I watched someone crash their drone in Hawaii 2 days ago

CO2 is not a pollutant! In fact, it is absolutely necessary for life, especially plants, and the current earth is actually CO2 deprived. In geologic terms, CO2 levels were MUCH higher in the past. Further, on this blog, how many Mavics and other UAVs have been lost, and you can't even find a trace of them, even when you know within a few feet of where they apparently landed. Just defies the paranoia that some people have.

Depends on the source, the earths iron oxidising created it, bacteria and later converted some of it into O2, now we're (humans) converting it back and destroying the planets CO2 conversion equipment (trees mainly)

The NPS should have a permit system or a lottery system for using drones in the parks. That way there's accountability and not too many drones being used but it's still a possibility.

Perfect idea. Pick a reasonable number for a particular area and issue permits. Issued online with a nominal fee to cover costs. You'll need to have passed your country's minimum accreditation and if you fly without a permit there's a hefty fine.

Lots of complaints? Reduce the numbers.
