Iceland opens world record carbon plant

Climeworks, a Switzerland-based company, has introduced its second commercial direct air capture (DAC) plant, dwarfing its predecessor Orca in size by a factor of ten. Orca, which commenced operations in 2021, served as the foundation for this leap in scale, as reported by CNN.

Direct air capture: Climeworks and Carbfix create a zero-waste process

Direct Air Capture (DAC) technology utilizes chemical reactions to extract carbon from the atmosphere. The resulting carbon can be repurposed for various applications, including underground storage or conversion into valuable products.

Climeworks intends to sequester the captured carbon underground, where it naturally transforms into rock, effectively storing the carbon indefinitely. This process, known as sequestration, is conducted in collaboration with the Icelandic company Carbfix. What sets this project apart is its reliance on Iceland’s clean geothermal energy to power the entire operation. As a result, the process of capturing carbon and converting it into stable stone occurs without emissions from the technology itself, thereby aiding in the reduction of carbon emissions.

Despite the potential of carbon removal technologies like DAC, they remain contentious due to significant challenges. Critics argue that they are costly, energy-intensive, and not yet proven at scale. Additionally, some advocates for climate action express concern that focusing on such technologies may divert attention from the urgent need to decrease dependence on fossil fuels.

Climeworks unveils Mammoth, a giant carbon capture plant

Climeworks has unveiled Mammoth, an enormous carbon capture facility. Construction of Mammoth commenced in June 2022, marking it as the largest facility of its kind globally. Its modular design accommodates 72 collection units dedicated to capturing carbon from the air. Presently, 12 of these units are operational, with plans to expand in the coming months.

According to Climeworks, Mammoth has the capacity to extract 36,000 tons of carbon annually from the atmosphere. This is equivalent to offsetting the emissions of approximately 7,800 gas-powered vehicles for a year. Mammoth represents a significant stride in mitigating the impact of carbon on the climate and underscores the potential of carbon capture technologies to address climate change on the requisite scale.

Mass extinction: more than 1,400 bird species lost to human activity

The world of wildlife around us is a different combination of different species of animals. Scientists have recently discovered how devastating the consequences of our actions can be. Birds and humans have a long history of coexistence, but unfortunately, many bird species have vanished because of human activity  intervention. Recent research by a team of scientists from Sweden and the UK, headed by Rob Cook, has used statistical models to determine the extent of this influence. They concluded that before the 1500s, human activity may have been responsible for the extinction of a significant number of bird species, as reported by New Humanist.

Tragedy on the islands: extinction of birds due to human activity

Recent scientific research led by Rob Cook of the UK’s Center for Ecology and Hydrology has highlighted how the islands have become a major focus of these tragedies. Using New Zealand as an example, where the scientific community has a complete record of pre-human bird species, the researchers made a number of educated guesses to arrive at the global death toll. The results were stunning: every eighth bird species became a victim of human activity. The total number of species lost was a dismal figure – about 1,400 species were destroyed due to our influence. This is alarming because birds play a key role in the balance of nature, from  pollinating plants to scattering seeds, and their disappearance severely disrupts ecosystems.

Although the past cannot be changed, the present situation for our feathered friends does not look much promising. In the UK alone, wild bird numbers have decreased by 73 million since  the 1970s. Simple measures such as installing bird feeders or limiting outdoor cats’ access to them can help, but more serious steps are needed to make real change. Restoring natural habitats, moving towards sustainable agricultural practices and efforts to combat climate  change are critical measures to give birds a chance to survive in the modern world.

This study doesn’t just describe the pain of loss in nature, it serves as a wake-up call for humanity. It highlights our significant impact on the planet and calls for greater conservation efforts. By understanding our past mistakes, we can move forward to a future where birds and people can continue to thrive together without hurting each other.

Endangered Birds: The Biodiversity Crisis and the Role of Human Impacts

Every year, many bird species disappear on Earth as a result of human activity and environmental changes. According to research, since the beginning of the 20th century, about 200 bird species have been declared extinct. Among them are such famous species as the giant dodo, passenger pigeon and pygmy islander deer giant dodo,lived on the island of Mauritius, and was one of the largest flying birds in the world. However, the arrival of European sailors in the 17th century led to the extinction of this visible and clumsy bird within just a few decades.

Passenger pigeon,once the most abundant bird species in North America, was driven to extinction in the early 20th century by commercial hunting and loss of natural habitats.

Islander dwarf deer,living on the islands of the Mediterranean Sea, also faced threats caused by human influence. Loss of natural habitats and hunting have led to the   disappearance of this distinctive bird species. Human activities, such as deforestation, pollution, the introduction of invasive species, and hunting, have emerged as the primary drivers behind the extinction of numerous bird species.Island species, whose natural habitats are being destroyed, are particularly vulnerable to these threats.

It is unfortunate that many of these extinct species were distinct and have no counterparts among current  bird species. Their loss not only means a loss of biodiversity, but also the potential loss of valuable information about the life and evolution of birds.

To preserve the remaining species and prevent further extinction of birds, it is necessary to take effective measures to protect nature, preserve and restore their habitats, and reduce human impact on the environment.
