Fire suppression, in combination with other human-caused environmental changes, may have resulted in unforeseen consequences for natural ecosystems. Some large wildfires in the United States have been blamed on years of fire suppression and the continuing expansion of people into fire-adapted ecosystems as well as climate change. [5]
Pyrocene is a proposed term for a new geologic epoch or age characterized by the influence of human-caused fire activity on Earth. The concept focuses on the many ways humans have applied and removed fire from the Earth, including the burning of fossil fuels and the technologies that have enabled people to leverage their influence and become the dominant species on the planet.
However, human influence caused an increase in fire frequency. Dendrochronological fire scar data and charcoal layer data in Finland suggests that, while many fires occurred during severe drought conditions, an increase in the number of fires during 850 BC and 1660 AD can be attributed to human influence.

And the reality of human development is that people bring fire with them, in electrical lines, cars and barbecue grills. 'Good fires' can help fight fires before they start
Nearly 85% of U.S. wildfires are caused by humans, according to the U.S. Forest Service. Natural causes include lightning and volcanic activity. The Hawaiian Islands have six active volcanoes ...
Fire regimes of United States plants. Savannas have regimes of a few years: blue, pink, and light green areas. When first encountered by Europeans, many ecosystems were the result of repeated fires every one to three years, resulting in the replacement of forests with grassland or savanna, or opening up the forest by removing undergrowth.

Over the course of the year, there were a total of 701 fires, with most started by people and around 215 caused by lightning strikes. Most of the fires were the result of unusual Alaskan weather ...
