Since time immemorial felines have been venerated in America, North and South. Their shapes appear
engraved on ancient artifacts and in the form of modem statues. But in the last century, jaguars, pumas and
other American felines have declined alarmingly in number. So much so, that they may become extinct. As a
result, researchers in Spain and Argentina have embarked on a project for the preservation of ten feline
species in Latin America. For the next three years, they will be working on the creation of two genetic banks
one in Madrid and the other in Buenos Aires, to keep away the threat that looms over these animals.
This threat comes from human activity. Since 1920, the population of Latin America has tripled to 480
million people. A quarter of the forest area has disappeared, and activities such as hunting, fishing, mining
and farming intensify human impact on the environment, so that the natural habitat of these species has been
hugely reduced. The reduction of the habitat reduces the population.
So far, the problem has been addressed by introducing new animals into each region, with problems of
transport and adaptation leading to poor chances of success. Now, the plan is to apply assisted reproduction
techniques, fertilizing females with semen from males from other regions, including various zoos in
Argentina and Spain. Scientists hope that, a few decades into the future, the words jaguar or puma may be
more than mere names and memories.
In your own words and based on the ideas in the text, answer the following questions. (?)
a) Why has the number of felines in South America fallen recently?
The number of felines has decreased because human activities such as mining
or hunting have reduced their natural habitat in the forest, and this implies the reduction of the feline population. 
Ayuda: La respuesta la encontramos en el segundo párrafo,
que nos explica las causas de la caÃda en el número de la población de animales
salvajes.
Vocabulario: "has decreased": ha disminuido; "such as ": como
por ejemplo; "this implies":esto implica.
b) How do Spanish and Argentine scientists plan to help endangered felines?.
Scientists from these two countries will use assisted reproduction techniques, that is, they will create two genetic banks from which female animals will be fertilized with semen from males.
Ayuda: La respuesta se presenta ya en el primer párrafo pero
se desarrolla en el tercer párrafo, en el que nos especifica el procedimiento
de la técnica de reproducción asistida que se empleará con las hembras
Vocabulario:"male": macho ; "female": hembra ; "that is": es decir ; "will be fertilized": serán fecundadas.
