Climate crisis, air pollution and allergic diseases

The study: Climate changes, air pollution and allergic diseases in childhood and adolescence, published on the Jornal de Pediatria, in its interesting retrospective on the subject, said us: "To analyze the impacts of climate change on the development of immature respiratory and immune systems in children.

The authors of the present study performed a non-systematic review of English, Spanish, and Portuguese articles published in the last five years in databases such as PubMed, EMBASE, and SciELO. The terms used were air pollution OR climate changes OR smoke, AND children OR health.

The increase in the prevalence of some diseases, such as allergic ones, is attributed to the interactions between genetic potential and the environment. However, disordered growth combined with inadequate waste management has caused problems for the planet, such as heatwaves, droughts, forest fires, increased storms and floods, interference in food crops and their nutritional values, changes in the infectious disease pattern, and air pollution resulting from the continuous use of fossil fuels.

Children, beings still in the development stage with immature respiratory and immune systems, are the primary victims of the climate crisis. The authors documented that prenatal and postnatal exposure to ambient air pollutants will accelerate or worsen the morbidity and mortality of many health conditions, including allergic diseases.

Ambient air pollutants change the microbiota, interfere with the immune response, and take direct action on the skin and respiratory epithelium, which facilitates the penetration of allergens. Understanding how the children and adolescent health and well-being are affected by climate change is an urgent matter.

Part of Amazon Rainforest devasted by environmental disaster

Environmental disaster in Ecuador: on January 28th, the fall of a large stone, following a landslide, on a section of a heavy crude oil pipeline caused it to rupture and produced a spill in the Amazon Rainforest of the South American country, causing a natural disaster.

The announcement came during a press conference by Ocp president Jorge Vugdelija and Ecuadorian energy minister Juan Carlos Bermeo. Vugdelija said that the company's technicians have already recovered about 5,300 barrels of oil, equal to 84% of that spilled in the Piedra Fina area, in Napo.

The OCP president said: "We are aware of the gravity of the incident and for this reason we are acting responsibly to minimize its effects. We will not spare resources to carry out a remediation of the affected area and to compensate the community in accordance with the provisions of the law." According to environmental associations, thousands of liters of crude oil were spilled into the Coca River and neighboring waterways.
