Habitat loss occurs when a natural area is converted to another use, such as agriculture, development, or mining. Habitat degradation occurs when a natural area is damaged or destroyed, making it less suitable for the species that live there.<\/p>\n<p>Habitat loss and degradation can be caused by human activities, such as deforestation, pollution, and climate change. They can also be caused by natural disasters, such as floods, fires, and earthquakes.<\/p>\n<p>Habitat loss and degradation can have a devastating impact on species. When a species loses its habitat, it can no longer find food or shelter. This can lead to starvation, disease, and death. Habitat loss can also make it difficult for species to reproduce.<\/p>\n<p>Habitat loss and degradation is a major threat to biodiversity. It is estimated that one-fourth of all species on Earth are at risk of extinction due to habitat loss and degradation.<\/p>\n<p>Agricultural activities, extraction (including mining, fishing, logging), and development (human settlements, industry) can also contribute to species extinction, but they are not as significant as habitat loss and degradation.<\/p>\n<p>Agricultural activities can lead to habitat loss and <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> degradation when land is cleared for crops or grazing.
