Study Notes
Human Activities Affecting Ecosystems
- Agriculture: Over 40% of Earth's surface is now used for agriculture, replacing forests. Fertilizers harm soil, land, and water systems.
- Deforestation: Destroys wildlife, contributes to climate change (reduced CO2 absorption), and displaces indigenous peoples. Almost half of the planet's trees have been lost since the Industrial Revolution.
- Overpopulation and Overconsumption: Humans require large amounts of space and resources, leading to deforestation and use of non-renewable resources.
- Plastic Production and Chemicals: Plastic waste and chemicals pollute the environment, including oceans, disrupting cell biology in organisms.
- Greenhouse Gas Emissions: Increases global temperatures and causes extreme weather events (heatwaves, flooding, hurricanes). Impacts ocean and land ecosystems and food webs.
- Coral Reef Destruction: Water pollution, climate change, overfishing, and ocean acidification destroy coral reefs—critical fish habitats.
- Freshwater Aquifer Depletion: Intensive agriculture drains rivers and aquifers, affecting diverse plant and animal life.
- Overhunting and Overexploitation: Natural resources, such as fish stocks, are depleted by overfishing and mining, affecting food chains.
- Invasive Species: Non-native species disrupt food chains and compete with native species, potentially devastating them.
Sustainable Practices in Agriculture
- Reducing Reliance on Pesticides: Shift to natural processes (e.g., introducing insect predators) and crop rotation. Mechanical weed removal.
- Crop Rotation: Improves soil fertility.
- Hydroponics and Aquaponics: Water-efficient plant growth systems using water from fish waste.
- Urban Agriculture: Growing food in cities.
- Agroforestry: Integrating trees and crops in farming for better soil stability and drought resistance.
- Permaculture: Mimicking natural ecosystems by planting multiple crop species together.
- Cover Crops: Prevent soil erosion and suppress weeds.
- Soil Enrichment: Using composted plant material or manure for better soil quality.
- Water Management: Implement efficient irrigation techniques and rainwater harvesting.
Sustainable Practices in Various Communities
- Mother Earth as a Living Being: Respect and avoid harming the environment because it's a living entity.
- Laws of Nature: Recognize environmental rhythms (e.g., seasons) to avoid harming during vulnerable periods.
- Interconnectedness: Understanding interconnectedness between elements of the environment and respect for all things.
