This chapter to me was all about organisms that can survive in extreme conditions. How every square inch of earth is inhabited with creatures of one kind or another. I learnt the fundamental principle of biological geography, that wherever there is liquid water (h2o), organic molecules, and an energy source, there is life. I found out about the McMurdo Dry Valleys of Antarctica, who soils are the coldest, driest, and most nutritionally deficient in the world. How some specialized species of bacteria and archaeans live in the walls of volcanic hydrothermal vents on the ocean floor, where they can multiply in water close to or above the boiling point. He also describes an organism called, hyperthermophiles, that love extreme heat, and Deinococcus radiodurans, a microorganism which can withstand levels of radiation capable of killing humans and other organisms.
The McMurdo Dry Valleys of Antarctica seems from its description sterile and desolate. When I read the quote from Robert F. Scott in 1903, the first to explore the region, “ We have seen no living thing, not even a moss or lichen; all that we did find, far inland among the moraine heaps, was the skeleton of a Weddell seal, and how that came there is beyond guessing.” The skeleton of the Weddell seal made me thing that maybe it was once a ocean and dried up over the years. But then again it is Antarctica, maybe it was trapped in a glacier, when it melt and retreated, it left the skeleton behind. It was shocking to find out that only twenty species of photosynthetic bacteria, which is making a long story short, mostly single-celled algae and weird, nasty sounding microscopic invertebrate animals that feed on these primary producers. These organisms of this region are what scie...

Scientific terms are used frequently through out the text, but are followed by explanations in a coherent way, hence it makes it clearer and more understandable to the reader. For example, she is writing about substances and their characteristics, one of them is an unusual term called “half-life”, followed by an explanation in a parenthesis with a clearer explanation of the term. That way, it can be understood by the general public. The writing is straight forward and it’s absent of metaphors and similes. It is more an informative reading rather than descriptive, therefore it is lacking details and adjectives.

Now, sustainable development and quality of life are crucial to the well being of our nation. Thus, I have pondered many a year on this very important matter and have consulted a very knowing Canadian of my acquaintance at the World Wildlife Fund (WWF). The amount of natural resources in this country being usually reckoned infi...

Because of human and nonhuman connections to specific places including knowledge, experience and community, using a sense of place and permanence as a green transnational multilateral initiative could be a successful step towards green democracy and ecological citizenship. Robyn Eckersley offers the suggestion of a constitutionally entrenched principle that would enhance ecological and social responsibility: the precautionary principle. I suggest connecting localized, place-specific boundaries with the principle. This addition is meant to aid in fostering ecological citizenship, expanding the moral community, and creating a responsible society. This addition would also be meant to unite a transnational issue that all nations could agree upon. This would create a binding multilateral principle that would be thoroughly accepting of specific ecological needs and characteristics of specific places.
There is no hesitation when it comes to whether humans impact the global environment. However, it is questioned in whether human’s ecological footprint is either negatively or positively impacting. In clear perspective, humans share from both sides and their ecological footprint is noted towards whether it will benefit or harm the environment around them. Topics such as overpopulation, pollution, biomagnification, and deforestation are all human impacted and can harm the environment, but some include benefits into helping the world around us with solutions to their problems.

Every day the world around us is changing ever so slightly in many different ways. Humans can affect the environment through our day to day lifestyle without even noticing the change. An ecological footprint is a measurement of how much a person uses the environment around them to live their life. This given measurement can help one to see their impact on the earth. It is an important tool to understand what actually a human does to change the habitat near them. My ecological footprint results gave me a perspective of how my daily life can impact the world I live in, as well as, how I as an individual can change my actions to make less waste on earth. It is also useful for each person to know their own ecological footprint since no one live
This approach to development rejects the idea that development aims simply at the fulfilling of basic needs, such as food and shelter. It argues, on the basis of human solidarity, that all people should be involved in the integral and authentic development of all. Development, in this sense, gives attention to economic justice, ecological sustainability, and other values that go beyond speaking of development only in terms of economic growth. This ecological sustainability begins with relationships taking place at the atomic and molecular level, between plants and animals, and among species in ecological networks and systems. For example, he points out, “We need only recall how ecosystems interact in dispersing carbon dioxide, purifying water, controlling illnesses and epidemics, forming soil, breaking down waste, and in many other ways which we overlook or simply do not know about”
Are you aware of the detrimental impacts that we have had on our environment? Every second, the Earth is being polluted by poisonous gases, waste products and due to human activities, the world’s climate is dramatically changing. In other words, these impacts do not only harm our environment but also our health. It has been scientifically proven that air pollution causes respiratory diseases and cancer, due to the inhalation of all the harmful chemicals. Water pollution can also lead to typhoid, diarrheal diseases and other waterborne disease, due to the intake of bacteria and parasites. Many people have died due to these health-related illnesses. So why are we still living in this awful condition? Air sustains us and water is a basic necessity, so we should do what we can to prevent pollution. In short, we should protect our environment to ensure a healthy life a...
