Why do we need to curb our carbon emissions? Climatic changes due to anthropogenic carbon emissions have already increased the frequency of floods, wildfires, droughts and heatwaves around the world. The last report from the IPCC published in August 2021 reminded us that there is a near-linear relation between cumulative CO2 emissions and average global ...

Humans are currently facing a global triple-threat crisis. Together, population growth, climate change, and biodiversity loss paint a grim view of a future where agriculture has replaced wildlife, and humans and nature alike struggle for survival on a dying, overheated, overpopulated planet. Over the last few months, it has become clear that the magnitude of ...

In the last century, humans have so dramatically transformed the environment in which they live that the Earth has entered a new geological epoch: the Anthropocene. The magnitude, extent, and rate of change in the environment is so great that it is often hard to comprehend. The difficulty people have to realize how much ecosystems ...

Migratory birds undertake epic journeys connecting oceans and continents, awing people across the globe. Sadly, as spectacular as these seasonal movements are, many populations of migratory birds are in decline due to human threats, but tackling their conservation is challenging, as for most species many mysteries of their migrations remain unknown. Scientists believe birds migrate ...

The last decades, the implications of human actions in nature became more and more apparent. Exploitation of natural resources, habitat destruction in the sake of economic development, illegal species trading are only a few of the activities that have resulted in a new era of mass extinction, the Anthropocene. One of the responses to this ...

One year ago, the world stood still due to the Covid-19 pandemic, the virus spread inexorably, and most of the world was in lockdown. As a society, those were traumatic and confusing days. The uncertainties regarding what was happening and what was going to happen were immense. In this context, we tried to find positive ...

In his 93 years, the famous British naturalist David Attenborough has visited almost every place on earth, exploring the wild pristine nature, telling fascinating stories. “A life on our planet”, is his latest documentary, where he reflects on his life looking back at defining moments and the changes he has seen in nature and the ...

Bitcoin has been hailed as ‘the future of money.’ As I write this, a single bitcoin is worth over $34,000 USD. In 2009, when Bitcoin was released, a single bitcoin was worth $0.0008. That is less than one tenth of a cent. In between, billionaires have been made. Bitcoin’s incredible rise in value and popularity ...

Trophy hunting is a topic that sparks discussion, often debated in the comment section of a trophy picture shared on one of many social media platforms. A middle-aged man with a wide grin on his face, posing proudly with the corpse of a dead animal. Many find such images disturbing. I mean, who wouldn’t, right? ...

In May of this ‘exciting’ year of 2020, it was widely reported that the Smooth Handfish (Sympterichthys unipennis) was declared the first species of bony fish to go extinct in modern times. Without a doubt, it is sad that a creature described as having a ‘punk rock hair-do’ has been relegated to a single, discolored ...

Despite biodiversity conservation slowly creeping into national and international political agendas, monitoring and protecting all species remains impossible. We simply do not have the people, time or resources. So, at a time in which species are declining at unprecedented levels, which species should we focus on? Which species should concentrate all of our attention and ...

On a cold February day in Washington D.C. in 2015, United States Senator Jim Inhofe pulled an infamous political stunt on the senate floor. He unraveled a snowball that he had gathered earlier that day, using it as a prop to “disprove” the reality of climate change. He ended his statement by playfully hurling the ...

The moral debate surrounding the lethal control of invasive alien species Historically, humans have been translocating animal and plant species from one region to the planet to another, from seeds and exotic birds from the new world to rice and spices from Asian regions. Some of these translocations are well documented, like the introduction of ...

Since 1961, the average annual increase in global fish consumption has outpaced population growth and exceeded consumption of meat from all terrestrial animals combined 1. Accordingly, fish stocks have been increasingly exploited, with 33% of fish stocks overfished and 60% fully exploited in 2015 1. Demand for fish is driven by population growth, human migration ...

Despite some beliefs, climate change is real and humans are the ones to blame for. The increase of greenhouse gases – mainly CO2 – in the atmosphere, is the key driver of climate change. Emissions from human activities are responsible for 100% of the warming observed since 19501. One such activity is the production of ...

Birds undertake epic migrations across the globe. Knowing no borders, they connect many countries – and even the seas beyond national jurisdictions – in the search for safe heavens where to rest, refuel and spend the winter. But these are no easy journeys. Migratory birds face multiple threats and many populations across the world are ...

Underrate threat After habitat loss by agricultural expansion and logging, over-exploitation stands as the main threat for wildlife worldwide. The extraction of fauna from their natural habitats is known as defaunation, if done faster than natural populations can recover, it is known as over-exploitation. Defaunation can be divided into two categories: Subsistence hunting and commercial ...

Emergency to act! Recently, more than 11’000 scientists from 153 countries signed a paper in which they warn humanity that the planet earth is facing a climate emergency unless major transformations are made in global society (1). The scientists point out that the climate crisis is strongly linked to the excessive consumption of a wealthy ...

COP 25 is taking place right now in Madrid, and we can observe big corporations sponsoring all types of events. Among them is Endesa, an energy company responsible for 10% of the emissions in Spain1. Big corporations sponsoring environmental events is common, and more and more they are present in the environmental debates and the ...

Introduction The rate of resource use and its implication on environment has been well documented. According to the Living Planet Index report of 2018, 60% of wildlife population has declined over the last 40 years. It is also looking more and more likely that we will be unable to meet the goals we have set ...

Biodiversity is an abstract concept without a universally accepted definition (Meinard et al., 2019), with measures often incorporating both processes and entities. These may include: the functional diversity of a system, reflecting its biological complexity; phylogenetic diversity, whereby the distances between evolutionary lineages are summed; or species densities, relative abundances and total richness. Choosing an ...

THEIR habitats are among the most threatened ecosystems on the planet. And despite their critical value as a source of food and employment for hundreds of millions of people worldwide, it is likely that many freshwater fish species have already disappeared without record. Freshwaters cover just 0.8% of the Earth’s surface and hold 0.01% of ...

The high seas, or international waters, encompasses all areas beyond 200 nautical miles (nm) of shore, which in total constitutes one-half of the world’s surface area. Not only is this a massive area, but also hosts a diversity of life, with species ranging from sharks and albatrosses, to tuna and sea turtles using the high ...

Global biodiversity is being lost at an alarming rate. It is well-evidenced that this is the result of human activities, primarily agriculture and other forms of land conversion, as well as overexploitation of species. The World Wildlife Fund for Nature’s most recent Living Planet Report, published in November 2018, shows that surveyed animal populations have ...

Up to one million out of the roughly 8 million estimated species are threatened with extinction due to the impact of human activities, affirms the new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Compiled by 145 authors and with inputs from another 310 professionals, the IPBES Global Assessment Report on ...

The trade-off between environmental protection and human well-being is a longstanding issue in the realm of conservation. From forced evictions to unjustified restrictions of local resource use, conservation policies have often imperiled the most marginalized members of our societies. New research published earlier this month in Science Advances, however, suggests that this trend may be ...

Scientists in Sri Lanka have produced the first-ever evidence-based distribution map for Asian elephants. The researchers carried out interview surveys across the country and found that the charismatic mammals occur over around 60 per cent of the island nation, a much higher proportion than elsewhere in its 13-country range. Earlier distribution models either covered smaller ...

It was feared extinct for almost four decades. But a team of North American and Australian biologists has filmed Wallace’s giant bee (Megachile pluto) alive on a remote island in Indonesia. First discovered in 1859 by renowned English naturalist Alfred Russel Wallace, the thumb-sized species had not been seen since 1981, when American entomologist Adam ...
