O Ministério Público Federal (MPF) entrou com recurso contra a decisão que manteve a exploração de petróleo na Foz do Amazonas. O órgão alega ausência de estudos climáticos e consulta a povos indígenas, enquanto a Petrobras já se prepara para iniciar a perfuração exploratória.

The Federal Public Ministry (MPF) Filed an Appeal Against the Decision That Maintained Oil Exploration in the Mouth of the Amazon. The Agency Claims Absence of Climatic Studies and Consultation with Indigenous Peoples, While Petrobras is Already Preparing to Begin Exploratory Drilling.

The Federal Public Ministry (MPF) decided to appeal to the Regional Federal Court of the 1st Region (TRF-1) against the decision that maintained the result of the auction for the exploratory blocks of oil in the Amazon River Mouth Basin. The appeal also contests the research license granted to Petrobras, authorizing the start of exploratory activities in the region.

It is worth remembering that last Monday (20), the Brazilian Institute of Environment and Renewable Natural Resources (Ibama) issued the license for the state-owned company to start research operations in the so-called Equatorial Margin, one of the country’s new energy frontiers.

MPF Demands Climatic Studies and Consultation with Indigenous Peoples

According to the MPF, the authorization for oil exploration in the region should be conditioned on the prior completion of a Climate Impact Study (CIS) and an Environmental Assessment of the Sedimentary Area (EASA). Furthermore, the agency emphasizes that prior consultation with indigenous and traditional communities that might be affected is mandatory.

Petrobras Begins Preparations for Exploratory Drilling in the Amazon River Mouth

While the appeal is underway, Petrobras is already preparing to begin exploratory drilling in block FZA-M-059, located in deep waters off the coast of Amapá — about 175 kilometers from the coast and 500 kilometers from the mouth of the Amazon River.

The state-owned company reported that the operation is set to begin “immediately” and will last approximately five months. During this period, the goal is to obtain detailed geological data to assess the potential of the region in terms of oil and natural gas.

In a statement, Petrobras made it clear that “there is no oil production in this phase,” as it is merely an exploratory research stage.

The Amazon River Mouth is one of the most environmentally sensitive areas of the Brazilian coast. The marine biome of the region is home to endangered species and under-researched coral formations, which has raised concerns among environmentalists and scientists.

Therefore, the debate about oil exploration in the Equatorial Margin has become one of the most controversial topics in the Brazilian energy sector, involving divergences between economic development and environmental preservation.

Under nearly 2 kilometers of ice in Antarctica, scientists have discovered an ancient landscape sculpted by rivers up to 60 million years ago, the size of Wales, preserved as a time capsule that could help predict the advance of ice towards the ocean.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

Bricklayers off the scaffolding? New system uses autonomous drones to position bricks and apply adhesive in the air, creating walls with two flying robots working as a team.

For the economist José Kobori, the USA gained a trump card to “blackmail” Brazil and undermine China’s influence by classifying the PCC and Comando Vermelho as terrorists, increasing the power to pressure companies, banks, and even Pix.
