= Scarcity = == I predict that if the petroleum is in scarcity the cars wont be able to work because gasoline is made of petroleum and everyone will have to walk because gasoline will be very expencib and not everyone will be able to afford it.And they will have to also use bicycles and everything will look different. == ==I predict that if the wATER couldn't be cleaned and it has a really bad germ we couldn't drink it and there will be a scarcity of clean water.And we would die and someone would have to invent something like sea water getting cleaned without salt. ==
