Preventing an Ecological Disaster
By PAM BERNS
Recent, yet-to-be-released UN reports have found that if the world’s
3,000 largest companies were required to pay for the damage and use of
the environment, nearly a third of their profits would be lost,
according to the Guardian/UK.
One study found that harmful environmental practices combined by these
companies would cost more than $2.2 trillion in 2008 alone. Half of
that amount is due to greenhouse gases. If that isn’t shocking enough,
this amount does not cover the related costs of damage like particulate
matter in the air, freshwater pollution, toxic waste clean-up and the
costs that impact societies such as mass migration of displaced people.
Special adviser to the UN Environment Programmes and economist Pavan
Sukhdev “is likely to argue for abolition of billions of dollars of
subsidies to harmful industries like agriculture, energy and transport”
and suggests that tougher regulations and taxes will prompt concerned
governments and the large companies that damage the environment to take
actions to avoid these repercussions.
The earthquake in Haiti brought that country to the world’s
attention. What we saw there was not only the crumbled infrastructure,
but also a country that has been an ecological nightmare for decades
and a political hellhole since its inception. In 1923, well over 60
percent of the country was forest. By 2006, forests covered a mere 2
percent of Haiti. It is difficult to understand how such a devastating
loss of forestation could occur, but there were several forces at work
that spurred the loss. These serve as an illustration of how small
countries like Haiti, Madagascar and Costa Rica, as well as the massive
rainforest of Brazil, are vulnerable to economic and ecological
catastrophes. The domino effect of natural disasters like Haiti’s
repeated hurricanes, killer storms and quakes left downed trees
throughout the country. This then led to massive logging for more wood
and charcoal for fuel—competition for scarce resources to satisfy a
growing population. Meanwhile, Haiti was ordered to pay reparations to
the French to compensate heirs of the ousted plantation owners, forcing
the country into staggering debt. The deforestation also caused soil
erosion. The loss of topsoil triggered flooding and mudslides during
tropical storms in 2004, 2008 and again this year. This has also led to
desertification. Poor farmers have migrated to the slums of
Port-au-Prince. This does not have to happen.
It is our responsibility to protect the forests in our own country,
as well as the rainforests and the rest of the world’s mangroves. When
we define forests, we often think of trees, but many species are
supported by forests. Forests are made up of trees whose upper branches
spread to create a kind of canopy that envelops the flora and fauna
that reside there. When we disrupt any part of this habitat by logging,
over-harvesting the plants or culling undergrowth for charcoal, we
upset the delicate balance of life. By protecting our forests, we
protect an ecosystem that we all rely on for our medicines and forest
products for our future. Without managing our forests, we will continue
to destroy the 140 rainforest-inhabiting species that are lost every
day.
The Amazon jungle is a 1.7 billion-acre basin in South America, of
which 1.4 billion acres are rainforest, encompassing nine countries,
including Brazil, Peru, and Colombia—making it more than half of the
world’s rainforest in an unbroken tract of land. It hosts over “75,000
kinds of trees and 150,000 species of higher plants,” according to
Conservation Biology.
Since the 1960s, cultivation of crops involved the slash-and-burn
method of clearing the land of forest. The term “slash-and-burn” refers
to the practice of cutting down the trees and then burning what
remains, creating land that is free of parasites. For a brief time, the
ash created by burning is used for farming or cattle grazing. However,
in a short time, the soil is left depleted and infertile for more than
a decade, therefore causing poor farmers to seek new areas to
slash-and-burn. Since the 1970s, the cleared land has become lost to
pasture for cattle due to our demand for lower-priced beef and
soybeans. These markets created a need for transportation into
deforested areas, and new roads have fragmented the existing forests,
disrupting the habitat. Precious rainforest land is exploited for the
profitable hamburger and chopstick markets, along with illegally logged
wood purchased by businesses that do not even realize that the wood is
illegally harvested. Planting new trees will never replace old forests
and the species that the forest provides. And many times, well-meaning
people plant different trees than the originals. This will not replace
a lost forest. It is gone forever.
National Geographic predicts that we will lose more than 40 percent
of the Amazon Rainforest in the next 20 years. Unfortunately, if more
measures are not put in the hands of those who protect the area, the
loss of the rainforest will accelerate global warming, and the higher
temperatures will lead to less rainfall and more desertification.
Unfortunately, in the last few years, the Amazon basin has experienced
severe drought.
According to Nature, “One hectare [2.47 acres] in the Peruvian
Amazons has been calculated to have a value of $6,820 if intact forest
is sustainably harvested for fruits, latex and timber; $1,000 if
clear-cut for commercial timber (not sustainably harvested); or $148 if
used as cattle pasture.” And for this we threaten our future?
Despite Brazil’s President Luiz Inacio Lula da Silva’s good
intentions in 2008 of setting goals to combat deforestation,
slashing-and-burning to accommodate cattle-raising has accelerated.
We let our rainforests disappear at our own peril. More than 100
prescription drugs are derived from rainforest plants. There are
literally thousands of tropical rainforest plants that have not been
tested for their medicinal properties, according to E/The Environmental
Magazine. They cite the now-extinct periwinkle plant that came from
Madagascar, which “increased the chances of survival for children with
leukemia from 20 percent to 80 percent.”
