Portugal has had a shared
language and close social ties with Brazil since it discovered and started
colonising this huge South American country five centuries ago, but it now
finds itself in danger of suffering an environmental catastrophe, partly
because of the on-going destruction of the Amazon rainforest more than 4,500
kilometres away.
Since 1970, more than 700,000
square kilometres (270,000 square miles) of the rainforest have been destroyed.
That’s about six and a half times the total area of Portugal. The forest
desecration is not only endangering Portugal’s well-being but that of the
entire planet because of its contribution to climate change.
As the Rainforest Alliance
explains, the relationship between deforestation and climate change is simple
but highly significant. “Trees capture greenhouse gasses like carbon dioxide,
preventing them from accumulating in the atmosphere and warming our
planet.
“When we clear forests, we’re not
only knocking out our best ally in capturing the staggering amount of
greenhouse gasses we humans create (which we do primarily by burning fossil
fuels at energy facilities, and of course in cars, planes and trains). We’re
also creating emissions by cutting down trees. When trees are felled, they
release into the atmosphere all the carbon they’ve been storing. What the
deforesters do with the felled trees – either leaving them to rot on the forest
floor or burning them – creates further emissions.”
The Amazon rainforest “has
reached the point of no return,” wrote an environmental activist in Newsweek
magazine. It’s an opinion shared by many others.
According to Bloomberg,
the perpetrators of its demise aren’t just government officials doing the
bidding of Brazil’s far-right President Jair Bolsonaro or the industrial
farmers profiting from tree-cutting. “It’s all about demand, and voracious
consumers the world over are also fuelling the frenzy that is killing the “lungs of the Earth.”
While the Amazon has been a vital
carbon store slowing the pace of global warming, researchers say it has
suffered losses at an accelerated rate since Jair Bolsanaro took office in
January 2019.
“The Brazilian president has encouraged
agriculture and mining activities in the world’s largest rainforest,” in the
words of the BBC.
The destruction is widely recognized as accounting
for 10% to 13% of global CO2 emissions. These emissions are strongly
associated with the conversion of the rainforest into cattle ranching and
agricultural land. Helped by the rampant deforestation, Brazil is the single
biggest exporter of agricultural products to the EU among other places. Many of
these products, such as beef, veal, coffee, sugar, soya beans, cereals and
rice, are produced on deliberately burnt forest terrain after valuable timber
trees are felled and also exported.
If global warming continues as feared, Portugal’s
biodiversity will be massively impacted. In Brazil itself, an estimated 100,000
species have been made extinct in recent years and a great many others
endangered by the deforestation.
There are about 600 Portuguese companies
represented in Brazil. Last year, Portugal imported from its former colony €1.5
billion worth of goods according to the United Nations COMTRADE data
base on international trade. Much of this was likely to have been produced on
deforested land.
Meanwhile, scientists keep reminding us that these
tropical rainforests constitute the main land carbon sink on Earth and are
fundamental in mitigating the effects of climate change and even reducing those
effects.
In July this year it was reported that vast areas
of the Amazon are emitting more carbon than they absorb. According to Greenpeace,
the burning of the rainforest is now releasing huge amounts of carbon into the
atmosphere, and what remains is drying out. This is the tipping point
scientists have been warning us about - beyond which the rainforests will
no longer be able to sustain themselves and will collapse, say Greenpeace.
The World Wild Life Fund (WWF)
explains that the Amazon rainforests have long been recognized as a repository
of ecological services for the rest of the world, but are also the only
rainforests that we have left in terms of size and diversity.
“As forests burn and global warming
worsens, the impact of Amazon deforestation continues to gradually undo the
fragile ecological processes that have been refined over millions of years,”
says the WWF.
The United Nations Cop-26 climate change summit in
Glasgow starting 1st November would offer a good opportunity for
world leaders to combine and ban importing to their countries any products
linked to Amazon deforestation.
