Explanation:
Hardin's metaphor describes a lifeboat bearing 50 people, with room for ten more. The lifeboat is in an ocean surrounded by a hundred swimmers. The "ethics" of the situation stem from the dilemma of whether (and under what circumstances) swimmers should be taken aboard the lifeboat.
Hardin compared the lifeboat metaphor to the Spaceship Earth model of resource distribution, which he criticizes by asserting that a spaceship would be directed by a single leader – a captain – which the Earth lacks. Hardin asserts that the spaceship model leads to the tragedy of the commons. In contrast, the lifeboat metaphor presents individual lifeboats as rich nations and the swimmers as poor nations.
you could split the boys in half by 2 groups of 7 then use one of those seven group and add it to the 21 girls which is 28. Then divide 28 by 7 and you get 4. So there is 5 with 7 members in each. A more easy way of doing it is adding 14 and 21 together and you get 35 and 7x5 is 35. You can also do 7 groups of 5.
