If you're serious... use offsite storage. If you think your house might burn to the ground, and you think your fire safe won't protect optical media, then backup to an offsite location. If you think your house might catch fire and the fire department will come and put out the fire before reaching the limits guaranteed by your safe, then backup to an offsite location because the fire department is going to flood your home with water in the process. If you think your safe is waterproof; and, you live within the 500 year flood zone, backup to offsite storage because a "waterproof safe" won't survive long term immersion... If you're not within the 500 year flood zone, backup to offsite storage anyway because a severe storm may rip the roof off your house and flood it anyway.
There's a theme there. You can't plan for every possibility. Either put the data onto a portable drive and store it in a local bank's safety deposit box; or, encrypt your data and backup to the cloud. Just make sure there's a copy offsite somewhere
This. Grandparent shouldn't have been modded up.
Earth's sustainable population using current tech is somewhere between 9 and 12 billion. People are only going hungry for political reasons. There's plenty of food, it just doesn't get to those who need it. As to energy, there's not enough resources readily available for everyone to live at U.S. levels, which are frankly a bit wasteful; but, it is possible to pull everyone up to a similar standard of living, in time.
Affects of wind turbines on the atmosphere have been studied. Of course they have a localized effect. Short version is the turbines cause local mixing of higher altitude and ground level air, resulting in minor changes to local weather down-wind. The mixing and turbulence will affect pollen and dust in different ways, depending on particle size and where they were (high/low) to begin with. Overall you're pulling heat out of the atmosphere; so, not a bad thing. Turbine numbers would have to get truly massive in order for them to have any significant global effect.
