Tropospheric ozone (O3) is a concerning pollutant, responsible for reduction in yields of major staple crops like rice, wheat, and maze. In this Journal of Environmental Sciences study, researchers from China and the United States of America found that rising O3 pollution led to national-level wheat, rice, and maize yield losses in China between 2005–2019. This trend was largely mitigated during COVID-19 lockdowns in 2020, indicating the need for an effective emission control policy.
Mining in Brazil does not deliver the sustained economic benefits often claimed, while informal mining is a major driver of deforestation, especially in the Amazon. A new study offers one of the most comprehensive assessments to date, combining satellite imagery and economic data to analyze the environmental and economic impacts of mining at the municipal scale across Brazil.
Canada can be a leader in health innovation if we support solutions that are developed within the health care environment, argues Dr. Muhammad Mamdani in a commentary published in CMAJ (Canadian Medical Association Journal).
