Population, when unchecked, increases in a geometrical ratio. Subsistence only increases in an arithmetical ratio. (Quote by - Thomas Robert Malthus)

I keep telling people I don't see explosive population growth. I do see a heck of a lot of building. (Quote by - Hart Hodges)

That's always a goal: to stop the growth of what is being thrown away. We are always going to have population growth, but if there is more recycling, waste reduction and reuse, hopefully we can hold the line. (Quote by - Jeff Bickford)
