There is, currently, no possible way to utilise resources without using them up. The purpose of using them in the first place is to gain their qualities.
Steel sheds will hold up to strong winds better and can also be bolted to the ground easier if need be.
they both use up natural resources that could be used for other things
The practice of using Natural Resources that are sustainable means that an item, once used up, can be replaced. Natural resources that are not sustainable are those that, once used, can never be replaced.

Fossil fuels are nonrenewable resources.
Because we are using up resources faster that we are generating them
Once non-renewable resources are used up they will not be replaced, and another resource will need to be found to do what that resource was doing.
The importance of using sustainable resources is to protect our natural resources. Using sustainable resources and materials is good for the environment.Because sustainable basically mean something we can keep doing/using, for generation after generation. Non-sustainable, that's things that will run out. Stuff that our kids, or their kids would have to do without. Kinda egotistic to use things up like that.
