This lagoon in Argentina turned pink for a terrible cause | Digital Trends Spanish

Sometimes nature gives us chromatic surprises such as lakes or lagoons that turn pink due to their salinity and the halophilic algae and bacteria that inhabit them. This is not the case of a lagoon in the southern Patagonia region of Argentina. In accordance with Science Alert, the lagoon has been turned bright pink by a tragic environmental accident. And it is that, according to experts and activists, the waters have been contaminated with chemical used to preserve the prawns that are exported from the region to the whole world. The product, called sodium sulphite, is a powerful antibacterial that is used in fish farms and whose waste would have contaminated the Chubut river that feeds the Corfo lagoon 30 km from the coastal city of Trelew and 1,400 km south of Buenos Aires. The lag...

How much do Walmart, Ikea and Amazon pollute with their shipments? | Digital Trends Spanish

A report gives an account of everything that large companies pollute due to their maritime shipments. The figures are surprising, especially since many of these companies recognize themselves as green. Thus, the 15 companies that appear in the report generated almost as much climate pollution in 2019 as the equivalent of 1.5 million homes in a year. The report looks at greenhouse gas emissions and air pollution caused by shipping cargo batteries around the world. Walmart tops the list, generating more greenhouse gas emissions than a coal-fired power plant in a year. Ashley Furniture, Target, Dole and Home Depot round out the top five. Ikea and Amazon rank seven and eight, respectively. Samsung ranks ninth and LG eleventh. The report was released today by the environmental organizatio...

IPhone 12 raises pollution in “iPhone City” | Digital Trends Spanish

The Chinese town of Zhengzhou is colloquially known as the "iPhone City" for being the assembly operations center of the main suppliers of the popular Apple phone. But not everything is hunky with flakes. A report from Morgan Stanley bank warned of a worsening in the city's air quality skyrocketing in recent weeks, an increase that would be associated with industrial activity linked to the mass production of the iPhone 12. According to the analysis of the specialists headed by Katy Huberty, the air quality index has risen significantly as of October 26 in Zhengzhou. Air quality data shows that "industrial production levels have soared more recently, roughly a month after historical seasonality, which we believe coincides with the ramp in iPhone 12 mass production," the analysts wro...

Do birds select the plastic they consume in the ocean? | Digital Trends Spanish

Plastic in the oceans constitutes a serious threat to the different species of seabirds that inhabit these ecosystems. Everything indicates that this environmental problem will continue to get worse. A recent study commissioned by The Pew Charitable Trusts notes that the amount of this material in the ocean could triple by 2040 if the proper measures are not taken. The same reports assures that the plastic can remain in the ocean for hundreds of years and it is likely that it will never biodegrade. Currently, several studies are trying to determine how plastic impacts different species. Seabirds, for example, have been known to consume it, get trapped in it, and also use it to build their nests. Is there a selection? A study of Millennium Nucleus of Ecology and Sustainable Managem...

Resistance to antibiotics linked to contamination | Digital Trends Spanish

Antibiotic resistance is a growing health problem, generally associated with the overuse of these drugs. However, research suggests that it could also be caused by pollution. Using a process known as genomic analysis, scientists from the University of Georgia found a strong correlation between antibiotic resistance and heavy metal contamination. According to research, published in the journal Microbial Biotechnology, the heavy metal soils of the Savannah River had a higher level of specific bacterial hosts as well as antibiotic resistant genes. The bacteria -acidobacteriaoceae, bradyrhizobium and streptomyces- had genes resistant to antibiotics known as ARG for vancomycin, bacitracin, and polymyxin, drugs used to treat infections in humans. Additionally, they had a multidrug resis...
