How Maggots Could Lead to More Sustainable Agriculture

A decade ago, two brothers started recycling food waste into feed for animals by letting the food chain run its natural course. In other words—they got into the maggot business. Now their South Africa-based company, AgriProtein, is planning to expand its fly farms into an international network, CNN Money reports.

Jason and David Drew founded their company in 2008 with the goal of cultivating fly larvae (a.k.a. maggots) as an eco-friendly protein source. Today, many farmed animals, such as fish and chicken, are fed fish meal: a type of feed made from dried and ground-up fish. Fish are a cheap protein source, but the high demand for animal feed has led to them being harvested at an unsustainable rate.

AgriProtein's solution to the feed industry's sustainability problem involves tapping into a resource that can be found wherever there's food waste. To create its products, the company's two fly factories in Cape Town and Durban each take in 276 tons of food waste every day. The flies lay 340 million eggs on the waste daily, and those eggs hatch into the maggots used to make the feed.

Theoretically, the process could have wide-reaching effects at every stage of the agriculture industry: Human-generated food waste that would otherwise rot in a landfill is used to nourish the protein, which is then used to feed livestock, which ends up as food for humans.

The Drew brothers' "nutrient recycling" concept attracted research funding from the Bill and Melinda Gates Foundation, and today AgriProtein is valued at more than $200 million. The fly farms are limited to South Africa for now, but the company plans to open 100 factories in Asia, the Middle East, Europe and the United States. If their efforts are successful, the brothers could inspire other insect farmers to embrace the maggot revolution.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
