- Blue whale is on the IUCN endangered list and has lost as much as 90 percent of its population in the last three generations
- The proportion of species that are threatened increases enormously as body size increases
- The mass extinction 65 million years ago that killed off the dinosaurs didn’t kill off bigger marine species at higher rates than smaller ones, unlike what’s happening now
Sept 16,2016: In the Earth’s oceans these days, the bigger a species is, the more prone it is to die off. That’s unheard of in the long history of mass extinctions, a new study finds.
As subfamilies of marine animal species — called genera — grow larger in body size, the likelihood of them being classified as threatened with extinction increases by an even greater amount, according to a study published Wednesday in the journal Science. In past extinctions, smaller creatures were more prone to die off, or size didn’t matter, said study lead author Jonathan Payne, a paleobiologist at Stanford University.
Almost none of the genera that have species averaging 0.4 inches (1 centimeter) long are threatened with extinction. However, 23 percent of those that are 3.9 inches (10 centimeters) are threatened, 40 percent of those that are 39 inches (1 meter) are endangered and 86 percent of those that are 32.8 feet (10 meters) are vulnerable, Payne said.

These are species that are not extinct yet, but are on the respected Red List of threatened and endangered species created by the International Union for the Conservation of Nature.
“The proportion of species that are threatened increases enormously as body size increases,” Payne said.
Take the blue whale, not only the largest living animal, stretching close to 100 feet long, but the largest to ever have existed, Payne said. It’s on the IUCN endangered list and has lost as much as 90 percent of its population in the last three generations, according to the IUCN.
On the other end of the spectrum is a grouping of fish, bioluminescent bristlemouths, that are about three inches long. They are the most abundant creatures with a backbone; the population is estimated to be in the trillions.
Focus on oceans
Payne compared fossil records, looked at past mass extinctions and compared them to current threats, concentrating on 264 genera that have the best modern and ancient records. Payne concentrated on oceans, where the fossil records are better over time. The mass extinction 65 million years ago that killed off the dinosaurs didn’t kill off bigger marine species at higher rates than smaller ones, unlike what’s happening now, Payne said.

The study “shows us how unusual this crisis of biodiversity we have right now,” said Boris Worm, a top marine scientist at Dalhousie University in Canada. He wasn’t part of the study but praised it. “We have had mass extinctions before. This one is totally different than what has happened before.”
Worm spoke from a break during research in Canada’s Bay of Fundy, where after a more-than-20-year career he finally saw his first underwater right whale and basking shark.
“They are both in trouble and both among the largest of their kind,” Worm said.
Payne’s study didn’t try to explain why larger animals were more threatened, but both he and Worm point to one main suspect: humans. Mostly through fishing and hunting, but also through environmental degradation such as warmer and more acidic oceans, humans have made it tougher for the biggest marine animals to survive, they said.
Catherine Novelli, the U.S. undersecretary of state for environment, said a world oceans conference that starts Thursday in Washington, will see the announcement of “many more” areas where nations set aside large areas of the seas where animals are protected and fishing is prohibited.
Duke University biologist Stuart Pimm also praised the study as both compelling and disturbing because “even if some species do hang on, we have massively changed the ecology of much of the oceans.”

Payne said there is still hope, since these species haven’t gone extinct yet. He points to northern elephant seals which had a population below 100 in the early 1910s, but are now more than 100,000 strong. But they are the exception.
“It pains you to the core to know that these animals might be gone in a generation or two,” Worm said. “You can’t imagine a world without them. It’s such an important and beautiful part of our planet.” (VOA)
Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India will set up a 50 megawatt (MW) solar power plant in Odisha's Sambalpur at a total cost of Rs 301.92 crore, moving steadily towards its goal to achieve carbon neutrality by 2024. MCL has placed a turnkey order to set-up a 50 MW solar power plant with a Chennai-based firm M/s Hild Energy Ltd, which will establish this green energy project within a timeline of 10 months, the MCL said in a statement on Saturday.
This solar plant would cater to the captive power requirement of MCL. The Central PSU had successfully set-up a 2MW solar power plant in Sambalpur in 2014. The company said it has pledged a target of installing 182 MW of solar power by 2024 in order to become a net zero energy company, aligning itself to use cleaner forms of energy for coal production.

This 50 MW solar power project will reduce CO2 emission by 91,020 tonnes per annum and carbon offsets of around 24,824 tonnes per annum, claimed the MCL. MCL is the leading production subsidiary of Coal India, having mining operations in Angul, Jharsuguda and Sundargarh districts of Odisha. Having achieved the highest ever capital expenditure of Rs 2,419 crore in the financial year 2020-21, the company has coal production and dispatch targets of 163 million tonnes and 182 million tonnes, respectively.
MCL was the coal mining company to introduce environment-friendly surface miner technology, which contributes over 95 per cent in coal production. As another environment-friendly initiative, the company has successfully introduced vertical rippers for blast-less over-burden removal in Hingula and Kaniha opencast projects. (IANS/ MBI)

As the nation celebrated the 114th birth anniversary of his father - renowned poet Harivansh Rai Bachchan - megastar Amitabh Bachchan remembered his dad as he penned a heartfelt note for him. The actor took to his blog where he poured his heart out and also shared an unseen photo with his father. The image in question is from Big B's wedding in 1973, where the two are caught in a sweet moment as they look at each other.
Amitabh Bachchan wrote on his blog,
"My Father , my all .. November 27th his birth in the year 1907 .. Which makes it his 114th Anniversary .. He is in the heavens, with my Mother and they celebrate .. as do we , in thought word and deed .. (sic). But first."
He then posted the picture followed by elaborate paragraphs. The megastar wrote,
"Those rare moments when one would find himself rushing against the winds to prevent the distance between us and to close it down as soon as it can be. The day of my wedding and his expression of fulfilment to not just be in congratulation but instead to be in the face of a belief, a chime, an ultimate season of love and great passion, of the quarries of the fears and conditionings of these deprived gym routines kart ..(sic)". "This could have been unknown for long facilitating years, to give not expected versions and lastly large scale informations of the insides ; but as time passed by, as does now , they explained purposely, the values of education and similarity .. Be in peace and love .. (sic)",
the veteran actor concluded his note. (IANS/ MBI)

The World Vegan month of November usually brings with itself an increased amount of dialogue and searches about Vegan lifestyle, sustainable living and clean beauty. Before pondering any further, it is important to understand what the Vegan lifestyle is and how it goes beyond the concept of consuming a plant-based diet. Veganism essentially is a lifestyle that is driven by compassionate choices and an increased awareness of one's actions on the world. Thus motivated by the two, a vegan individual usually carefully curates their day-to-day practices in a manner that does little to no- harm to the planet, the people and all of its inhabitants.
Beauty as industry has time and again been scrutinised for its effects on the consumers and the ecosystem - this can be during the manufacturing process or the effect it has on the consumer's thought processes. Now, as the world moves towards adopting Global Sustainability Goals, committing to a world that works with the natural resources instead of against them - it is only fair for each individual to be curious about making the right choices to make their beauty bag as consciously curated as possible. With multiple brands coming up with new standards of vegan and sustainable beauty, many consumers are left confused and doubting the authenticity of these claims. So here is a quick guide that can help you make the right choices:
Vegan and cruelty free labels: Keeping true to the traditional meaning of Vegan - any vegan beauty product means that it is completely plant based and has no animal ingredients or any of their by-products like honey, beeswax, dairy product etc. Similarly, cruelty-free as a label means that the ingredients or the final product did not test on animals or harm any animals during the production process. One way to test the authenticity is to check if these products are legally certified by PETA (People for the Ethical Treatment of Animals), or verified by Vegan organisations as The Vegan Society and others. Cruelty-free and vegan products are also generally categorized by having cleaner and gentler formulas as they are mostly deprived of harsh chemicals and solvents.

Ethical and natural ingredients: It is equally important to invest in products that use ethically sourced and sustainably harvested ingredients. Since most vegan products tend to be plant derived it is of utmost value to ensure that while the source is nature, the impact of manufacturing is also minimal so that there is no harm done to the environment. Often the face scrubs used by us are most damaging not just to the face and to the marine life as well; thus opting for more natural ingredients rather than synthetic ones is quite beneficial. Some natural scrubbing ingredients are sugar, salt, coffee which are safe for the coral reefs and far gentler than synthetic scrubs.

Sustainable and ecofriendly packaging: While the ingredients and formulation can be certified, it is also important to pay attention the quality, material and nature of the packaging in which the product is being stored. With an increase in clean-beauty standards, the consumption of such products has also increased, thus giving brands the opportunity to further develop their packaging in a manner that is sustainable and its increased quantity does not harm the environment. This could translate into using raw materials that are recycled and can be renewed or even introducing the concept of up-cycling the product packaging for decoration or storage purposes. Fore example, The Body Shop has recently launched a new line of vegan hair care and body butters; that are not only made of 95 per cent ingredients of natural origin but the packaging is made of recycled plastic that can further be recycled thus continuing the recycling system. Their makeup brushes also have wooden handles instead of plastic ones this adds to their classy appearance and use of ecofriendly material.

The above is a small snippet in a long list of things that can help contribute to a cleaner and more consciously lifestyle. Where demand increase, supply follows - as people begin to demand ethical, responsible production and products, more and more brands have begun to deliver. Household names such as The Body Shop have pioneered conversations on clean, green and sustainable beauty for decades - thus making them a frontrunner for several old time vegan people.
