Population growth and development patterns have a significant impact on the environmental performance.The issue of concern is whether population growth or the consumption/production patterns are responsible for environmental deterioration.This paper is an attempt to capture the impact of technological development,affluence,and population on environmental performance index,while previous stuthes had captured the impact of these three factors on environment only through CO_2emissions.The analysis reveals that technological development and population size have a negative impact on environmental performance,whereas measures to improve affluence have a positive impact.Technological development has increased the production of energy efficient products but at the same time consumption of these products has increased manifold leading to environmental deterioration.Demographic attributes need specific attention to improve environmental performance.This paper concludes on some policy reflections on slowing the population growth as well as persuades individuals and economies to relook to their consumption and production patterns and channelize their efforts to protect the environment. 展开更多

The escalating global population,environmental deterioration,and diminishing arable lands impose heightened demands on agricultural productivity,compelling the pursuit of more efficient breeding methodologies to enhance crop yield[1,2].As pivotal determinants of grain yield,grain size and weight have emerged as primary targets in crop breeding endeavors[3].In recent decades,extensive research has led to the identification of numerous genes and quantitative trait loci that regulate grain size in rice[4].Several genes have been shown to exert a positive regulatory influence on grain size and weight.For instance,upregulation of GL7/GW7 expression has been associated with the production of elongated grains,attributable to increased cell division longitudinally[5,6]. 展开更多
