What we want is a biological control, so the aero-toxins do not kill us. In the end, we will not be killed by the dengue, but we will actually be killed the aero-toxins. We will be killed by aerosols⁴, by the pesticides⁵. So, we have to begin to look for biological mechanisms⁶ and the frog is one of them.

 

Sosa is giving them away, encouraging locals to put them in their gardens. While not everyone has been jumping at the prospect⁷ of taking one home, local residents have been receiving them with amused curiosity. 

 

The truth is that I do not want to take one to my house. I am impressed. But, well, if it is a way to prevent it, what else can I do?

 

Everything serves and its cost is zero, because the repellents are really expensive and not everyone has the money to buy them. 

 

According to a local newspaper, a farmer in a nearby village had the original idea. He was convinced the repopulation of the amphibians⁹ in the heavily forested area would provide a clean answer to the long-legged mosquito. He says that in contrast to the toxic¹⁰ methods wildly used to combat the mosquito, a frog is a friend to the health of people.

 

The frog is a form of defense¹¹. That's the first thing and secondly¹² in my opinion, if I may say, all this chemical stuff and all that is a waste of place, because you know why, because when the insect gets the scent¹³, it goes away from where there is the defense, and the mosquito is no more there. Only when he is a top, or is really caught with the spread, but other than that it doesn't provide anything. He's gone and keeps going. Do you get me? And everything I believe is all this chemical combination does nothing good for the health of the people as it contaminates the air. 

 

A newer strain of the disease appears resistant¹⁴ to the chemical controls, and the amphibian⁸ population continues to decline. Despite the region having large numbers of frogs in the past, today there are very few as a consequence of changes in the natural habitat and years of fumigation¹⁵. Some say the increased air travel as well as Argentina's recent agricultural expansions have played a role in the epidemic¹⁶. Land clearing for food production has disrupted large parts of the country's ecological¹⁷ balance. Despite the enthusiasm for biological controls, there are some words of caution.

 

In accordance with the autonomous¹⁸ population here, it must not be misunderstood that we do not try to introduce species that are not natural to our region, because we have to take care with a representative number in each region, and we have to study them previously¹⁹, because it just might be that they occupy the nests of the native species and with that we would produce a real ecological crisis. 

 

Whether frog heroes or pawns²⁰ in a misguided plan, the amphibian residents of San Luis have been truly thrown into the spotlight²¹.
