has a natural ability to produce catalase, one of the enzymes needed for honey production. The product is still currently under development.
Whether this project results in a real-world jar of honey we'll be able to buy at the grocery store remains to be seen, but imagine how happy the bees—and vegans—would be if it did.
