EVS Notes Unit 1 – 7
Unit 1: The multidisciplinary nature of environmental studies
“Environmental studies” is inherently multidisciplinary, drawing on various fields to understand the complex interactions between humans and the natural environment.
Unit 2: Natural Resources
“Natural resources” are materials and substances that occur naturally in the environment and are essential for human survival and economic development.
Unit 3: Ecosystems
An “ecosystem” is a dynamic community of living organisms, such as plants, animals, and microorganisms, interacting with each other and their physical environment, which includes elements like air, water, and soil.
Unit 4: Biodiversity and its conservation
“Biodiversity” refers to the variety of life on Earth, encompassing the diversity of species, genes, and ecosystems. The services ecosystems provide, such as clean air, water, and food.
Unit 5: Environmental Pollution
“Environmental pollution” is the contamination of the natural environment by harmful substances or activities, leading to adverse effects on ecosystems, human health, and the planet
Unit 6: Social Issues and the Environment
“Social issues and the environment” are closely linked, as environmental problems often have significant social impacts, particularly on vulnerable communities.
Unit 7: Human Population and the Environment
The relationship between “human population and the environment” is complex and increasingly critical as the global population exceeds 8 billion.
