Have a break? from Greenpeace UK on Vimeo.

Oh dear, Nestlé. You didn’t learn anything from Trafigura did you.

Despite getting Greenpeace’s video removed from YouTube, social media has once more made a fool out of a large, well-resourced company by spreading a message faster than their legal department can kill it. In fact, in keeping with the classic rules of the Streisand Effect, by attempting to suppress the story, Nestlé fed the fire. Now Nestlé has released a statement saying that they have replaced Sinar Mas Group as a palm oil supplier and are moving towards sustainable palm oil.

One shock advert and public indignation over Nestlé’s use of irresponsibly sourced palm oil needs to be transformed into wider public awareness of the environmental and social destruction caused by palm oil production. Many tens of thousands of orangutans killed or trafficked in the last ten years, many tens of thousands of other species affected or endangered, irreversible destruction of virgin rainforest, and land use conflicts affecting many thousands of people.

Consider these things, for example, before your next purchase of a KitKat, Galaxy, Dairy Milk, Wrigley’s, Persil, Comfort, Dove, Milkybar, Utterly Butterly, Warburton, Hovis, Kingsmill, Flora, Clover, Special K, Crunchy Nut Cornflakes or Mr Kipling cakes. They all contain palm oil.

Conquistadors, wars, slavery and syphilis won’t help, of course, but cutting down all of your trees is asking for trouble. And yet this is still happening all over the world, notably in Indonesia, where giant swathes of virgin rainforest are being felled and replaced with monoculture crops (specifically the oil palm), and in Brazil and Africa.

In a worrying recent development, a global forestry treaty, REDD (Reducing Emissions from Deforestation and Forest Degradation), due to be signed at the Copenhagen climate change conference this December is set to allow countries to cut down virgin rainforest, plant monoculture crops such as soy and palm oil, call the results forest, and even claim millions in funding for their preservation. Only if essential safeguards preventing deforestation in favour of monoculture crops is restored will the treaty serve to prevent deforestation, instead of effectively subsidising it.

But why is deforestation such a bad idea? We’ve all been hearing about deforestation for years, but what actually happens, why is it so disastrous, and how does deforested land turn into desert?

No two situations are the same, but here are some of the things that happen when you cut down all of your trees:

Habitat fragmentation

Habitat fragmentation is what happens when the preferred physical and biological environment in which an organism or group of organisms live  (their habitat) is broken up. This creates more ‘edge’ or boundary areas with non-preferred habitats, reduces the size of habitats, and alters the micro-climate of each fragmented pocket of habitat. Species immediately become more vulnerable.

Habitat fragmentation in tropical forests is primarily caused by deforestation. Deforestation may be performed for logging, agriculture or rural development, or as a consequence of activities such as oil exploration, mining, road building, and dam construction. Tropical forest habitats may also be fragmented in the longer term by geological or climate change, but the blame for deforestation usually lies at our door.

Species extinction and human cost

Species which would usually avoid living at the edge of their habitat are at greater risk of predation by other species that may avoid venturing within the forest, including humans. The ‘edge effect’ may also increase competition for food and other resources, and a change in microclimate at the habitat edge may cause exposure to higher temperatures and winds, all with less shade and protection. The edge effect is exacerbated the more fragmented the habitat is – like the coast of Norway, there is exponentially more ‘edge’ as time goes by.

Habitat fragmentation leads to smaller habitats, increasing competition for resources, creating a scarcity of some resources and having potentially a far greater impact if species within the food web die off and in turn starve dependant species. Finally, smaller populations of species in fragmented habitats are more susceptible to extinction through decreased genetic diversity and disease.

Assessing the vulnerability of a species within a fragmented forest habitat is difficult, as different species of different sizes have different space requirements, and so may be more or less susceptible to habitat fragmentation and reduced size. Some species may also have a symbiotic relationship with partner species within a habitat which, if lost, will be disastrous for them. Finally, some species simply emigrate to alternate habitats – if you have legs and wings, and you’ve run out of food, it’s time to move.

But this doesn’t always happen. Orangutans are unwilling to leave the canopy even if they’re perched at the top of the last tree in the forest. It also goes without saying that humans affected by deforestation and changes to their habitat may simply have nowhere to go. Tribes may not be able to move for economic, political or social reasons. There are many examples of tribes who, having been displaced from their traditional lands, with no source of income and no means of subsistence, fall into a downward spiral of alcoholism, drug use and despair. Right now, the Ayoreo-Totobiegosode tribe, one of the last uncontacted tribes outside the Amazon, are losing their land to beef production.

Soil erosion and desertification

Exposure to higher temperatures and winds at the habitat edge, without the benefit of plant cover and root systems due to the damage to plant species, leads to soil erosion. In the case of most rainforest environments, the nutrients needed for plant and animal life to continue are stored in the canopy, not the ground. Felling and burning the forest leaves soil bereft of nutritional value, unable to support the vegetation that would bind it together and regulate moisture. Crops grow only with the intensive use of fertilizers, polluting watercourses and causing eutrophication (a buildup of algal plant life which chokes all other plant life).

This erosion has the potential to encroach ever further into fragmented forest habitats, increasing fragmentation and eventually leading to desertification, wiping out entire habitats and driving plant and insect species to extinction. An entire habitat may also be at risk from changes in water flows due to erosion, flooding and increased river levels. Changes in wider climate such as precipitation levels may indiscriminately affect the entire habitat, including the interior.

The Nasca and us

The Nasca disappeared around 1500 years ago, and the recent Cambridge University study suggests that a significant factor in their demise was their destruction of the huarango trees that played such an important role in regulating soil moisture and nutrients. The Nasca, in their drive to plant more crops and to build, destroyed their own environment.

World population in the time of the Nasca was around 300 million. It is now over 6.5 billion. The landscape has changed beyond recognition, but the mistakes the Nasca made are being repeated now, on an exponentially wider scale. What’s different now is that we in the Western world are witnessing the destruction of other tribes, species and environments, to maintain ours. Tribes like the Ayoreo-Totobiegosode, and species like the orangutan, are more vulnerable than the Nasca ever were, because they are shouldering the burden of our consumption.

A report just released by UK organisation Nature Alert in partnership with the Centre for Orangutan Protection highlights the plight of orangutans in Indonesia.

In the last ten years, an estimated 20,000 orangutans have been killed or poached, and not a single prosecution has been brought against any of those responsible. Killing, harming or even moving orangutans is illegal in Indonesia, and orangutans are theoretically protected under the Convention on International Trade in Endangered Species.

Orangutans have been killed, caged, tortured, and traded to countries like Thailand and Cambodia by plantation workers, the military, police and local government officials. Adult orangutan mothers are frequently killed leaving their babies as orphans, unable to fend for themselves.

In the next five years, according to the report, another 10,000 orangutans are at risk of being killed or captured. Those orangutans that are not slaughtered face depletion of their habitat and starvation, and a wide range of other flora and fauna are at risk. This is due to the likely sale of over 2.5 million acres of land in the next five years to companies producing palm oil for biofuels, food, soaps, washing powders, cosmetics, animal feed and other products. Indonesia is the world’s largest palm oil producer.
