by the u.s. army corps of engineers to pluck out the garbage from the garbage. we're talking about toxic materials, paint, electronics, refrigerators. those had to stay behind so the environmental protection agency can come in and dispose of that appropriately. as for the rest of it, that's all going to landfills, which is leading to another concern. this island produces about 8,500 tons of garbage a day. that's before maria. so all of this debris is now going to be going to these landfills that officials say are already to their capacity. so the question tonight, pamela, what will happen to all this furniture, these electronics, lumber, and of course other organic material get is scooped up off the streets? >> polo sandoval, thank you for your reporting there on the ground in puerto rico. it was an extraordinary sight. five former u.s. presidents sharing the stage at a benefit concert last night, all to raise money for hurricane relief.
