When we don't understand the connection between ourselves and our bodies, ourselves and our earth, sacrifices feel like hardships and won't have staying power. Before long, the weight is put back on and in the case of the planet, we purchase another round of consumer goods after trying to show care for the Earth by recycling or using cloth grocery bags.
Making a decision to eat right because you care about the health of your body makes it easier to avoid harmful foods. You decide to not consume processed items in order to avoid GMO's or to not eat soy because the estrogen in soy feeds the growth of cancer cells. You form an understanding as to why you are avoiding those foods and are not doing it just because your diet told you to. Understanding brings a desire for long term change.
The same goes for the environment. If you understand we are all a part of the natural world, understand that whatever we do to the earth, we do to ourselves, you don't just hear those words, but feel those words. Buying a big, resource depleting car becomes near impossible to do because you know the impact those resources make on our world, ourselves. You are in relationship with the planet.
I feel all the lists of things we can do to save the planet become meaningless without a connection to our planet. Without feeling we are the planet. Before we can embrace those lists and ideas, we need to form a relationship with our world by spending time outdoors, learning to love the natural world. Only then will we be willing to do the hard work to protect it.
