Answer:
Forest fires are a natural and necessary part of the ecosystem. Even healthy forests contain dead trees and decaying plant matter; when a fire turns them to ashes, nutrients return to the soil instead of remaining captive in old vegetation.

They can break down nutrients and minerals in burning plants and other debris such as old logs, leaves and dense undergrowth and restore them to the soil, thus making for a more fertile area.
According to the Scientific Method, in order to make a controlled experiment you NEED to have an hypothesis.
A controlled experiment consists of a test done by a scientist in which only one or a few variables are changed while the others remain constant in order to prove or disprove a hypothesis.

Without a clear hypothesis, the outcome of the experimentation will not be valid nor specific.

conversation about the Black Lives Matter Movement, and the legacy that sparked it, with one of the world's leading experts on policing
Professor Daniel Nagin is the 2014 recipient of the prestigious Stockholm Prize on Criminology, an elected fellow of the American Society of Criminology, and the Teresa and H. John Heinz III University Professor of Public Policy and Statistics. His research focuses on the evolution of criminal and antisocial behaviors over the life course the deterrent effect of criminal and non-criminal penalties on illegal behaviors, and the development of statistical methods for analyzing longitudinal data.
In the wake of recent incidences of lethal violence involving law enforcement officials in Baton Rouge, Falcon Heights, and Dallas, we sat down with Nagin to talk to him about what factors led to these events, why there is apparent mistrust between citizens and law enforcement officials, and what policy, research, and training measures can be taken to help prevent these situations in the future.
