Overview of Environmental Science

Study Notes

Overview of Environmental Science

Interdisciplinary field that studies the interactions between the environment and human activities.
Combines principles from biology, chemistry, physics, ecology, geology, and social sciences.

Key Concepts

Ecosystems
- Interdependent communities of living organisms and their physical environment.
- Includes biotic (living) and abiotic (non-living) components.
Biodiversity
- Variety of life forms in an ecosystem; includes species diversity, genetic diversity, and ecosystem diversity.
- Critical for ecosystem resilience and function.
Sustainability
- Developing methods to meet current needs without compromising future generations.
- Focus on renewable resources, conservation, and reducing waste.
Pollution
- Introduction of harmful substances into the environment.
- Types include air, water, soil, and noise pollution.
- Impacts public health, wildlife, and ecosystems.
Climate Change
- Long-term alteration in temperature and typical weather patterns.
- Driven by greenhouse gas emissions from human activities.
- Consequences include rising sea levels, severe weather, and habitat loss.

Human Impact

Deforestation: Loss of forests due to agriculture, logging, and urban development.
Urbanization: Expansion of cities leading to habitat fragmentation and increased pollution.
Resource Depletion: Overuse of natural resources like water, minerals, and fossil fuels.

Conservation Efforts

Protected Areas: Establishing national parks and reserves to preserve ecosystems and biodiversity.
Restoration Ecology: Rehabilitating degraded ecosystems to restore their natural functions.
Conservation Biology: Study and conservation of biodiversity, focusing on endangered species and habitats.

Environmental Policies

Legislation aimed at protecting the environment (e.g., Clean Air Act, Endangered Species Act).
International agreements (e.g., Paris Agreement) to combat climate change and promote sustainability.

Current Challenges

Climate change adaptation and mitigation.
Pollution control and waste management.
Promoting renewable energy sources and reducing carbon footprint.
Balancing economic growth with environmental health.

Overview of Environmental Science

Interdisciplinary field examining interactions between the environment and human activities.
Integrates principles from various sciences: biology, chemistry, physics, ecology, geology, and social sciences.

Key Concepts

Ecosystems:
- Composed of interdependent living organisms and their physical surroundings.
- Includes biotic (living) and abiotic (non-living) elements.
Biodiversity:
- Represents the variety of life forms within an ecosystem, encompassing species, genetic, and ecosystem diversity.
- Essential for maintaining ecosystem resilience and functionality.
Sustainability:
- Focuses on meeting today's needs without hindering future generations.
- Emphasizes renewable resources, conservation efforts, and waste reduction.
Pollution:
- The introduction of harmful substances into the environment.
- Various types include air, water, soil, and noise pollution, all detrimental to public health and ecosystems.
Climate Change:
- Defined as long-term changes in temperature and weather patterns, primarily caused by greenhouse gas emissions from human activities.
- Results in rising sea levels, severe weather events, and loss of habitats.

Human Impact

Deforestation:
- Resulting from agriculture, logging, and urban expansion, leading to significant forest loss.
Urbanization:
- City expansion causes habitat fragmentation and increases pollution levels.
Resource Depletion:
- Overuse of essential natural resources such as water, minerals, and fossil fuels, leading to scarcity.

Conservation Efforts

Protected Areas:
- Creation of national parks and reserves aimed at preserving biodiversity and ecosystems.
Restoration Ecology:
- Focuses on rehabilitating degraded ecosystems to restore their natural balance and functions.
Conservation Biology:
- Studies and works to conserve biodiversity, with special attention to endangered species and habitats.

Environmental Policies

Comprised of legislation designed to protect the environment, including the Clean Air Act and Endangered Species Act.
Encompasses international agreements like the Paris Agreement to address climate change and promote sustainability initiatives.

Current Challenges

Addressing adaptation and mitigation strategies for climate change.
Implementing effective pollution control and waste management systems.
Advancing renewable energy sources while striving to lower carbon footprints.
Balancing economic development with the need for environmental protection.
