Climate change has caused extreme changes in the climate, which in the case of Xalapa, allows insects that are characteristic of low areas, such as the one that carries dengue, to now survive in these higher ones. that zone.
The professor of the UV Faculty of Biology, Enrique David Montes de Oca, warned that climate changes affect not only humans but also insects and plants.
In the short and medium term, he said that all living things must adapt or they cannot survive.
Insects affected by climate change
For example, he explained that in Xalapa, now that the climate is warmer, there are insects that have changed their survival area. And that’s important because disease-carrying species, like the Aedes aegypti mosquito, carry the dengue virus.
Historically, remember, in this city people suffering from tropical diseases such as dengue could rest or recover, because the mosquito was in the lower part, but currently this insect remains in the region because the average temperature is hot. The same happens in the case of Zika transmission.
“This means that there is a greater possibility that cases of diseases transmitted by mosquito bites will be recorded in Xalapa, it may not be something common, but the trend is there.”
Professor Enrique David Montes explains that climate change thus includes a series of variables, which not only affect issues such as temperature rise, but also changes in the distribution of distribution of different species of plants and animals.
In the long term, he said, the climate regime is changing and it is not known whether it is part of a global trend or an evolutionary process that has taken place over billions of years. “There is a debate among specialists that this is a normal and natural issue, while there are those who suggest that this phenomenon does not exist.”
He added that regardless of the reasons, what is certain is that its effects are experienced as a society and as a population, whether in rural or urban areas. Although it recognizes that since its appearance, humans have affected the ecosystem and accelerated the climate process.
Regarding the impact on the species, he emphasized that many of the optimal conditions for them have changed. “There are some that adapt more quickly and others that don’t do the same speed and the latter tend to disappear, but it’s a slow process that needs to be studied in depth.”
