Blowout Preventer The second line of defense for the workers and the well to prevent a blowout is the group of equipment called blowout preventers (BOPs). BOPs and associated valves are installed on top of the casing head before drilling ahead after rigging up. These high-pressure safety valves and associated equipment are designed to shut off the well hole and prevent the escape of the underground fluids and prevent a blowout from occurring. symbol,vector,illustration,fossil fuel,extraction,exploration,offshore,drilling,BP,Deepwater Horizon,spill,safety,environmental degradation

Homeowner is allowed to fill in wetlands On a property that was grandfathered to build on a tiny waterfront lot, the owner was allowed by the local zoning department to fill in a low wetland where his well (white pipe) and dock electric service (right center of photo) were located. As this photo documents, this low area was frequently flooded. sea level rise,flooding,critical area,development,Talbot County,Maryland

Acacia koa (Koa tree) Front view illustration of a Koa tree, endemic to the Hawaiian islands. There are actually two species of koa native to Hawaii. The large forest koa is well known around the world for the beautiful hard wood. Koa's smaller cousin, koai?a, that once grew in the lowlands of most of the main Hawaiian Islands, has an even harder wood that is much prized for its gnarled grain. symbol,vector,illustration,koa,tree,shrub,native,Angiosperms,Eudicots,Rosids,Fabales,Fabaceae,Acacia,Hawaii
