<span>According to the ipat model, technology that enhances our acquisition of minerals, fossil fuels, timber, and ocean fish increase environmental impact.
IPAT is a model or equation which expresses that
I (stands for Environmental impact) is the product of three factors: P (stands for population), A (is affluence) and T ( for Technology).
IPAT can be written as (I=PAT) or I = pxAxT</span>
