30. Will species be able to survive current climate change? Maybe Maybe not

31. New Complications with Climate Change 1.Current species and populations are already stressed by habitat loss and environmental degradation 2.Habitat loss will make it harder for species to migrate to new areas 3.Global temperature may increase to temperatures that are much greater than species experienced in the past 4.Rate of global climate change is probably faster than in geologic past

34. Habitat Loss Orange County, California

37. Habitat Loss Habitat is the physical and biological environment used by an individual, a population or a species Habitat degradation is the process by which habitat quality for a given species is diminished Habitat loss occurs when the habitat quality for a given species is so low that the environment can no longer support the species

38. Ecosystem Loss Ecosystem is a group of organisms and their physical environment Ecosystem degradation occurs when alterations to an ecosystem degrade or destroy habitat for many of the species that constitute the ecosystem Ecosystem loss occurs when the changes to an ecosystem are so great and so many species typical of that ecosystem (especially dominant species) are lost that the ecosystem switches from one type to another

39. What are the main processes that degrade habitat and ecosystems?

40. Processes that degrade habitat and ecosystems Contamination/Pollution Human built structures Soil erosion Changing fire regimes Changing water use and hydrology Deforestation Desertification Draining wetlands
