due to clear-cutting of rain forests sumatra and borneo have very little remaining biodiversity

Your statement about Sumatra and Borneo’s biodiversity is on the right track, but it’s not quite as extreme. Here’s a more nuanced breakdown:

Deforestation is a major threat: Clear-cutting rainforests in Sumatra and Borneo has significantly reduced biodiversity. These islands were once home to incredibly diverse ecosystems.

Biodiversity loss is substantial: Studies suggest Southeast Asia, which includes Sumatra and Borneo, has lost over half of its original forest cover. This deforestation is a major driver of biodiversity loss, pushing many species towards endangerment or extinction.

Some biodiversity remains: Despite the deforestation, Sumatra and Borneo still boast remarkable biodiversity. These islands are still home to a significant portion of Indonesia’s known plant and animal species. For example, Borneo alone has over 10,000 flowering plant species.

Here are some additional points to consider:

Conservation efforts: There are ongoing efforts to protect remaining rainforests and promote sustainable practices. These efforts are crucial for preserving biodiversity.

The situation is ongoing: The rate of deforestation is a major concern. Continued efforts are needed to reverse the trend and protect remaining biodiversity.
