And, finally, we have the environmental message, in terms of the record within the Loch Ness sediments.

最后，根据尼斯湖沉积物中的记录，我们得到了环境信息。

But what's different here, thematically speaking that is, is the introduction of Jake as a father, which I think adds an interesting new layer to that rather simplistic environmental message of the first movie.

但不同的是，从主题上来说，是杰克作为父亲的引入，我认为这为第一部电影中相当简单的环境信息增加了一个有趣的新层面。
