Although the light year is a
commonly used unit, astronomers
prefer a different unit called the parsec (pc). A parsec, equal to 3.26
light years, is defined as the distance at which 1 Astronomical Unit subtends an
angle of 1 second of arc (1/3600 of a degree) When we use the parsec for really
large distances, we often put a prefix in front of it - like kiloparsecs (kpc),
which are equal to 1000 parsecs - or Megaparsecs (Mpc), equal to a million
parsecs.
The Milky Way is about 1,000,000,000,000,000,000 km
(about 100,000 light years or about 30 kpc) across. The Sun does not lie near
the center of our Galaxy. It lies about 8 kpc from the center on what is known
as the Sagittarius arm of the Milky Way.

Answer:
The Pampas region has a big economic impact as it is the agricultural heart of Latin America.
Explanation:
The Pampas is a region that is mostly comprised of lowlands. Naturally, it is a biome where grasses dominate. The soil is highly fertile and the region as it is is relatively large. Humans have easily seen the potential of the Pampas and spend no time converting it in an agricultural landscape.
Latin America is a region that heavily relies on agriculture, both farming and raising cattle. Large, relatively flat land with fertile soil is excellent for farming, so the Pampas has been heavily exploited for the large-scale production of agricultural goods. Also, raising cattle is among the highest in the world in Latin America and it is constantly growing as a sector, and grasslands are needed to sustain the cattle, so the Pampas again is the place to exploit for it. While this has a big and positive economic impact, the effects on the flora and fauna of the Pampas have been devastating, to say the least.
