With an unprecedented drought affecting Brazil, the consequences are being felt on the region’s aquatic life. In Lake Tefé, located in the state of Amazonas, an ecological tragedy is unfolding before our eyes. Since September 23, no fewer than 153 dolphins have been found dead, shedding harsh light on the harmful consequences of climate change in the region.
Research is currently underway to determine the exact causes of this massacre. However, several factors have already been highlighted. Drought, first of all, is a key element. Indeed, Lake Tefé is facing a significant drop in its water level, leading to a loss of habitat for dolphins who can no longer move freely. The latter thus find themselves trapped in increasingly restricted areas, with limited food, which makes them more vulnerable to disease and malnutrition.
Another possible cause of this tragedy is the El Nino phenomenon. The latter, amplified by climate change, contributes to increasing temperatures and decreasing precipitation in the region. These conditions favor the proliferation of bacteria and parasites, further weakening dolphins already weakened by drought.
Beyond this one-off phenomenon, this disaster highlights the long-term consequences of climate change on ecosystems and biodiversity. The Amazon, home to a rich diversity of endangered species, is particularly affected. The dolphins of Lake Tefé are an emblematic species of the region and their decline is a warning signal for the overall health of the ecosystem.
Faced with this tragedy, it is urgent to take measures to mitigate the effects of climate change and protect the fragile ecosystems of the Amazon region. It is essential to promote policies to preserve the environment, reduce greenhouse gas emissions and support local communities who depend on these ecosystems for their survival.
In conclusion, the historic drought hitting Lake Tefé in the Amazon has caused the death of many dolphins, highlighting the devastating consequences of climate change on biodiversity. This tragedy must serve as a reminder of the urgency of acting to preserve our planet and the species that depend on it.
