Cares about the peoples of the world (5)

I believe the answer is:

races

I'm a little stuck... Click here to teach me more about this clue!

'peoples of the world' is the definition.
'races' can be an answer for 'peoples' (I've seen this before). I'm unsure of the 'of the world' bit.

'cares about' is the wordplay.
'about' indicates an anagram.
'cares' anagrammed gives 'RACES'.

'the' acts as a link.

Can you help me to learn more?

(Other definitions for races that I've seen before include "Events at Epsom or Ascot?" , "Speed contests for horses, cars etc" , "Running competitions" , "Speed competitions for various peoples" , "Moves very fast" .)

I've seen this clue in The Globe and Mail.
