A humans well-being and socioeconomic progress are deeply connected to the environment. Peoples livelihoods, businesses, industries, and biodiversity depend on a stable and healthy environment. Furthermore, air and water pollution, deforestation, and soil degradation are causing significant harm.
But its also taxing resources, raising the cost of living and contributing to a housing shortage for workers. Many tourists will spend a night or two in town before or after their cruise, some choosing an Airbnb over a room at one of the citys mostly humble hotels. The remoteness, Ushuaias biggest selling point, only makes the strain worse.
Urban planners should plant hedges—or a combination of trees with hedges—rather than just relying on roadside trees if they are most effectively to reduce pollution exposure from cars in near-road environments, according to a new study from the University of Surrey.
New research by George Mason University found that exposure to certain air pollutants is linked to increased emergency department (ED) visits for respiratory and cardiovascular diseases. The study is published in the journal Environment International. We estimated associations between twelve ambient air pollutants of both primary (e.g.
By disrupting normal societal activities such as driving, COVID-19 lockdowns afforded a unique opportunity to study their impacts on the environment.
