Advantages and Disadvantages of greenfield sites

Evaluation

It is better not to build on greenfield sites as they clean the air and keep pollution under control, which is hard as a city because it is always expanding for more housing and employment to balance out the workforce however it is also an advantage as there is more space for population growth. Although this is a good thing; it does come with consequences as valuable farmland may be lost which decreases the production rate making food more expensive.
