They all based on the cells, which is the fundamental structure of lives. The inner chemicals are still the same and they react alike use and covert energy.

Profound concept of biology

4 panels, bacteria

All creatures are related to each other

DNA / RNA is to record and transmit genetic information 23% from each parent Same chemical

3.International environmental law


大致说的是环境法在英国不是一个新法律,因为在查理二世时候为了克制烟尘污染类似发来已经颁布了,但是那时立法不够严谨所以没什么效果;工业革命时候,政府加大立法制度,原因是克制那些用Adam Smith理论提高利益迫害工人和污染环境的奸商。

因为现在short of talent,各个公司和国家都在争抢talent people。有一些young immigrants 上 university 去读书,然后就移民了。毕业后,他们就和 local 学生争 抢进一些公司(给了数据),但是其实国家也是通过这样的方式来吸引人才;同时 国家和其他 organization 应该把 talent 放在 primary 的位置上。

原因一change of the nature of economy lead to increasing in talent demand

原因二decreased population causes less skilled workers supply




Evidence shows that deficiency of talents in exacerbates. The demand talents bloomed tripled in contemporary companies, global demography contributed to labor lacking

the aging of baby-boomer generation also distract numerous experienced employees from working as well.

Developing countries undergo similar situation while dealing with culture legacy that impedes development.
