When you think Japan, you think sushi. There's a traditional style counter sushi restaurant, but now sushi train restaurants are also popular. You can choose from shrimp, salmon roe, egg, and any number or types of sushi. Recently, you can even order pudding or Korean barbecue. We don't really know why. By the way, the king of sushi in Japan is tuna, with almost two million tons of it fished worldwide every year. Japanese people eat 710,000 ton. That's 1/3 of the world's total. Or Japan consumes 80% of the world's supply of bluefin tuna, in the past 30 years, the total population of tuna has decreased by 1/3. Because of that, the bluefin tuna could soon be designated a threatened species, just like the giant panda, blue whale, tiger and African elephant. Now, for the amount of disposable wooden chopsticks that you use to eat that sushi with, Japanese people use 23 billion pairs of chopsticks per year and every person will throw 200 pairs each. And these days, 90% of those chopsticks are sourced from China. Did you have any idea that Japan was using Chinese natural forest resources to make its disposable wooden chopsticks?
