Eating food that you grew yourself can be extremely satisfying because you know the work that went in to producing the food. You also get the satisfaction of knowing you helped reduce your carbon footprint by a little because the food you grew didn't need to be transported from far away (no trucks or ships) so there were likely little carbon emissions (if any) from it. Same with locally grown food. The produce travels a lot shorter distance to reach you, which means that there are less carbon emissions. Locally grown foods are often organic too, meaning that they don't use synthetic fertilizers and pesticides (I think), which further lowers their environmental impact. The only thing about all this though is that the food is usually more expensive. While those who are lucky enough to be able to afford organic/local produce should definitely do their best to buy it, I think more should be done to help lower the cost of these foods.
