What are three disadvantages of making and using plastic?
a) it pollutes the land and water.
b) it requires cutting down trees for raw materials.
c) it takes an incredibly long time to break down.
d) it freely conducts heat and electricity.
e) it isn’t easy to recycle.

A), C) , E)

Explanation:

Plastic is a polymeric material that comprises of repeat units of synthetic or non-synthetic organic molecules called monomers.

The strong C-C frame makes it difficult for plastic s to break down. In addition, efficient bacteria that can biodegrade plastics are not known so far. The only way, plastics degrade is via photodegradation i.e. by the absorption of UV rays from sunlight. Plastics in ocean is also a huge problem for marine life. Hence, the disadvantages are:

A) It pollutes the land and water.

C) It takes an incredibly long time to break down.

E) It isn’t easy to recycle.
