I know that, considering the amount of space in Gaza that is undeveloped, and the relative coverage of cities and the
fact that 35% of the buildings have been damaged. So if you look at the coverage and then look at only 35% of that, and know that this includes buildings which predate the use of asbestos, and that not every build was completely covered in asbestos, I estimated that the 31.7 billion given just
between 2005 and 2020 could abate 176 buildings the size of a World Trade Center tower. Maybe I was wrong and Gaza has more than the equivalent of 528 times the amount of building space of which 35% was damaged and ALL of the damaged buildings were built before 1997 and had asbestos in the exact area of any damage. Somehow I doubt that.
Did you have different numbers to rely on?
