Why are wildfires increasing?

The number of wildfires have increased due to the complexity of human society and the growing density of population on earth. In ancient times, humans lived in a more primitive world with much less material possessions and technological devices that were prone to malfunctioning or breakage from natural causes such as wind, rain, cold or heat. Humans used fire for warmth, cooking food and protection against predators. Primitive societies had little political power so fires usually burned only small areas.
