As on the present condition of the Earth, Soils are eroding, water tables are falling, fish stocks have almost vanished and the glaciers have melted. With this, the growing population of 80 million every year is alarming. Billion people sleep hungry each day. Few years later, mostly in poor countries, there will be more than two billion people to feed. According to Thomas Malthus 1798, the world population grows faster than the supply of food, until famine. Diseases and war will arrive to decrease the number of growing people.
The Fertility Decline had reached different countries at different times but it reached France first. By the late 19th century, fertility in France had reduced to 3 children per woman without use of advanced contraceptives. Till the enlightenment, the concept was that its God who decide the number of children, people couldn’t workout that it’s up to them. Other countries in west were seen following France but then came the baby boomers with the bust catching demographers again off the guard.
The saddening part is that by 2030, the biggest generation of the adolescent in the history will reach their childbearing age. If each woman bears only two children then even the population will grow crazily. Bangladesh is the most densely populated nation while the highest threats of climate change. Another alarming case is of Rwanda. Jared Diamond in his book, Collapse, argued that the genocidal massacre of 800,000 Rwandas in 1994 was not just the ethnic hatred but the reason was also over population as farmers had to divide the same amount of lands in more small pieces because of over population.
Global warming can be of important consideration. According to Brian O’Neill of the National Center of Atmospheric Research, if the population reaches 7.4 billion instead of 8.9 billion by 2050, then the reduced carbon emission can be of 15%. Considering that population is the only concern is wrong. In order to reduce global warming we have to shift from fossil fuel to some alternative energy regardless of growing population.
