Victory: Court ends the “lawful” killing of endangered green sea turtles
In February of 1999, the Constitutional Court in Costa Rica declared an end to the "lawful" killing of endangered green sea turtles. The ruling is an important victory for the green sea turtle and potentially other species left vulnerable by their host countries.
Costa Rica has the privilege and responsibility of being a haven for one of the largest remaining populations of this endangered species of marine turtle in the Atlantic Ocean. Every two or three years, female green sea turtles, many of which are decades old, slowly plod from their ocean homes to nest on a 35 kilometer long beach between the Tortuguero and Parismina River.
Costa Rica, rather than fully protecting these ancient guests, previously had a law allowing for the capture and slaughter of almost two thousand green sea turtles annually. Unfortunately, poachers exploited the law to kill many more than the legal limit, with the survival of the sea turtles jeopardized.
In response to inaction by the Costa Rican government, and to safeguard the survival of the green sea turtle, AIDA worked through its partner organization CEDARENA to file suit and challenge the law.
In the law suit, AIDA and CEDARENA argued that the law violated the Costa Rican constitutional guarantee of an environment that is healthy and “in ecological equilibrium.” We presented hard evidence of the hidden impact of the law on the sea turtles. The Court ruled in our favor, and annulled the law.
The ruling itself does not end the threat to green sea turtles. It may however, provide some breathing room for conservationists to concentrate on stopping illegal poaching. Hopefully, they will succeed.

Photos: Marcela Cintra / Text: Laura Yaniz Since late August, oil has been registered at more than 500 points along 2,500 kilometers of coastline in northeastern Brazil. What began with the appearance of small black spots on some beaches quickly became huge stains that changed the color of the sand itself. The spill’s origin remains unknown, as local organizations and communities organize to clean up their beaches. Far from being resolved, the problem is getting worse every day. The oil’s advance is threatening the marine life in mangroves and coral reefs, both key ecosystems for the survival of species. In addition, residents of the affected communities, who depend on tourism and fishing, have seen their lifestyles and economies threatened. Their health is also at risk due to the consumption of contaminated seafood and direct exposure to the spill. Faced with the inaction of government authorities, the people have been cleaning the beaches and sea with their own hands. The spill itself, coupled with state neglect, violates the human rights of the inhabitants of the hundreds of affected beaches. AIDA—together with the Projeto Publico Institute, Salve Maracaipe, Projeto Caribessa and Rede Minha Jampa—denounced these violations before the Inter-American Commission on Human Rights in an effort to urge the Brazilian government to respond to this social and environmental crisis. Soledad García Muñoz, the Commission's Special Rapporteur on Economic, Social, Cultural and Environmental Rights expressed her solidarity with the Brazilian people and authorities in the face of the tragedy and called on the State to "take the necessary measures to avoid a bigger deterioration of the affected ecosystems, considering that the time, the resources and the way of acting focused on human rights are the key factors for the effectiveness of a contingency plan that the present situation deserves.” She added: “the slower and partial are the measures adopted, more irreparable will be the damages for the Brazilian coast and its biodiversity, as well as for the quality of life of the people that live in these affected regions. It is necessary an urgent and sensible response in face of these serious events generated by the contamination, because that could also accelerate the effects of the climate change in the coast, mangroves, swamps and other ecologically vulnerable habitats.”

Although they occur seasonally each year, respiratory diseases are becoming increasingly severe, said pediatrician Gina Pinilla, who works in Bogotá. As air quality decreases, health complications increase for children who come to the emergency department. What Dr. Pinilla has observed in more than a decade of experience as a doctor is no mere impression. A study conducted by a multidisciplinary team of researchers in Colombia shows that health damage from poor air quality is noticeable from day one. Hospital admissions increase over the first 24 to 72 hours and can extend for almost two weeks. It’s the first multi-city study conducted in Colombia and Latin America to determine the relationship between air pollution and respiratory and circulatory diseases in the population, explained lead researcher Dr. Laura Rodriguez of the Industrial University of Santander. Each contaminant affects us differently One of the findings that most caught the researchers' attention is that harms caused by pollutants are different for children and adults. Children suffer from respiratory diseases, while adults face cardiovascular complications. "Children between 5 and 9 years old face greater impacts and are more likely to have an episode that takes them to the emergency room,” explained Dr. Rodriguez. “But this doesn't mean that the younger ones are unaffected. When a child has respiratory complications, he or she may stay hospitalized for up to a week and be connected to respiratory support. "There are children who need prolonged hospitalizations. For a week, they are dependent on oxygen, whether from a nasal cannula or oxygen machines,” Dr. Pinilla added. “Then they are left with side effects and get sick often." The particular mixture of pollutants found in the air also affects each age group differently. "Pollution in every city has its own behavior: interaction, quantity and the change in makeup between cities," said Dr. Rodriguez. In Bogotá, for example, pollution by sulfur dioxide and particulate matter (PM10 and PM2.5) are related to circulatory diseases in people over 60. Pollution by nitrogen dioxide, sulfur dioxide and PM2.5 particles significantly increases the risk of hospitalization in people under the age of 15. The researcher says that the damage caused by nitrogen dioxide is not given much importance, despite being associated with cardiovascular disease in adults. And, when that pollutant is combined with sulfur dioxide and particulate matter, its effects are enhanced. Pollution harms, even in small quantities An important takeaway from this study is that contaminants can begin to damage public health even before they reach maximum allowable limits. Nitrogen dioxide, for example, is considered harmful, yet regulations have set very high emission limits. "Reaching these limits is very difficult. The city has to be in absurdly high pollution for the alerts to sound," explained Dr. Rodriguez. “The health effects are not related to whether you are exposed to the limits or not, but to the type of mixture you are breathing, because the pollutants are potentiating each other.” In several Latin American cities, regulations allow pollution limits that exceed the recommendations of the World Health Organization (WHO). For example, the WHO recommends a maximum average of 20 µg/m3 (micrograms per cubic meter) of PM10 (solid particles such as ash, soot and dust), but Bogotá has an average of 38 µg/m3. Other cities in the region have even higher annual averages: 40 (Monterrey), 55 (Mexico City), 62 (Lima) and 69 (Santiago). What does this information mean for your city? When poor air quality reaches its most critical levels, hospitals are left without beds and many children with respiratory illnesses remain in the emergency area, explained Dr. Pinilla. It's a common situation because there are no action plans for environmental contingencies. For Dr. Laura Rodriguez, the most important result of her research would be that it helps institutions take action to confront the issue. She recommends local governments and health institutions: Control and regulate the air quality parameters of industrial emissions, and consider monitoring other pollutants. Increase efforts to communicate to the public about the risks of pollution levels in their cities. Prepare hospitals, especially in the first months of the year when pollution reaches its highest level, aggravated by changes in the climate. She emphasized the importance of making intersectoral and multidisciplinary plans and investigations to understand the panorama of air pollution, and to ensure that this information gets into the hands of the appropriate authorities. The study was also conducted by Julián Alfredo Fernández-Niño (U. del Norte, Barranquilla), Néstor Rojas (U. Nacional), Luis Camilo Blanco (U. Santo Tomás) and Víctor Herrera, U. Autónoma de Bucaramanga). Consult it here.
