The Pacaya Samiria National Reserve covers over 2 million hectares, making it the largest protected wetland area in Peru and one of the largest in the world.

The reserve is home to over 500 species of birds, including the iconic hoatzin, a prehistoric-looking bird also known as the "stinkbird" due to its unique digestive system.

Venture into the flooded forests during the wet season and you may spot the elusive giant river otter, one of the largest otters in the world, which can grow up to 1.8 meters long.

The Amazon is home to the highest diversity of freshwater fish in the world, with over 3,000 known species.

Many are yet to be discovered.

The trees in the Amazon act as massive carbon sinks, absorbing and storing vast amounts of atmospheric carbon dioxide, making the rainforest crucial in the fight against climate change.

Indigenous communities like the Kukama and Cocama have lived sustainably in the Amazon for thousands of years, using the river and forest resources while preserving the delicate ecosystem.

Scientists estimate that up to 30% of the oxygen we breathe is produced by the Amazon rainforest, earning it the nickname "the lungs of the planet."

The Amazon basin contains the largest river system in the world, with the Amazon River discharging 209,000 cubic meters of water per second, more than the next seven largest rivers combined.

Venture deep into the Pacaya Samiria and you may encounter the giant anaconda, the world's heaviest snake, capable of growing over 550 pounds and 550 cm in length.

Due to its remote location and difficult access, only around 1% of the Pacaya Samiria National Reserve has been explored by scientists, leaving vast areas of the rainforest ecosystem still unknown to the world.

Discovering the Remote Pacaya Samiria National Reserve: A Journey Through Peru's Amazon Rainforest - Challenges in Preserving the Amazon Rainforest Ecosystem


The Amazon rainforest produces 20% of the Earth's oxygen, but a recent study revealed that the Indian Amazon released nearly 20% more carbon dioxide in the past 10 years than it absorbed.

The Amazon rainforest is facing deforestation rates of approximately 17%, with human activities and climate change pushing the ecosystem to the edge.

Protecting the Amazon rainforest is crucial for maintaining Earth's delicate balance, as it is the world's largest river basin and tropical forest, and home to millions of unique plant and animal species.

The Amazon rainforest acts as a major carbon sink, regulating and helping stabilize the planet's climate.

Any loss or degradation of its forests means an increase in carbon emissions.

Innovative bioeconomy projects are being called for in the Amazon rainforest to protect and restore its biodiversity and ecosystem, as part of a global reforestation initiative aiming to conserve, restore, and grow one trillion trees by 2030.

The Amazon rainforest has been considered the "lungs of the planet," but this characterization is being reevaluated due to the recent carbon dioxide emissions data.

The Amazon rainforest's unique biodiversity plays a critical role in maintaining ecological stability for both local communities and people around the world.

Protecting the Amazon involves addressing both deforestation and degradation, as current levels of deforestation threaten the future resiliency of the Amazon's people and ecosystems.

The Amazon rainforest's trees have been absorbing carbon dioxide and producing oxygen, but human activities have led to a reduction in this process, with the Indian Amazon releasing more carbon dioxide than it absorbed in the past decade.

Deforestation due to agriculture, urbanization, and illegal logging is not only threatening the Amazon rainforest's unique species but also affecting humans worldwide, as the land ecosystems together absorb about 30% of the carbon dioxide released by burning fossil fuels.
