I've lived in climates that get a lot of hail. Florida, for one. Pretty much everyone there still has windows and even skylights.
That's not to say I think the glass house is necessarily a good idea; it's a lot of embodied
energy to be able to grow bananas in Sweden. But it's not the hail that has me worried. Any kind of glass that you could use that much of in a structural way would have to stand up to more than a hailstorm. In a world of declining energy reserves, where we'll be hard pressed to get food on the table and medicine for children, to what lengths
should we be going in order to preserve the luxuries of globalized agroindustry such as tropical fruit in climates to which they are unsuited?
