Governments must cooperate to ________ the challenge of climate change and reduce carbon emissions.

a. Firstly, our planet faces many challenges, so I’ve started using reusable bags and bottles, turning off unused lights, and using energy-efficient appliances to reduce waste and save energy.

b. I’ve also started supporting local businesses that focus on eco-friendly products and practices.

c. In conclusion, I believe these small steps can lead to a big difference, and I’d love to hear how you’ve been living more sustainably.

d. Dear John, I hope this letter finds you well. I wanted to share my thoughts on living more sustainably, as it has become increasingly important to me.

e. Secondly, I’ve been using public transport more often and planted a few trees in my garden to help improve air quality.

f. Best regards,

Sarah
