Trillions of litres of water is consumed annually during colouration and other processes of textile manufacturing that includes 10–50 per cent toxic non-biodegradable petrochemical-based synthetic dyes being washed out in natural water bodies. The fashion industry also contributes 4 per cent of global greenhouse gas emissions. While modern synthetic dyes are highly efficient owing to their non-biodegradable nature, their accumulation in the environment is causing depletion of safe water and soil. Further, antimicrobial finishing of fabrics involves heavy metals such as copper, silver, and zinc that leach into the environment. Naturally occurring pigments from microbial sources have been used traditionally but were ignored by the fashion industry because of their inferior performance, restricted colour palette, and higher cost as compared to the synthetic dyes. However, with advances in regenerative agriculture, innovative extraction and cultivation techniques can be utilized to overcome these obstacles.

Enhancing Green Cover in HP
Not too long ago, a vast stretch of approximately ten acres of forest land in Parohi and Sangirthi of Bandladhar in the Bilaspur zone of Himachal Pradesh remained barren. The terrain was rocky, with minimal soil depth, making the idea of growing trees there seem implausible. However, today, this unproductive land is transforming into a verdant landscape, with 11,000 saplings of various tree species taking root. Sarita Brara informs that this transformation is attributed to the state government's Mukhya Mantri Van Vistaar Yojana (MMVVY), which aims to enhance green cover across thousands of hectares of barren forest land throughout the state. The MMVVY was officially introduced in 2023.
AI Writing, Illustration Emits Much Less Carbon than Humans
With the evolution of artificial intelligence (AI) comes discussion of the technology's environmental impact. A new study has found that for the tasks of writing and illustrating, AI emits hundreds of times less carbon than humans performing the same tasks. That does not mean, however, that AI can or should replace human writers and illustrators, the study's authors argue.
Celebrating 'Solar Sisterhood' Power

Surprising Role of Manganese In Soil Carbon Sequestration
A recent study reveals an unexpected link between manganese-a naturally occurring mineral-and increased carbon emissions from high-latitude boreal forests. The study uncovers how manganese increases carbon emissions from boreal forest soil, over time, challenging conventional understanding of the role of manganese in the carbon cycle.
India's Quest towards a Green Future With Green Initiatives and Climate Action
The interim budget of India for 2024-25 has placed significant emphasis on the green economy and investments aimed at combating climate change. These announcements are poised to reinforce India's prior endeavours in this direction. In this article, Sameeksha delves into concepts such as the green economy and climate action, highlighting that through its various initiatives, India has made significant progress towards the target of net zero emissions without compromising its economic development in less than a decade. These steps are expected to have a long-lasting impact, and the rapid growth of the country, coupled with green initiatives, will pave the way for a new era of prosperity.

Dr Krishna Kumari, Forestry Faculty, Pandit Deendayal Upadhyay College of Horticulture and Forestry, Dr Rajender Prasad Central Agricultural University, Bihar along with Supriya Rai, a third-year student pursuing BSc in Forestry at the same university, engage in a discussion regarding the objectives and benefits of the IFWCS.
Decreasing Emissions with Sustainable Practices
In this article, Sanjay Gupta highlights the significant role of the construction sector in global greenhouse gas emissions. The construction industry accounts for 19 per cent of greenhouse gas emissions. These emissions mainly result from energy consumption, material production, transportation, and the construction process itself. Nevertheless, there is optimism for the future, as technological advancements and increasing environmental awareness are driving the transition towards a more sustainable construction industry. Through the incorporation of innovative solutions, this sector has the potential to exert a strong influence on environmental consciousness. For the journey ahead, industry players should come together and unite in taking a collective responsibility against climate change to shape a world that is environmentally pure for generations to come.
