What Is Environmental Degradation? Environmental degradation is a result of socio-economical‚ technological and institutional activities. Degradation occurs when Earth’s natural resources are depleted. These resources which are affected include: • Water • Air • Soil The degradation also impacts our: • Wildlife • Plants • Animals • Micro-organisms How Environmental Degradation Occurs Environmental changes are based on many factors including: • Urbanization • Population growth • Economic

crude prices further. Effects of increased oil price; It is not just oil prices that rise. The cost of food rises as well‚ partly because oil is used in many ways in growing and transporting food and partly because of the competition from biofuels for land‚ sending land prices up. The cost of shipping goods of all types rises‚ since oil is used in nearly all methods of transports. The cost of materials that are made from oil‚ such as asphalt and chemical products‚ also rises. If the cost

Microorganisms are tiny‚ small living things which can not be seen with eyes. They spread everywhere around the world. Most people think that microorganisms are harmful to the environment. Humans exploit these small living things hundreds of years ago. Science has developed and scientists have established new science related to microorganisms‚ it is called microbiology. In this essay‚ I will talk about one of the oldest and most widespread microorganisms in our planet‚ bacteria. Bacteria lives everywhere

The Human Genome Project (HGP) was one of the great feats of exploration in history - an inward voyage of discovery rather than an outward exploration of the planet or the cosmos; an international research effort to sequence and map all of the genes - together known as the genome - of members of our species‚ Homo sapiens. The Human Genome Project was started in 1990 with the goal of sequencing and identifying all three billion chemical units in the human genetic instruction set‚ finding the genetic

The sugarcane undergoing fermentation produced a volume of carbon dioxide that was nearly nine times more than the corn‚ wheat grain and wheat stalk. Wheat grain and corn was nearly doubled that of the wheat stalk and the control (Figure 1). Sugarcane was the leading plant material producing the highest volume of carbon dioxide (mean= 19.9 ± 0.996 mL) while other than the control; the wheat stalk produced the lowest volume of carbon dioxide (mean= 1.33 ± 0.036 mL). As time elapsed‚ the sugarcane
