Elephant extinction may raise carbon dioxide levels in atmosphere: Study

Washington D.C., Aug 3: Forest elephants engineer the ecosystem of the entire central African forest, but their catastrophic decline toward extinction has catastrophic implications for carbon policy.

One of the last remaining megaherbivores, forest elephants shape their environment by serving as seed dispersers and forest bulldozers as they eat over a hundred species of fruit, trample bushes, knock over trees and create trails and clearings. Their ecological impact also affects tree populations and carbon levels in the forest, researchers report, with significant implications for climate and conservation policies.

In a paper published in the journal of 'Nature Geoscience,' researchers found that elephant populations in central African forests encourage the growth of slow-growing trees with the high wood density that sequesters more carbon from the atmosphere than fast-growing species which are the preferred foods of elephants.

As forest elephants preferentially browse on the fast-growing species, they cause high levels of damage and mortality to these species compared to the slow-growing, high wood density species. The collapse of forest elephant populations will likely, therefore, causes an increase in the abundance of fast-growing tree species at the expense of slow-growing species, and reduce the ability of the forest to capture carbon.

Stephen Blake, one of the researchers of the study, spent 17 years in central Africa doing, among other things, applied for research and conservation work with elephants. While there, he collected a data set on forest structure and species composition in the Nouabale-Ndoki Forest of northern Congo.

In the current study, Blake's collaborators developed a mathematical computer model to answer the question 'What would happen to the composition of the forest over time with and without elephant browsing?'

To find out, they simulated elephant damage through browsing in the forest and assumed they browse certain plant species at different rates. Elephants prefer fast-growing species in more open spaces. As they feed and browse, they cause damage, knocking off a limb or breaking a shrub. The model calculated feeding and breakage rates along with elephant mortality rates to see their effect on certain woody plants.

"Lo and behold, as we look at numbers of elephants in a forest and we look at the composition of forest over time, we find that the proportion of trees with high-density wood is higher in forests with elephants," Blake said.

"The simulation found that the slow-growing plant species survive better when elephants are present. These species aren't eaten by elephants and, over time, the forest becomes dominated by these slow-growing species. Wood (lignin) has a carbon backbone, meaning it has a large number of carbon molecules in it. Slow growing high wood density species contain more carbon molecules per unit volume than fast-growing low wood density species. As the elephants "thin" the forest, they increase the number of slow-growing trees and the forest is capable of storing more carbon."

These findings suggested far-ranging ecological consequences of past and present extinction. The loss of elephants will seriously reduce the ability of the remaining forest to sequester carbon. Trees and plants use carbon dioxide during photosynthesis, removing it from the atmosphere. For this reason, plants are helpful in combating global warming and serve to store carbon emissions.

Without the forest elephants, less carbon dioxide will be taken out of the atmosphere. In monetary terms, forest elephants represent a carbon storage service of $43 billion.

"The sad reality is that humanity is doing its best to rid the planet of elephants as quickly as it can. Forest elephants are rapidly declining and facing extinction. From a climate perspective, all of their positive effect on carbon and their myriad other ecological roles as forest gardeners and engineers will be lost," Blake concluded.

May 28: Abdul Kareem was forced out of school and into a life of odd jobs like repairing bicycles before he finally managed to pull his family out of abject poverty transporting goods across Delhi in a mini truck.

The job, and the slim financial security that came with it, was the first stepping stone to a better life.

All that is now gone as India reels under the economic impact of its protracted coronavirus lockdown. Mr Kareem's out of a job and stranded in his village in Uttar Pradesh with his wife and two children. Their minuscule savings from his Rs 9,000 a month job have been exhausted, and the money he saved for books and school uniforms is spent.

"I don't know what the job situation will be in Delhi once we go back," Mr Kareem said. "We can't stay hungry so I will do whatever I find."

At least 49 million people across the world are expected to plunge into "extreme poverty" -- those living on less than $1.90 per day -- as a direct result of the pandemic's economic destruction and India leads that projection, with the World Bank estimating some 12 million of its citizens will be pushed to the very margins this year.

Some 122 million Indians were forced out of jobs last month alone, according to estimates from the Center for Monitoring Indian Economy, a private sector think tank. Daily wage workers and those employed by small businesses have taken the worst hit. These include hawkers, roadside vendors, workers employed in the construction industry and many who eke out a living by pushing handcarts and rickshaws.

For Prime Minister Narendra Modi, who came to power in 2014 promising to lift the poorest citizens out of poverty, the fallout from the lockdown brings with it significant political risk. He won an even larger second term majority last year on the strength of his government's popular social programs that directly targeted the poor, such as the provision of cooking gas cylinders, power and public housing. The breadth and depth of this renewed economic pain will only increase the pressure on his government as it works to steer the country's economy back on track.

"Much of the Indian government's efforts to mitigate poverty over the years could be negated in a matter of just a few months," said Ashwajit Singh, managing director of IPE Global, a development sector consultancy that advises several multinational aid agencies. Noting that he did not expect unemployment rates to improve this year, Singh said: "More people could die from hunger than the virus."

Desperate Times

Mr Singh points to a United Nations University study estimating 104 million Indians could fall below the World Bank-determined poverty line of $3.2 a day for lower-middle-income countries. This will take the proportion of people living in poverty from 60% -- or 812 million currently, to 68% or 920 million -- a situation last seen in the country more than a decade ago, he said.

A World Bank report found the country had been making significant progress and was close to losing its status as the country with the most poor citizens. The impact of PM Modi's lockdown risks reversing those gains.

The World Bank and the CMIE estimates were published in late April and early May respectively. Since then the situation has only become grimmer, with harrowing images of people making desperate attempts to reach their villages, on crowded buses, the flatbeds of trucks and even on foot or on bicycles dominating media coverage.

The Rustandy Center for Social Sector Innovation at the University of Chicago Booth School of Business analyzed the unemployment data from the CMIE, collected through surveys covering about 5,800 homes across 27 states in April.

Researchers found rural areas were the hardest hit, and the economic misery was the result of the lockdown, rather than the spread of infections in the hinterland. More than 80% of households had experienced a drop income and many won't survive much longer without aid, they wrote in a report.

The government has promised cheap credit to farmers, direct transfer of money to the poor and eased access to food security programs -- but these help people who have some documentation, which many of the poorest don't. With millions of impoverished people now in transit across the country, the food security situation is dire -- news reports are emerging of people foraging through piles of rotting fruit or eating leaves.

Shattered Economy

The economy was already growing at its slowest pace in over a decade when the virus struck. The lockdown, which came into effect on March 25, has hammered it, stalling business activity and putting a lid on consumption, pushing the economy to what may be its first full-year contraction in more than four decades.

It's dire enough to warrant the country exiting its lockdown, as it has been doing incrementally since May 4, even as its infections are surging. India is now Asia's virus hotspot with infections crossing 151,000 according to data from Johns Hopkins University.

PM Modi, who has come under criticism for the pain inflicted on the poor, has said his government will spend $265 billion or about 10% of its GDP to help Asia's third-largest economy weather the pandemic's fallout. But experts say only a part of it is direct fiscal stimulus, and probably smaller than the total damage done to the economy during the lockdown period.

"What is especially worrying is the government's response," said Reetika Khera, an economics professor at the Indian Institute of Technology in Delhi. "The epidemic will magnify existing -- and already high -- inequalities in India."

Still, the economic measures aren't going to kick in for some time and industry will likely struggle to restart because of the flight of labour from industrial hubs.

And as the harsh summer unfolds more pain lies in store in the villages now dealing with returning migrant workers.

"There are no factories or industries here, there are just hills," said Surendra Hadia Damor, who had walked nearly 100 km from Ahmedabad, Gujarat, before a voluntary organisation drove him to his village in the neighboring state of Rajasthan. "We can survive for a month or two and then try and find a job nearby -- we will see what happens."

New Delhi, Mar 15: Dozens of Hindu activists held a cow urine party in New Delhi on Saturday to protect themselves from the new coronavirus, as countries around the world struggle to control the deadly pandemic.

Members and supporters of the All India Hindu Mahasabha staged fire rituals and drank from earthen cups to fight the Covid-19 virus at the gathering in New Delhi dubbed a "gaumutra (cow urine) party".

"Whoever drinks cow urine will be cured and protected," Hari Shankar Kumar, a volunteer at the event, said as he served the remedy in brown clay cups.

Governments and scientists have said no medicine or vaccine is available to protect or cure people of the infection that has killed more than 5,400 people and infected nearly 150,000 across six continents.

Two people have died in India while more than 80 have fallen ill, and the government has ordered the closure of some land routes into the country and cancelled all visas to stop the spread of the virus in the world's second most populous country.

Members draped in saffron clothes chanted Hindu hymns at the fire ritual as devotees sang paeans for the sacred animal.

"We have gathered here and prayed for world peace and we will make an offering to the corona (virus) to calm it," Chakrapani Maharaj, the group's leader, told reporters before gulping down a cup of urine.

He then offered a glass to a devil-shaped caricature of the virus to "pacify" it.

He urged people to adopt the "tried and tested" practice of drinking cow urine to ward off diseases, and desist from killing animals and eating meat.

"The coronavirus is also a bacteria and cow urine is effective against all forms of bacteria that harm us," claimed Om Prakash, a participant from the neighbouring state of Uttar Pradesh.

One legislator from the BJP last week suggested use of the urine as well as cow dung can cure the coronavirus.

A Waste is a Waste.... God has created a system in our body and animals to throw out the excess wastage from our body... Guys please stay away from drinking the wastage and putting the wastage inside the body again . U will be a loser health wise and mentally. 

 

 

Cows will surely think by seeing these people that human beings are stupid to drink our wastage... Drink its milk which is beneficial drink that God has given us.

If your faith is scientific, simply go to Corona infected patients and cure it.

 

If you are successful, Not only India the whole world will be Hindus. 

 

If you cant, you will never do it with cow urine or any other urine. People will losse faith on your type of Hinduism.

New Delhi, Feb 16: Just an hour ahead of the swearing-in ceremony, Arvind Kejriwal invited the people of Delhi again for his oath-taking ceremony at Ramlila Maidan today.

Referring himself as "son of Delhi", the AAP convener today tweeted saying, "Delhiites, your son is going to take oath as Delhi chief minister for the third time. You must come to bless your son".

The AAP national convener will be sworn-in as the Chief Minister of Delhi for the third time in a row.

Arvind Kejriwal is scheduled to take oath along with other ministers at Ramlila Maidan.

On Saturday, Kejriwal, through a tweet, has said that autorickshaw drivers, students, teachers, doctors, labourers, etc will be the "chief guests".

The guest list put out by the AAP includes ''Delhi ke Nirmata''- people who contributed to the development of the city during the last five years.

These include Sumit Nagal, a Delhi government school student and an international Tennis player, Laxman Chaudhry an auto driver, Manu Gulati a teacher and "one of the many architects of Delhi Governance Model", Dalbir Singh a farmer, Ratan Jamshed Batliboi - the architect of the famous Signature Bridge among others.

By winning 62 seats by cashing in on the plank of development, his party nearly repeated its 2015 performance, sweeping the Assembly polls in the face of a high-voltage campaign by the BJP, which had fielded a battery of Union Ministers and Chief Ministers in its electioneering, spearheaded by Home Minister Amit Shah.

The BJP marginally improved its tally, managing just eight seats from its 2015''s tally of three seats. The Congress failed to open its account in the second successive election.
