social media by young Australians has become increasingly popular. This essay will show that social media can have many benefits to young Australians by enabling them to engage with peers‚ the creativeness it brings out and enhanced learning opportunities. Cyber bullying and privacy issues are some of the challenges that can arise with the use of social media. One of the benefits of social media is the ability to connect and engage with others. Keeping in touch with friends and family who live far

Threats to Biodiversity: Habitat loss is mainly due to human population growth‚ industrialization and changes in the land use patterns‚ poaching of wild life and man wildlife conflicts. Man has begin to overuse or misuse most of these natural ecosystems. Due to unsustainable resource-use‚ once productive forests and grasslands have been turned into deserts and wastelands have increased all over world. Scientists have estimated that human activities are likely to eliminate approximately 10 million

Hydraulics – CIVL 2130 Conservation of Energy Aim The aim of this lab experiment is to observe the flow behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies

Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

THE VALUE OF NATURAL ECOSYSTEMS The most important of the inherent values of natural ecosystems is that they contain within themselves creative powers‚ which‚ over large spans of time‚ have produced the stupendous array of biodiversity the world over. The presence of a species and the things that it can do have a powerful bearing on shaping the environment of all. Organisms help to make the world and then it makes them. Humans are among the most complex of the achievements of the natural forces

Renewable Energy is Best Michelle Johnson HUM/111 March 26‚ 2011 L. Flemister Renewable Energy is best America’s dependency on foreign oil is costing us more than just money; it costs us our clean air and potentially thousands of jobs in America. Our nation needs to create its own renewable energy. The dependency on other countries is crippling our economy. Drilling for oil in the United States is not the answer. We need to take better care of our planet and that each of us must

wildlife conservation on campus. After observing 12 different stops on a three-mile long trip of Putah Creek‚ the average score I calculated as part of the university’s sustainability program is 1.83 on a scale of zero to three. This is a score that I expected from a university dedicated to sustainability and conservation‚ but there is room for improvement. In order to improve this score and balance high/low scores the university should have some areas reserved strictly for wildlife conservation (off
