greenhouse gases, like carbon and methane, in the atmosphere. The carbon cycle utilizes sinks and reservoirs to balance the amount of carbon in the air. A source of carbon dioxide is the burning of fossil fuels, which is being balanced by the photosynthesis of plants. The carbon from burning excessive amounts of fossil fuels is absorbed by trees in the environment. These fossil fuels include oil, coal, and natural gas. When burned, they emit carbon and release it into the air. Humans have been burning
project on ecosystems briefly describes its’ concept and illustrates how ecosystem considerations change daily our decisions, and why is this behaviour change is important. Acknowledgement: This interesting project has given me a chance to realise the importance of ecosystem and made me study the topic in detail and understand it better. I will like to thank my Biology teacher (Ms. Xxxxxxxxx) for giving this project
decrease the amount of deforestation. Everyone needs to be educated on the harmful effects of deforestation also on the importance of population control which will reduce the number of trees that need to be cut down for human needs. Whenever a tree is cut down we should replant another in place of the one that was harvested. Also, we should join together in understanding the importance of recycling, avoid wasting papers and the unnecessary use of paper towels and paper
The Cambrian period is the first geological period of the Paleozoic Era which was about 56 million years from the end of the prior Precambrian to the beginning of the Ordovician Period. The Cambrian period is the beginning of a large difference in life on Earth. Before the Cambrian most of the life was very simple and unicellular. For the first time we began to see more multicellular forms of life. "The oceans became oxygenated. Although there was a lot of atmospheric oxygen by the beginning of
The increased focus on maritime security post 9/11 has inadvertently put SLOC like the IO on the radars of many observers for fear of disruption to shipping and trade. For starters, the threat of piracy, especially along the waters near the Horn of Africa and in the northern part of the Straits of Malacca, continues to be a bane to merchant ships. The busy shipping traffic in the IO naturally attracts the attention of pirates keen to grab the cargo, and even the vessels and the valuables carried
Biological resources provided by the Earth play essential role in economic and social development of the humans. Therefore, it is of great importance to acknowledge an enormous value of biological diversity both to present and future generations. However, ecosystems and species have never been under such threat as they are nowadays. Loss of species caused by human activities continues at an alarming rate (CBD, 2014). As a reaction to the seriousness of the problem, in November 1988 the United Nations
plants. The process is mainly characterized by the visual symptoms as the loss of chlorophyll and other pigments, colour change, dessication and abscission. Cellular and molecular events contributing to these visual symptoms include cessation of photosynthesis, disintegration of organelle structures, intensive degradation of chlorophyll, loss of
events also allow algae and bacteria to grow on the upper layers of the ocean, forming a shield on the ocean which blocks sunlight. As the sunlight would not be able to reach the deeper zones of the oceans anymore, marine plants cannot survive as photosynthesis is not possible without the energy from sunlight. This does not only cause the extinction of these flora, but also the fauna that feeds from these plants. Moreover, in the case of euxinia, the anoxic events might even have led to the poisoning
sound. We pray to air God. Ancient Indians, therefore, emphasized that the unpolluted, pure air is source of good health, happiness and long life. Vayu god is prayed to blow with its medicinal qualities’ . The Atharvaveda also mentions about the importance of air, water and green plants essential for human existence. Although there was as such no concept of the word “Pollution” during the vedic era but it was referred as the term “Poisoning” of environment. The A.V. 18.17 recalls that three things
Introduction Climate is usually defined as the average weather in a place. It includes patterns of temperature, precipitation (rain or snow), humidity, wind and seasons. Climate change is a change in the statistical properties of the climate change system that persist for several decades or longer-usually at least 30 years. The statistical properties include averages, variability and extremes. Climate change, also called global warming, refers to the rise in average surface temperatures on Earth
