Aww that such a beautiful post and I just love that you plant fruit trees to feed yourself, the people around you and the animals. I would love to live in a house in a more tropic country so I can grow my own food.
I try to reduce plastic use as much as I can and work everyday to become more and more minimalistic.
When it comes to food I try to make sure that we eat what we already have in our home and replace ingredients so we can use up what is in our pantries. I don't always succéed but I do feel that I do what I can for our planet. Being vegan, blogging about recipes is also a great way to inspire others to see that there is a choice.
I'm also about to cancel my gym card and do yoga and exercise at home instead = no need for machinery, cleaning products etc that is needed in a gym. My goal is not to get big and bulky so for me that works great.

As you said we all need to think about what we do for the planet. If it's taking the car on unneccesary drives istead of walking or if it's reducing the consumtion of things.
