Cryptocurrency mining is a process that usually involves high energy consumption, due to the complex levels of computation required. In order to minimise the carbon footprint associated with the first digital currencies, alternative models with a low environmental impact have been developed: the so-called green cryptocurrencies.
Clean energy is energy in full development to fulfill our current desire to conserve the environment and deal with the non-renewable fuel crisis. With no pollution or waste, there are differences between clean and renewable energy sources, as we will explain later on.

Climate change is threatening food security all over the planet, and the same goes for water security. This concept can be defined as the capacity of a society to have enough adequate quality water available. It analyses the condition of surface water and subterranean aquifers and the use made of it with a territorial focus.
The carbon dioxide (CO2) emissions we release into the atmosphere not only worsen air quality, but also have an impact on the health of the oceans. Specifically, they cause a phenomenon known as acidification, which reduces the pH of the water, modifying its chemical composition and seriously affecting marine organisms. Solutions include reducing the use of fossil fuels in favour of renewable sources.

The paradigm shift in mobility, which advocates for electric vehicles that do not harm the environment, is driving the increasing spread of charging points. Thus, also known as electric charging stations are beginning to become an everyday reality in the landscape of cities and roads. Here we tell you how they work and the different types of charging they offer.
The sea ice is a floating ice sheet that forms in the polar ocean regions. The survival of, for example, polar bears depends primarily on the early formation of this icy surface, as it is here that they hunt. According to satellite observations that began in 1979, the average maximum extent of the Arctic during the months of March is decreasing decade by decade, confirming a worrying trend.

A study published in 2020 by the prestigious journal 'The Lancet' directly contradicted the forecasts being made by the United Nations (UN) about the future population of the world. At the time, the UN was predicting that there would be 11.2 billion people on the planet by the year 2100. 'The Lancet', meanwhile, reasoned that the global population would peak in 2060 and then fall to 8.8 billion by 2100 thanks to improvements in education for women and better access to contraception.
When we talk about endemism, we refer to a species whose geographical range is limited. Endemic animals and plants, whose vulnerability is enormous due to smaller populations, are key to their ecosystems and become a thermometer when it comes to measuring the state of health of a territory. For that reason, their protection from extinction threats is critical.
