The South American Amazon is home to countless plants, insects, and animals, as well as hundreds of thousands of natives. For centuries, the Oriente region of the Ecuadorian Amazon was considered a paradise for its inhabitants: they were very proud of their ancestral land. However, in recent decades their way of life has been dramatically altered and the magnificent jungle on which they depend for their physical, spiritual and cultural lives has been terribly exploited. This article examines the historical, current and future abuse of the Amazon rainforest, often called the lung of the world, in Ecuador by oil companies, and subsequent effects such as biodiversity loss and health consequences. In 1964, Texaco discovered that below the surface of the jungle floor in the northern region of the Ecuadorian Amazon, known as Oriente, lies reserves of crude oil and natural gas. As this was the first time anyone had successfully drilled for oil in the Amazon rainforest, the government of Ecuador, as well as the indigenous population, did not know what to expect from this discovery, nor anticipated the dreadful externalities that would result from this. Therefore, according to ChevronToxico, the Ecuadorian government and people “entrusted Texaco, a well-known American company with more than half a century of experience, to use modern petroleum practices and technologies in the emerging oil sector of the country.” Regardless of existing environmental laws, Texaco took advantage of the Ecuadorian government's ignorance and lax attitude and knowingly used reckless tactics that had been banned in the United States decades earlier. They deliberately used the cheapest technologies to preserve Yasuni, which amounted to $3.6 billion, according to Amazon Watch. President Correa said: “This is not the charity we were looking for [from the international community]. It was about a shared responsibility in the fight against climate change,” as noted in a National Geographic article. Unfortunately, the opportunity to “welcome a historic approach to freeing industrial society from its dependence on fossil fuels” failed and there were not enough funds to prevent the Ecuadorian government from abandoning the project. Action must be taken immediately because this greed has no end. What happened in the East has happened in many other regions and will happen in Yasuni. These oil companies are gradually choking the lungs of the world, and if this continues, the consequences will be even worse in the future. Eventually the Earth will stop breathing.
