Here are some of the things we are doing that to us, don't feel like sacrifices:

1. People say become vegan, but for me personally, that would feel too restricting, so my husband and I stopped eating mammals instead. We still eat chicken, turkey, fish (rarely) and seafood (also rarely).
2. Work remote if able
3. Grow a garden, even if all you can do is a windowsill herb garden. There are so many possibilities you can have. If you have a balcony, you can buy a greenstalk, where you can grow tomatoes, herbs, peppers, strawberries and all kinds of stuff. It doesn't take very much space, and can be very efficient. If you have a little bit of land available, you can have some raised beds or just grow in ground (I am growing with a no dig method for example). You can also put in perenial plants such as blueberries, elder berries, black berries, raspberries, honeyberries and so much more that is really not going to require much of your attention beyong the initial effort of putting it into the ground and then harvesting once the plants start producing.
4. Start sourcing your food locally. The best way of doing this is finding a local CSA (community supported agriculture). We are CSA members of a farm that's literally just a couple and their kids who grow 90% of their own food, and feed the local community too. The stuff you will get from CSA is not only locally grown, but it is the freshest, tastiest produce you will ever have in your life. Sometimes it even ends up saving you some coin, because you are not going through middlemen.
5. Learn cooking from scratch.
6. Don't have kids.

But at the end of the day, you have to remember that you are just one person. Unless corpos decide to make changes, likely nothing we do will truly matter... I do all of these things, because it makes me feel better. Gardening is therapeutic, and you get amazing food out of it. Plus it is a very valuable skill to have, especially given everything happening in the world.
