Buying food from other places around the world has a huge affect on our global co2 emissions. It takes a lot of energy to transport said food by boat, truck, plane as well as keeping the food refrigerated, thus creating a lot of carbon. Gardening is a really fun but also contributes way less to your carbon footprint. here are a few benefits; Plants create oxygen, creating more space for biodiversity in your neighbourhood, reduces CO2 emissions from shipping, because now you have grown it yourself instead of buying it from somewhere else, you will not be intaking pesticides from your produce, its good for your mental and physical health, and you will get the satisfaction of growing something yourself. Not everyone has the space or time to garden but it is always good to buy local. By stopping at your local farmers market, not only are you reducing your shipping emissions but also supporting your community and local farmers. Also when shopping at grocery stores you can check to see where the food was grown/made and if it's organic. It makes an impact what you buy. That be said no one can be expected to make and grow everything they eat by hand or to eat entirely locally, and many people rely on transported food to survive. But it's always a good thing to think about when buying food.

Hi, there are still some people who can't grow all their food at home because of the weather, for example. It's not possible to grow a lot of food where I live due to the weather, so it's okay to buy food from other countries. But I also agree with you that we should try to grow as much food as we can ourselves.

I think we might be in the same school Guðrún.
You can absolutely grow potatoes, carrots, beets, probably onions, during summer break, you could grow tomatoes and even grapes year round with a grow lamp, if you have a potato storage room you could even set up a mushroom growing place (please wear a respirator or some kind of a mask) and you could potentially also you could keep 2-4 chickens by making a small chicken coop and you can feed them scraps, leftovers and/or seeds and you can get up tp 4-5 eggs per week per chicken, (this is all assuming you live in a house with your own garden and not an apartment) but if you live in an apartment you can join or get some other people to pitch in to create some kind of a community garden focused on growing homemade food and maybe keeping small livestock (this could cost a bit of money though so i understand if this is not realistic). this is all obviously a ton of work and its much easier to buy local food and vegetables, its very fun if you have the time.
