Anthropogenic climate change served as a primary driver behind last month's catastrophic glacial mountain collapse along the China-Nepal frontier, a disaster that claimed upwards of 1,400 lives and left at least 6,600 individuals unaccounted for, researchers announced on Thursday.

A marine scientist has successfully unraveled a biological puzzle four decades in the making following the verified identification of an elusive new seaweed species originating from ancient British maerl beds. The initial encounter occurred during the 1980s when Professor Christine Maggs came across the minute, pink-striped organism while conducting doctoral research on maerl habitats—complex marine ecosystems constructed from calcified, coral-like seaweed fragments that support diverse aquatic life.  Collected Photo Suspecting the specimen was entirely unknown to science, Maggs embarked on a multi-decade quest to gather sufficient material to make a definitive identification. Collected Photo Throughout the intervening years, traces of the organism surfaced only sporadically, never yielding a substantial enough sample for conclusive laboratory study. The turning point arrived two years ago during a Natural England habitat monitoring dive off the Cornish coastline, where researchers retrieved a specimen resembling the long-sought marine plant.

Collected Photo To perform necessary genetic testing on the microscopic sample, Maggs cultivated the organism inside a temperature-controlled wine refrigerator, utilizing its dark, chilled environment to nurture growth prior to DNA extraction. Collected Photo "I just kept hoping that one day I would find out. It's been more than four decades," Maggs stated in an interview, emphasizing that obtaining genetic data was indispensable to resolving the mystery after forty years. Collected Photo Following successful DNA sequencing and official confirmation, a preserved specimen of the newly classified species has been formally deposited into the collections of the Natural History Museum. Describing the diving conditions within the maerl beds where spider crabs, starfish, king scallops, and goby fish thrive, scientific diver Lucy May noted, "It's magical. You feel completely surrounded by nature." Source: BBC

Today, July 28, is World Nature Conservation Day. This day is observed every year to highlight the importance of protecting the Earth's forests, rivers, water, soil, wildlife, and biodiversity. The day carries the message that a healthy environment is the foundation of human well-being and a sustainable future. However, on this day dedicated to nature conservation, concerns regarding the country's environment are mounting. Climate change, deforestation, river pollution, the plastic menace, and unplanned urbanization are continuously disrupting environmental balance, impacting human health, agriculture, economy, and biodiversity. According to media sources, the country's coastal mangrove forests are facing severe threats. In Cox's Bazar's Sonadia Island, embankments have been constructed along riverbanks, sluice gates installed, and arrangements made to retain saline water for tiger shrimp enclosures (ghers).  To build these enclosures, vast mangrove forests across the northern and southern parts of the island are being cleared.  In some areas, old trees have been cut down and cleared, while preparations to burn newly felled trees are underway in others. Satellite images and drone footage have also revealed widespread destruction of this forest. Environmentalists point out that mangrove forests are not only coastal landscapes but also act as natural shields against cyclones and storm surges. At the same time, they serve as safe habitats for numerous fish, crabs, shrimp, and wildlife. Destroying these forests will severely endanger both coastal biodiversity and the environment. Media reports indicate that environmentalists are also deeply concerned by an initiative to construct a waste transfer station inside Gazipur's Bhawal National Park. Experts fear that establishing such a facility in the middle of a protected Sal forest could pose a major threat to the environment and wildlife. In an interview with media, M.K.M. Iqbal Hossain Chowdhury, Divisional Forest Officer for the Bhawal Wildlife Management and Nature Conservation Department, stated that regular dumping of industrial waste, medical waste, household garbage, plastic, and other hazardous materials would severely pollute the air, soil, and environment. Spanning nearly 5,000 hectares of Sal forest, Bhawal National Park is an important habitat for deer, wild boars, mongooses, and various species of birds and reptiles. At the same time, this forest plays a vital role in carbon sequestration, protecting groundwater levels, and maintaining environmental balance around Dhaka. However, deforestation is raising concerns not just in Bhawal, but across various regions of the country. To conserve nature, experts recommend cultivating a few simple habits, such as planting and caring for trees regularly, reducing plastic use, preventing electricity and water waste, walking or cycling for short distances, avoiding throwing waste into rivers, canals, and water bodies, protecting wildlife, and teaching children to be environmentally conscious from an early age. According to experts, protecting nature is not solely the responsibility of governments or environmental organizations; it is the duty of every citizen. Planting trees, reducing plastic use, preventing the waste of electricity and water, keeping rivers and canals clean, protecting wildlife, and raising environmental awareness among children from an early age can play a significant role in nature conservation. Experts emphasize that protecting nature means gifting a safe world to future generations. Therefore, rather than just observing a single day, small daily conscious efforts can become the greatest strength in nature conservation.

The Bangladesh Meteorological Department (BMD) on Friday forecast heavy to very heavy rainfall across parts of the country over the next 24 hours, issuing a warning that the persistent downpours could trigger landslides in the hilly areas of the Chattogram division alongside causing temporary waterlogging within the metropolitan regions of Dhaka and Chattogram.  In a heavy rainfall warning issued in the morning, the agency stated that the precipitation is expected to impact areas within the Rangpur, Rajshahi, Mymensingh, Dhaka, Khulna, Barishal, Chattogram and Sylhet divisions during the 24-hour period commencing at 10: am on Friday, driven by the influence of an active monsoon.  Read More 5 Rivers Flow above Danger Mark amid Incessant Rains: FFWC According to the BMD, heavy rainfall is categorized as precipitation measuring between 44 mm and 88 mm, whereas very heavy rainfall denotes accumulation exceeding 88 mm within the designated forecast duration.  The nation's highest rainfall over the preceding 24 hours leading up to 6 am on Friday was recorded in Chattogram at 211 mm.  Meanwhile, day and night temperatures are expected to remain nearly unchanged across the country. Meteorological analysis shows that the monsoon trough extends through Punjab, Haryana, the center of the low-pressure area, Bihar, West Bengal, and Assam, running directly across central Bangladesh, with an associated trough stretching toward the North Bay.  The BMD further noted that the monsoon remains active over Bangladesh and strong over the North Bay.

Water levels in five rivers across the country are currently flowing above the danger mark due to persistent heavy rainfall both domestically and in upstream regions, according to the Flood Forecasting and Warning Centre (FFWC). Data released in a special flood forecast by the FFWC, measured as of 9 am on Friday, indicates that the Sangu River is running 95 cm above danger level at the Bandarban point and 23 cm above the threshold at the Dohazari point in Chattogram.  Meanwhile, the Matamuhuri River is flowing 47 cm above the danger mark at the Lama point in Bandarban alongside 32 cm above at the Chiringa point in Cox's Bazar.  In the northeastern region, the Kushiyara River is recorded at 18 cm above danger level at the Markuli point in Sunamganj and 10 cm above at the Fenchuganj point in Sylhet.  Read More UN Weather Agency Urges Global Preparedness as Strong El Nino Looms Furthermore, the Manu River is swelling 35 cm above the danger limit at the Manu Rail Bridge in Moulvibazar and 80 cm above at the Moulvibazar point itself, while the Khowai River registers 60 cm above the danger mark at the Balla point in Habiganj, the FFWC noted. Beyond the rivers surpassing critical thresholds, the FFWC reported that water levels at several other monitoring stations remain dangerously high and are currently flowing within the alert limit near the danger mark.  These vulnerable stations encompass the Teesta River at Dalia in Nilphamari, Kaunia in Lalmonirhat, and Tarapur in Gaibandha; the Kushiyara River at Sherpur in Moulvibazar; the Surma River at Kanaighat and Sylhet, as well as Chhatak and Sunamganj; the Someshwari River at Kalmakanda in Netrakona; and the Choto Feni River at Companiganj in Noakhali.
