overview causes of species Extinction answer
Answer (2)
Overview of the Causes of Species ExtinctionSpecies extinction is a complex and multifaceted issue, and there are several causes that contribute to it. Some of the main causes of species extinction include:Habitat Destruction and Fragmentation- Human activities such as deforestation, urbanization, and infrastructure development have led to the destruction and fragmentation of habitats, making it difficult for species to survive and thrive.- Habitat fragmentation can also lead to population isolation, reducing genetic diversity and increasing the risk of extinction.Overexploitation- Overhunting, overfishing, and the unsustainable harvesting of resources have led to the decline and extinction of many species.- The demand for products such as rhino horn, elephant ivory, and exotic pets has driven the overexploitation of many species.Climate Change- Climate change is altering ecosystems and disrupting the delicate balance of nature, leading to changes in population dynamics, migration patterns, and species interactions.- Rising temperatures, sea-level rise, and changes in precipitation patterns are all contributing to the decline and extinction of many species.Pollution- Pollution from human activities such as industrial processes, agriculture, and waste disposal is contaminating ecosystems and affecting the health and survival of many species.- Plastic pollution, in particular, is having a devastating impact on marine ecosystems, with many species becoming entangled, suffocated, or poisoned by plastic debris.Invasive Species- Non-native species can outcompete native species for resources, alter ecosystems, and even prey on native species, leading to their decline and extinction.- The introduction of invasive species can also lead to the loss of genetic diversity and the extinction of unique species.Human Population Growth and Expansion- The growing human population is placing increasing pressure on ecosystems and natural resources, leading to habitat destruction, overexploitation, and pollution.- The expansion of human settlements and infrastructure development is also leading to the fragmentation and destruction of habitats, making it difficult for species to survive and thrive.Other Causes- Other causes of species extinction include disease, parasites, and natural disasters, which can all have a significant impact on population dynamics and species survival.ConclusionSpecies extinction is a complex issue with multiple causes, and addressing it will require a comprehensive and multifaceted approach. By understanding the causes of species extinction, we can work towards developing effective conservation strategies and mitigating the impact of human activities on the natural world.HOPE THIS HELP
Answer:Species extinction occurs when a species completely disappears from Earth. This can happen naturally or due to human activities. The main causes include:1. Habitat Loss and DegradationDeforestation, urbanization, and agriculture destroy natural habitats.Wetlands, coral reefs, and forests are especially at risk.2. OverexploitationOverhunting, overfishing, and excessive harvesting for trade or resources reduce populations beyond recovery.3. Invasive SpeciesNon-native species can outcompete, prey on, or bring diseases to native species.4. PollutionChemicals (pesticides, plastics, oil spills) harm ecosystems.Air and water pollution affect survival and reproduction.5. Climate ChangeAlters temperature, weather patterns, and sea levels, disrupting ecosystems and species’ ability to adapt.6. DiseaseNew or spreading diseases can decimate populations, especially when immunity is lacking.Hope it's help!
