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

"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

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:

thanks

You're welcome!

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.

Sure! I'd be happy to help you with your sentences and make them less ambiguous.

First, let's address the first sentence: "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."

To fix the ambiguity, we can separate the sentence into two parts:

1. "One of the main impacts is the transmission of many infectious diseases carried by insects, such as malaria and dengue."

2. "These diseases are sensitive to temperature, humidity, and changes in forest distribution."

By separating the sentence, we make it clear that the first part talks about the main impacts being the transmission of diseases, and the second part explains the specific diseases and their sensitivities.

Now, let's move on to the second sentence: "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.)."

To separate this sentence into two, we need to identify the main ideas and clarify the structure. Here's a revised version:

1. "Alterations in climate may eventually lead to the dislocation of deciduous forests. These forests are primarily composed of trees that lose their leaves seasonally."

2. "The dislocated deciduous forests may move from the south to higher altitudes in the north, replacing coniferous forests (Australian Academy of Science, n.d.)."

By breaking down the sentence, we provide clearer information about the dislocation of deciduous forests and the shift from south to north, as well as the replacement of coniferous forests.

I hope this explanation helps you understand how to fix these sentences and make them less ambiguous! Let me know if you have any further questions.
