Today severe cyclone Nivar will hit eastern coast of India. In 12 seconds learn how coastal green shelter belts check tsunami & cyclones. Dutch research institute Deltares.
We are facing one more #cyclone today. So let me remind you. #Mangroves;

- acts as buffer & reduce impact of cyclones & #storm surge.
- they break the #wind force
- provide #habitat to #animals during cyclone or otherwise
- they reduce #pollution.

We just need to protect them.
So how it works. Mangroves create a maze & dense habitat. With species which are salt tolerant & have special adaptations. They act like buffer & which slow down wind & consume energy. So after passing, the storms get dampen. You must have read in ‘Theory of Vibration’.
They are prop roots. In #mangrove #ecosystem they are adventitious support roots. They grow down from lateral branches, in a way support trees, with doing other root functions. Additionally roots buffer against damage to coasts & enhance biodiversity & carbon sequestration.
These are called as #pneumatophores. Mangrove ecosystem has high amount of soil moisture & salt. To take air trees here build special Aerial #roots. Which come out from ground & can grow upto 30 cm. Then air is supplied to all parts of a tree. #Natural filters.
Now as thick this #mangrove belt is, more effective it will be in resistance to #cyclones & other #disasters. Which is obvious also. They are not only shock absorbers but also provide habitat to numerous wildlife species which makes the system healthy & balanced.
#Mangrove #ecosystem is not static, like any other eco-system or system for that matter. It is dynamic, keeps changing. With size variety of #landscape increases. You see here in this pic a small #grassland inside mangrove belts. On one side destruction & another side creation.
Habitat to not only herbivores but also hypercarnivorous apex #predator like this. One of the largest crocodilian #species on #planet, whose size can go upto 6 metre in length. A salt water crocodile. This one basking in sun at Sunderban. A stable & balanced system.
Enough reasons to protect them says this deer. He wants you to share the message with others. They are also facing all these natural disasters.

All pictures & information are mine. During my exploration trips.
Thank you all for providing this thread such a reach. I hope few got the message also.

This is how yesterday female elephant from Dharmapuri, TN was rescued. Which fell in open well. After hours of operation, which included supplying food also, the elephant is rescued by forest team. It was a 50 feet deep well. And credits to the elephant also for her will. @ANI
Open wells & ditches in elephant migratory routes are huge problems for these animals. Since they are long ranging creatures, migrate to long distances for food & water.

Least we can do is cover such wells or keep safety wall. Imagine it was a 50 feet deep well.
It took a complete day for the forest staff to rescue the female elephant from 50 feet deep well. Every such rescue is a unique case where strategy is adopted based on circumstances.

Kudos to all involved in this one.

In 1930, anticipating the Nobel Prize, CV #Raman bought two tickets to Stockholm, other for his wife, as early as September, 3 months early.

His conviction was not misplaced; was decorated with the Nobel Prize for Physics that year for his path-breaking work. #BirthAnniversary
Raman was also the first Non white to get Nobel Prize in science. It took merely Rs.200 to make this discovery & now millions of rupees.

University of Cambridge offered him a Professor’s job.

He rejected & later appointed as 1st Indian Director of IISc Bangalore in 1933.
Later he wrote his experience of sitting under Union Jack while recieving the prize. How it led to his breakdown.

Amur falcons are back to India. Let me share story, a bird which crosses Himalayas enroute to India from Mongolia & Arabian Sea for going to Africa. This bird covers 22,000 KMs flying. One of the nature’s amazing wonder. In Nagaland they come in hundreds of thousands & stay. 1/n
While we were inside. Irang an Amur falcon was radio tagged by WII in Manipur. It went to South Africa, returned back to China. On October it again started journey. And in one year it covered 29,000 kms & back to Manipur. Which machine can beat that.
In one study three Amur falcons were radio tagged named as Naga, Pangati & Wokha. By 13 November they left Nagaland & by 25th December all three were in Southern Africa. With some halts in India. They took longest over water journey. Imagine the distance they covered flying.

During a significant project of DRDO, the work pressure was high. A scientist approached his boss – & asked to leave early that day considering he had promised his children to take them to an exhibition.

Boss generously granted permission, the scientist got back to work. 1/3
When he did, he lost the track of time & forgot to leave early. He reached home, feeling guilty, looked for his kids, but could only find his wife.

He asked for kids, and to his surprise she told him: “your manager was here around 5:15 and he took kids for exhibition!”. 2/3
Apparently, Boss had been observing the scientist and noticed that he might never realise he had to go home. Feeling for the kids, he decided to take the kids in his stead.

Boss was none other than APJ Abdul Kalam.

Remembering Kalam sir on his #BirthAnniversary 3/3
