Climate Change: Global temperature increases, shifts in precipitation patterns, melting of glaciers, and rising sea levels affect ecosystems, water resources, and habitats for many species.
Habitat Destruction: Urbanization, deforestation, mining, and other human activities can result in the loss or fragmentation of habitats, leading to population declines or even species extinctions.
Pollution: The release of pollutants such as industrial chemicals, pesticides, fertilizers, and plastics can contaminate ecosystems and harm plant and animal life.
Overexploitation: Excessive hunting, fishing, and harvesting can deplete populations and impact the entire ecosystem.
Invasive Species: Non-native species introduced to an ecosystem can outcompete native species for resources, leading to declines or displacements.
Deforestation: The clearing of large areas of forest reduces biodiversity, alters rainfall patterns, and worsens climate change impacts.
Ocean Acidification: Increased levels of carbon dioxide in the atmosphere lead to ocean acidification, affecting the ability of marine organisms to build shells or skeletons.
Changes in Water Availability: Altered precipitation patterns, melting ice caps, and increasing frequency of droughts or floods disrupt ecosystems that depend on water.
Disease: Changing environmental conditions can favor the spread of diseases among plant and animal populations, leading to potential population declines.
Overpopulation: Human population growth puts pressure on natural resources, causing competition for food, water, and space, leading to resource scarcity and biodiversity declines.
Natural Disasters: Events like earthquakes, tsunamis, wildfires, and hurricanes can cause substantial habitat damage and affect plant and animal populations.
These changes can disrupt ecological interactions, threaten species survival, alter food chains, and ultimately reduce biodiversity.
