OKLAHOMA CITY – Rose State College students returning to campus can breathe a little easier in the school’s new student union.

Across the world, drones are being used for large-scale disinfecting of public places, like sports stadiums, that would be too time-consuming for individual staff on the ground. The same case could be made for the student union at Rose State College, a 48,000-square-foot structure that includes a ballroom with seating for 400 people during normal operations.

The college, in collaboration with Total Defense Resource Strategies, demonstrated Monday the use of a drone to disperse a COVID-19 disinfectant at the newly constructed student union that opened this week.

“What we saw today was an innovative new technology, where we use a drone with a canister attached to it to spray a large area, to disinfect it from the virus that causes COVID-19,” said Toney Stricklin, president and CEO of TDRS. “The speed of this is actually such that we can spray 3,500 square feet in as little as three to four minutes.”

Drones Can Reforest The Planet Faster Than Humans Can

There is more than one reason that we need to reforest Planet Earth. Less than a fifth of Earth’s original forests have survived the rise of humans since the last glaciation, and over half of them are in just five countries (see figure below).

The biggest effect from loss of forests is loss of habitat and the resultant loss of biodiversity, even if you don’t care about climate change. We’re burning billions of acres of pristine Indonesian rain forests to plant palm oil trees (Scientific American) just to get a cooking oil with a better shelf life.

Forest biodiversity encompasses not just trees, but the multitude of plants, animals and microorganisms that inhabit forested areas – and their associated genetic diversity. Over a billion humans depend on dense forests for their survival, although all humans depend on forests in some degree for some aspect of their lives.

Forests also are one of the biggest sinks of carbon on Earth, and losing them puts more carbon into the atmosphere and prevents more carbon from being extracted.

According to the International Panel on Climate Change, there remains only about 10 years to prevent the most catastrophic effects of global warming. In 2019, 43 billion tons of CO2 was released by humans into the atmosphere. Planting trees is currently the best way to sequester carbon. But it will take planting many, many billions of trees
