Polymers of Our Progress


On this auspicious occasion of World Environment Day, let’s take a moment to delve in one of the strangest “Evolutionary” headlines you could imagine.

Breaking News! Slowly yet surely, humans have become the only animals who have shown the signs of digesting plastic without any side effects? Apparently, the new generation Beta, has begun adapting to the amount of plastic we consume, and slowly, maybe a few years later, our descendants will be able to digest it completely and make it biodegradable. Ironically, the ones who were contaminating the food chain, will now fix it. This ‘discovery’ has brought relief to countless plastic producers and recyclers.


Did you believe it? If you fell for it, welcome to the club. As plastic disposal remains an unsolved burning issue and masses are worried about the undisposable nature of this wretched material, despite the fact that none are actually concerned. People want a magical solution for its disposal. Moreover, microplastic is an even larger, yet oddly obscure, issue quietly bide their time to wreak havoc on our lives.


From food to fashion, from industry to medication. Microplastic has a wide reach. And wherever it reaches, it acts like a horcrux of plastic, making it immortal.


But what is microplastic? One widely accepted definition describes it as any plastic fragment between 1 nanometer and 5 millimeters in width. One nanometer is just a fraction of the width of a human hair, and 5 millimeters is about the width of a wedding ring.


Globally, an estimated 11 million tonnes of plastic waste leak into aquatic ecosystems each year, while microplastics accumulate in the soil from sewage and landfills due to the use of plastics in agricultural products. According to the UN Environment Programme, one estimate indicated that 2.7 million tonnes of microplastics seeped into the environment in 2020. This estimate is expected to double by 2040.


But what's the deal with microplastic today? On the occasion of World Environment Day, the spotlight turns to microplastic, on the theme of "Beat Plastic Pollution", a crisis whose reach has become dangerously widespread. Research says, from soil to air, from the rivers to the human blood, and from Mount Everest to the Mariana Trench. Microplastic has contaminated everything. And the worst part is it's affecting if it gets majorly accumulated. The leaching microplastic into oceans contaminates the aquatic life, which later contaminates food which humans and other organisms consume.


"As you sow, so shall you reap." A simple principle of Mother Nature. Easy to understand, easy to forget, but ruthlessly real.


But then what's the solution to this Microplastic dilemma? It would've been a magical solution if humans would've miraculously begun digesting plastic and rendering it biodegradable. But that’s just wishful thinking.


Nevertheless, the best possible solution can be rethinking a sustainable path with the help of a circular economy for plastic, meaning we need to rethink how we design, make, use and reuse plastics. Products must be designed to be used more than once, and to be recycled at the end of their life. This shift must involve everyone in the plastics value chain. A just transition is key to safeguarding waste pickers’ livelihoods and ensuring social fairness, leaving no one behind.

जागतिक नदी दिवस: एक पाऊल नदी संवर्धनाच्या दिशेने

सप्टेंबर महिन्यातील शेवटचा रविवार हा 'जागतिक नदी दिवस' म्हणून साजरा केला जातो. महत्वाचे म्हणजे आपल्या देशात अनेक नद्यांचे वाढदिवस देखील साजरे केले जातात.  जागतिक नदी दिवस साजरा करण्याचा प्रस्ताव देणारे मार्क अँजेलो यांनी ब्रिटिश कोलंबिया मधल्या अनेक नद्या स्वच्छ केल्या. ते नेहमी म्हणायचे की "कोणतीही नदी वाचवण्याच्या पलीकडे गेलेली नाही" त्यांचं हे वाक्य आजही महत्वाचे वाटते.

नदी ही देशाच्या शाश्वत विकासाच्या दृष्टिकोनातून महत्वाची भूमिका बजावत असते. माणसाच्या अनेक महत्वाच्या दैनंदिन गरजा ह्या बहुधा नदीवर देखील अवलंबून असतात. प्रत्येक सजीव प्राण्यासाठी पाणी अत्यंत महत्वाचे आहे, त्यामुळे पाण्याला  जीवन म्हटलं जात. भारत देशात 100 हुन अधिक मुख्य नद्या तसेच त्याहून अधिक उपनद्या आहेत. जगातील कतार, युएई, मालदीव, बहरीन, कुवेत ह्या देशांमध्ये नदी वाहत नाही. परंतु भारतात अनेक नद्या आहेत व या नद्या फक्त आपल्याला पिण्यासाठीच पाणी देत नाहीत, तर पिकांनाही त्यांच्या द्वारे पाणी दिले जाते. राज्यातील भीमा, मिठी, मुळा, मुठा, पवना,गोदावरी अश्या एकूण 53 नद्या ह्या प्रदूषित झाल्याचे प्रदूषित मंडळाच्या अहवालात दिले आले आहे. मुख्यता हे प्रदूषण रोखण्यासाठी हरित लवादाने दिलेल्या निर्देशानुसार राज्य सरकारने 2018 मध्ये नदी पुनरुज्जीवन समिती स्थापन केली आहे व या समितीमार्फत राज्यातील प्रदूषित नद्यांचा कृती आराखडा तयार करून केंद्रीय प्रदूषण नियंत्रण मंडळाकडे सादर करण्यात आले आहे.

देशातील अनेक महत्वाच्या नाद्यांसोबत अनेक महत्वाच्या गोष्टी देखील जोडल्या गेल्या आहेत, त्यामुळे नदीचे पुरातन काळापासून मानवी जीवनाशी व संपूर्ण सजीव सृष्टीशी एक महत्वाचे नाते जोडले गेले आहे. आपण आत्तापर्यंत असे ऐकले आहे की भारतातील अनेक नद्या एकाच दिशेने वाहतात म्हणजेच पश्चिमेकडून पूर्वेकडे. आणि बहुतांश नड्यांचा प्रवाह हा पश्चिमेकडून पूर्वेकडेच असतो परंतु आपल्या देशातील नर्मदा ही नदी पश्चिमेकडून पूर्वेकडे वाहत नाही तर ती पूर्वेकडून पश्चिमेकडे वाहते.

एकंदरीत भारतातील व जगातील अनेक नाद्यांचा विविध पद्धतीचा इतिहास आहे. नदी जगली तर गाव जगेल असं म्हटलं जात त्यामुळे नदी जगवण्यासाठी आपण प्रत्येकाने प्रयत्न करणे महत्वाचे आहे. आजच्या ह्या जागतिक नदी दिवसाच्या निमित्ताने आपण प्रत्येकाने नदी संवर्धनाच्या दिशेने पाऊल उचलूया.

The UAE's Encounter with Extreme Weather and Climate Change

The United Arab Emirates has been hit by heavy thunderstorms, resulting in the heaviest rainfall ever recorded within hours. This downpour flooded major highways, Dubai's international airport, homes, and malls. Operations at the airport were briefly halted. In Oman, at least 18 people lost their lives due to the storms. The rainfall, ranging from 127mm to 254mm in different parts of the UAE within 24 hours, has been described as a "historic weather event" surpassing records since 1949. Dubai faces severe flooding, with the amount of rain received in a single day equaling what typically falls over 1.5 years. Experts attribute this extreme weather to a normal weather system intensified by climate change, rather than just a cloud-seeding experiment. Cloud seeding is a process in which chemicals are implanted into clouds to increase rainfall in an environment where water scarcity is a concern. The UAE, located in one of the hottest and driest regions on earth, has been leading the effort to seed clouds and increase precipitation. A low-pressure system in the upper atmosphere, coupled with low pressure at the surface had acted like a pressure 'squeeze' on the air.

Scientists say that the intense weather changed into because of an extraordinary conjunction of climate systems bringing moisture from the Gulf, Arabian Sea, and Mediterranean. The flooding prompted chaos in a metropolis unaccustomed and unprepared for such conditions. Major avenue tunnels packed with water, bring transportation to a standstill. Water poured into purchasing department shops, residential regions, and construction websites. Due to the saturation of water on the roads, many cars have been damaged totally. They also lost their business of oil extraction and tourism during the period, which is a major source of revenue for the country. UAE has announced $544mn (2bn dirhams) for repairing homes. They also exempted people from various fines that were levied during this period, ranging from various traffic violation fines to fines for staying in the country after the visa period was over, as people had to wait in UAE as the aviation services had to be temporarily closed down.

Fortunately, the UAE's sturdy infrastructure and emergency planning prevented any catastrophic harm or lack of existence. However, the economic toll from the floods is predicted to be giant, with initial estimates in the billions of dirhams from businesses being closed down and belongings harm. Climate scientists caution that the UAE wishes to put together extra extreme weather activities like this in the future because of weather exchange. While the desolate tract place may absolutely become even hotter and drier on average, extended evaporation can also lead to extra excessive rain storms when conditions are right. The Dubai floods had been a stark reminder that even towns with terrific engineering prowess may be brought to their knees by effective herbal forces. As the arena continues warming, no nook of the globe might be immune to capability climate disruptions.
