The planet might be able to support 30 billion people, but I wouldn't want to live there.
why? you probably wouldn't even notice it. have you travelled across the u.s. and seen how empty it is? sure, some parts of the country and the rest of the world are somewhat crowded - but vast areas of land are virtually empty. but as someone else pointed out, resource distribution would be the main problem. hopefully that will be solved before there are 30 billion people.
