原文：Firstly, it is important to consider the impact of climate change on our environment. As temperatures rise and sea levels increase, we can expect to see more extreme weather events and a decline in biodiversity. Secondly, we must explore ways to mitigate these effects by reducing our carbon footprint and promoting sustainable practices. Finally, we need to adapt to the changes that are already happening and prepare for future challenges.

重述：Considering the impact of climate change on our environment is crucial. With rising temperatures and increasing sea levels, we will inevitably face more extreme weather conditions and a loss of biodiversity. We must, therefore, find ways to limit these negative effects by reducing our carbon footprint and promoting sustainable practices. It's also important to adapt to the changes that are already happening and prepare for what may come in the future.
