Growing your own food has many positive benefits compared to the ultra-processed foods. Local foods are a staple in my home and its for many reasons. The first reason is that homegrown foods are as close as your backyard, while processed foods travel thousands of miles to reach your closest supermarket. That traveling is usually through ships or planes, then to trucks and cars. All of this traveling combined releases thousands of kg of carbon dioxide. This can be eliminated through simple backyard gardens or your closest farmer market.
The next reason is that by eating grown foods it not only tastes better, but it also is healthier. Next time you buy a fruit at the supermarket that looks as clean as you had just grown it in a greenhouse. Chances are it has had chemicals such as pesticides on it. And if that not enough, there are genetically modified foods, made to grow faster and bigger. This may sound and look like a sold deal, but it had made many shortcuts crucial in the making of an organic food. So next time you go to your supermarket, steer clear of any "too good  to be true" foods. If you go to your nearest farmers market, then you could also be helping your economy, yes the economy. This is because farmers who sell their crops to supermarkets have to pay for shipping and then sell their crops for a low price so that the markets can have a profit. Instead, if you buy from a farmers market, then the farmers sell at full retail and it encourages more farmers to sell locally.
All in all, growing your own foods make sure that 1) it's healthy 2) tastes better 3) helps the environment and 4) helps your local farmers and your economy.  This only scratches the surface in home growing your own food. The benefits of this method outweigh the cons of what supermarkets have churned nowadays.

I think it could be a good idea for people to grow their own food so they would not have to waste the gas and money to drive to the store and buy food, but sometimes people don't know how to grow food or they might not have the right area to do it.

While this is a good idea, it's not always viable. Some plants require a lot of water or care that people just don't have the time or money for. I tried it with our family once and the plants ended up dying and those that lived are overgrown and refuse to bear anything. However, not all GMO foods can be bad. For instance, there is a GMO crop that could provide food for thousands, if not millions more people. This golden rice grows decently quickly and provides huge yields. if developments in the right GMO's continue, world hunger could just be a bad dream. While there are downsides to GMO's, there are also downsides to organic crops. Organic crops don't yield as much of a harvest but some can be more beneficial. Hope you take this into consideration.

This is a good idea however it is not a viable way for a lot of families to live. Many families either do not have the time to grow their own food due to work and school. They also may not have a means to get the right seeds or crops to eat to begin with. As well, you said that it helps for the environment, however many farms that are grown by them selves destroy the top soil because they constantly need food thus ruining the potential for future crops however you were right in saying that they would be saving thousands of kg in transportation.

Yes! I totally agree, all people should give growing there own food a chance. Not only is it healthier for you but it helps you feel more active and energized. After all you are what you eat, and if you eat junk food and other crap what you expect your self to feel like.

I agree, this will be a great change in our society we should focus on locally grown food because it can be more accessible for families and better for the environment. There will be a limitation of harmful green house gasses in the atmosphere because of reduced transportation which can possible slow down global warming. I hope that this problem can change soon and become more affordable for lower income families who cant always have the luxury of obtaining fresh produce.

Hi Hello What are your  lifestyles and family's activities? Also Where you from?

I have a garden in my backyard, and I do much environment work in my community with my family. I am from Castro Vally, California, USA.

I agree Andrew, growing food on any accessible land your family owns is a great way to reduce the amount of energy used to transport food and other goods from places otherwise. Although it may not be very easy to start doing at first, I think that once a family or individual makes it a habit, no matter how small or large the scale of the garden is, it can make a big difference when done by more and more people, even gradually.
