Improving Paragraph Organization on Climate Change

Read the following paragraph about the effects of climate change:

Sustained increases in global temperatures have profound impacts on natural ecosystems. Many species struggle to adapt to these rapid changes.

These changes not only affect wildlife but also have significant implications for human populations.

However, efforts to mitigate these issues can lead to improvements in public awareness and global collaboration. Awareness initiatives and policies aimed at reducing carbon emissions are crucial in addressing the multifaceted challenges of climate change.
