I think the best answer is B. Both are controversial since both projects are very destructive to the environment. Environmental issues rise during the Pacua Dam and the Intercoastal Highway Projects. The construction of these projects are said to destroy and damage ecosystem.

Answer: The greater the distance to a galaxy, the greater its redshift</h2>
When we talk about the <u>visible electromagnetic spectrum</u>, we know it starts in violet-blue and ends in red.
Now, in this context the astronomer Edwin Powell Hubble observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed the spectral lines were displaced towards the <u>red</u><u> </u>(red shift), whereas the nearby stars showed a spectrum displaced to the <u>blue</u>.
From there, Hubble deduced that the farther the galaxy is, the more redshifted it is in its spectrum, and noted that all galaxies are <em>"moving away from each other with a speed that increases with distance"</em>, and enunciated the now called<u> Hubble–Lemaître Law</u>.
This means in the past the distance between two galaxies was smaller than at present, being this the proof that <u>the universe is expanding</u> (like a balloon expands when it is filled with air or another gas).
At this poitn it is important to stay clear that <u>the redshift is not produced by the relative movement of the galaxies with each other</u>. This effect is in fact, due to the <u>own expansion of the space</u> among the galaxies.
Answer:
Desde el siglo III d.C. el Imperio Romano entró en un proceso de crisis alimentada por los ataques de los pueblos bárbaros (término que debe traducirse por extranjero), tanto en el continente europeo como en la parte asiática; la debilidad del ejército, y la crisis económica.
It will harm the ecosystem pretty horribly. The water wouldn't have really anywhere to go. Hope that helps.
