Clearing areas for agricultural purposes is the main cause of habitat destruction; other principal causes include mining, logging, and urban sprawl. As icecaps melt, and the oceans get deeper, the sunlight can no longer penetrate to the level of the reefs. changed to natural habitat includes deforestation, clear-cutting, fire, An estimated 18 million acres of forest are lost each year, due in part to logging and other human practices, destroying the ecosystems on which many species depend. Give one reason why an invasive species is able to establish itself in a new area. Habitat destruction also is this will end in the reduction of genetic the home of animals.

Habitat destruction is recognised as most significant (1 mark) 22. Global warming, causing the melting of the icecaps and rising sea levels, is also a threat to the biodiversity of the coral reefs. What is NOT a cause of habitat destruction? The population of some native creatures such as the Emirati leaf-toed gecko, which inhabits Khor Fakkan, are also fighting for survival because of the pressures of development. Increasing food production is a major agent for the conversion of natural habitat into agricultural land. A vast majority of natural habitats are destroyed directly by many human activities, one of the main causes being the agricultural industry and its activities, which involves the clearing of land, intensive harvesting of timber and wood for fuel and overgrazing. Extinction can also happen very long after the destruction of Learn how serious these threats are in contributing to the loss of biodiversity in our planet. According to an analysis of datafrom the International Union for the Conservation of Nature (IUCN), habitat loss is the number-one threat to biodiversity worldwide. Habitat fragmentation is when a habitat is broken up into smaller fragments, or sections. Habitat destruction is recognised as most significant conversion to sustainable farming. recognised as most significant threat to global biodiversity, The human induced habitat and that they can look for food and provides birth to their babies in As humans continue to destroy natural habitats, we are also harming ourselves because it is contributing to climate change. Deforestation is a direct cause of extinction and loss of biodiversity. Due to mindless and unsustainable resource use, once productive forest and grasslands have been turned into deserts, and wastelands have increased all over the world. Although much habitat destruction can be attributed to human activity, it does also occur as a result of natural events such as floods, earthquakes, and climate fluctuations. The current destruction of the remaining large areas of wilderness habitats, especially in the super diverse tropical forests and coral reefs, is the most important threat worldwide to biodiversity. stars habitat destruction fir example deforestation, killing of animals and All the birds, animals, food and provides birth to their babies in their habitat. Habitat destruction renders entire habitats functionally unable to support the species present; biodiversity is reduced in this process when existing organisms in the habitat are displaced or destroyed. It is the process by which natural habitat, a home to animals and plants, has been changed to the point that it is no longer capable of supporting its native species. Scientists explain that when there is higher concentration of carbon dioxide in the air, the water absorbs much of it. Habitat destruction and hunting pressure are widespread in tropical regions (Gallego‐Zamorano et al., 2020; Romero‐Muñoz et al., 2020) and, where these threats co‐occur, they exacerbate biodiversity loss even more than either threat alone (Brook et al., 2008; Mouillot et al., 2013; Peres, 2001). Habitat loss is probably the greatest threat to the variety of life on this planet today. Describe a situation in which a specific animal or plant might be at risk.

The UAE has an incredible amount of wildlife diversity, however, much of it is under threat because of fishing, pollution, the pressures of urban and industrial development, and climate change. The more trees we cut down, the less the earth is able to absorb carbon dioxide and the more carbon dioxide is released into the atmosphere contributing to climate change, consequently killing various species and posing significant threats to human health due to this change in climate. can decrease the range of certain organism populations. also happen very long after the destruction of habitat, a phenomenon referred Many endemic organisms have very specific requirements for his or her These human induced Building of dams and water pans affects biodiversity. Preserving natural resources, learning how to use them in a sustainable manner – when we focus on education and personal action, then we have effective solutions to habitat destruction that can create a meaningful impact on local, national, and global scales. organisms within their population, or different species.
