Honors Environmental Science

Video is basically about the history of Earth. Earth is very special planet because liquid water and oxygen exists. The video shows the relationship of oxygen and formation of life. After the single cell organisms, complex form of life started to appeared about 580,000 years ago. I was also impressed that how earth keep the balance of temperature and carbon level it self. Because the video was about why earth is habitable, characteristics and life forms, I was curious about what can be the risk element of human in 21 th century. Whenever an organisms overcome harsh conditions over the time, they achieved evolution. If severe natural disaster occurred on the earth and only few people survived, what biological evolution that human can achieve?
