This is just a post to go over and summarize my notes taken in my lesson today with my Mandarin tutor.

Recall from memory the words and grammar learned:

塑料 = plastic

污染 = pollution

足够 = enough (adjective)

造成 = to cause something negative to happen

饮用水 = drinkable water

水龙头 = water tap

浪费 = waste

省吃俭用 = to live frugally

有朋自远方来，不亦乐呼 = having a friend from afar come to visit will make you happy

学有所成 = success in studying

Items I was unable to recall:

取之不尽 = inexhaustible

不堪设想 = too dreadful to imagine

主张 = to advocate

社会 = society

工厂 = factory

农场 = farm

人们 = people

普遍 = widespread

离开 = to leave

行为 = behavior

随手 = casually， as you go

流 = to flow

简直 = really (synonymous, but strong than 真的)

Free writing using the vocab and grammar as best I can:

现在的社会需要更重视环境保护。今天人们做很多污染。我们开汽车开得太多了， 用很多水， 和卖很多塑料的东西。人们因该主张更好环保行为。如果现在我们不开始，明天的环境没有饮用水， 好空气， 和好吃的食物。我觉得省吃俭用很难， 但是只好尝试。我们得变化行为。

I tried my best :D
