Human uses of energy over 10‚000 years are explained in Changing Environments (Morris et al‚ 2003a). Until 10‚000 years ago humans lived as hunter gatherers in small groups‚ this changed in the current interglacial stage or Holocene with the introduction of agriculture. Figure 2.19 page 82 of (Morris et al‚ 2003b) indicates that during the early agriculturalist period humans had begun to domesticate animals that could be used for carrying and pulling.

Finances It is debatable whether or not technology is financially a disadvantage or advantage. On one hand‚ technology is cost effective‚ according to Small Business Bible---technology may boost revenue and profit through increased efficiency‚ productivity and limited man hours.

Memory makes us who we are. According to How Human Memory Works‚ most people talk about their memory like a thing they have‚ but memory doesn’t exist like your body does. It’s more like a concept that refers to the process of remembering. Many scientists and researchers compare the human memory as a filing cabinet with memory folders or a supercomputer in the past‚ but now people say that the average human memory is a much more complex system; memory is said to be a brain-wide process‚ not just in

conceivable that we world citizens of the twentieth century are not the only living beings of our kind in the cosmos. Because no alienspar from another planet is on display in a museum for us to visit‚ the answer‚ "our earth is the only planet with human beings‚" still seems to be legitimate and convincing. But that is a very narrow-minded way to look at things. The idea that life can flourish only under terrestrial conditions has been made obsolete by research. It is a mistake to believe that life

Overall‚ I agree with the message of the Human Being‚ Human Nature reading. I believe that at our core‚ we want to do good. We want to help others‚ find success and be the best version of ourselves that we can be; we seek to “do the right thing‚ the best we can”.

How can one believe that humans are innately altruistic‚ when humans are the only species that selfishly keeps other creatures in captivity for their own happiness and maliciously murders organisms for their own pleasure and desire to prove that their beliefs are correct? Although people can show sympathy for others‚ people are innately self-centered because humans are motivated by their fears and desire to surpass everyone else‚ so they can have the most. Although humans naturally want to obtain
