Study Notes
Introduction to Environmental Science
- Environmental science is an interdisciplinary field that examines the interactions between humans and the environment.
- It encompasses a wide range of topics, including pollution, resource depletion, biodiversity loss, and climate change.
- The field seeks to understand environmental problems, develop solutions, and promote sustainable practices.
Ecology
- Ecology studies the relationships between organisms and their environment.
- Key ecological concepts include:
- Populations: Groups of individuals of the same species in a given area.
- Communities: All the populations of different species in a given area.
- Ecosystems: All the living (biotic) and non-living (abiotic) components of an environment, and their interactions.
- Biomes are large terrestrial ecosystems characterized by specific climate conditions and plant communities.
Population Ecology
- Population growth is influenced by birth rates, death rates, immigration, and emigration.
- Exponential growth occurs when a population increases at a constant rate.
- Logistic growth occurs when a population growth slows as it approaches carrying capacity.
- Carrying capacity is the maximum population size that an environment can sustain.
- Factors limiting population growth include:
- Predation
- Competition
- Disease
- Environmental factors
Community Ecology
- Communities are complex networks of interacting species.
- Competition occurs when different species require the same limited resource.
- Predation is the interaction where one species (predator) hunts and kills another (prey).
- Predator-prey relationships can have a significant impact on the populations of both species.
- Symbiosis is a close interaction between two different species
- Examples include mutualism, commensalism, and parasitism.
Ecosystem Ecology
- Ecosystem ecology examines the flow of energy and matter within an ecosystem.
- Energy flows through ecosystems, starting with producers and moving to consumers and decomposers.
- Nutrients cycle within ecosystems, cycling between biotic and abiotic components.
- Nutrient cycles include the carbon cycle, nitrogen cycle, phosphorus cycle, and water cycle.
- Food webs show the feeding relationships between organisms in an ecosystem.
Biodiversity
- Biodiversity refers to the variety of life on Earth.
- It encompasses genetic diversity, species diversity, and ecosystem diversity.
- Biodiversity loss can have significant impacts on ecosystem health and human well-being.
- Habitat loss, pollution, and invasive species are major drivers of biodiversity loss.
Conservation Biology
- Conservation biology seeks to understand and protect Earth's biodiversity.
- Conservation strategies include habitat restoration, species protection, and sustainable resource management.
Environmental Problems
- Pollution is a significant environmental problem.
- Types of pollution include air pollution, water pollution, and soil pollution.
- Resource depletion is another environmental concern.
- Overuse of resources can lead to scarcity and environmental damage.
- Climate change is a global environmental issue, driven primarily by greenhouse gas emissions.
- Impacts of climate change include rising sea levels, extreme weather events, and disruptions to ecosystems.
Sustainable Practices
- Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs.
- Sustainable practices aim to minimize environmental impact and promote resource conservation.
- Examples of sustainable practices include:
- Using renewable energy sources
- Reducing waste and pollution
- Protecting biodiversity
Human Impact on the Environment
- Human activities have a significant impact on the environment.
- Examples include deforestation, urbanization, industrialization.
- The impact of human activity on the environment may include
- Overexploitation of natural resources.
- Climate change.
- Loss of biodiversity.
- Impacts are far-reaching.
