<span><span>Porosity is the amount of empty space in a rock or other earth material (like sand) - in other words, it's how much water a material can hold.
Permeability refers to how well water flows through a material - the flow is controlled by how large the pores are and how well connected the pores are in a given object.</span><span>Therefore, there these are two primary factors that limit the movement and the amount of water (or other fluids) retained in rocks/sedimentary materials.</span></span>
Sharp reduction in agricultural land has been the negative effect of industrialization in China. This scenario occurs because the development of cities to accommodate high population will give way to more lands that will be used for innovations instead for agriculture/food production. This does not only happen in China but also in other parts of the world where the fast increase in their economic growth is going on a fast rate but there are not enough places to accommodate this specific growth.
As a result, lands that are supposed to be for agriculture are maximized by city construction which in the long term might lead to societal hunger.
