No improvement to this sentence is necessary. It makes perfect sense on its own and sounds right. "Either" always takes an "or" else the word wouldn't make sense, as it's meant to contrast binary options.
eg.
I'm either going to eat food or drink water.

Answer:
Today was a good day, not only for me, but the environment too. On this special day, I got to see my family after a long time, and it was quite delightful. We had such a fun time, all while causing the least pollution to our beloved Earth. There were countless things we had done and I did not regret any of it. For one thing, we used candles, which saved electricity. The only thing I missed was the firecrackers, but that was okay, because it would allow us to live another year. Overall, it was a great time, and the fact that we were also helping the Earth, made it even better.
