Are rainforest fires natural?
Wildfires and Controlled Burning Wildfires are a natural part of many forest ecosystems, often playing a vital role in their life cycle of renewal. The giant redwoods of California, for example, rely on periodic fires (natural or man-made) to clear undergrowth and germinate their seeds.
Can a forest fire start in the rain?
While wind can help the fire to spread, moisture works against the fire. Moisture, in the form of humidity and precipitation, can slow the fire down and reduce its intensity. Rain and other precipitation raise the amount of moisture in fuels, which suppresses any potential wildfires from breaking out.
What are rainforest fires?

Why is Brazil destroying the rainforest?
Cattle ranching is the leading cause of deforestation in the Amazon rainforest. In Brazil, this has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching. Today the figure in Brazil is closer to 70 percent.
Did the Brazilian government start the fires?
Fires in the rainforest don’t start themselves, but that doesn’t mean they are unusual. Brazil’s National Institute for Space Research (INPE), which tracks fires in the Amazon, reports that the number of fires detected through September 2019 is up nearly 50 percent from the same period in 2018.
Do humans live in the Amazon rainforest?
The number of indigenous people living in the Amazon Basin is poorly quantified, but some 20 million people in 8 Amazon countries and the Department of French Guiana are classified as “indigenous”.
