(WhY) Some people claim that better technologies can increase the efficiency of extracting resource deposits from areas where resources have already been exhausted. (Do you believe on this statement) However, deposits will eventually become depleted, even with the use and development of better technology.  2 GUIDE QUESTIONS: 1. Do you practice these at home? If yes, list down the activities you do at home. 2. Why do you practice these at home? 3. Why are these important?  Over the last decades, the use of primary resources has been increased due to the growing global population, the improvement of economies, and a new lifestyle that is changing the habits of populations from high-income and developing countries. Questions: What is the impact of rising technology?  Today, the increasing population, together with the increasing demand for energy resources, has contributed greatly to the increasing energy consumption. Similarly, the rise in technology contributed to energy consumption. Increased energy used led to the exhaustion of energy sources. This may ultimately result in economic issues and problems such as 1. price increases (inflation), 2. economic stagnation, and 3. unemployment.  The United Nations World Commission on Environment and Development states: “sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Conservation ? Cogeneration ? Sustainability ?  Conservation - is a key factor in solving the energy crisis. Every individual’s action that requires a little sacrifice when taken collectively can save a lot of energy. It also provides several advantages, among them are as follows: a. reduction of cost of production b. reduction of inflation c. saving on consumers’ money d. slow depletion of nonrenewable fossil fuels e. reduction of environmental pollution, land disposal, and water disposal  Cogeneration is a process in which waste heat from industrial processes is captured, and used for useful purposes like electrical production, which can greatly help the energy situation. In other counties, like the United States, the process has increased energy efficiency from 80% to 90%. It is expected to supply about one-third of the country’s electrical needs. Consumption of energy resources depletes the supply of energy. It is about time that we break our habits. Changing lifestyle, recycling, and avoiding unwise consumption will certainly create changes.  Building sustainable energy systems by harnessing our indigenous sources of energy, like geothermal and biogas; solar and hydroelectric energy; wind energy; and diesel fuel from coconut oil and other trees; and charcoal or green charcoal just to name a few alternative energy resources that can meet the increasing demand of energy needs.  Sustainability is a method of harvesting or using a resource so that the resource will not be depleted or permanently damaged. The energy crisis has hit the Philippines so much. The increasing oil prices and its shortage propelled the country to adopt a ten-year energy plan in the 1970s.  APPROACHES IN SOLVING ENVIRONMENTAL PROBLEMS 1. bottom-up approach - which involves the change in attitudes and values which can influence a lifestyle change; 2. the top-down approach - which, involves the creation of laws and regulations to protect the environment; 3. crisis approach, - is believed that misfortune or disaster must first happen to bring about changes in the way people relate with the environment. According to studies, there is no single solution to solve environmental problems. 1. bottom-up approach, 2. the top-down approach, 3. the crisis approach, Different levels on which people can participate to bring about solutions to the problems of the environment. (5) Different levels on which people can participate to bring about solutions to the problems of the environment. 1. change in individual lifestyle, 2. Political involvement, 3. joining environmental organizations 4. actively participating in environmental programs and projects, 5. and choosing careers related to environmental protection. “ everyone wants a better place to live. Some people want better homes and housing, while other people want better schools, more jobs, better shops, or cleaner and safer streets” 3 issues people need:  3 issues people need: a better environment – that means green spaces, play areas, no litter, nice gardens, decent houses, less noise, and pollution. The resources used should renew over generations.  3 issues people need: a better economic growth – that means jobs, affordable prices, lower electricity, no swindlers.  3 issues people need: better social living conditions – that means good vacation facilities, lots of community groups offering sports and arts, and sociable neighbors. End…. SUMMATIVE TEST TOMORROW
