What is this?

How much of this do you eat?

Rice

Rice husk1 bowl = 1000 grains of rice

1 bowl per day x 365 days per year

= 365,000 grains of rice per year

365,000 grains of rice 36,500 grains per kg

= 10 kg per year per person

13,000,000 people in Manila x 10 kg per person = 130,000,000 kg

Rice husk mountain!
