This document discusses wildfires and forest fires. It begins by explaining the fire triangle of combustible fuel, oxygen, and heat or ignition source needed to start a fire. It then classifies different types of wildfires based on the vegetation involved like brush, bush, veld, and grass fires. The document discusses the environmental effects of wildfires on vegetation, soil, water, air quality, and wildlife. Case studies of wildfire incidents in Uttarakhand, India and California, USA are presented, comparing fatalities, area burned, population density, and other details. The causes of wildfires and questions from the audience are also mentioned.
