Currently, the most biodiverse regions of the planet are located near the equator. In this lesson, students closely read a passage about changes in biodiversity in North America, and they cite textual evidence to answer research-based comprehension questions. The underlying causes of biodiversity loss, such as a growing human population and overconsumption are often complex and stem from many interrelated factors. Climate change, biodiversity and health. Changes to an ecosystem's biodiversity can have a direct effect on humans because humans-answer choices . A different Native American tribes and the ways in which they obtained food B natural environments and the way changes can affect those environments C pesticides used by farmers and the harmful effects of those pesticides on humans D a pod of whales that cannot go to its usual feeding area in Alaska because of Questions: Changes in Biodiversity . Major direct threats to biodiversity include habitat loss and fragmentation, unsustainable resource use, invasive species, pollution, and global climate change. Figure 1. The MA scenarios address the consequences of different plausible futures for ecosystem services and human well-being (S5). Climate is an integral part of ecosystem functioning and human health is impacted directly and indirectly by results of climatic conditions upon terrestrial and marine ecosystems. changes are associated with change … Climate Change And Biodiversity. depend on the Earth's natural resources. inhabit all areas of the Earth's ecosystems. Biodiversity change is uncoupled from species richness trends: consequences for conservation and monitoring. Biodiversity is threatened by a variety of global changes resulting from the combined actions of human society. We do not know how and why belowground biodiversity may change as soils develop over centuries to millennia, hampering our ability to predict the myriad of ecosystem processes regulated by belowground organisms under changing environments. use minerals from the ground to make things. The scenarios developed by the MA project continued loss of biodiversity, with attendant changes in ecosystems services and declines in human well-being in some regions and populations. Biodiversity provides numerous ecosystem services that are crucial to human well-being at present and in the future. SURVEY . It is well known that deforestation leads to an increase in atmospheric carbon dioxide which can contribute to climate change, 81 and regeneration of natural forests has been suggested as a way to reduce future global temperature increases. This lesson is appropriate for students in 8th, 9th, 10th, 11th, and 12th grades. How biodiversity in North America changed over time. The most direct threats are overharvesting and loss/disturbance of habitat resulting from conversion of natural ecosystems to human use (thick red arrow). A specific assessment of changes in ecosystem services for the United States as a consequence of changes in climate or other drivers of change … 60 seconds . Changes in the biodiversity matter because they directly affect the benefits that forests provide for people, such as clean air and a brake on climate change. Global Scenarios and Ecosystem Change. Changes in natural resources is the root cause of all biodiversity loss epidemiology may already be underway, complex biological (Sharma and Mishra, 2011). Biodiversity Findings • It is difficult to pinpoint changes in ecosystem services that are specifically related to changes in biological diversity in the United States.
