In fact, there are also significant environmental issues like the overuse air condition that causes the temperature increasing.

In fact, there are issues that deserve more attention than species extinction. Climate change and water contamination are just two of these major concerns.

▲ 原句中的also本意用来提供更多额外信息，但该句不构成与上文的附加关系，而应该是比较关系：谁更严重。

▲ 不使用significant替换考官给的important，直接更换为更具备词义细节、更包含负面评价色彩的词汇去修饰issues，如threatening、severe、deserve more attention等 

▲ like用来举例细化上文的alarming issues有哪些，所以列出问题即可，不必要再解释环境问题形成的原因。

▲ 措辞要准确且搭配合理，the overuse of air condition是中英文都说不通的一个短语，temperature increasing不如改成climate change。
