Growing our own veggies
It’s simple, fun, costs nothing and every single one can do it either in the backyard or even in small balconies. It can also be a great activity with your kids. My mom just makes her own compost with some raw food leftovers intercalated with some leaf litter. After a while, she sows some seeds that she removes from some veggies when cooking or even some potatoes, tomatoes, courgettes among others veggies just naturally grow once they had been buried in the compost.
