Growing your own food
I think growing your own food is one of the easiest and most rewarding ways you can contribute to mother earth.
It helps you become healthy by consuming no pesticide , chemical stimulants.
It Makes your body fitter and mind calmer.
It adds beauty to your small balcony or terrace.
It saves money and gives a direction of life if pursued more seriously.
On a higher note it helps you connect to earth , from which one has come and to which one will get mixed with one day.
On a lighter note , it makes your kid know vegetables by names before the age of 2 and prompt them to eat them too.
