Maybe you should educate yourself on how conventional fertilizers are created using fossil fuels. Modern day efficient mono-crop farming is only possible due to these fertilizers, that is used to create most of the fast food as well as much of what you see in regular grocery stores. Just do a quick google search on the Haber-Bosch process, which is used to create 500 million tons of fertilizer per year.
Maybe you ought to think twice about buying that fast food lunch, which is likely to have been created using factory farming, deforestation in South America and pesticide-sprayed crops.
Maybe you should consider not buying imported fruit and berries, which was harvested weeks too early and transported thousands of miles to reach your local grocery store.
Maybe you should consider not throwing food in your regular trash, where it gets transported to the landfill where it will generate the release of methane into the atmosphere.
Maybe you should reconsider wasting gallons and gallons of water on a pretty but utterly useless lawn.
How about starting to eat food that is grown locally in sustainable manner? Go to your local farmer's market and shop there instead of buying highly processed garbage "food".
How about you start composting your food scraps, or even better, get some chickens or other animals that you can feed these foods scraps to? That gives awesome eggs as well.
How about starting to grow some of your own food in your garden, if you have one, this will save you money as well as gasoline since that food wont have to be transported long distance in trucks.
How about driving a more fuel efficient car instead of that cool-looking gasoline-hogging monster truck that many Americans like to show off in?
It's all about choices and if you criticize Trump on climate change but you are still making poor choices, then I think you are a hypocrite. Wake up!
I'll finish this post with a picture of one of our many chickens, which we keep in our backyard, where we also grow as much food as we can. I truly believe that if we want to revert the damage done, then it starts with the individual. Don't wait for governments to fix the problems. Do what you can yourself, and vote with your money by buying from sustainable sources.
