Study Notes
Ecosystem Interactions
- Various interactions, such as predation, competition, and symbiosis, play crucial roles in influencing ecosystem stability.
- Changes in species populations and their relationships can lead to shifts in ecosystem balance and health.
Processes Not Involved in Ecosystem Stability
- Certain human activities, such as urbanization and industrialization, do not contribute to maintaining stable ecosystems but rather disrupt them.
Effects of Plastic Use on the Environment
- Excessive plastic use leads to pollution and waste, adversely impacting wildlife and natural habitats.
- Plastics take hundreds of years to decompose, causing long-lasting environmental issues.
Impact of Plastic Bags on Marine Animals
- Marine animals may ingest plastic bags, mistaking them for food, leading to internal injuries or starvation.
- Entanglement in plastic waste can also result in injury or death for various marine species.
Initiative to Reduce Plastic Waste
- Initiatives like banning single-use plastics and promoting reusable alternatives are essential in tackling plastic waste issues.
Human Impact on Ecosystem Stability
- Deforestation, pollution, and urban sprawl are clear examples of human impact that destabilize ecosystems through habitat destruction and resource depletion.
Importance of Environmental Conservation
- Conserving the environment is vital for maintaining biodiversity, which sustains ecosystem services essential for human survival.
Singapore Initiatives Against Plastic Use
- Singapore has implemented measures such as plastic bag charges, public awareness campaigns, and beach clean-ups to combat plastic pollution.
Common Pollution Effects on Ecosystems
- Pollution can lead to a loss of biodiversity, toxic accumulation in food webs, and the degradation of natural habitats.
Agriculture's Negative Environmental Impact
- The intensive farming of crops and livestock can result in habitat loss, soil degradation, and increased greenhouse gas emissions.
Microplastics in Human Diet
- Microplastics can infiltrate food chains, eventually making their way into human diets through seafood consumption and water sources.
Initiative to Reduce Plastic Waste Pollution
- Initiatives like the "Keep Singapore Clean" campaign focus on reducing littering and encouraging recycling.
Wasting Earth's Resources
- Overconsumption of natural resources, like water or energy, exemplifies human actions that waste limited Earth's resources.
Importance of Reducing Negative Environmental Impacts
- Mitigating harmful human activities is crucial for promoting ecological balance and ensuring resource availability for future generations.
Pollutants and Ecosystem Destabilization
- Pollutants can disrupt food chains, alter habitats, and decrease species diversity, leading to overall ecosystem destabilization.
Purpose of Bloobin
- Bloobin aims to raise awareness of plastic waste and encourage the adoption of eco-friendly practices in everyday life.
Key Impacts of Human Activities
- Human activities, such as pollution and habitat destruction, are key factors that compromise the stability and health of ecosystems.
Supermarkets and Plastic Bag Charges
- Charging for disposable plastic bags incentivizes consumers to choose reusable options, thereby reducing plastic consumption and waste.
