ページを 3 行拡大して大きな森の木をページに詰め込もうとすると、以下のような結果になります。木がフッターと重なっています。
以下はコードです。フッターと重ならないようにページに詰め込む簡単な方法はありますか? または、以前紹介した複雑なトリックを使わずに 2 つのページに分割する方法はありますか?

を使ってサイズを小さくすることもできます\smallが（ただし読みにくくなります:-）、\thspagestyle{empty}ページ番号を消すこともできます。ただし、そうしたくない場合は、空白を調整してサイズを（ほぼ）合わせることができます。
\enlargethispage*ここでは、ではなくを使用して、\enlaregethispage空白を可能な限り縮小し、オプションを使用して列挙の周囲の空白を調整しましたenumitem。
