Ventura, California's 2023 winter storm activity underscored the impact that runoff has on recreational water quality and public health. To examine public perception of stormwater runoff, coastal water quality, and community decision-making toward recreating in polluted water, an online survey of the Ventura River watershed community determined…

Wildland fires have become a regular aspect of life for people living in the western United States. Wildfire smoke is now impacting air quality across the United States. Unprecedented wildfires have swept through Australia, Russia, and Portugal in the last few years. Like other natural disasters, wildland fires can have a devastating impact on…

The aim of this study was to investigation of the prospective science teachers' views on the problems (as are the waste of natural resources, the information pollution, sharing information without confirming their validity of information, communication problems among people, spending extra time and money, the laziness, the obesity, the…

Modifying the environment is a characteristic of the human species. With deforestation and the expansion of urban centers, diseases known in animals have begun to be described in humans. Science textbooks constitute an instrument of great importance in understanding this issue. This study evaluated the main science textbooks, recommended by the…

The environmental issues surrounding agrochemical products facing people today include serious health and ecological problems. Scientific literacy is necessary for students to understand scientific knowledge and get ready for the future world. Therefore, this action research aims to promote scientific literacy, in the area of plant growth by using…
