Producing fish for human consumption, counteracting overharvesting
Study Notes
Human Impact on Non-Human Species
- Human activities affect non-human species in various ways, including habitat destruction, overharvesting, and introduction of invasive species.
Resources Harvested by Humans
- Humans harvest various resources from the Earth, including food, water, and raw materials.
Consequences of Habitat Fragmentation
- Habitat fragmentation caused by human activities leads to isolated species populations, making them more vulnerable to extinction.
Disruptors of Natural Balance
- Humans introduce invasive species, pollutants, and other substances into ecosystems, disrupting the natural balance.
Impacts of Human Activities on the Environment
- Human activities contribute to climate change, pollution, and habitat destruction, among other environmental issues.
Food Sources for Humans
- Humans harvest various food sources, including crops, livestock, and seafood.
Destructive Human Activities
- Destructive human activities to natural habitats include deforestation, mining, and construction.
Threats to Biodiversity
- Habitat destruction and fragmentation are among the biggest threats to biodiversity.
Purpose of Wildlife Corridors
- Wildlife corridors aim to connect isolated habitats, allowing species to migrate and maintain genetic diversity.
Overharvesting Examples
- Overfishing is an example of overharvesting, where excessive fishing depletes fish populations.
Impact of Dams on Habitat Fragmentation
- Dams contribute to habitat fragmentation by blocking species migration routes and dividing habitats.
Consequences of Habitat Fragmentation on Species Populations
- Habitat fragmentation can lead to population decline, isolation, and even extinction.
Impacts of Overharvesting on Marine Ecosystems
- Overharvesting in marine ecosystems can cause population decline, disrupt food chains, and alter ecosystem balance.
Purpose of Sanctuary Zones in Marine Conservation
- Sanctuary zones in marine conservation provide protected areas for species to thrive and maintain ecosystem balance.
Contribution of Fish Farms to Ecological Conservation
- Fish farms can contribute to ecological conservation by reducing the demand on wild fish populations and promoting sustainable aquaculture practices.
