Question 2

Not all resources are renewable so its unsustainable to keep using them.

1) Extracting resources -> amount of energy used and waste produced = Unsustainable

2) processing resources into useful materials such as glass often uses energy made from finite resources = Unsustainable

Question 3

Ways of reducing the use of finite resources

Answer 3

1) use less and reduce anything needed to produce it

2) Chemists can develop and adapt processes that use lower amounts of finite resources and reduce damage to the environment, for example chemists have created catalysts that reduce amount of energy required for certain industrial processes
