1.Stop wasting plastic water bottles. Get a re-usable one and do your best to never let it go. (Easy)
2. Buy less of anything in plastic packaging, more produce(using re-usable bags), more bulk bins(using jars) less bullshit. (Easy)
3. Look at anything you are throwing away, can it in any way be re-used or recycled? Can it be donated? Can it be composted? You will end up with almost nothing in there if you are asking this. (Easy)
4. Large corporations are VERY wasteful, and detrimental to the environment in many ways. How can you buy more local? (less packaging, less shipping, less waste) Farmers markets which are much cheaper ( easy, fun, and see #2.), gardening our own food (not easy, but even cheaper, and better), at the least trying to buy from small scale (ethical) local companies in any way possible.
Although not cheaper because they aren't being funded by Monsanto and other factory farms to use their modified (I can't even say crops or food because it isn't.) stuff, which is infecting many local farms with genetically modified pollen (and although the science is being repressed, for some reason millions of bees are dying at the same time...).
Hopefully this is all painfully obvious, but the list of corporations funded by Monsanto is very large, almost any *junkfood* companies will have either corn, or soy, in some way, which if not labeled as organic is almost surely modified by now.
*Proven* toxicology shows that modified foods are safe, yet there is billions of dollars going into stopping laws to allow people to choose what they are eating.
Large corporations do not care about you, they do not care about the Earth. They do not care about telling the truth. They care about getting your money, to the CEO's pocket. At whatever monumental cost to the environment, to our social systems, to our well being.
They don't care. So we have to.
5. Fully embrace that less is more. Donate anything you don't need, to those that are. Use less, get by with less. Minimalism allows you to enjoy life, the less you are worrying about possessions that don't matter anyway. My sister taught me that.
None of this is exaggerated, none of it is extreme, and none of it is hard. Change seems hard, talking your family into change seems harder.
But not as hard as telling your children or grandchildren there used to be a beautiful ocean "back in your day"
