New zealand's natural geography supplies its people with what three sources of income? natural gas petroleum opals timber tourism

New Zealand definitely has some natural gas and pertroleum supplies and it provides around 1/3 of what its people need, but not all of it. But I would choose it as two  of the three sources of income that the question is asking for!

The other one would be Turism.

New Zealand could be a source of timber, but they don't sell it for environmental reasons.

Nation of conflicting ethnic groups

Europe needs to build a trump-like wall that will spread across europe making it impossible for migrants to cross they need to spread pig guts all over this wall so the muslims will never consider crossing into europe..you might be asking "can't they just fly over with planes? " well yes they can so we will install thaad missile protections system to shoot down any aircraft that violates europe's air fourth would be to start a fourth reich in germany.. last but not least.. make europe great again!
