TRAFFICKING OF WILD SPECIES
Topic I
TRAFFICKING OF WILD SPECIES
* one of the main problems for biodiversity conservation
* widespread in all regions of the world
* the second largest illegal trade (€4-5 billion/year?)
* relation with poverty and inequalities
The human species belongs to the animal kingdom.
For biological reasons, its existence would not be possible without other living creatures.
and, for this reason,
the conscious use of animals, plants and fungi by the people
has existed in all ages and societies…
... as well as unconscious (microorganisms in food or in our bodies…)
prehistoric tools for hunting and fishing
The conscious use takes many forms and has been changing depending on our cultural evolution
... of our lifestyles
…... of our wealth

The most important objectives for the capture of animals have been:
* Obtaining food
Food markets in Saigon (Vietnam) and Dapaong (Togo)
The most important objectives for the capture of animals have been:
* Obtaining food* Domestication (to obtain company, food, help at work, protection…)* Religion- beliefs (rituals, offerings, divination, magical practices...)
superstitioncuring diseases

Animal parts for voodoo rites (Benin, Nigeria…)
The most important objectives for the capture of animals have been:
* Obtaining food* Domestication (to obtain company, food, help at work, protection…)* Religion- beliefs (rituals, offerings, divination, magical practices...)
superstitioncuring diseases
* Fun (spectacles, sports, hunting ...)* Social status (symbols, heraldic, luxury...)* Zoos, museums, collections* Science (research, experimentation…)
The demands have changed over time in each region…and they still vary today between different parts of the world
In this way, in most developed Western countriesanimals are no longer caught in a significant way to

Fun (spectacles, sports, hunting ...)
…although certain uses persist -even illegally- among some people

…in most developed Western countriesthe use of animals caught in the wild is strictly regulated or have been prohibited
Domestication (to obtain company, food, help at work, protection…)Social status (symbols, luxury...)Zoos, museums, collectionsScience (research, experimentation…)
but this regulation raises the price of these animal (often very much) and stimulates illegal trade

However, in less developed societies (for example, rural populations in Africa and Latin América...)
captured animals are mainly used for
FoodTo obtain different materials (skin, bones, fat ...)Religion- beliefs (rituals, offerings, divination, magical practices...)
superstitioncuring diseases
But also for Domestication (to obtain company, food, help at work, protection…)Fun (spectacles, animal fighting...)Social status (symbols, luxury...)
animals are generally captured by people in its immediate surroundings and the money earned for them is reduced
At the same time, in other regions (as the countries of Southeast Asia)millions of animals are caught every year to be used as
Traditional medicineFoodDomestication (working animals, protection…)
But also forFun (spectacles, animal fighting...)Social status (symbols, luxury...)Zoos, museums, collectionsScience (research, experimentation…)
these countries are very densely populated and its environment is very transformed…
…so the capture of animals implies a heavy environmental pressure …and the demand can only be satisfied by the importation
In Asia, traditional medicine is the main concern in relation with threatened species
It is believed that 800 million of people use medicines of this type only in China
The consumption of traditional remedies made of
tiger bone, bear gall bladder, rhinoceros horn, dried geckoes and other animal parts is of huge proportions.
Chinese medicines
The use of animal parts in Chinese medicine is not new,
but the increase in the standard of living has made these remedies available to most people in recent years.
The Chinese culture believes that all parts of the animals can be used as medicine.
The use of endangered tiger products is seen as a symbol of high status and wealth.
Here are some examples of how tiger parts are used:
* Tiger claws: used as a sedative for insomnia * Teeth: used to treat fever * Fat: used to treat leprosy and rheumatism * Nose leather: used to treat superficial wounds such as bites * Tiger bone: used as an anti-inflammatory to treat rheumatism and arthritis,
weakness, headaches, stiffness or paralysis and dysentery * Eyeballs: used to treat epilepsy and malaria * Tail: used to treat skin diseases * Bile: used to treat convulsions in children associated with meningitis * Whiskers: used to treat toothaches * Brain: used to treat laziness and pimples * Penis: used in love potions such as tiger soup, as an aphrodisiac * Dung or feces: used to treat boils, hemorrhoids and cure alcoholism
Are the capture and the trade of living creatures really necessary?taking into account the preceding, there is not a single response
every region of the world presents different biological resourcesdifferent needs (real or perceived)differents situations (political, economic, social awareness…)
We can ban the human consumption of meat from wild animals in Europe
but we can’t in Africa
some species are scarce in some regions but not in othersIs there a need to protect all species in the same way all over the world?
obviously not
eating worms for salebushmeat in a restaurant (Zimbabwe)
Moreover, many people want to possess objects, plants or animals simply because they are scarce
To have something expensive and difficult to obtain gives prestige(as with gold or diamonds)
…and that makes that the more rare is an animal, the more you pay for it…and more people try to catch it
…until its extinction
Can we prevent a person from a poor country trying to sell an animal or a plant for a tourist to get some money?
the problem will persist as long as major economic differences remain between those people:
10€ is not much money for a souvenirbut it is a very important amount for a boy from Brazil or Cambodia
The problem is that the price paid in Asia for a single rhinoceros hornequals the annual income of 275 people in Zambia
How can we prevent that desperately poor people do not try to kill and sell rhinos, elephants, leopards ...?
employees of a national park cutting the horn of a rhino to avoid traffickers kill him
These activitiesare very harmful to the environmentand detrimental to society
therefore, the usual response of governments is to establish mechanisms of control (or prohibition)
which are very difficult to implement effectively
If the sale of animals is forbidden but demand remains…... and if there are people disposed to pay big money for these animals in other countries
... trade will continue to exist illegally

Why does the illegal animal trade is bad?CONSEQUENCES OF ILLEGAL WILDLIFE TRADE
Direct consequences in the COUNTRIES OF ORIGIN:
Illegal trafficking of animals has major implications in ecosystems
pressure on wildlife is very strong → species extinction
It is estimated that only 1 animal in 10 survives the illegal trade
- the mortality is high in the catch, - in many cases the young are caught killing the mother.
Furthermore, - most animals dies in a few weeks due to improper care
Why does the illegal animal trade is bad?CONSEQUENCES OF ILLEGAL WILDLIFE TRADE
Direct consequences in the COUNTRIES OF ORIGIN:
The capture, hunting and removal of animals from the wild is the second threat to the survival of species, after habitat destruction
RUPTURE OF ECOLOGICAL EQUILIBRIUM
Indirect consequences:
As it is illegal, traffic is controlled by criminal organizations…Which bribe the police and authorities to act more easily,
…generating corruptionand causing crime (murders, robberies, gang wars ...)
Moreover, the traffickers need the complicity of some people of indigenous communities who are paid ridiculous amounts per head regardless of the species.

Moreover, the traffickers need the complicity of some people of indigenous communities who are paid ridiculous amounts per head regardless of the species.
For example, a Blue-throated Macaw an endangered bird that lives only in the Pantanal (Bolivia- Brazil),
can cost up to € 50 000 in the U.S. or Europe, but the traders don’t pay more than 20€ to his hunters.
traffic deteriorates the environment but does not enrich the inhabitants…most of the benefit remains in the hands of traffickers
Now, please, try to solve this addition:
Environmental degradation+
more corruption +
more criminality +
negligible benefits=
?
Now, please, make this addition:
Environmental degradation+
more corruption +
more criminality +
negligible benefits=
more poverty / deterioration of living conditions
But illegal wildlife trade has also consequences for the countries of destination:
Many pets escape or are released by their owners…
…when they are able to survive and reproduce, they can be installed permanently becoming invasive species
Invasive species compete with local damaging ecosystemsand causing disturbance to people
Invasive parrots occupying the habitat of pigeons in Madrid Parrot nests in Madrid
In some cases, exotic pets carry diseases that do not exist in destination countries
... and that can be transmitted to humans or threaten the local fauna
Finally, illegal trade allows people to consume traditional remedies
that are generally not effective
…instead of use the modern medicine, science-basedmany people who could be cured die each year for this reason
Illegal trafficking exists in all countries of the worldbut their gravity and evolution are unequal
the main areas of origin are Africa, Southeast Asia and Latin Americathe main destination areas are Southeast Asia (for medicine and food)USA and Europe (pets)Middle East and Persian Gulf (pets, private collections, hunting, shows ...)
Solutions?
* International agreements to regulate the legal trade (which is an important source of revenue for many countries)
* Police checks at borders and airports* Intensify the sanctions not only the traffickers but also to customers
but this will be insufficient
... and the traffic will continue to exist... unless you get reducing
Disparities between rich and poor countries,Lack of environmental awarenessand the irrationality of many people
Discovery of a shipment of death birds by the border police (Italy)
But things can change through culture: in Europe, very recently,* children were told that it was not wrong to kill elephants* children were told it was normal or keep wild animals in captivity* wild animals were caught just for fun* wild animals are caught for food* and medicines were made with animal and plants taken in the wild
Now, all those things have almost disappeared in most advanced countries
Thanks to the culture
Can we move in that direction and around the world?
Topic II
GLOBAL WARMING
Thanks to the fossils we know that terrestrial ecosystems have been changing continuously over time
…and these changes reflect a succession of different types of climates
Fossilized traces of hail
Fossilized plants of cold climates found in Germany
Fossilized remains of a forest in a region that today is occupied by desert (Arizona-USA)
By this,
we know that certain periods have been warmer…
…and other cooler than today,
in accordance with cycles lasting millions of years
But we also know that during the Quaternary the climate has experienced very important alternances (hot-cold) in cycles of about 100,000 years.
cold periods were called "glaciations”,
while hot are called "interglacials"
During the glaciations temperatures were much cooler than current in the middle and high latitudes (dark green and blues in the map),
…but did not change much in the tropics (yellow, brown and red)
…as a result, large areas of land were covered by ice
and sea level dropped more than 100 meters
…exposing large areas that are now submerged
…and generating important changes in the coastline
Ason estuary during the last glaciation and today
These cycles caused major changes in ecosystems:
* large regions that are habitable today were covered with ice or suffered very cold climates,
* while others, that are now deserts, were covered with vegetation
Prehistoric engravings with representations of livestock and wild animals in the Libyan desert
Finally, we also know that climate have shorter fluctuations (a few centuries)…although they are much less important (less than one degree centigrade)
These "minor" fluctuations, have little effect on ecosystems, but have been very important for people throughout history
For example, during the Middle Ages there was a warm phase that allowed the Vikings to colonize Iceland and Greenland
Settlement of viking origin in the Faeroe Islands
... and between the sixteenth and nineteenth centuries there was a cold and very irregular phase
…which has been called the “Little Ice Age" in Europe the winters were exceptionally coldcausing great difficulties to the people (loss of crops, death from cold or hunger ...)
Painting depicting a winter during the Little Ice Age in Belgium
... ports and rivers froze preventing navigationwhich paralyzed trade for long periods each year
Engraving showing the organization of a fair on the frozen River Thames in London (XVII century)
... In some mountain areas glaciers advanced down valleys destroying villages and crops
Position of the glacier of Argentieres today (left) and in the nineteenth century (right). French Alps.
... Northern parts of Europe were abandoned by their inhabitants because agriculture became impossible
In the Scottish Highlands agriculture disappeared as a result of excessive cold and many people had to migrate to more benign regions
... while in Spain many "wells" were built to take advantage of the snow (selling it in cities) in regions where it is very rare today
Remnants of snow pits in Mallorca and Alicante
All this was caused by a difference of no more than 1 º C
¿is 1ºC a big difference?
All changes and fluctuations described so far have a natural originand, therefore, are “normal”
They are caused by physical or astronomical processesand will continue to occur even if humanity disappears
…and they have nothing to do with human activity
Small fluctuations in Earth's orbit characteristics explain most of the climatic cycles
However, over the last century,there has been a break in the "normal" trend of temperatures
that suddenly have begun to increase in an illogical manner

Not exactly, we know that the warming is caused by human activities
that produce contaminationaltering the composition of the atmosphere

Do you see a relationship between the two lines?

Atmospheric content of CO2

The atmosphere is like a greenhouseit retains some of the heat we receive from the sun
and so, we speak of the " greenhouse effect“
if we modify its compositionthe intensity of greenhouse effect changes immediately
The first consequence is a strong increase in temperature
Temperature change for the period 2000 to 2009 relative to the temperatures from 1951 to 1980
but rainfall is also changing…increasing in some regions and declining in others
As well of the intensity of major stormsand the trajectory of some the cyclones:
for the first time in history, a tropical cyclone has hit the Spanish coast and another to those of Uruguay and Southern Brazil
Effects of tropical storm “Delta" in the Canary Islands in 2004
Yes, yes, I know, butIs that really so important?What are the consequences?
the consequences are very diverse and cover many different aspectsfor example, the temperature increase means a reduction in snowfall
and this is forcing the retreat of all the glaciers around the world
Rhone Glacier in the nineteenth century and today (Switzerland)
Ice melting during the dry season is the only source of water in some tropical regions(for example in some areas of Peru, Bolivia, Kenia…)
If the glaciers disappear, people will run out of water
Reduction of the area covered by ice on Mount Kilimanjaro (Tanzania)
In mid latitudes (Europe, USA…) there’s a big concern about the ski resorts: In most of them, the number of "days without snow increases from year to year
Meanwhile, the Arctic sea ice is melting causing major environmental impacts
and endangering many species that need ice (as the polar bears)
Change in precipitation and increased temperatures will cause many regions suffer water stress (lack of water)…
…while in others, the rain can be prejudicial because of excessive
The melting of polar ice and the dilatation of ocean water is producing a general increase in sea level
The melting of polar ice and the dilatation of ocean water is producing a general increase in sea level
This fact leads to beach erosion
Beach erosion in Oyambre (Cantabria). The monument was erected in 1928 in a prairy, away from the sea
The melting of polar ice and the dilatation of ocean water is producing a general increase in sea level
This fact leads to beach erosionand threatens many cities located at sea level in deltas and flat areas
as, for example, Tokyo (Japan)Rio de Janeiro (Brazil)Miami and New Orleans (USA)Alexandria (Egypt)Dacca (Bangladesh)Cotonou (Benin)Lagos (Nigeria)
etc.
Look at the position of the coast at Lagos (Nigeria), depending on sea level
Urbanized areas (in grey)
Sea level (in relation with present)
But the worst can happen in large deltas, very flat and crowdedNile (Egypt), Ganges (Bangladesh), Mekong (Vietnam), Yangtse (China), etc
In these places people do not have place to go
Global warming also produces impacts on ecosystems…at sea (death of corals by excessive temperature ...)
…as on the continentswhere many species must move
toward the poles or towards the summits
looking at lower temperatures
…or change their habits to adapt to new conditionsas some Cantabrian bears that have ceased to hibernate
Other problems are related to agriculture
In general, climate change
…will benefit the regions in middle and high latitudes (which are usually richer countries)
… and harm to the Mediterranean and tropical areas (where there are many poor countries)
In many poor countries, some crops will no be possible and shall be abandoned
Finally, it is foreseeable that certain tropical diseases may extend to regions where they do not exist
During the Quaternary glaciations temperature differences were about 10ºC…but the changes occurred over several thousand of years
During the little ice age the difference was approximately 1ºC
In all these cases ecosystems had time in order to adapt
But now, mathematical models predict a rise in temperatures that could reach 5°C
…in a century
Climate change has never been so fastand you can not to know how ecosystems,
people, society will respond
It is clear that the problem is very seriousbut the economic implications of any measures to stop warming are very important
Most Governments defends the interests of their industries…and do not care to respect international commitments
hoping that others doand that others will pay the bill
Meanwhile, each day that passes the earth becomes more and more sick
something must be doneand, for this,
an agreement between all countries is necessary and very urgent
That is what we expect of you
Ladies and gentlemen, Delegates of the General Assembly
Do not forget to smile
