Study Notes
Sustainability
- Meeting the needs of the present without compromising the ability of future generations to meet their own needs
- Social equity ensures fairness and justice in resource distribution
- Economic viability promotes long-term economic growth and development
- Environmental stewardship involves responsible management of natural resources
- Sustainable development goals include eradicating poverty and hunger, ensuring access to education, healthcare, and clean water, promoting sustainable agriculture and energy practices, and protecting and preserving natural resources and ecosystems
Pollution
- Introduction of harmful substances or contaminants into the environment
- Types of pollution include air, water, soil, and noise pollution
- Human activities, such as industrial processes, transportation, and agriculture, cause pollution
- Natural sources, such as volcanic eruptions and wildfires, also contribute to pollution
- Effects of pollution include respiratory problems, cancer, neurological damage, ecosystem disruption, and biodiversity loss
Climate Change
- Long-term warming of the planet due to increased greenhouse gases
- Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, contribute to climate change
- Human activities, such as burning fossil fuels, deforestation, and agriculture, release greenhouse gases
- Effects of climate change include rising global temperatures, sea-level rise, changes in precipitation patterns, loss of biodiversity, and food and water insecurity
Conservation
- Preservation and protection of natural resources and ecosystems
- Conservation maintains ecosystem services, preserves biodiversity, and supports human well-being
- Conservation strategies include establishing protected areas, promoting sustainable use, and restoring degraded ecosystems and habitats
Ecosystems
- Interacting components of the environment, including living and non-living elements
- Ecosystems consist of biotic factors, such as plants, animals, and microorganisms, and abiotic factors, such as light, temperature, water, soil, and nutrients
- Types of ecosystems include terrestrial, freshwater, and marine ecosystems
- Ecosystem services include provisioning, regulating, and cultural services, such as providing food, water, and recreation, regulating the climate, and offering spiritual values
Sustainability
- Meeting the needs of the present without compromising the ability of future generations to meet their own needs
- Based on three key principles:
- Social equity: fairness and justice in resource distribution
- Economic viability: long-term economic growth and development
- Environmental stewardship: responsible management of natural resources
- Aims to achieve several goals, including:
- Eradicating poverty and hunger
- Ensuring access to education, healthcare, and clean water
- Promoting sustainable agriculture and energy practices
- Protecting and preserving natural resources and ecosystems
Pollution
- Introduction of harmful substances or contaminants into the environment
- Four main types of pollution:
- Air pollution: gases and particles in the atmosphere
- Water pollution: chemicals and waste in water bodies
- Soil pollution: chemicals and waste in soil
- Noise pollution: excessive noise levels
- Caused by human activities, such as industrial processes, transportation, and agriculture, as well as natural sources like volcanic eruptions and wildfires
- Effects on human health and the environment:
- Respiratory problems, cancer, and neurological damage
- Ecosystem disruption, biodiversity loss, and environmental damage
Climate Change
- Long-term warming of the planet due to increased greenhouse gases
- Caused by greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, and human activities like burning fossil fuels, deforestation, and agriculture
- Effects on the environment and human societies:
- Rising global temperatures, more frequent and severe heatwaves, droughts, and storms
- Sea-level rise, coastal erosion, flooding, and saltwater intrusion
- Changes in precipitation patterns, leading to droughts, floods, and disruptions to agriculture
- Consequences of climate change:
- Loss of biodiversity, extinction of species, and disruption of ecosystems
- Food and water insecurity, decreased crop yields, and changed growing seasons
Conservation
- Preservation and protection of natural resources and ecosystems
- Importance of conservation:
- Maintaining ecosystem services, such as clean air and water, soil formation, and climate regulation
- Preserving biodiversity, protecting endangered species and ecosystems
- Supporting human well-being, providing food, water, and recreation
- Conservation strategies:
- Establishing protected areas, such as national parks, wildlife reserves, and conservation easements
- Promoting sustainable use, such as responsible harvesting of resources and eco-tourism
- Restoring degraded ecosystems and habitats
Ecosystems
- Interacting components of the environment, including living and non-living elements
- Components of ecosystems:
- Biotic factors: plants, animals, microorganisms
- Abiotic factors: light, temperature, water, soil, nutrients
- Types of ecosystems:
- Terrestrial ecosystems: forests, grasslands, deserts
- Freshwater ecosystems: rivers, lakes, wetlands
- Marine ecosystems: coral reefs, estuaries, open ocean
- Ecosystem services:
- Provisioning: providing food, water, and other resources
- Regulating: climate regulation, pollination, pest control
- Cultural: recreation, tourism, spiritual values
