Biosphere

into the limelight. The followers of the Green Perspective, the Greens, believe that human activities such as industrial activity, motor vehicle emissions, deforestation etc have led to environmental degradation causing issues like damaging the biosphere, lack of food to feed the ever-increasing population and extinction of a large number of wildlife species. In order to deal with these problems the Greens suggest that the number of harmful activities that are carried out by humans need to…

can be defined as a community of abiotic and biotic organisms interacting with their environment. All ecosystems function in a state of dynamic equilibrium which is the product of the interrelationship of the elements of an ecosystem: atmosphere, biosphere, hydrosphere and lithosphere. Ecosystems become at risk when they endure amounts of interactions and stress which exceed its carrying capacity. In order to counteract this, ecosystems must be managed effectively. Management can be broken down…

Only fifty years ago, exploring space would be a daunting task. These days, humanity is much more experienced in this endeavor with the multiple successful missions doing so. Space exploration is the traveling through the unknowns of space and the research of extraterrestrial bodies using spacecrafts. This includes sending both man and unmanned spacecrafts meant to observe and travel to planets and asteroids. Currently, we live at the dawn of a new space age powered by technological advancements…

biological and physical factors individually as well as collectively that compose the nature and man-made surroundings. Man is a part of environmental system. The environment consists of four components atmosphere, hydrosphere, lithosphere and biosphere. The temperature variation in these components is the basis of heat budget of the earth. While the elements (Carbon, Nitrogen, Phosphorus, Oxygen etc.) and compounds that sustain us cycle endlessly through living things and the environment.…

For my modern leader I chose Rachel Carson, I chose Rachel Carson because I wanted to know more about her what she did. Rachel Carson was born on May 27, 1907 in Springdale, Pennsylvania, Rachel Carson is considered a leader because Rachel Carson stayed true to her research when she faced with Critics and that her words inspired the environmental movement. On April 14, 1964 Rachel Carson died from breast cancer after 2 years of publishing her book "Silent Spring" when she was 56 in Silver Spring…

The snowball Earth Theory was hypothesized by British geologist Brian Harland in 1964. The core ideal of the theory is that during the Pre-Cambrian period, the continents of the Earth were located near the Southern Hemisphere, and the entire planet was covered in glacial ice sheets, from the Poles to the equator (Schrag, et al., 2002). The following essay will aim to explain the theory of the Snowball Earth in detail. Brian Harland based his theory on the fact that he found glacial tillites with…

a)The five most important biogeochemical cycles are the oxygen cycle, nitrogen cycle, carbon cycle, sulphur cycle and the sedentary cycle. These five cycles can be classified into pools. Active pools are free flowing cycles controlled by life processes such as photosynthesis. Storage pools are segregated bodies controlled by physical processes such as, volcanic eruptions or earthquakes. Oxygen cycles through the environment in three major forms; gaseous atomic oxygen, and the…

of the moon landing but a thousand times more spectacular. Imagine living on a planet light years away. To just get there, we would need an engine able to harness an unimaginable amount of energy, radiation shields, a spacecraft able to create a biosphere to sustain crop growth, and a way to recycle water. The invention of these items would alone be quite a phenomenon. To combine all these inventions would be a plethora of innovation. Colonization would be the achievement of…

The Survival of Beautiful Blue Planet Rachel Louise Carson was an American marine biologist and conservationist whose book Silent Spring and other writings are credited with advancing the global environmental movement. Rachel Carson mentioned in her book Silent Spring that “Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is something infinitely healing in the repeated refrains of nature - the assurance that dawn comes after…

Abundance: The Future is better than you think For every action there is a reaction, for every cause there is an effect. There’s always two sides of the coin, therefore in times of darkness, it can be easy to have an overwhelming desire to succumb to the darkness, but that is not the human spirit. Humans know how to survive and in order to address and overcome adversity, you have to believe that better exists or that more can be achieved. Technological innovations and inventions did not evolve…
