Traditional fried popcorn is becoming less and less, should be included in the intangible cultural heritage?

It is undeniable that the traditional hand-cranked popcorn carries a lot of 80, 90 people after the memories, I remember when I was a child at the street corner surrounded by a group of children, with the ? The popcorn was made by a group of children on the street, with a bang. A loud bang, the rich flavor dispersed, grab a handful of stuffed into the mouth, not to mention how fragrant, which was the most popular snacks. But it should not be included in the intangible cultural heritage, the reason is very simple, this kind of popcorn is not a healthy food, not recommended for everyone to eat, and there is also pollution of the environment harm.

That old-fashioned stove is made of leaded iron, which is sealed and then heated, and the temperature inside the stove needs to be up to 300 degrees or more before the corn can be popped. And when run at high temperatures, the lead is volatilized exponentially, and all of this toxic material is stuck in the popcorn. Once someone broke down the popcorn under the microscope, per 100 grams of lead is 0.042 mg, do not look not much, but the popcorn is addictive to eat this kind of thing, unknowingly can eat a pound or more. Once the lead intake exceeds the standard, will seriously damage the human kidney metabolic organs. Especially for the metabolic function is not yet fully developed children, it is easy to affect their brain neurodevelopment, and even cause blood diseases, the harm is great.

And the stove used to make popcorn is required to burn a fire to heat. Most of the commonly used burning material is cornstalks or coal and so on, in its burning process will inevitably smoke pollution of the atmosphere. Don't underestimate the pollution, nowadays even charcoal grilled lamb kebabs are banned from selling, let alone popcorn. Each of us must raise awareness of the protection of the environment, to lead by example to support the national environmental policy, even a small pollution can not be produced.

Of course this kind of food is not an unforgivable sin, and it is okay to buy some to satisfy your craving when you meet it by chance. But it does not meet the selection criteria for intangible cultural heritage, unlike lanterns, face painting, wood carving, which have the need for inheritance. And there is no difficulty in operating it, so you can't give it such a high honor.
