Facts about what caused the Amazon rainforest fire?

the Earth’s lungs are burning more than
ever before the Amazon rainforest in Brazil has seen more fires in 2019 than
in any year since researchers began tracking in 2013 what caused this humans
are probably behind the surge wait what about 99% of the Amazons fires were
started because of human actions either on purpose or by accident the world’s
atmosphere is currently holding about 415 parts per million of carbon and the
destruction of the Amazon would add roughly 38 parts per million Lovejoy
estimates it’s a big number almost a 10 percent increase in carbon
apocalyptic as this sounds science suggests it’s not too late to save the
Amazon so let’s get to work what you need to know about the Amazon rainforest
is the Amazon rainforest really Earth’s lungs the answer is yes as the world’s
largest rainforest the Amazon plays a crucial role in keeping our planet’s
carbon dioxide levels in check plants and trees take in carbon dioxide and
release oxygen back into the air in the process of photosynthesis the Amazon
rainforest is typically wet and humid but is subject to both wet and dry
seasons like many other tropical places on earth July and August see the onset
of the dry season and are the region’s driest months with activity peaking by
early September and stopping by mid-november
according to NASA in a typical year that adds up to 200 rainy days gloomy
I know meaning there will be days of heavy rain even in the dry season this
is why the Amazon which covers 2.1 million square miles is often referred
to as the lungs of the planet the forest produces 20% of the oxygen in the
Earth’s atmosphere at least 400 indigenous tribes live in
the rainforest and their cultures and livelihood are intimately linked with
the state of the Amazon last year Raziel witnessed a record number of wildfires
in the Brazilian president share bas enero said that the country’s government
lacks the resources to put these fires out creating more concerns surrounding
brain for his damage and the devastation to lands belonging to indigenous people
but what exactly causes these fires to begin with would you like to know the
truth keep watching season of the koi Mata the
time of year when farmers intentionally set fire to the force and clear the land
for agricultural purposes this is a seasonal cycle called Quay mata farmers
wait for the dry season and they start burning and clearing the area so that
their cattle can graze every year in fact farmers organized a fire day to
burn down the forest for new pasture those fires can then get out of control
dry hot weather helps the flames lightning striking a tree and igniting
it is the most common weather cause for wildfires strong winds can also cause
powerlines to spark which can ignite wildfires if there is dry brush and
grass nearby fire spread and hot dry and windy conditions warmer temperatures and
lower relative humidity make the fuels more receptive to ignition dr. Terry
Clarke senior scientists at the National Center of Atmospheric Research has
developed a computer model that shows how wind moves on a small scale since
1991 he’s been converting these models to
include wildfire characteristics such as fuel and heat exchange between fires and
the atmosphere when hot dry and windy conditions occur simultaneously
wildfires can spread quickly the stronger the wind blows the faster fires
spread the fire generates winds of its own there are as many as 10 times faster
than the ambient wind it can even throw embers into the air
and create additional fires an occurrence called spotting win can also
change the direction of the fire and Gus can raise the fire into the trees
creating a crown fire it may look pretty but it’s very dangerous in addition to
farmers illegal loggers and miners sometimes light fires as well in order
to destroy evidence of their activities bad people in that sense climate change
and uncontrolled rainforest blazes are interconnected since hot dry weather and
decrease rainfall both tied to climate change make the Amazon more vulnerable
to fires the number of fires in the Amazon increased this year as well
sending smoke thousands of miles across the region darkening skies all the way
to South Paulo brazil’s largest city humans are driving these fires either in
a very direct sense or a global sense by changing the ecosystem so much one
expert said deforestation could drive the Amazon to a tipping point in the
Amazon these came out of fires drive deforestation data from Brazilian
satellites indicated that about three football fields worth of Amazonian trees
fell every minute last month oh my goodness just imagine how many trees
that is the total deforested area in July was up 39% from the same month in
the year of 2018 the tropical trees and the fauna they support would disappear
releasing up to a hundred and forty billion tons of stored carbon into the
atmosphere and causing an uptick in already rising global temperatures but
we’ve definitely felt those rising temperatures over the past year many are
deliberately ignited to clear the forests for farming and cattle ranching
Brazil is the largest beef exporter in the world and 80 percent of the soy it
grows in the Amazon goes to animal feed and of course collectively eating less
beef won’t hurt either since demand for beef is what creates the situation to
begin with this years so far scientists have recorded more than 74 thousand
fires in Brazil that’s nearly double 2018 total of about 40,000 fires pretty
much everything is started by humans it’s 2020 why is it important to look
back sometimes you have to look back in order to move forward so why is it
important now once a fire destroys the habitat every animal that relied on it
suffers as well losing shelter and food a lot of carbon
in a big force is contained in its soil layers of organic matter sits on top of
the soil which in turn provides a vital home for small invertebrates all this
organic matter burns up in the wildfires high heat that soil can also move around
across a fire into places it isn’t supposed to be what are you doing here
including into waterways from uncontrolled runoff if nothing changes
soon we can expect a degradation of freshwater systems loss of biodiversity
soil washing into the sea smaller agricultural yields increased
insect infestation and the spread of infectious disease if that wasn’t enough
here’s more on why the region is important there’s an abundance of
animals from pond hopping poisonous frogs to spotted Jaguars slinking around
in the dead of night the Amazon houses some of the world’s most charismatic
plants and animals it’s one of the most diverse ecosystems in the world
home to 10% of the world’s species according to the World Wildlife Fund
there are more than 2.5 million species of insects that scuttled through the
leaf litter not a good place if you’re afraid of bugs but they’re all important
it contains roughly 1300 bird species 3,000 species of fish and approximately
430 species of according to National Geographic these
animals play an important role in keeping the rainforest healthy for
instance important nutrients from the carcasses feces and food scraps
deposited by mammals leach into the forest floor this nutrient influx helps
soil microbes better store carbon instead of releasing it into the
atmosphere there’s a wild variety of plant life more than 40,000 plant
species have been found in the Amazon rainforest chocolate vanilla cinnamon
pepper and coffee all grow in the rainforest rubber trees produce a sticky
white latex sap that holds our planet together and provides a source of income
for indigenous communities living in the rainforest
the Amazons plants play an active role in regulating the ecosystem through a
process called transpiration plan to release water vapor from pores along the
underside of their leaves this moisture influx sustains life by seeding thick
bands of clouds that keep water locked in the lush forests and flowing into the
river that supply communities downstream this phenomenon doesn’t just impact
weather in the Amazon as the rain falls over the forests warm air rises high
into the atmosphere pulling even more moisture in from the ocean thousands of
miles away the Amazon rivers riches the Amazon River is the second longest river
in the world next to the Nile it’s winding waterways cover roughly 4,000
miles according to the US Geological Survey the Amazon has the highest rate
of rainfall in the world according to National Geographic more than 3,700
cubic miles of rainwater fall from the sky each year that’s a lot of water
biodiversity along the Amazon River and its surrounding wetlands is incredibly
rich the winding river is home to numerous species including red-bellied
piranha pancakes stingrays bull sharks black caiman crocodiles and the
endangered pink river dolphin the carbon and oxygen cycle the Amazon
rainforest plays an important part in regulating the world’s oxygen and carbon
cycles it produces roughly six percent of the world’s oxygen and has long been
thought to act as a carbon sink meaning it readily absorbs large amounts of
carbon dioxide from the atmosphere but when trees are logged in the forest is
burned that carbon is released into the atmosphere at alarming rates recent
research has suggested that these forests might actually be emitting more
carbon dioxide than they’re absorbing luckily they were able to conserve large
parts of the fragile ecosystem scientists believe we may be able to
restore its status as a carbon sink to stay up to date with the latest videos
