Are there environmental concerns?
There are severe environmental concerns. The route chosen through the Pacheco pass runs trough some very important wetlands. Henry Coe Park is a pristine area that will be severely compromised. In general Environmental groups would welcome CHSR because they perceive this method of transportation as producing less pollution and think Greenhouse gasses will be reduced relative to other modes of transportation. In the urban areas there are extreme concerns. In the Bay area, the route chosen runs along the existing Caltrain tracks and right-of-way. This means there will be 4 tracks instead of the existing 2 tracks. Also grade crossings at all intersections must be constructed. Some areas will demand condemnation of properties. Several Peninsula towns, such as Atherton and Menlo Park, have signaled their opposition to HSR because of the destructive intrusiveness it will be for their communities.
A. The primary environmental concerns about releases of transgenic fish, for example, include competition with wild populations, movement of the transgene into the wild gene pool, and ecological disruptions due to changes in prey and other niche requirements in the transgenic variety versus the wild populations. For example, transgenic tilapia (with cold tolerance similar to the unmodified species) might require little containment in the northern tier of the U.S., but might be excluded from the Gulf States altogether, where tilapia may be a serious exotic invader of freshwater streams and ponds. These site-specific concerns may make it necessary to control the sites where transgenic fish are reared and the level of biocontainment required might differ from site to site. Any biocontainment other than absolute containment will have to be assessed for specific proposed sites. Q. How will the public accept foods derived from transgenic animals? A. Germ-line transgenic modifications of anim
