諷刺畫的歷史淵遠流長，最早可溯源自西元前1360年，其諷刺的題材既深且廣，舉凡政治、宗教、社會寫實等，深刻影響到後世對於思想的表達形式，諷刺畫現今成為一般大眾表達自我思惟及批判的一種方法，常見於平面報章雜誌及網路平台等；透過視覺的傳達，強而有力的畫面張力，比起生冷的文字更能吸引閱讀者的注意力。　　
社會環境涵蓋人類文化、科技、政治、經濟等，為人類文明和物質發展的總和，與自然生態環境息息相關，故本研究以此為諷刺題材，探討自然生態與科技發展對我們生活型態的改變與影響。
本研究首先分析諷刺及插畫的定義，及符號學相關理論。接著探討當代諷刺插畫的表現形式，匯整結論後進行本研究創作。本研究主要探討生態環保及社會環境兩大議題，搜集相關議題資料後，選取適合發展的題材並帶入諷刺技巧及文化符碼進行繪製。
本研究發現：(一) 色調及彩度的搭配運用可有效突顯主題。(二)「物」可轉換為符號，與諷刺技巧相結合運用。(三)同一種符號可經由不同的諷刺技巧呈現，創造不同的效果。
