IB ESS（Environmental Systems and Societies）是IB科目中的環(huán)境系統(tǒng)和社會(huì)課程，課程主要了解生態(tài)系統(tǒng)和生物群落、生物多樣性和瀕危物種以及人口等內(nèi)容，從實(shí)驗(yàn)室工作和實(shí)驗(yàn)室練習(xí)到實(shí)地考察，再到IB ESS調(diào)查和研究，ESS提供了各種各樣的調(diào)查機(jī)會(huì)。

IB環(huán)境系統(tǒng)和社會(huì)是一門非常流行和實(shí)用的課程。它將提供大量關(guān)于環(huán)境問題、主題以及與環(huán)境和社會(huì)相關(guān)的潛在解決方案的知識。但是，在眾多的主題中選擇一個(gè)IA話題并不容易。

留求藝留學(xué)老師在IB課程內(nèi)部評估寫作方面有多年的經(jīng)驗(yàn)，可以處理環(huán)境研究和社會(huì)中最復(fù)雜的話題。今天，老師也為大家分享了一些IB ESS IA選題，如果你還沒有想法，可以看看能不能找到靈感。
