Microplastics in Sewage Become 'Hubs' for Drug-resistant Bacteria
As per a new study, ultra-fine plastic particles can become 'hubs' for antibiotic-resistant bacteria and pathogens to grow once they wash down household drains and enter wastewater treatment plants.
According to the scientists, including those from the New Jersey Institute of Technology (NJIT) in the U.S., these plastic particles less than five millimeters in length, called microplastics, allow the formation of a slimy layer, or biofilm, on their surface which allows bacteria and antibiotic waste to attach and mingle.
The research noted that certain strains of bacteria have elevated antibiotic resistance by up to 30 times when living on microplastic biofilms that form inside sludge units at municipal wastewater treatment plants.

NGT Panel Finds Damage to 30% Mangroves in Andhra's Kakinada
A joint committee constituted by the National Green Tribunal (NGT) to look into the cutting of mangrove forests in the coastal area of Kakinada in Andhra Pradesh's East Godavari district for a housing project, has confirmed destruction of nearly 30% of the mangrove area at the site. The committee also directed the district administration not to proceed with the township project and to take "remedial measures" for "rejuvenation of mangroves".
In its report submitted to the southern bench of the NGT, the committee observed that out of the total extent of mangroves spread over 116 acres, work has been taken up on 58 acres for "Navaratnaalu-Pedalanadirki Illu" (nine jewels-house sites for the poor) programme, thereby affecting mangroves in an extent of 30% of the filled-up area. The house sites' distribution programme was launched on December 25, but the preparatory work like identification of sites and levelling of sites began in March 2020.
The mangrove area also falls under Coastal Regulatory Zone-I area (CRZ-I), which is ecologically sensitive and the geomorphologic features of this zone play a role in the maintaining the integrity of the coast. As per CRZ notification 2011, no new construction shall be permitted in CRZ-I.

IIT Delhi to Build Atmospheric Observatory
The Indian Institute of Technology, Delhi (IIT-Delhi) announced that it is setting up an atmospheric observatory to do research, track atmospheric problems like air pollution, and suggest solutions to mitigate pollution, erratic monsoon and extreme weather events associated with climate change.
The observatory will be established in its research campus in Sonepat at a cost of Rs. 125 crore. The IIT said that Sonipat, which is located "upwind" of Delhi NCR, is an ideal location for measurements not only of the transport of dust and air pollution, but also various meteorological, radiation and cloud observations as these are key to understanding daily variations in weather and long-term climate changes.
This first of its kind observatory in the heart of the Indo-Gangetic belt will enable researchers to make new discoveries and help find sustainable solutions to some of the country's pressing problems such as severe air pollution, erratic monsoon and extreme weather events associated with climate change.

Campaign for Conservation of Butterflies in Rajasthan
Wildlife enthusiasts and environmental activists in Rajasthan have joined hands for a campaign for conservation of butterflies with a national appeal for care of the host plants to invite the insects with brightly coloured wings at home. The significance of butterflies in the pollination process was highlighted at an event held earlier this week.
Rajasthan gave 1,328th species to the country's list of butterflies last year with the discovery of Spialia zebra in Dungarpur district. The species flies at a high speed and is only 2.5 cm wide. It has been seen for the first time in India.

Global Energy Meet Calls for Accelerated Shift to Renewables
The COVID-19 crisis offers an unexpected opportunity for countries across the world to decouple their economies from fossil fuels and accelerate the shift to renewable energy sources, says the World Energy Transitions Outlook report, brought out by the International Renewable Energy Agency (IRENA).
Previewed at the virtual Berlin Energy Transition Dialogue (BETD 2021), the report proposes energy transition solutions for the narrow pathway available to contain the rise of temperature to 1.5 °C and halt global warming.
