“…GMOs, while a staple in conventional agriculture, remain controversial. A notable example is the widespread adoption of Bt cotton and its impact on human health, which several studies have generally found to have no direct negative health effects (Peshin et al, 2021).…”

With the world needing to feed an estimated 10 billion people by 2050, the paradigms of organic and conventional agriculture play a critical role in meeting these needs and ensuring environmental protection. This review critically examines these two agricultural paradigms by tracing their historical roots and exploring their techniques, impacts, economic considerations, and contributions to global food security. We highlight the environmental footprints with particular attention to soil health, water management, greenhouse gas emissions, and biodiversity. In addition, the health impacts of food produced in both systems and their societal implications will be discussed, with a closer look at aspects of consumer safety, community dynamics, and global market trends. By highlighting the strengths and challenges of both farming systems, this review argues for an integrative approach to agriculture that leverages best practices from both worlds. Such harmonization aims to create a sustainable future for agriculture that not only feeds humanity but also preserves the ecological balance on our planet.

“…Thus, studies have been conducted both in controlled laboratory conditions and in open field environments [14,50]. Tests of soil samples taken consecutively outside and inside Bt-cotton fields after three to six years of Bt planting indicated that three months after harvest the soil samples contained extremely low levels of Bt toxin, resulting in no detectable biological activities [50,51]. However, when the soils were sampled three months after the last season's tillage, which was conducted with shredders and disk plowings, most of the plant residues were found decayed.…”

Cotton (Gossypium spp. L.) is a major origin of natural fiber, and is projected at 117 million bales worldwide for 2021/22. A variety of biotic and abiotic stresses have considerable negative impacts on cotton. The significantly decreased applications of chemical insecticidal sprays in the agro-ecosystem have greatly affected the biodiversity and dynamics of primary and secondary insects. Various control measures were taken around the globe to increase production costs. Temperature, drought, and salinity, and biotic stresses such as bacteria, viruses, fungi, nematodes, insects, and mites cause substantial losses to cotton crops. Here, we summarize a number of biotic and abiotic stresses upsetting Bt cotton crop with present and future biotechnology solution strategies that include a refuge strategy, multi-gene pyramiding, the release of sterile insects, seed mixing, RNAi, CRISPR/Cas9, biotic signaling, and the use of bioagents. Surveillance of insect resistance, monitoring of grower compliance, and implementation of remedial actions can lead to the sustainable use of cotton across the globe.

“…The expression of insect-resistant proteins notably inhibits the growth of lepidopteran pests, such as cotton bollworm, reducing their impact on cotton and consequently increasing yield. Simultaneously, it curtails the use of chemical pesticides, alleviating environmental pressures [5][6][7][8].…”

Background Sudden temperature drops, resulting from extreme weather events, often occur during the boll-setting period of cotton in Xinjiang, China, causing decreased expression of Bacillus thuringiensis (Bt) insecticidal proteins in cotton bolls. The precise threshold temperatures and durations that lead to significant changes in Cry1Ac endotoxin levels under low temperatures remain unclear. To address this, we investigated the effects of different temperatures and stress durations on Cry1Ac endotoxin levels in cotton bolls. In 2020–2021, two Bt transgenic cotton cultivars, conventional Sikang1 and hybrid Sikang3, were selected as experimental materials. Various low temperatures (ranging from 16 to 20°C) with different durations (12h, 24h and 48h) were applied during the peak boll-setting period. Results As the temperature decreased, the Cry1Ac endotoxin content in the boll shell, fiber, and seed exhibited a declining trend. Moreover, the temperature causing a significant change in Cry1Ac endotoxin content increased with the prolonged duration of low-temperature stress. Among the components of cotton bolls, seeds were most affected by low-temperature stress, with the threshold temperature for a significant reduction in Cry1Ac endotoxin content ranging from 17°C to 19°C. Correlation analysis indicated that low temperatures led to a decrease in protein synthesis capacity and an increase in degradation ability, resulting in reduced Cry1Ac endotoxin content. Pathway analysis revealed that both amino acid and peptidase had significant negative effects on Cry1Ac endotoxin content. Conclusion In summary, when the daily average temperature was ≤ 19°C, implementing cultural practices to reduce free amino acid content and peptidase activity could serve as effective cold defense strategies for Bt cotton production.
