Habitat destruction occurs when a natural habitat is converted to a non-natural one. This can be caused by human activities such as deforestation, urbanization, and pollution, as well as natural disasters such as floods, fires, and volcanic eruptions. Habitat destruction is one of the leading causes of extinction because it deprives animals of their food, shelter, and breeding grounds.
Overexploitation:
Overexploitation occurs when a species is hunted, fished, or harvested to the point of extinction. This can be caused by commercial activities, such as whaling, logging, and fishing, as well as by subsistence hunting and gathering. Overexploitation is often driven by human population growth and the increasing demand for resources.
Climate change:
Climate change is causing the Earth's temperature and weather patterns to change at an unprecedented rate. These changes are disrupting ecosystems and making it difficult for animals to survive. For example, rising sea levels are destroying coastal habitats, and changes in temperature are causing some animals to lose their food sources or their ability to reproduce.
Pollution:
Pollution can harm animals in a variety of ways. Air pollution can cause respiratory problems, water pollution can cause poisoning and disease, and land pollution can contaminate food sources. Pollution can also disrupt ecosystems by altering the balance of nutrients and organisms.
Invasive species:
Invasive species are non-native species that have been introduced to an area and have become a threat to native species. Invasive species can compete with native species for food, habitat, and resources, and they can also transmit diseases. Invasive species are often spread by human activities, such as trade and travel.
