Great question Julie-Ann, thanks for asking!
Organic gardening is better for four main reasons:
First, when you garden organically, you greatly reduce your exposure to pesticides, which have been linked to many severe health problems.
Second, organically-grown food is packed with a higher concentration of nutrients than food grown using conventional modern methods.
Third, organic gardeners tend to use work their areas with hand tools and avoid machines powered by petrol chemicals as much as possible. Gardeners tend to get more exercise and burn more calories while having fun.
And fourth, all of the chemical that you might otherwise put into your gardens goes back in the water cycle at some point, contaminating the ground water, streams, rivers, lakes, and eventually the oceans. Organic gardening is just plain better for the planet.
