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.
