I knew that our water consumption was high, we live in an old house that we rent and we don't have a dishwasher. We are also required to keep out lawn green so we have to use a lot of water to keep it green during the summer...
The average is 1,802/gallons per day
Our household is 3,324/gallons per day

Lots of room for improvement! 

For a household of 2 we have a "low" carbon footprint of 3.21 Tons of CO2e/month (the average is 4.00 Tons) 
-We can start eating less meat and having more vegetarian or vegan options.
-Look into trading in our cars for hybrids (long-term goal)
-Carpooling to work more: whether together or with other co-workers

I set a screen time limit on my phone starts 8pm-8am and then it's also a good reminder to read during that time.

I replace screen time with reading a book, I like to read usually before bed because it relaxes me and the screen/TV lights don't keep me awake.

There are ways that you can add to/to subtract from the garments that you currently own. You can learn to sew and take some fashion designing classes to learn how to turn current items into new items.
I've been aware of fast fashion perils for awhile now so I try to be a conscious shopper already. I buy from ethical & sustainable brands and I ask myself if I really need something before buying it, or I borrow from a friend if I am looking to spice up my wardrobe.
