It will give you a peace of mind to know that you have a safety net right where you are living in case you needed medicine and for some reason, you are not able to get it.
I believe that having a garden is a blessing, especially if it’s been taken care of. Vegetables are good to have in your garden, but you don’t have to worry about them before hand because you can start growing crops any year.

Having a variety of trees, in my opinion, is very important. Not only the ones that produce fruits but also the ones that have medicinal benefits.
