🌏Today is #InternationalGeodiversityDay declared by UNESCO to recognise the importance of geosciences in solving the major challenges faced by humanity today.

So what does #geodiversity mean & how can #India better acknowledge & conserve its incredible #geoheritage?

Thread🧵 A creative with a quote defining geodiversity as the variety
At present, #India classifies #geodiversity in different ways.

Here are some broad categories that may serve us well:

Geo-monuments, #fossil sites, archaeological sites, and landscapes - we've listed many sites under the first 3 categories, yet we need to do SO much more. A creative showing 4 icons for the various categories of geo
Here's an example from Gandikota, #AndhraPradesh.

There is no interpretation sign/infrastructure at the incredible canyon carved by the Penna river & the archaeological ruins, nor at the Belum limestone caves nearby:



#InternationalGeodiversityDay
Here are some other examples of #geodiversity from across #India, with natural or cultural value - some recognised & some undervalued.

We build statues & talk of celebrating our past, yet there is a million-/billion-year history buried within our geoheritage sites...

Especially, if viewed through the lens of landscapes.

The Rann of Kutch tells stories of the ebb & flow of the Indus river & the civilization that flourished/floundered along it.

Laterite plateaus talk of how rain alters the hardest of volcanic surfaces into a pitted moonscape. A creative with a bold earthy swatch featuring the quote: I
#Geodiversity allows us to plumb stories at 3 different timescales: deep time, evolutionary time, and human history.

Every ~month, the #Geosophy newsletter tries to weave such stories about Earth & #India.

For years, Big Oil campaigned to convince the public that #climatechange isn't real.

So did Global FMCGs to push the onus of #plasticpollution onto individuals!

Citizen science efforts like the #BrandAudits2023 — in its 6th year — analyses data to identify the top polluters!
Ultimately, the individuals pays the price for environmental pollution of air, water, soil, which affects our health & well-being.

At what price convenience?

This data starkly shows just how much food packaging contributes to global #plasticpollution:

For those who say: if not plastic, what? There was a world order before everything was wrapped in plastic — within my lifetime and yours!

These corporations spent $$$ on R&D when scaling up #plastics, what's stopping them from investing in reuse & refill models at scale?

Travelling through #India you can't miss such boulder heaps...

Think of Hampi's ruins (below) or Sravanabelagola (Karnataka), or Mt Abu (Rajasthan)?

#DidYouKnow, such isolated hill/ridge features that jut out from the surrounding plains are called #inselbergs?

#Geo thread/ Geology: inselberg formation at Hampi, Karnataka, India
Derived from German words meaning 'island mountain', #inselbergs are residual features that form across climatic zones.

Yet are most abundant in tropical regions with granite-gneiss outcrops, like those on the cratons across India, as also in the zones marked BCG, CGC, and SGT. Map in the publication, The Indian Peninsula: Geomorphic Lan
Debates rage on how #inselbergs formed, yet most concede they are the result of weathering (breaking down of rocks at site) and erosion (transport of weathered material).

In #India, insolation (heat from sun's rays), rainwater, and rivers have shaped landscapes for millennia. Hampi's boulder inselbergs with the river Tungabhadra snakin
