A study conducted by researchers at the University of Canterbury, New Zealand, determined that one of the reasons why microbes and bacteria have become more resistant is the use of genetically modified products used as herbicides, so their impacts on the use agricultural and domestic needs to be reviewed.
During the scientific conference Balance: 20 years of genetically modified crops and 40 years of genetic engineering, which took place at the Faculty of Sciences of the National Autonomous University of Mexico (UNAM), Jack Heinemann, an academic from the New Zealand university, presented the conclusions of an investigation that analyzed the impacts of different herbicides on microorganisms.
"We live in a world with intensive use of chemicals, there are between 80 thousand and 100 thousand chemicals that are traded and most of them have never analyzed the impact they can have on humans through microbes."
At the conference organized by the Union of Scientists Committed to Society (UCCS) and other networks in America, Europe and Asia, the scientist from the University of Canterbury indicated that among those thousands of chemicals are pesticides, which although they are related with the agro industry, they are 10 times more concentrated in domestic use.
Therefore, if a pet walks through the neighbor's garden and is subsequently caressed by a child or adult, it is exposed to these products. The research made progress in the sense that microorganisms become much more resistant to antibiotics when exposed to herbicides.
“We have seen that the efficacy of antibiotics is undermined, thus increasing the risk that patients may die or have a higher factor of infection. The microorganisms are resistant and help them to live, reproduce more and become resistant to much higher levels of antibiotics, "he concluded.
Elena Álvarez-Buylla, researcher at the UNAM Institute of Ecology and president of the UCCS, asserted that the world is at a key moment to preserve biological and cultural diversity, “both crucial to determine the territories of peoples and to sustain their identity and sovereignty, but also for food security, health and life on the planet ”.
Currently, he regretted, there are the so-called technosciences, where without the support of basic science they are articulated to follow strategies at the service of corporate interests that govern global economic dynamics, which "have impacted and biased scientific work."
The scientists who participate in the networks convening the conference, he emphasized, have the impulse "of a rigorous, critical work with a deep social and environmental commitment, which helps to counteract the current national and global situation characterized by an environmental and social crisis. unprecedented, socioeconomic inequality that continues to deepen, growing technological gap and exercise of power through violence, inability to resolve social conflicts in a rational and peaceful way, increased use of scientific and technological knowledge for war purposes and to satisfy interests of the large multinationals.
