Final answer:
Intentional food contamination is a global concern due to vulnerability of food supply chains, loss of food diversity, and health risks from exposure to chemicals and medicines.
Step-by-step explanation:
The intentional food contamination has become a global concern due to several factors. Firstly, the globalization of food has made the food supply chains more vulnerable to contamination during production or breaks in the supply chain, which can lead to foodborne illnesses and scarcity. Secondly, the loss of food diversity in our cultures has led to a reliance on mass-produced foods, increasing the risk of contamination. Lastly, the use of food additives and exposure to chemicals and medicines in the food we eat pose health risks to a large number of people.
