  1. 稻子的數學時間

  2. 什麼是糧食自給率? • 國內消費的糧食中,由國內自行生產供應的比例。 • 台灣2012年糧食自給率只有32.7%。

  3. 各項食物的自給率 我們平常所吃的東西中,有多少比例是台灣自己生產的呢?

  4. 主食 • 米飯:91%136.8萬公噸 ÷ 150萬公噸 = 91% • 小麥:0.02%0.03萬公噸 ÷ 137萬公噸 = 0.02%

  5. 蔬菜類 • 葉菜類:91.9%90.5萬公噸 ÷ 98.5萬公噸 = 91.9% • 根菜類:89.5%19.7萬公噸 ÷ 22.1萬公噸 = 89.5% • 莖菜類:85.9%68.6萬公噸 ÷ 79.9萬公噸 = 85.9% • 花果菜類:88.7%54.0萬公噸 ÷ 60.9萬公噸 = 88.7% • 馬鈴薯:13.2%4.5萬公噸 ÷ 34.3萬公噸 = 13.2%

  6. 肉類 • 豬肉:94.2%91萬公噸 ÷ 96.6萬公噸 = 94.2% • 牛肉:5.85%0.6萬公噸 ÷ 10.4萬公噸 = 5.85% • 家禽肉:81.7%63.2萬公噸 ÷ 77.3萬公噸 = 81.7% • 蛋:100%40.5萬公噸 ÷ 40.5萬公噸 = 100%

  7. 水產類 • 魚:199.4%98.7萬公噸 ÷ 49.5萬公噸 = 199.4% • 蝦蟹類:47.0%4.9萬公噸 ÷ 10.5萬公噸 = 47.0% • 貝介類:64.6%10.6萬公噸 ÷ 16.4萬公噸 = 64.6%

  8. 雜糧類 • 大豆:0.009%0.02萬公噸 ÷ 233.6萬公噸 = 0.009% • 玉米:1.5%6.8萬公噸 ÷ 445.8萬公噸 = 1.5% • 台灣每年進口大量大豆與玉米作為牲畜飼料,台灣90%的飼料來自進口雜糧!

  9. 肉類真正的自給率 如果扣除90%的進口飼料,國產的肉類只有10%是真正「國產」的。 • 豬肉:94.2% × 10% = 9.42% • 牛肉:5.85% × 10% = 0.585% • 家禽肉:81.7% × 10% = 8.17% • 蛋:100% × 10% = 10%
