Can Biodiversity loss be the downfall of an ecosystem and human well be
People often say Why should I care if a species goes extinct? Its not essential to my daily life. tho what use are humans, really? We waste a lot of resources and have managed to damage the ecosystem without a second thought. Eliminating species to extinction, destroying plants and trees a critical part of human upbeat and organisms in an ecosystem leading to tremendous consequences. Organisms depend on each other for survival and the loss of matchless species can greatly alter the balance of an ecosystem as a whole, as seen in the Yellowstone National Park ecosystem. Gray wolves were poached to extinction from Yellowstone during the early twentieth century, then were reintroduced to restore a complete regimen web. Researchers, Marshall, Hobbs and Cooper the authors of Stream hydrology limits recovery of riparian ecosystems after wolf reintroduction suggested excessive browsing of willows by moose after wolves were gone was implicated in the slice of beavers from stream s. Furthermore, when the gray wolves disappeared the willows were terminated by elk glazing and with no willows to slow stream flow, creeks flowed faster and beavers prefer slow-moving water, so they disappeared as well. In lendition, when the wolves were reintroduced they hunted elk and brought down numbers of these. But, removing elk glazing wasnt enough for the willows, needing slow streams created by beavers allowing more willows to grow. Alan Tessier, program director in the National Science Foundations Division of Environmental biota whom funded the concludes the research illustrates the value of long-term ecological experiments to understanding how species interactions cascade through food webs to determine ecosystem resilience. Theref... ...vores, meaning no food for carnivores, meaning a lot quicker extinction of all life. In conclusion, losing even a small strand in the web of life contributes to the unraveling of our planets sustainability, and that makes a differenc e to each one of us.
