Reefs and Dunes Play Critical Roles in safeguarding Lives in US Coastal Regions
When rising sea levels and excessive weather conditions have already put 16% of U. S. coastlines at "high-hazard" risk; in a recent study carried out by researchers of Stanford University it has been found that if natural habitats like sand dunes, sea grasses, coral reefs, and mangroves aren't protected, it would threatened twice the number of residents here.
Last October when due to the Superstorm Sandy in US, the mid-Atlantic coast was entirely devastated, a lot many lives were taken. With an initiative to avoid such situation once again, this study has been carried out.
It says when around 23 of the 25 most heavily populated U. S. counties are coastal it becomes essential to set out "hardening" seashores with billion-dollar sea walls. According to the study, if such habitats are preserved, it would prove to be a simpler and cheaper substitute in some areas.
As said by the lead author and Stanford scientist Katie Arkema in announcing the findings, published in the peer-reviewed journal Nature Climate Change "If we lose these defenses, we will either have to have massive investments in engineered defenses or risk greater damage to millions of people and billions in property".
According to researchers, with the existence of natural habitats, it is possible to protect two-thirds or 67% of U. S. coastlines.
