It goes without saying, the world is over populated, and shows no sign of population slowing.

Food cost is rising and the impact falls mostly on the poor.

Clearing forests for new farming land has extended enviromental impact, and is unsustainable as a solution. Simply, we are running out of forests.

Somethings gotta give, what will it be?

Something does not add up! Where did you get your data? According to the 2006 Chinese census there were roughly 6,994,500. They estimate the current population in 2008 to be around 7,018,636.

Hong Kong has a total area of 1104km². Subtracting area that are water, that gives you a land area of 1053km².

7,018,636 people ÷ 1053km² = ~6665.371 people/km²

1km² = 1,000,000m²

Therefore there are ~0.00665371 person per sq. meter, not 1.65.

So that means there is 150m² per person.

If you are referring only to Hong Kong Island, then your math is still wrong.
As of the 2006 census there were 1,268,122 residents.
It has a land area of 80.4km².
So you have a density of ~15,772.66/km² or 0.01577 people per sq. meter.

Although that is still way too crowded.
