the world’s population is about to reach a landmark of huge social and economic
importance, when the proportion of the global population over 65 outnumbers children under 5 for

consequences for both rich and poor nations.
the rate of growth will shoot up in the next couple of years. 2 a combination of
the high birth rates after the second world war and more recent improvements in health that are
bringing down death rates at older ages. separate un forecasts predict that the global population
will be more than nine billion by 2050.
the us census bureau was the first to sound 3 its latest forecasts warn
governments and international bodies that this change in population structure will bring widespread
challenges at every level of human organization, starting with the structure of the family,
as people live longer. this will in turn place new burdens on careers and social
services providers, 5 for health services and pensions systems.

По замыслу у строителей тематический парк - это центр семейного отдыха и развлечений, что во многом определяет выбор самой темы. Чтобы объединить людей разных возрастов и, в первую очередь, привлечь взрослое население, она должна носить не только увеселительный, но и информационно-познавательный характер.
Парки могут создаваться вокруг самых разнообразных тем: история, культура, география, спорт и т.д. Некоторые из них посвящены всецело одной теме, другие затрагивают разные темы, например парк King’s Island в Огайо (он разделен на шесть тематических зон: Речной город, Дикие животные, Интернациональная улица). Другой пример - парк Great America в Калифорнии - центр семейного отдыха, где на площади 100 акров размещены Площадь родного городка, Территория Юкон, Гавань Янки, Деревенская ярмарка и Новый Орлеан.
