Organic food is any food product that is produced within the standards of organic farming regulations. The codes that relate to organically produced food vary in different parts of the world, but they have the same aim. One of the key factors in organic food is the restricted use of artificial fertilisers and pesticides, for instance. In fact, in many countries, it must be produced without either of these two materials at all. In addition, certain processes like irradiation tend to be banned. As well as what is not allowed in organic farming, certain practices are commonly encouraged. This includes promoting biodiversity, wildlife management and recycling farm resources, among other measures.
To many people, the purpose of life is very clear. It has been laid out clearly either by their parents, teachers or religious leaders. For others, it is much harder to work out. In fact, many philosophers have argued for centuries about what the true purpose of life is. There is a distinction between what the purpose of any life is and what it means to an individual, of course. Some people believe they have found a purpose in their life if, for example, they do a job that they find fulfilling. To others, the purpose of all human life is to work towards a higher purpose that is bigger than any individual. Broadly speaking, the latter is a spiritual interpretation of a life's purpose.
When computer programs and algorithms mimic the human ability to think, they are said to be using artificial intelligence. The 'intelligence' part of the phrase refers to the ability to build knowledge derived from acquired data. The 'artificial' part refers to the machine that is using that intelligence, usually a computer or, increasingly, a series of computers that can communicate with one another over the internet. The idea is that artificial intelligence will be able to replicate or at least offer something similar to human thought processes in the near future.
