Answer:
Minimizing economic, environmental, and human costs related to extreme weather is a difficult problem for public infrastructure because New York´s geography feautures include 520 miles of shoreline, marshes, beaches, harbors and waterfonts implying an big magnitude of costs requiring a wide range of adaptive strategies to bulid up resilience to hazard from extreme weather, but not as an immediate benefit.
Explanation:
New York has always been a waterfront city, therefore Hurricane Sandy’s significant flood and destruction reminded the governments on precedents around the world about extreme weather global complex issues that the city is facing as an urban waterfront community.
New York City with its unique features, coped with storm´s coastal flooding disaster and recognizes it needs to cope with the challenges of increasing risk that climate change, sea level rise and coastal storms involve. But the storm city´s resilience imply high-costs-strong measures to plan for coastal risks aid in short- and long-term robust infrastructure projects considering the special design for waterfront communities by the means of making the city safer and healthier, but still vibrant and prosperous, vital and sus
tainable.
Although critical, planning for the future of these projects depends on budget management associated with each strategy for New York City comprehensive waterfront plan, as this framework requires gigantic public and private investment for ensuring healthy waterways, a strong port, the ecological protection of nat
ural habitats, the public’s enjoyment of the shoreline, and the economic benefits of in our waterfront trying to understand the magnitude and benefits in the future and in case of disasters.

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.
