DOD and United Airlines had a study out last week that backs this up. There was also a report from iata with studies from Airbus, Boeing and Embraer. Flying is almost certainly not as dangerous and people perceive it to be.

Perhaps. But masks are most effective on preventing someone contagious from infecting others and only secondarily in preventing you from being infected. As a result, you may find the risks are higher on airlines that are less strict than Emirates.

Sustainable tourism is a good example that is helping add value to the natural world within the constraints of our capitalist society. When an animal is worth more alive than dead then local people are more likely to protect it. Gorilla Trekking in Rwanada and Uganda are examples where the tourism dollars had greatly reduced poaching in the parks. Sadly things are unravelling without tourism money coming into the country and poaching is on the rise.

Unfortunately there aren't going to be many jobs in this sector currently until COVID-19 is brought more under control.
