I honestly believe that our wonderful planet was really expertly designed. The fact that animal and plant species are dying off all over the globe is due to the fact that its inhabitants think they are more clever than the God who made them. The more that our food crops live in harmony with the wildlife around them including indigenous animals and other plants, the more ''plenty'' we enjoy. We have a diversity of climates and creatures, as well as crops, throughout the world - all suited to their own environment.
For this reason, there are some more discerning gardeners who recognise these facts, grow in accordance with them, and in harmony with all necessary factors to ensure satisfactory husbandry, and use the tools already available to sustain their crops. Crops that are suited to the area where they have always grown. These are tougher crops, and ones that can survive the odds. Sadly the ''scientists'' who meddle with this system are actually destroying what cannot be superseded - improved on.
I prefer to use heirloom seeds. I'll keep my tomatoes red
