Explain the three pillars of sustainable design/development


People
When talking about people it refers to the user, the manufacturer and the people involved at the primary farming level of the products life cycle. The product may change the way a user thinks about how a product is made and it may also inspire thought on how people consider what they buy.

Planet
The effect the product has on the planet as a whole. This takes into account the pollution farming the raw materials, the amount of distance it travels, the method of manufacture, how much power it uses, and the waste it creates. Factors worth considering are what happens when the product is finished with and how far it needs to travel.

Profit
The amount of money the product takes to produce must be covered in the sale of the product. It is impossible to justify investing in a product when it will be at a loss. It is possible to be a non profit making company, but the books still need to be balanced. Profits made can be re-invested in the company to help with expansion.
