The report "First 100 Days of President José Antonio Kast's Government: Environmental Performance Evaluation" highlights the withdrawal of 43 environmental decrees pending review as a major impact decision on the functioning of the environmental institution. The Foundation urged current authorities to clarify the principles of the ongoing 'Environmental Deconstruction.'

A study published in the scientific journal Frontiers in Plant Science analyzed the post-fire response of these forests in the Maule Region. The findings reveal that the ruil—an endangered species—faces an even greater threat: not only from the direct effects of fire that impacted 9 out of its 15 populations, but also from the massive invasion of pine trees following the blaze.

In the Antofagasta Region, an electric tower from CODELCO (Minidro Hales mine) was installed next to geoglyphs representing the Chakana, an ancient symbol of Andean cosmology over 4,000 years old. The Desierto de Atacama Foundation warns that large-scale mining operations threaten pre-Columbian heritage.

The U.S. multinational Chilean Cobalt Corp. is ramping up its NeoRe rare earth project in Chile, backed by Glencore and Madesal. The Kast government signed an agreement with the U.S. regarding critical minerals amid growing concerns about environmental and territorial impacts.

With support from the municipality's Environmental Unit and a project funded by the Regional Government, trap cameras were acquired through collaboration with the Llay Llay Environmental Committee and Felinos Cerro El Caqui, allowing the documentation of the endangered colo-colo cat (leopardus colocolo), the only national endemic feline, along with other native wildlife.

Exceeding 1.5 °C of warming poses risks of crossing critical tipping points, such as the collapse of ice sheets, permafrost thaw, and disruption of essential ocean currents. This could exacerbate prolonged droughts, torrential rainfall, and heatwaves, severely impacting food security and water availability, leading to catastrophic losses of both terrestrial and marine species.

The Latin American Observatory of Environmental Conflicts (OLCA) reminds us that there has been sustained territorial resistance in Penco-Lirquén for over a decade against the mining initiative by Aclara Resources, driven by communities and organizations seeking to strengthen alternatives related to local commerce, environmental defense, and the productive vocation of the territory.

Scientific evidence underscores that desalination has impacts that cannot be overlooked. The intake of seawater can influence microscopic organisms, eggs, and larvae that make up the foundation of marine food chains. Additionally, the discharge of brine—the hyper-saline waste produced from the process—can disrupt the physical and chemical conditions of sensitive coastal ecosystems, particularly when projects are located in bays with limited water circulation or high biodiversity zones.

One of the major concerns is the population's exposure to fine particulate matter PM 2.5, one of the most harmful pollutants due to its ability to penetrate deeply into the respiratory system and enter the bloodstream. Scientific evidence has linked prolonged exposure to this contaminant with respiratory illnesses, cardiovascular diseases, strokes, lung cancer, and premature deaths, particularly affecting children, the elderly, and individuals with chronic conditions.

According to regional media, a massive march covered Penco and Lirquén this Saturday against Aclara Resources' rare earth project, ahead of Monday's vote. Residents reject the initiative and demand a pollution-free environment.
