作为地球上的现状,土壤侵蚀,水位正在下降,鱼类资源已经几乎消失了,冰川融化。8000万年,不断增长的人口每年令人担忧。十亿人口的睡眠每天饿了。几年后,大多是在贫穷国家,将会有超过二十亿人养活。根据1798年托马斯·马尔萨斯,世界人口增长速度比食物的供应,直到饥荒。疾病和战争会减少日益增长的人们的数量。

生育率下降已达到不同的国家在不同的时间但它首先到达法国。到19世纪晚期,法国的生育率已经降低到3个孩子每个妇女没有使用先进的避孕措施。直到启蒙运动,这一概念是,上帝决定孩子的数量,人们无法锻炼的。其他国家在西方被认为法国然后又破产感染的婴儿潮一代人口统计学家了警卫。

使悲哀的是,到2030年,历史上最大的一代青少年将达到生育年龄。如果每个女人只熊两个孩子甚至人口就会疯狂地生长。孟加拉国是最高最密集的国家,气候变化的威胁。卢旺达的另一个令人担忧的情况。贾雷德·戴蒙德在他的书中,崩溃,认为,在800000年800000年的卢旺达种族灭绝大屠杀的原因不仅仅是种族仇恨,但也随着人口的农民不得不相同数量的土地分成更小块,因为超过人口。

全球变暖可以是重要的考虑因素。根据布莱恩·奥尼尔的国家大气研究中心的,如果人口达到74亿年而不是89亿年到2050年,然后减少碳排放的15%。考虑到人口是唯一的问题是错误的。为了减少全球变暖,我们必须从化石燃料转向一些替代能源无论不断增长的人口。

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.
