It may come as a surprise to most Americans, but people have been eating insects (entomophagy) for thousands of years, and they are part of the diets of more than 2 billion people. The United Nations predicts that this rapidly growing industry could be worth $6.3 billion by 2030, so bug-based products may soon appear in local stores. Although Western food markets have excluded insects in favor of animal-based protein, insect-based foods offer many health and environmental benefits, especially in light of the pressures from climate change.

Insects produce 80 times less methane than cattle and use less space, feed, water, housing and maintenance. One pound of beef requires 1,850 gallons of water, one pound of chicken uses 500 gallons and one pound of crickets requires one gallon. Nestlé and PepsiCo are conducting research and development forays into the field, and smaller, nimble startups are making plans to introduce new products. Names to watch include Mighty Cricket, Illegal Oats, Jiminy’s, Aspire (Exo Bar), BeoBia and FarmInsect. Public acceptance is expected to be gradual.

The U.S. Department of Agriculture (USDA) has labeled cogongrass (Imperata cylindrica), a native plant of Southeast Asia, as one of the world’s worst invasive weeds. It’s banned as an invasive species by the Federal Noxious Weed Act of 1974, but a study published in the peer-reviewed journal Frontiers in Ecology and the Environment by the University of Massachusetts Amherst discovered that this and about 1,300 other invasive plants are sold at garden centers, nurseries and other retailers.

Lead author Evelyn M. Beaury, a graduate student in organismic and evolutionary biology at University of Massachusetts, says that she and her fellows found cogongrass was being sold by 33 outlets in 17 states. She notes, “This is a tricky case, because plant breeders are marketing a sterile cultivar, but research shows these plants are not completely sterile and can still become invasive.” According to the USDA, there are no known effective biological control methods. Beaury states, “While patchy state regulations definitely contribute to the widespread availability of invasive plants in the U.S., it’s clear we as a public also lack awareness about which plants are invasive and how they spread to new areas. If we want to continue to protect native ecosystems, regulators and managers need more resources to do so.”

Americans use a single recycling stream in which everything goes into one bin to be sorted and cleaned at the designated collection point; a system that requires too much labor with less-than-stellar results. A study conducted by the South Korean SK Group asked 1,500 U.S. adults about sustainable packaging and found that 72 percent prefer products with easily recycled or reused packaging, but don’t understand what can actually be recycled. Forty-two percent were not aware that containers such as plastic bottles cannot be recycled without removing the label. When dirty and labeled recyclables are deposited with clean recyclables, they contaminate the whole batch, creating massive amounts of unnecessary waste.

SKC Inc. has introduced Ecolabel, the first shrink sleeve label that doesn’t need to be removed from plastic bottles to be recycled. This removes the burden from the consumer and recyclers while making the process easier. Recyclops uses independent drivers to service recycling routes, creating income for locals and sustainable living options for residents. They’re innovating the recycling pickup process by using an Uber Eats-type phone app to enable the pickup of recyclables from areas that aren’t being serviced.
