Each year, thousands of grey whales arrive to give birth to their young in the shelter of Ulloa Bay in Baja California Sur. It is a key location in the specie’s annual migration.
The rich marine ecosystem is also critical to blue whales, humpback whales and other threatened species, such as the loggerhead turtle, which seek food and shelter in the bay. Additionally, it’s home to species of commercial interest, such as clams, lobsters and shrimp.
But a serious threat looms over Ulloa Bay, and the animals and people who depend on its health. The Don Diego mine is set to extract, over 50 years, 350 million tons of phosphate sand from the seabed, in an area equivalent to 60 percent of Mexico City.
The whales and sea turtles that inhabit or transit the area rely on sound to communicate and find food. Large dredging ships used to extract phosphate sand will generate an enormous buzz, altering the environment in ways that modify marine mammal behavior and even threaten species survival.

New study confirms large dams to be a principle source of greenhouse gas emissions
Researchers from the Washington State University found that the world’s reservoirs generate 1.3 percent of all greenhouse gases produced by humankind. The finding confirms once more than large dams are unsustainable energy sources that cause great harm to the climate. Seattle, United States. An important new study by researchers at the Washington State University found that large dams are an “underestimated” source of greenhouse gas. The findings show that all reservoirs, not only those built in tropical zones, release far greater quantities of emissions into the atmosphere than previously believed. According to the study, gases are released from the decomposition of organic matter after artificial reservoirs flood natural areas. In fact, over the course of a year reservoirs were found to generate 1.3 percent of the world’s greenhouse gases (more than all of Canada). Eighty percent of those emissions were methane, a pollutant 34 times stronger than carbon dioxide. “Across the Americas, governments are pushing for the construction of hundreds of new large dams, arguing that dams are clean energy and will help to mitigate climate change,” explained Astrid Puentes Riaño, co-director of the Interamerican Association for Environmental Defense (AIDA). “It’s become increasingly clear that large dams are more of a problem than a solution. World leaders must urgently start to plan and implement alternative energy solutions in order to achieve real progress in the fight against climate change.” Along with a coaltion of civil society organizations, AIDA, Amazon Watch and International Rivers have been insisting for years that operating large hydroelectric projects—such as the Belo Monte Dam in Brazil—causes severe damage to the environment, the climate, and the rights of affected communities. “Large dams are one of the most significant causes of environmental destruction in the Amazon,” said Leila Salazar-López, executive director of Amazon Watch. “In addition to emiting methane, they destroy biodiversity and the ancestral forest of thousands of indigenous and traditional communities that have lived for centuries from river ecosystems. It is imperative to calculate the true costs of large dams to understand all their impacts, and avoid causing more harm than good.” As organizations working to promote real solutions to climate change, we are committed to sharing scientific evidence about the harms of large dams to governments, international bodies, and financial institutions. "The new findings lay to rest the myth of hydropower as a clean source of electricity and underline why large hydropower should not receive climate finance," said Kate Horner, executive director of International Rivers. The results of Washington State University's study must be considered in the inventory of emissions that contribute to climate change, as well as in the execution of program and plans aimed at solving energy needs.

Chile’s Salmon Farms: Sustainability is Impossible
By Florencia Ortúzar Chile is the second largest producer of salmon in the world. For more than 20 years, the industry has put profit above environmental protection. In the absence of government regulation, large-scale salmon farms release contaminating chemicals and create oceanic dead zones. They hurt other species and harm the people and communities that depend on the ocean for sustenance. The situation is bad, but it could get worse as the industry looks to expand into new areas of pristine waters. Bad Practices Salmon farming in Chile will never be sustainable because it requires much more protein to operate than it generates. Salmon are carnivorous. To produce one kilo of salmon you need about five kilos of wild fish for feed. Years of bad business practices and lack of government regulation have resulted in serious environmental damage, which has, in turn, brought grave social consequences to those who depend on seafood for their livelihoods. On the Big Island of Chiloé, for example, seaweed and shellfish gatherers, artisanal fishermen and people who work in plants that process wild-caught fish are experiencing massive unemployment. This social crisis is a direct result of the environmental catastrophe caused in large part by the salmon industry, which has extensive operations in the area. In Chile, developers must present declarations or environmental impact studies that examine their project’s potential to harm nature. Despite the great risk to ecosystems, salmon farms are supported by mere affidavits, and not by studies that would allow for the identification and proper handling of potential negative impacts. The result is thousands of salmon hatcheries. Each one consists of floating cages that, without sufficient spacing or adequate sanitation, house thousands of salmon crammed into small spaces (half the space allowed in Europe). Although it seems difficult to believe, and despite the law saying otherwise, in Chile no studies have been done on the ability of the ocean, lakes, and rivers to accommodate the number of salmon that are grown. These captive salmon are fed pellets that contain a mix of wild fishmeal, pesticides, dyes, fungicides, and chemicals used to speed growth. A majority of these pellets are not consumed and simply fall to the seabed. Additionally, each salmon is injected with an exorbitant quantity of antibiotics (up to 5,000 times more than used in Norway). Finally, the waste generated by the fish, which contains chemicals, also accumulates on the ocean floor. More than 20 years of these practices have caused dead zones in the ocean where life is no longer possible. Another serious problem with the industry is that salmon often escape from their cages. According to a report by the NGO Terram, escaped salmon in Chile represent 1.5 percent of the total production, equivalent to more than 9,000 tons per year. Some studies report that this percentage could reach as high as five percent. Although by law farms must have recapture plans, they rarely succeed. Salmon are an aggressive fish. When free, they compete with native fish for food and shelter, and transmit disease. Crisis in the Sea In May, Chile’s coasts were devastated by an unprecedented red tide, believed to be the country’s worst recent environmental crisis. The natural phenomenon, characterized by an excessive increase in microalgae, resulted in the beaching of whales, squid, sardines and even birds. Captive salmon were also affected and the industry suffered huge losses: thousands of tons of salmon carcasses rotted in floating cages. The death rate was such that the national maritime authority authorized the release of 9,000 tons of dead salmon into the sea. According to the salmon industry and the government, the red tide was caused by El Niño, which was aggravated by global warming. However, some scientists have said that the salmon industry is largely to blame for submitting the ocean to their bad practices for so many years. Patagonia Without Salmon Farming! Not only has the salmon industry not learned from its mistakes, but it is also looking to expand into new, uncontaminated waters. It’s happening in the Patagonia regions of Magallanes and Aysen, where approximately 3,100 applications for salmon farms are awaiting approval. Farms were even proposed for places declared as priority conservation sites. Together with our allies, AIDA is working to ensure salmon farming and other industries comply with environmental standards. But there’s something you can do too, as citizens and consumers. Vote with your pocketbook. By purchasing only sustainable seafood products, you can help prevent the creation of more dead zones in our oceans.

Celebrating hope for oceans
By Gladys Martínez This month I’m celebrating my tenth anniversary with AIDA. For a decade now, I’ve been working for environmental justice and realizing one of my lifelong dreams: defending that which has no voice. In all this time, my best clients have been the oceans and their coasts. Experience has taught me that life depends on the oceans. That’s why I was happy to spend my anniversary working to create a new treaty to protect life in the high seas. The high seas are considered international waters, and because they belong to no country, there is no legal protection for the plants and animals that call them home. A treaty that provided that protection would give a second chance to the oceans and to those who most depend on them: all of us. Time for reflection Throughout my career as an environmental attorney, I’ve worked to limit the negative impacts of illegal and excessive fishing. On behalf of AIDA, and in alliance with our partner organizations, I’ve used international law to promote sustainable fishing and the conservation of wetlands, mangroves, and coral reefs. During the last several years I’ve had the honor of working beside Sandra Moguel, AIDA’s marine attorney in Mexico. Because of Sandra’s dedication and leadership, we’ve been able to preserve Mexico’s ocean, coastline and the communites threatened by short-sighted development. Sandra recently moved on from AIDA to work with our partners at the Mexican Center for Environmental Law (CEMDA), as Director of their Southeast Regional Office. Though I, and all of us at AIDA, will miss having her by our side, her new position fills me with great hope for Mexico, and the fight to defend the country’s rich environmental heritage. Sandra’s work to protect Mexico’s coastal wetlands, rivers, and oceans will not soon be forgotten. We will build upon her successes and continue the fight to preserve our region’s waters and defend the communities that depend upon them. A new hope That fight took me most recently to New York City, with the High Seas Alliance, to assist in the development of the high seas treaty. This year I’ve participated in two sessions of the treaty’s Preparatory Committee, alongside State representatives and civil society. We aim to complete the agreement within two years. It will be implemented under the United Nations Convention on the Law of the Sea. As a representative of AIDA, the only Latin American organization involved in the treaty’s planning meetings, I’m working to ensure the high seas recieve the same protections as the national waters we’ve fought so long to defend. The high seas treaty is a truly collaborative effort that holds great hope for the protection of our planet’s international waters. Responsible to my region As a Costa Rican, I feel a responsibility to care for the natural heritage of Latin America. I also believe in the importance of creating marine reserves in international waters. Doing so would reduce the pressure of fishing on marine resources, create a more balanced environment, and ease the stress ecosystems and their inhabitants face when adapting to climate change. The international waters that surround our region are blessed with many areas of great importance to the high seas, known as “ecologically significant areas.” They are: The Costa Rican Dome. Located in the Pacific Ocean, the Dome is constantly changing location depending on the wind and ocean currents. It houses breeding, feeding, and birthing zones for tuna, blue whales, sharks, dolphins, sea turtles, and many other species. The White Shark Café. Located in the international waters of the Pacific Ocean, between the Baja California Peninsula and Hawaii, the area is a key meeting place for white sharks, a species in great danger, which gather there after leaving the coasts of Mexico and Florida. The Sala y Gomez and Nazca Ridges. Stretching for more than 3,000 kilometers through the southeast Pacific, the ridges extend beyond Chilean waters, where they are protected by the State. Offshore sections remain unprotected, despite the fact that they contain some of the highest levels of marine biodiversity in the world. The ridges shelter blue whales, leatherback sea turtles, swordfish, and Chilean mackerel, among other species. Most of the underwater mountains are still found in their natural state, making protection paramount. The Atlantic Equatorial Fracture Zone. Located between Brazil and the Guinea Basin, this fracture zone belongs to no country. It is a source of food and energy for different species of fish (among them yellowfin tuna, bigeye tuna, and swordfish), as well as for green and leatherback sea turtles. Protecting the high seas is vital to providing a safe space for the feeding, breeding, and growth of many important marine species. As I look forward to another 10 years, my dream remains the same as it ever was: working to protect these great creatures and the waters they call home; giving them a voice; and advocating for the preservation of our region’s greatest natural treasures.
