Ecology is derived from the Greek words oikos meaning home and logos meaning knowledge. In 1866, German biologist Ernst Haeckel defined Ecology as, "the comprehensive science of the relationship of the organism to the environment” (Wikipedia). Because it is the study of relationships between all forms of life on our planet and the environment, ecology encompasses Earth entirely. Since ancient times, nature has served us by giving us everything we need from the air we breathe, to the food we eat, to the water we drink, to the wood we use to build and fuel our home. For thousands of years, people have coexisted in harmony with the environment and it seemed to them that the resources of nature had no end or limit.
However, from the industrial revolution era (1760-1840) to modern-day times (2014), human influence on Earth has begun to move in a negative direction. Metropolises with thousands of steaming, polluting industries and plants can be easily located all over the world. The byproducts of a factory’s activity pollute the air we breathe, the water we drink, and the fields where our crops are grown. For this reason, those who live in cities prefer spending their holidays far away from the city noises and instead, closer to nature. Perhaps they like to breathe fresh air or to swim in clear water because the ecology is not so poor as in the cities. For several centuries, humans have created many complex ecological proble...

...esertified or is threatened by desertification.
Because of the rising human population growth rates today, we encounter numerous amounts of ecological challenges that should be addressed for reform. Three simple methods that we can use for our own individual accounts are to reduce, reuse, and recycle (Environmental Science for AP). The key part of waste reduction is conservation – using natural resources wisely and using less than what you think you “need” can avoid any excess waste. By reusing materials in their original form instead of throwing them away or passing those materials onto others, one man’s trash becomes another man’s treasure. Everything we create is of some value to someone. If reducing and reusing do not fit the criteria of one’s needs, recycling is also an option because the item can be transformed into the same item or modified into a new product.

- As the world population grows at an astonishing rate, our mother earth is getting very crowded. Our natural resources are being overused and the land available for life is getting smaller and smaller. Farmers have to find ways to make what land they have usable and profitable. Farmers in general are a shrinking population. How does this relate to the general public. Without farmers we would not have food, without food we will all die. The world is realizing this problem and the best way to solve it is to find more land for habitat.... [tags: Environment Mars Planet Life Essays Papers]

- The tremendous impact that oceans have on our planet engender how we live our lives on this earth. In this respect, we can agree that our lives depend on oceans and their many contributions to the earths environmental services. The oceans are a part of what make our planet different from any other planet in the solar system. Incidentally, oceans take up more than two thirds of the total world; other than giving us a form of outdoor recreation many people seek out the ecosystem services by visiting the beach it is a place where people utilize the invaluable aesthetic and spiritual value of the ocean....

- The thesis of these excerpts from Bill McKibben’s book, Earth: Making Life on a Tough New Planet, is that humanity has permanently changed the earth through global warming. This idea relies on the assumptions that global warming has caused irrevocable changes to the environment and that humans have only recently changed the earth. One key premise that these excerpts rely on is the idea that the changes caused by global warming are irreversible. McKibben argues that we have gone past the point where even drastic changes to how we live couldn’t prevent the worsening of global warming.... [tags: humanity, environment, irreversible, nature]

- “The Earth provides enough to satisfy every man 's needs, but not every man 's greed” was rightfully said by Mahatma Gandhi. The current economic and environmental issues have caused me to take action in educating myself fully in the matter of environment and society. I began my day without waste, with the mentality of that of an environmental sociologist, truly reflecting on the fact that society and environment are interrelated. The challenge of going a full 24 hours without disposing of anything at all was one that I accepted with whole heartedness.... [tags: Natural environment, Environment, Recycling]

- Passing of the years, development and growth of the planet have been guided to create and produce new things to satisfy human needs with industrialization and modernization regardless the consequences that occurred in the environment. Once, the environment was evaluated, and analysed the impact of people in it, all the effects were vast, for example weakening of the ozone layer, acid rain, decreased natural resources like water, the exploitation of natural resources, effects on air quality, contamination of rivers, deforestation; we realize the damage, we 've been defiling our planet and therefore our quality of life....

- Joel E. Cohen once stated in his How Many People Can the Earth Support?, “A little boy wanted to know the sum of one plus one. First he asked a physicist, who said, “If one is matter, and the other is antimatter, then the answer is zero. But if one is a critical mass of uranium and the other is a critical mass of uranium, then that's an explosive question.” Unenlightened, the little boy asked a biologist. She said, “Are we talking bacteria, mice or whales. And for how long?” In desperation, the boy hired an accountant.... [tags: Environment ]

- The possibility of extraterrestrial life is a phenomenon that has grasped society for a millenia. Many past societies have asked the question ‘Are we alone?’ Today, some people believe that many ancient formations could have been made with help from outer space visitors, such as the Nazca Lines in Peru, Stonehenge in Great Britain, or the Pyramids. While these are mysterious, most agree that they were not made by little green men. What scientists of this era wonder is not whether there is life out there, but where it could be found and in what form.... [tags: Extraterrestrial life, Extrasolar planet, SETI]

The distinction between living and non-living isn 't as easy as sixth grade science class made it seem, yes there is energy and matter involved in life but scientist in our world have not come in contact with a certain definition for life, but they have made some characteristics regrading a living organism. For example, they can react to their environment and heal themselves when damaged, next they can grow by taking in nourishment from their surround environment and process it into energy, also they can reproduce passing along their traits and characteristics to their offspring,...

For example, if scientists believed a signal came from Mars, an expensive rover would travel to the Red Planet, and not find anything. Some people believe the risk of looking for extraterrestrial life is too high, because of false alarms that would be an obstacle faced during the research process. Due to potential economic consequences, people believe the search for extraterrestrial life should not continue.... [tags: life on other planets, ineffective technology]
