Luiz Cardoso da Costa was horrified as he watched the Amazonian manatee, a large docile beast, bleeding out from the knife wound he had dealt it, yet greedily gulping down grasses as if eating could somehow stave off death.
Activists opposed to the construction of the Belo Monte hydropower dam in the Amazon jungle say the Brazilian government's decision to boycott an Inter-American Commission on Human Rights hearing represents a "radical" shift in the country's foreign policy.
With victory cheers and predictions of future campaigns in defence of their ancestral territory, indigenous protesters from Bolivia's Amazon jungle region celebrated the new law that banned the construction of the road through their rainforest reserve.
The visual impact is harsh: flattened hills, valleys full of mud, and kilometres and kilometres of bulldozed land - the modification of nature in Brazil's semiarid Northeast region is disturbing due to the enormous dimensions involved.
The Suape port complex may be eternally absolved of its environmental sins for ushering in unprecedented prosperity in the impoverished northeastern Brazilian state of Pernambuco, and for having been built before stricter requirements were introduced.
Silvio Leimig was 18 years old and had just earned his driver's licence when he visited Suape, a port 40 km from his home in Recife, the capital of the state of Pernambuco in Brazil's Northeast region, in the early 1980s.
The development of one part of Brazil's semiarid Northeast, the Agreste region in the state of Pernambuco, could begin with the construction of canals that will bring in water diverted from the São Francisco River.
Bolivia's main trade union declared a 24-hour general strike Wednesday to protest Sunday's police crackdown on indigenous demonstrators who were protesting the construction of a road through a pristine rainforest preserve.
The steel and oil industries are still finding new frontiers for expansion. In Brazil's impoverished semiarid Northeast the key is not, like in China, cheap labour power or abundant raw materials, but logistical advantages.
Bananas are harvested where apples used to grow; cassava, a traditional crop, is disappearing from the Northeast; and the southeast is losing the fragrance of good coffee. This is the science fiction of a new distribution of crops in Brazil, South America's agricultural powerhouse.
Brazil is considered a country rich in water resources, with its enormous underground aquifers and mighty rivers. But recognition of the vital importance of rainwater begins where it is most scarce: in the semiarid interior of the northeast.
Violent clashes looked inevitable when some 1,500 desperately hungry peasants poured into this small Brazilian town. Riot police were staked out to prevent looting. It was the year 1993, and millions of people in Brazil's impoverished semiarid Northeast had been forced to the brink of starvation by three years of drought.
A richly biodiverse rainforest the size of 3,000 soccer fields in central Bolivia will be the first victim of the road planned to run through the Isiboro Sécure Indigenous Territory and National Park (TIPNIS), say environmental activists.
Raimundo Francisco Belmiro dos Santos, a defender of the Amazon jungle, has requested urgent protection from the authorities in Brazil after reporting that a number of hired gunmen are looking for him, because landowners in the northern state of Pará have offered a 50,000 dollar contract for his death.
The lack of regulations for consulting indigenous communities in Bolivia on initiatives that affect their territories is at the heart of a dispute over a road to facilitate traffic from Brazil, which would run through an enormous tropical national park self-governed by indigenous communities.
The port of Pecém in Brazil's impoverished Northeast region received a large order to unload and store cement factory equipment imported from China. The port authorities were unable to accept the original order, as the cargo would have occupied 40,000 square metres of storage space, nearly half the total available.
Biofuels are an alternative energy source that can drive local development by generating jobs, know-how and technology. But they can also cause social damage, as locals fear in the case of industrial-scale exploitation of babassu palm trees, which grow abundantly in the wild in central and northern Brazil.
Indigenous people in the eastern lowlands of Bolivia are again preparing to make the long march to La Paz, 21 years after their first such protest. They have vowed to make the trek in defence of their lands, which they say are threatened by plans for a highway to be built with the backing of the Brazilian government.
Despite challenges like high interest rates and high household electricity tariffs, the Brazilian economy has been growing at the highest rates seen in decades. Another problem that, although it has not stood in the way of growth, must be overcome is the costly use of roads for transporting farm products – an issue that is being addressed by the expansion of railway networks.
A bullet to his shoulder forced him to spend seven days in the hospital. In another attempt on his life, he was shot at three times, but miraculously escaped unscathed. "I will never sit next to a window again," says Brazilian rural activist Walter Moura.
Several rivers in the western Brazilian state of Mato Grosso are likely to become chains of artificial reservoirs feeding small hydroelectric plants (SHP), sometimes with larger power stations in between.
