We hope that our research results will also lead to efficient and stable food production on Earth that is not affected by typhoons, insect pests or other factors.

This may have some utility for feeding scientists working in Zero G, but it has no value at all for feeding humanity. Not breaking trade links and allowing migrant labour would be a start. As soon as politicians started messing with that courtesy of deglobalisation, Brexit and sanctions, food supplies became ropey. Imagine how much worse it will get as climate change kicks in. Less ideology, more food.

The research is valuable and hopefully lead to many other benefits, but comparing the problems of cultivating things on the planet and the problems of cultivating them on extraterrestrial environments it would seem the first could be solved with a fraction of the investment.

explore food production technology in the extraterrestrial environment such as the moon to realize a "space plant factory."

While on Earth Japan still facing difficulty, like this less than one week ago.

Yes, when the Earth is reduced to a global desert, desperate people will rely on corporations supplying them with food from "space plant factories". Corporate technological solutions will triumph in a glorious future.
