Water covers two-thirds of the world, but only 1% of it is suitable for human use. On Earth, there are 326 million trillion gallons of water. The remaining 97 per cent is saltwater, which is unfit to drink. Freshwater makes up 2.5 per cent of the total, but most of it is locked in the poles or deep below. This leaves us with about 0.4 per cent to distribute among the 7 billion people on the planet.
This report discusses the rising market demand for lithium and the land reserves of lithium is going to be depleted by the end of 2080. That’s why there is a need to find some alternative. As rejected brine seawater contains a lot amount of lithium, there is a need to extract that lithium from the seawater. The process description and working of the electrochemical cell are explained in this report. A comparison of different techniques to extract lithium is also provided and the best possible techniques so far are discussed which was practically performed by the King Abdullah University of Science and Technology (KAUST) and some results of this experiment have also been shared.
The government guarantees issued official documents, and it effectively takes the role of the guarantor of the documents’ validity. However, traditional ID documents are not easy to use in a digital context, which brings us to acknowledge the importance of digital identity, which can fulfil the need for verifiable personal information while allowing users to bridge the gap between the online and the real world.
Climatic changes resulting from ominous human activities and excessive use of freshwater resources have adversely affected the quality and the quantity of the groundwater reserves. Access to potable water is getting limited globally, specifically across the Middle East and North Africa. Moreover, due to the presence of toxic pollutants freshwater shortage is also felt in Central and Western European countries and Latin America (Bundschuh et al., 2021). The population boom has exacerbated the water deficiency to a further dwindling level of below 1500 m3 per year (per person availability), which is far below the minimum essential standards.
Nowadays Circular Economy is mostly linked to anything, at the centre of many international debates, but what is it specifically?
Despite our actual Linear Economy, where production systems end with the disposal of dangerous waste, a Circular Economy aims to reduce most of the waste, converting it into an available resource that can be reused as secondary raw material in the production process. Every product or output, from the moment it is manufactured to the moment of its actual use, is optimized until the end of its life cycle. In this way, it is possible to recover and reuse all (or almost) the waste material as a starting point in another production chain.
4 weeks before COP26 in Glasgow. The belief that the world leaders will actually act has long vanished. But one thought comes up. Would it not be great if the climate crisis would be solved by an alliance of people, institutions and companies, that are willing to take actual steps toward a carbon-free economy and world?
The solutions are there. All! All over!
The fight against climate change does not depend on the availability of solutions, but on the willingness and political will to identify and implement new solutions.
The Conclusion
Only if people can gain financial benefit from reducing GHG emissions, will they start to effectively reduce their ecological footprint.
The components of the strategy to finally take the fight against climate change seriously are simple in themselves. However, that doesn’t mean that the world’s governments and stakeholders want to use them.
In this blog series, I asked people with specific expertise in their respective fields to write articles for me based on the questions I formulated. This resulted in short summaries and blog articles about what we have to understand as problematic in the area of climate, what we can expect from future climate development, what solutions there are in different areas and what we may have to do about it.
