Mass extinction events may be the result of multiple ecosystem stresses that reach the level where the ecosystem unravels. Other than the meteor impact that destroyed the dinosaurs, the rest of the mass extinctions seem to have multiple contributing causes, and each one ultimately had an energy impact on life processes. The processes can be complex and scientists are only beginning to understand them. This essay will survey mass extinction events and their aftermaths in some detail, as they were critical junctures in the journey of life on Earth.
and noted that Eurasia was spread along an east-west axis, while Africa and the Americas were north-south, which made Old World diffusion easier, but that idea also has problems, as Fertile Crescent crops did not spread to East Asia due to rainfall timing differences (winter rains in the west and summer monsoons in the east). Mesoamerican and Andean civilizations had dramatic geographic limitations, which was their greatest contrast with Eurasian civilizations. However, like the migration of or the exchange when , it was easier for cultural innovations to spread along the same latitude, as they would move through similar biomes. North-south diffusion is far more difficult, as it moves through different biomes, such as tropical forests and . Eurasia's geography was more conducive to communicating innovations, which made it more cosmopolitan than sub-Saharan Africa or the Americas, which helped them technologically advance at a faster pace. Isolated peoples are usually culturally and technologically backward compared to nearby peoples who are more cosmopolitan, and people isolated by mountainous geography, such as those of the Scottish Highlands, Balkans, Appalachia, and Southeast Asia were relatively primitive compared to those around them. and are classic instances of isolated peoples keeping their cultures intact, which provided a window into the human past, but their cultures also did not "progress," which included their technology.

This essay is intended to draw a comprehensive picture of life on Earth, the human journey, and energy's role. The references that support this essay are usually to works written for non-scientists or those of modest academic achievement so that non-scientists can study the same works without needing specialized scientific training. I am trying to in a tiny fraction of the global population. . My hope is that the energy issue can become that tiny fraction's focus. Properly educated, that group might be able to help catalyze an energy effort that can overcome the obstacles. That envisioned group may help humanity in many ways, but my primary goal is manifesting those technologies in the public sphere in a way that nobody risks life or livelihood. I have seen too many wrecked and prematurely ended lives (, ) and plan to avoid those fates, for both myself and the group’s members.

Really appreciate the way you are helping people to get prepared for their IELTS. Your video lessons are really thoughtful and well prepared. Just one question on a subject essay; the topic called for the perspective of people, competing for a job, with skills or without skills but having an education. Whereas, in your essay, the second argument is about business as a good fit for people with no formal education. How do you see it, are you not going away from the topic?

In today’s world, more and more students are opting for studying in a university. The completion of university education is an important milestone for them. While many believe that the sole purpose of university education is to increase job prospects for graduates, others are of the opinion that individuals and societies benefit in broader ways from it. In this essay, both sides of this debate will be analyzed before a reasoned conclusion is drawn.
On the one hand, most people think that studying in a university increases a student’s chances of securing better jobs. As an illustration, almost all educational institutions have placement committees that schedule campus interviews and invite the top organizations to visit their colleges and select students for job placements in their companies. Such hiring of graduates improves their future career prospects. Thus, it is understandable why this point of view has garnered support.
On the other hand, there are individuals who believe that university education has other advantages. For instance, almost all students have to live away from home, in a college hostel, to complete their course in a university. This develops independence, confidence and socialism in the students. As a result, they grow up to be more mature human beings. In addition, university programmes improves the intellect of students and countries can prosper from the contribution such graduates can make to the society. Therefore, it is clear why some people support this point of view.
The above discussion puts forth several convincing arguments for both sides of the debate. However, after analyzing these two points of view, it is unambiguous that university education is a precursor to a better job and a fulfilling career. It is therefore expected that more and more students complete university to enhance their job opportunities.
