Recent research has revealed that polar ice cabs are receding in the Actarctica and Greenland due to a global warming.
If the world’s largest carbon polluters don’t cut emissions more aggressively, Antarctic ice melt could speed up dramatically around the middle of this century, triggering “rapid and unstoppable” sea-level rise for hundreds of years to come.
All the ways are leading to KwaHlathi at Mnambithi in KwaZulu-Natal to pick up the stones which are thought to be a diamond.
Samples of the stones were taken by the teams of Mintek and GCS to be checked if they are diamond or not.
Premier of KwaZulu-Natal; Sihle Zikalala said that mining of any minerals without proper rights to do so is illegal.
He also mentioned that as many people are flocking in the area from all parts of South Africa to converge in one place, is contravening laws and regulations for Covid 19 as social distance protols are not practiced.
Law enforcement agencies are to placed in the area to monitor the situation.
“We all have the right to live, it’s either animal or human, then killing an animal for food consumption constitutes cruelty towards the living being,”
these are the words from the animal activists who against the killing of livestock for human consumption.
Scientists all over the world are obliging by coming up with a highly advanced solution to the so called ‘meat problem’. Lab-grown meat or cultured meat may be the future of meat and may negate the killing of animals and lead to a more sustainable and environmentlly friendly
Companies such as
1. Aleph Farms (Israel) : creates cultured steaks using proprietary 3-D technology. The process involves using a specially designed scaffold to coculture muscle, fat, and connective tissue, alongside vasculature to produce a fully formed steak within three to four weeks.
Aleph Farms claims its technologies allow several types of cells to grow together into a complex shape — which has historically been a major hurdle to developing structured meat products.
2. BlueNalu (San Diego):develops seafood products directly from fish cells using cellular aquaculture, whereby living cells are isolated from fish tissue, placed into culture media for proliferation, and then assembled into fresh and frozen seafood products.
3. Memphis Meats (California) : uses myosatellite cells to grow meat products, and has produced cultured chicken nuggets and beef meatballs, as well as duck tissue.
The company plans to produce a broad array of marine species, but is initially focusing on finfish including mahi-mahi, red snapper, tuna, and yellowtail. It recently demonstrated that its yellowtail product had the same culinary characteristics as conventional yellowtail, with the ability to be prepared in the raw or cooked form, including seared, grilled, and fried.
How is cultivated meat made?
The manufacturing process begins with acquiring and banking stem cells from an animal. These cells are then grown in bioreactors (known colloquially as cultivators) at high densities and volumes. Similar to what happens inside an animal’s body, the cells are fed an oxygen-rich cell culture medium made up of basic nutrients such as amino acids, glucose, vitamins, and inorganic salts, and supplemented with proteins and other growth factors.
Benefits of cultured meat
Lab-grown meat is more eco-friendly as compared to regular meat. It eliminates the need for livestock, which could reduce the use of energy by as much as 45%, reduce the use of land by 99%, and produce up to 96% fewer greenhouse gases. It will also be animal-friendly as no animals will be harmed or treated unethically.
Moreover, it will significantly reduce the amount of water usage, as the standard production of just half a kilo of meat requires around 9000 litres of water, as compared to 94 litres required for cultured meat. In regard to health, it is too soon to be able to determine any benefits from lab-grown meat, and only time will tell if it possesses any health benefits.
