Europe and Russia have experienced population declines over the last couple of decades. The birth rate decline has led Europe to what today is an aging population. Although a lower birthrate is not necessarily a bad thing‚ this creates an uneven population. Everything in nature is good in moderation and when it comes to nature and humans‚ homeostasis is key. If you have the baby boomer population all aging at the same time and a low birthrate‚ this can negatively affect Europe and Russia socially

When you look at the bees population in the U.S. from the past and compare it to now‚ It is very obvious there is a problem. In recent years the bee population has been declining somewhat rapidly do to an unknown cause. It is very obvious that bees play an important role in the ecosystem and for humans.

The Worldwide Amphibian Decline Introduction Amphibians are extremely vital in the ecosystem as secondary food consumers since they are the prey items for vertebrates and invertebrates and control the biological pest. However‚ in recent years there has been a rather huge extinction of all kind of species recorded around the world. They are declining in an alarming rate‚ with over 43 percent of species in a state of decline (Lips et al.‚ ND). Amphibians‚ such as frogs‚ toads‚ salamanders

“The size of Europe Population was around eighty million and it decrease to fifty million after the black plague had hit (Ole J. Bendeictow)”. With the black plague taking reducing the population it caused Europe fifty years to recover from their loss. The importance of the Europe’s population decline from the black plague it resulted in a better and cheaper value on the labour. In 1381 it was followed right after that value to increase it caused the peasants to revolt and the farming to change.

1. How big is the problem of amphibian decline? Give several examples and be quantitative. The problem dealing with the decline of amphibians is a lot larger than most people understand. The declines are at an all-time high which is forcing most species to be near extinction. There is not just one causative factor to blame for this devastating news; there are many potential causes that are resulting in these numbers. The various declines can be linked to countless natural forces such as predation

The Decline of The Bee The bee is a vital part of human existence. They pollinate‚ giving life to plants‚ animals‚ and in turn‚ man. If they were to die out‚ the human race would follow suit in a mere matter of years. 65% of all flowering plants require bees for pollination‚ and the percentage being higher for the major crop plants‚ like corn and wheat. These crops account for $47.1 billion every year. Honey bees are responsible for one-third of the food we eat‚ meaning no bees equals no food.

Growth and Decline. The occurrence of Urban Growth in the Pyrmont-Ultimo region of Sydney has become well known due to the significant increase in population and the restoration of houses‚ buildings and other structures. This matter of Urban Growth is relevant to Australia on both a local and regional scale because it contributes to Sydney ’s total population. If the population of the Pyrmont-Ultimo region was to rapidly decline‚ it would be crucial to increase and maintain the population as it reflects
