How Fungi Could Replace Concrete For Long Term Sustainable Hope

The challenging situation of global warming has been attributed to the increase in concrete jungles and the depletion in green covers across the globe. But this might just become a problem of the past, as fungi could be the solution to all the concretization issues of the world.
According to Ian Fletcher, senior professor of Architecture, Leeds Beckett University, fungi can actually be used to create a green construction industry. The actual construction material is derived from fungi. They are called mycelium composites. This material is created by growing mycelium – the thread-like main body of a fungus – of certain mushroom-producing fungi on agricultural wastes.
Current updates confirm that together, buildings and construction contributes to 39% of the world’s carbon footprint. Energy used to heat, cool and light buildings accounts for 28% of these emissions too. Amongst these, households are the biggest emitter of greenhouse gases since 2015, accounting for a quarter of total UK greenhouse gas emissions in 2017.
While the current corona virus outbreak has reduced the temporary carbon emissions and greenhouse gases, the use of alternate sustainable construction material will show long term benefits.
It is not so much as aviation fuel, but construction material that is responsible for the growing carbon emission levels in the world. According to Fletcher’s commendable research findings, Mycelium are mainly composed of a web of filaments called “hyphae”, which acts as a natural binder, growing to form huge networks called “mycelia”. These grow by digesting nutrients from agricultural waste while bonding to the surface of the waste material, acting as natural self-assembling glue. The entire process uses biological growth rather than expensive, energy intensive manufacturing processes.
A New York based architectural firm has already made use of organic mycelium. Another structure stands in Seoul Biennale of Architecture and Urbanism exhibition.  Adds Fletcher, “The development of mycelium materials from locally sourced agricultural waste could reduce the construction industry’s reliance on traditional materials, which could improve its carbon footprint. Mycelium composite manufacturing also has the potential to be a major driving force in developing new bio-industries in rural areas, generating sustainable economic growth while creating new jobs.”

Israeli settlers have once again attacked religious minorities in the region, this time targeting a church in East Jerusalem.

  According to reports, the settlers assaulted clerics and worshippers at the Church of the Sepulchre of Saint Charbel, causing damage to the property and injuring several people. This kind of behavior is not only unacceptable but also undermines efforts to promote peace and stability in the region. Attacks on religious minorities are a direct attack on religious freedom and must be condemned by all. The Israeli authorities must take swift action to bring the perpetrators to justice and hold them accountable for their actions. It is also important to ensure the safety and protection of religious minorities and their places of worship, as guaranteed by international law. this incident is a sad reminder of the ongoing conflict in the region and the need for a comprehensive and just solution. It is up to all of us to work together to promote understanding, tolerance, and respect for different beliefs and cultures, and to build a brighter and more peaceful future for all.

Fights break out as Kurds protest the French government's denial of a terrorist attack

  Following the murder of three Kurds in what is being considered to be a probable racist incident , there have been widespread protests in Paris. The fact that the authorities did not view the attack at a Kurdish centre as a terrorist act has enraged the Kurdish diaspora in Paris. A 69-year-old man opened fire on a crowd of individuals early on Friday morning at the Ahmet-Kaya centre on Rue d'Enghien in the 10th arrondissement. One of the three victims is badly injured. All of the dead were Kurdish community members who passed away both inside and outside the cultural centre. Agit Polat, a spokesman for the Kurdish centre, charged that French officials "yet again failed to safeguard us... This is a terrorist attack in our eyes, according to the AFP news agency. In the afternoon, a number of protestors, largely from the Kurdish diaspora, got into a fight with the police outside the centre and in the streets close by, throwing rocks and torching trash cans. Police use...

Verbal spat between Joe Biden and Benjamin Netanyahu over Israel judicial overhaul

  The Prime Minister of Israel, Benjamin Netanyahu, turned down United States President Joe Biden’s suggestion that the Israeli government “walks away” from a plan to overhaul the country’s legal system. A verbal spat between the two close allies took place on Wednesday. The US President and Israeli Prime Minister exchanged a few words on judicial changes in Israel. On Tuesday, reporters asked Joe Biden about Israel’s judicial overhaul planned reforms. Biden reportedly said, “I hope he (Netanyahu) walks away from it.” He said that the Israeli government “cannot continue down this road” and urged compromise on this plan to overhaul the country’s legal system. Subsequently, the Israeli PM said that his country makes its own decisions. He reportedly said in a statement, “Israel is a sovereign country which makes its decisions by the will of its people and not based on pressures from abroad, including from the best of friends.” Netanyahu’s latest comments came a day after he de...
