Remember~ Do not get overwhelmed, the worse thing you can do is start a bunch of projects at once and end up with to many new things to do.
~Shop at second hand shops. Some times used are just as good as new and cheaper.
~Fix the old broken items. Make sure to use something as long as you can before spending money on a new one.
~Raise/grow your own food. We personally can not have "farm" animals so we use every space we have to grow food.
~Compost One of many ways to keep useful things out of the trash. Also great for a garden and lawn. Below is our small storage compost bin
~Make your own clothes, learn to sew and more. I personally love to crochet.
~Live smaller, down size. Empty space is wasted space. Try to rid yourself of things that just sit and haven't been sued or worn in months.
~Make your own cleaning products and soap. Many different ways to do it, google can be a huge help and Youtube also.
~Learn to fix it yourself. Many times workers charge ways more to fix something then the cost of the items to fix it. You can never learn to much.~Collect rain Make sure its legal in your state first.
~Shop deals. It is not always a option to fix something or barter but shopping deals, looking at a paper or asking around can save you a lot of money.
~Cook from scratch, it is a lot heather that way too.
~Forage for wild food. This comes wit ha "duh" warning to know what you are eating before you just go out and starting eating wild berries and such.
~Can and dehydrate food
~Use cloth instead of disposable ....Like napkins, diapers, and shopping bags
~raise bees They will do wonders for a garden and environment
Over all the best thing you can do is never stop questioning and never stop learning. Question and learn where your water comes from, what it took to make the clothes you wear and of course where your food comes from.
