Wildfires in the Amazon: Causes, Consequences and How You Can Help

By Liz Wootton

While watching the devastating effects of great swathes of the Brazillian Amazon going up in flames, it’s hard not to be overwhelmed by a deep sense of mind-numbing helplessness. We’re witnessing the beautiful world we live in tragically being destroyed beyond recognition, by the actions of humans who (ironically) also depend on this planet's health to live. But, although it may feel hopeless, Liz Wootton discovers some actions we can all take to help the situation.


Simply put, the delicately-balanced ecosystem of the Amazon produces more than 20% of the world’s oxygen supply and is home to over 50% of the world’s species of plants and animals, as well as around one million indigenous people. The wildfires which are currently sweeping through the world's largest tropical rainforest are annihilating vital resources that the planet cannot afford to lose. 

The flames have been blazing fiercely for over two weeks now, shrouding the city of São Paulo in a dark blanket of smoke. This scale of burning is unprecedented in an area of forest which usually experiences torrential rain and very rarely burns. 

And it’s not just the Amazon we should be worried about. These terrifying wildfires are sweeping through the rest of the world too. California, Greenland, Siberia, Gran Canaria, Alaska and Indonesia, to name a few, are all feeling the devastating effects of their beautiful forests going up in smoke.


Forest fires have always had an important role in nature, clearing out the deadwood and decomposing foliage, thus providing space and nutrients for new trees and plants to grow. However, the unprecedented frequency with which they are currently happening is causing immense damage and disrupting nature's delicately-balanced ecosystems.

This is because the majority of wildfires are now being caused by humans and the consequences of human actions, rather than nature itself. Global warming is a key factor here, with this July being the hottest month ever recorded on the planet. The increase in temperature has led to droughts, water shortages, and vast areas of dry forest land - the perfect conditions for forest fires. Forests that were once lush and teeming with life have been transformed into volatile tinderboxes, where just one little spark can lead to a ferocious fire raging for days, or even weeks.

This is where human carelessness comes into play. It’s predicted that nowadays only 10 - 15% of wildfires are started by natural reasons, which leaves humans responsible for the other 85 - 90%. The causes range from sheer thoughtlessness e.g. leaving a campfire unattended or flicking away a lit cigarette butt, to farmers deliberately starting fires to clear land for cattle or crops or other intentional acts of arson. Whatever the specific circumstances, the results are clear: fundamentally humans are once again causing widespread destruction of the planet due to carelessness, convenience, selfishness or greed. 



⚠ THIS IS AN EMERGENCY ⚠ In this video, you can see the smoke traveling across Brazil. The smoke could be seen and felt by people in urban areas of the country, but this is something that people who live near the Amazon and depend on it for their survival have been going through for years. Companies and the government must stop putting short-term profits over the lives of people and the planet. Head to the link in our bio to demand companies stop forest destruction.

The most obvious effect of wildfires is the utter destruction and devastation they leave in their wake. The loss of human, animal and plant life is a terrible tragedy, as is the annihilation of the land and habitats that these people, animals and plants called home.

As well as eradicating beautiful and complex ecosystems, the fires also lead to the destruction of entire species, some of which will always remain unknown and 'undiscovered'. In Western medicine, around 25% of the drugs we use are derived from plants in the Amazon. However, less than 5% of the plants in the Amazon have actually been studied by scientists, meaning that with the burning of the Amazon, a vast and untapped medicinal potential is also being extinguished. Humanity shoots itself in the foot once again.

Not only do wildfires destroy trees (which, news flash, are doing vital work in helping offset humanity's staggering carbon footprint), the burning of the forests leads to more carbon being released into the atmosphere. The devastating wildfires in Indonesia back in 1997 were said to have generated 25% of global carbon emissions. As well as destroying oxygen-giving plants and trees and releasing more carbon into the atmosphere, the fires also pollute the air for miles around. Leaving local residents breathing in smoke, ash and carbon monoxide, resulting in health issues that stretch well beyond those directly involved in the fire itself. 

Another, less-considered, result of wildfires is the extensive use of water to put them out. As we all know, water is a valuable resource, and having to frequently use great amounts of it to combat the rising level of wildfires is definitely not great news for the world's resources. In addition to this, the soil erosion caused by the vast amounts of water needed to put out the fires further impacts the already damaged land, making recovery and regeneration even more difficult.

This list is by no means exhaustive: wildfires have many consequences and, as they increase due to global warming and deforestation, will continue to damage the planet in myriad unimaginable ways.



The lungs of the Earth are in flames. The Brazilian Amazon—home to 1 million Indigenous people and 3 million species—has been burning for more than two weeks straight. There have been 74,000 fires in the Brazilian Amazon since the beginning of this year—a staggering 84% increase over the same period last year (National Institute for Space Research, Brazil). Scientists and conservationists attribute the accelerating deforestation to President Jair Bolsonaro, who issued an open invitation to loggers and farmers to clear the land after taking office in January.⁣ ⁣ The largest rainforest in the world is a critical piece of the global climate solution. Without the Amazon, we cannot keep the Earth’s warming in check. ⁣ ⁣ The Amazon needs more than our prayers. So what can YOU do?⁣ ⁣ As an emergency response, donate to frontline Amazon groups working to defend the forest. ⁣ Consider becoming a regular supporter of the Rainforest Alliance’s community forestry initiatives across the world’s most vulnerable tropical forests, including the Amazon; this approach is by far the most effective defense against deforestation and natural forest fires, but it requires deep, long-term collaboration between the communities and the public and private sectors.

When election time comes, VOTE for leaders who understand the urgency of our climate crisis and are willing to take bold action—including strong governance and forward-thinking policy.⁣ ⁣ #RainforestAlliance #SaveTheAmazon #PrayForAmazonia #AmazonRainforest #ActOnClimate #ForestsResist #ClimateCrisis : @mohsinkazmitakespictures / Windy.com

The World Wildlife Fund estimates that by 2030 we will have lost over a quarter of the trees in the Amazon if the current rate of deforestation continues unchecked. An outcome which will have drastic consequences for the world we live in. This terrifying statistic highlights the fact that we need to act now, before it’s too late.

Although the wildfires may seem out of our control, we need to keep in mind that they are caused by human actions and therefore human intervention could also help. Here are some ways you can make yourself heard. 

  • Use your voice to share the story of the destruction of the world’s rainforests. Tell your friends, family and colleagues, share the news in whatever way you can: the more people who speak about it, the more it’s likely to be taken seriously.
  • Join and support organisations like the Rainforest Action Network, the Rainforest Alliance, Amazon Team and WWF who work to protect the rainforest and the people, plants and animals who live within it.
  • Sign Greenpeace’s petition to the Brazilian Government, asking them to take measures to save the Amazon rainforest. 
  • Shop ethically and support companies who protect - rather than endanger - the world’s forests.
  • Boycott unsustainably-sourced palm oil.
  • Eat less meat: great chunks of the rainforest are cleared for cattle to graze in and by reducing the world’s demand for meat we can help protect and preserve these precious areas.
  • Act responsibly when you're outdoors: don't leave fires unattended or throw away lit cigarette butts and call out anyone you see doing this.
  • Support politicians and parties who take the environment seriously and who have innovative plans for how we can tackle climate change and the overall destruction of our planet.
  • Try to reduce the amount of paper and cardboard you use.
