March 37, 2005, Yum! KFC's brands issued a public statement in Shanghai, announcing that Sudan Red (No.1) was found in the inspection of KFC's roasted wings in New Orleans and the seasonings in New Orleans on June 5438+05, and all KFC restaurants in China immediately stopped selling these two products and destroyed all the seasonings. Sudan red is not a food additive. It is a chemical stain, and its chemical composition is a compound called naphthalene, which is also an artificial chemical preparation. Sudan red is an azo chemical dye, which is mainly used to add color to solvents, waxes and gasoline, and to add luster to shoes and floors.

Studies have shown that "Sudan Red 1" is carcinogenic, which will lead to carcinogenesis in rats, and it also shows the characteristics of possible carcinogenicity in the study of human hepatocytes. Because this kind of dye, regarded as food pigment, will only slowly affect the health of consumers and will not cause cancer soon, so it has strong concealment. "Sudan Red 1" is degraded by human body to form a moderately toxic carcinogen "aniline". Excessive "aniline" is inhaled into the human body, which may lead to tissue hypoxia, poor breathing, damage to the central nervous system and cardiovascular system, and even lead to infertility. Animal experiments show that "Sudan Red 1" can cause some cancers in mice, but it is not a serious carcinogen, so there is no need to panic. Sudan red is mainly used (found at present): Chili sauce, Chili oil, spicy radish, pickles and fermented bean curd.

According to the above information, please answer:

(1) What is "Sudan Red 1"? Why does it attract the attention of the whole society?

(2) After reading the materials, how much do you know about food safety? What inspiration did you get from it (about food safety)?

(3) What measures do you think should be taken to control the food problems caused by such substances?

38. According to related reports, most people in a village in yingde city, Guangdong Province will not live beyond 40 years old. After being informed, the Geological Survey Institute of this province carried out the investigation of karst groundwater resources and ecological environment geology in northern Guangdong.

Due to the long-term recycling of polluted water, the health and life of local people have been seriously affected. It can be seen that human activities will affect the environment, and changes in the environment will affect human survival and development. Please answer according to the local ecological environment, actual production or living conditions:

(1) Give an example of human activities destroying the ecological environment.

(2) Put forward an inquiry question for this example.
