Why should Europe be concerned with changes in population trends? please help!!!

As of 2018, Europe has a total population of over 741 million people. Europe's population growth is comparatively low, and its median age comparatively high, in relation to the world's other continents, especially compared to Asia, Africa and Latin America.

Explanation:

The total population grew by 1.4 million

Explanation:

Twenty European countries had population gains in 2010, while seven countries had population declines, according to a report released by Eurostat, the statistical agency of the European Union. The total population grew by 1.4 million, to 502.5 million as of January 2011, according to provisional data. The countries with declines, mainly in Eastern Europe, included Bulgaria, Germany, Latvia, Lithuania, Hungary, Portugal and Romania.

Most of the European Union’s population growth (900,000, or 62%) was due to net migration; the remainder (500,000, or 38%) came from natural increase, which is the number of births minus the number of deaths.

Overall, as the report points out, migration to European Union nations has accounted for a growing share of population increase since the mid-1980s, both because migration has risen and births have declined. The number of European Union births decreased in 2010 for the second year in a row. In general, births decrease during economic hard times, and, according to a Pew Research Center report, a decline in the U.S. birth rate has been linked to the recession.

Fertility rates already are low in some European nations, and the number of deaths is expected to rise as the baby boom generation ages. Therefore, “negative natural change (more deaths than births) cannot be excluded in the future,” the report notes. In the United States, West Virginia was the only state to have more deaths than births from 2000-2009, according to a report on natural decrease from the Carsey Institute; its analysis also indicates that one in four U.S. counties had more deaths than births last year.

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
