Return natural balance的意思|示意

At issue is the balance between two natural phenomena. One is beneficial: as carbon-dioxide levels in the air rise, plants grow more quickly, absorbing more carbon in return.

问题的关键是两种自然现象之间的平衡，有利的一种是：随着空气中二氧化碳含量升高，植物生长得更快，回过头来吸收更多的碳。

When the coastal reclamation is finished, the new coast will reach a new balance gradually, and the deposition in the dock will also return to the natural level gradually.

当围海工程结束，新岸滩调整达平衡后，泊位及港池的回淤将逐渐降至正常自然回淤强度。
