What can we do to reduce the strain of natural resources ?
Use synthetic materials
Why are synthetic matrials better than natural resorces , what is one porblem iwth syntthtic maetials
They last longer and peform better over long periods of time .
They cost more and are harder to make than naterial materials .
How are natural mateirals and synthetics materials that come from the same raw materialds different ?
Synthetic mateirls are chmeiclaly modified befor ebing used .
Why should estimations of resources running out only be expressed int erms of orser of magnitudes ?
The predictions do not take into account the recycling of resources which will be significant in the future.Or how much the future will use , are more altenrtives found ?
