If one bank of a river is disturbed and begins to crumble, water fills the hole and sweeps away loose dirt. Over time, this creates a bigger and bigger hole in the river bank. As the water begins to rush faster through the new opening, it slows on the opposite river bank. Because slow-moving water can’t carry as much weight as fast-moving water, loose dirt and rocks build up on that side, making it more shallow. Eventually, the build-up creates new land and a new curve in the river’s watercourse.The new curve causes the water running against the outside bank to pick up enough momentum that it slams into the opposite bank further down the river, creating another curve. As more time passes, the rushing water creates more and more curves downstream
No, as more people exit the window of fertility (some of whom without children) their life begins to become more dependent on other people. At first it will be small things, but as people reach their 80s, care homes are usually the only place for them. An elderly population means that younger skilled workers are more likely to leave, as they are less inspired in an ageing economy, and they take their talent with them. It leads to population decline, negligence of many industries and almost would have to be supported by a governmental health program. This is why many view immigration as a good thing. As younger people from poorer countries are attracted to high salaries and freedoms, they produce children and begin to fill some of the gaps in birth rate. However, this ultimately leads to cultural dilution in the host country, which many (especially the old) don’t want.
