My teacher told me that this sentence is ambigious. Can someone help me to fix this.

Question

"One of the main impacts is the transmission of many infectious diseases carried by insects, such as malaria and dengue which are sensitive to temperature, humidity, and changes in forest distribution."

And in this sentence my teacher told me try to find the way to separate them into two sentence...but i not sure how to do it. Can someone help me??
"Alterations in climate may eventually lead to the dislocation of deciduous forests, forest composed primarily of trees lose that their leave seasonally, from the south to higher altitudes in the north, replacing coniferous forests (Australian Academy of Science, n.d.)."
Thanks

Answer 1

The main effects are the infectious diseases carried by insects, such as malaria and dengue, which are sensitive to temperature, humidity, and changes in forest distribution.
Not knowing what "effects" are referring to, it's hard to make this sentence much more specific than it is. I've changed a few words and added one comma.

Alterations in climate may eventually lead to the dislocation of deciduous forests in the south to higher altitudes in the north. These trees may replace coniferous forests (Australian Academy of Science, n.d.).
The sentence was far too wordy. Is there really a need to define "deciduous"? I deleted that phrasing.

Basically, you need to work on making your sentences less wordy:

Answer 4

I would make insect-carried modify diseases. I believe that makes the sentence clearer.
The main effects are the infectious, insect-carried diseases , such as malaria and dengue, which are sensitive to temperature, humidity, and changes in forest distribution.
