Why do we not need a survey?

After much discussion that our team, had with the teacher in charge (Ms Lum),

we have decided that our project does not need a survey because our project is

about the decomposition of natural plastic that is not normally done by the 

society that is now using the plastic that is made from chemicals. This project

can show whether or not this natural plastic and help the enviroment with 

global warming. This natural decomposition of plastic is not normally done

by other people as the plastic is normally taken for granted, not knowing the

harmful effects that it cause, and thats why the survey for this experiment is

not needed.
