Environmental issues

Last Friday, I learnt to some global issues through the presentation by advanced class students.
I listened five presentation about each topics. These are green Products, Diabetes, Melting Ice, Global Companies, and Endangered language.
There are some interesting topics to me, which are Diabetes and Global companies.
First, Diabetes mean a disease in which the body cannot control the level of sugar in the blood.  If people are diagnosed with diabetes when they were seven through twelve years old, they cannot prevent. However, everyone might develop metabolic syndrome. They just only to do a healthy diet.
Second, main global companies are in Mandarin, Spanish, and English. Their financial problem is that produce product money. People use more money than they borrowed. Therefore, people make more money, they affect environment, people health, and cut tree. The way to solve this problem is people need spend less money. That's all.
