Hi guys! Today, I went to a Chemistry Camp in my school and I want to share an amazing speech given by my teacher, Miss Soh. It is about the "Invisible (and dangerous) Chemistry around us".
Case 1: Poisonous Milk Powder,
Melamine is a cheaper chemical substance which is supposed for industrial uses. Since Melamine can increase the protein content in their milk powder product, companies added Melamine just to decrease their cost and increase their profit. However, Melamine can destroy babies' urinary system and even caused death.
Case 2: Poisonous Bubbled Milk Tea,
Adding Plasticizer into jams, bubbled milk tea can make a food more "viscous", and can attract more consumers to buy their products. However, Plasticizer can harm human's Thyroid Gland and Livers. It can also effect children's growth development.
I only share these two cases, there are more terrible cases if you went to search on the internet. I shared these because I think most of you may probably involved in a scientific carrier later or now. Science may make the world a better place, but the two cases above is the dark side of it. These only happen if a scientist use their knowledge in an evil way, either for profits or personal issues. In Biology, some scientist are still keeping the bacteria of smallpox disease which is now become extinct among human beings for experimental uses, if one day they use it in an evil way, like spreading it all over the world, it will again be a crisis to us. In Physics, Albert Einstein's designs for the atomic bomb later used by other people as a war item is also another example.
I'm not saying that you all will become one of them, just sharing my view on a responsible scientist. What do you think?
