Growing food at home can really help eliminate overuse of harmful pesticides and chemicals. Even if you can't live completely off of what you're able to grow at home, what you can grow at home helps reduce how much farmers need to produce which in turn could help reduce the need to use so many chemicals in farming. You'll also have complete control over how your food is grown, so you can eliminate extra pesticides and chemicals from your food and preserve more nutritional benefits of the food. By growing your food at home, you can have direct control over the amount carbon emissions from the chemicals you may use. Growing even just a small bit of the food you need at home can help reduce our dependency on the vast quantities of pesticides and chemicals we are using that are harming earth.
