Balancing economic growth with environmental protection is especially challenging for developing countries, even more so for those relying heavily on foreign aid. Recently, researchers from Japan developed a theoretical framework to show that zero-emissions policies can be compatible with sustainable growth in such nations. Their findings highlight the critical role of foreign aid, clean technologies, and effective tax policies in helping countries reach the minimum income threshold per person needed to effectively implement zero-emissions strategies.
Children from less-advantaged socio-economic circumstances have a significantly increased risk of developing asthma. Smoking during pregnancy and breastfeeding are two of the major contributing factors to these inequalities This is stated by a new European study led by the University of Copenhagen. The researchers call for the authorities to support families better.
The project aims to study the mental health of adolescents aged 14 to 17 living in Spain and to analyse which support networks are important at this stage. To do so, both qualitative and quantitative methodologies were combined, yielding several samples: a representative sample of 806 adolescents nationwide and an additional sample of 228 LGTBI+ adolescents for the survey and 44 LGTBQI+ participants in discussion groups.
The results show that 11.2% of adolescents in the overall sample report feeling very or quite unhappy, and 38.8% indicate that they have experienced loneliness regularly in the past year. Regarding depression, 14% would be experiencing severe episodes, and 6.6% would be in very severe episodes.
Additionally, the study finds that 15.7% of respondents report having attempted suicide, 19.8% have considered it, and 29.3% have engaged in self-harming behaviours in the past year, of which 10.5% report thinking about it frequently.
A new study, published in Nature Climate Change, offers a comprehensive picture of public attitudes toward climate policies, such as carbon taxes, in seven large countries in the Global South: Chile, Colombia, India, Kenya, Nigeria, South Africa, and Vietnam. The study highlights both the depth of climate knowledge in these countries and the trade-offs citizens face when weighing climate policies against other urgent needs.
