place to start is with our children, encouraging environmental awareness from an early age.

III.

整句是主系表结构，“this will have for the planet's ecosystems”作定语修饰主语the repercussions，主句谓语动词是are，to say the least 退一步说，至少可以说(句中作插入语)。

①The repercussions (影响) this will have for the planet’s ecosystems are catastrophic (毁灭性的) to say the least.

本句的主句是：The repercussions are catastrophic；

“this will have for the planet's ecosystems”是什么成分？定语从句，修饰先行词the repercussions;

to say the least 意思是“往轻里说；至少可以这样说”, 在句中作插入语。

翻译：不夸张地说，这带给我们这个星球生态环境的影响将是毁灭性的。
