Earth Day 2022

On April 22 every year, we celebrate the anniversary of the birth of the modern environmental movement with Earth Day. Since the first Earth Day in 1970, this day has marked global collaboration and awareness of the need to fight for a cleaner and healthier Earth. It all began in 1962 when Rachel Carson’s Silent Spring hit the New York’s bestseller list selling over 500,000 copies in 24 countries. As public awareness and concerns were raised over the environment, and the links between pollution and public health were put in the spotlight, Earth Day 1970 would come to provide a voice to this emerging environmental awareness. Today, with over 190 engaged and committed countries and over 1 billion individuals involved, Earth Day has come a long way. Since the first Earth Day, important strides have been made worldwide including the signing of the historic Paris Agreement and the implementation of the UN Sustainable Development Goals, and Earth Day continues to grow every year.

This year, the theme is “Invest In Our Planet” with a focus on preserving and protecting our health, our families, and our livelihoods because a green future is a prosperous future. To help you engage with Earth Day and its values, Elsevier presents a curated list of publicly available journal articles and book chapters. At Elsevier, we support environmental awareness an the goal of achieving a sustainable and equitable future. Together, we must #InvestInOurPlanet.

Several studies have indicated that a global reduction in meat consumption is inevitable for sustainability and public health, despite the challenges inherent to changing eating habits. The purpose of this article is to pursue a stock-take of consumer behavior with regard to reducing meat consumption through a literature review using bibliometric analysis. The findings show the multidisciplinary nature of the field, which is in full development and with many knowledge gaps. Publications are concentrated in a few dominant journals and originated exclusively in developed countries.

We studied several sustainable alternative protein concentrates and a whey protein concentrate as reference, to determine their protein composition, digestibility and quality using the harmonized INFOGEST static protocol. The proteins concentrates were analyzed to determine their conversion factor, degree of hydrolysis, true ileal digestibility, in vitro digestible indispensable amino acid score (IVDIAAS) and total absorbable amino acids and total essential amino acids.

Background: Nearly 40% of the world's population is exposed daily to household air pollution. The relative impact of prenatal and postnatal household air pollution exposure on early childhood pneumonia, a leading cause of mortality, is unknown. Research Question: Are prenatal or postnatal household air pollution, or both, associated with pneumonia risk in the first year of life? Study Design and Methods: The Ghana Randomized Air Pollution and Health Study enrolled 1,414 nonsmoking, pregnant women before 24 weeks’ gestation with prospective follow-up to the child's age of 1 year.

Ethiopia has experienced rapid urbanization over the past three decades. Several cities expanded rapidly and many satellite towns sprung up around the major cities. The high rate of urbanization and urban growth resulted in high demand for urban land, mainly for industrial, commercial, and residential purposes. In order to meet the demand, an enormous amount of land has been made available for urban use, mainly through land conversion. However, we know very little about how efficiently cities use urban land.

Introduction: Air pollution may play an important role in the development of lung cancer in people who have never smoked, especially among East Asian women. The aim of this study was to compare cumulative ambient air pollution exposure between ever and never smokers with lung cancer. Methods: A consecutive case series of never and ever smokers with newly diagnosed lung cancer were compared regarding their sex, race, and outdoor and household air pollution exposure.

Aquaculture and animal rearing for meat has increased exceedingly to meet the demands of ever-increasing population. Utilizing small fishes and agricultural products for feed production will lead to over exploitation of the resources and competition with food respectively. Microalgae can be next alternate source for animal and aquatic feed production in an environmentally sustainable and economically advantageous manner.

Background: With much of the world's population residing in urban areas, an understanding of air pollution exposures at the city level can inform mitigation approaches. Previous studies of global urban air pollution have not considered trends in air pollutant concentrations nor corresponding attributable mortality burdens. We aimed to estimate trends in fine particulate matter (PM2·5) concentrations and associated mortality for cities globally.

Background: Road-traffic injuries are a key cause of death and disability in low-income and middle-income countries, but the effect of city characteristics on road-traffic mortality is unknown in these countries. The aim of this study was to determine associations between city-level built environment factors and road-traffic mortality in large Latin American cities. Methods: We selected cities from Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Panama, and Peru; cities included in the analysis had a population of at least 100 000 people.

Background: Climate change and air pollution are two major societal problems. Their complex interplay calls for an advanced evaluation framework that can support decision making. Previous assessments have looked at the co-benefits of climate policies for air pollution, but few have optimised air pollution benefits. In our study, we lay out a modelling framework that internalises air pollution's economic impacts on human mortality, while considering climate constraints and aerosol feedback.
