    My mom is an environmentalist. We've always composted (制堆肥） and she's always had some sort of garden. She also never threw anything away because she could see the second __ in it.

I grew into a __ lifestyle. And I started __ my carbon footprint and consumption.

I decided to __ my car for one month in May of 2017. If I needed a car, I was going to borrow someone's to prove that I had the community to __ this decision. I only ended up __ a car once, and I realized it didn't make sense to own a car, __ it and pay for gas. So in September, I fully __ and sold my car.

I also fly a lot for work, and on my __ from the travel agency, it will include how many tons of __ you're emitting (排放） from just your single __, which is like a punch in the gut.

As a result, it has become a __ for me to offset (抵消） my carbon emissions. I __ my carbon emissions, and go onto carbon footprint. com and purchase an offset in the __ of a donation. If we're going to __ the environment this much, we have to be doing something that's going to offset the carbon __ until there's a carbon tax, which I truly hope is __ we will go next.

It’s also really important to talk about what we could see the __ as, because it gets so dark so fast when people talk about __ change.

I don't know what the __ is of me not having a car, but I hope it's something positive that I can't necessarily see.
