In the peri-rural areas and the peri-urban areas, it's not such a big issue. But in Port-au-Prince, it's a tremendous issue. The rubble is taking up so much space that it's very difficult to build a new shelter on a place you have to clear. Clearing it can be very dangerous, as well, so a lot of organizations are loath to get involved in the clearing.
As well, there's this aspect of building back better. I wish I'd brought the pictures of what they call the bidonvilles on the sides of the hills, where people are living. We have to be careful when we do rebuild to build safely and to give a bit of space. That means that some people will not have a roof over their heads in the same area. You can't rebuild better if you build back the way it was.
Rubble removal is a huge issue, and it's still one of the major impediments to building in the greater Port-au-Prince area.
