Study Notes
Human Environmental Impacts
- Human activities are putting pressure on the Earth's resources and habitat, leading to starvation, loss of habitat, and extinction of non-human species.
- The Earth provides everything humans need to survive, including resources for food, shelter, and energy, but human consumption is depleting these resources.
- Human activities such as deforestation, mining, and pollution are causing habitat destruction and fragmentation, leading to loss of biodiversity and ecosystem disruption.
Habitat Loss and Fragmentation
- Habitat fragmentation occurs when human activities divide larger habitats into smaller, disconnected spaces, or eliminate them completely.
- Habitat loss and fragmentation are the biggest threats to biodiversity, causing animals to lose access to resources and increasing their risk of extinction.
- Fragmentation can occur in urban and rural areas, and is caused by activities such as logging, dam construction, and coastal development.
- It can lead to inbreeding, disease, and local extinction, and can have a ripple effect on entire ecosystems.
Overharvesting
- Humans consume more resources than they need, leading to overharvesting and depletion of plant and animal populations.
- Overharvesting is prevalent in industrialized countries, particularly in the oceans, where some species are being fished to near extinction.
- Clear-cutting forests and poaching are also forms of overharvesting, leading to the decline of species such as tigers, rhinoceroses, and elephants.
Ecological Conservation
- Ecological conservation can help counter human environmental impact through the use of wildlife corridors, strict poaching laws, and armed guards to protect imperiled species.
- Reforestation, ocean protection, and sanctuary zones can help restore habitats and prevent overfishing and pollution.
- Fish farms and urban gardens can help reduce the pressure on natural resources, and new technologies such as water permeable roadways can reduce waste and conserve water.
- Ecological conservation management and planning can help humans and nature coexist sustainably.
