There are forests all over the world. The type of forest varies depending on the location of the forest: for example, there are tropical rain forests, coniferous forests, and deciduous forests. Slide 4: Forests occur naturally, but they can be affected positively and negatively by human behavior. If a forest is carefully replanted and allowed to grow, it can exist in balance. If the forest is cut down faster than it can grow back, then it will be used up quickly. Affects of Forest Slide 5: Forests serve as home to many of the organisms that live on the land. Forests are also very important because they are major contributors to recycling and cleaning the world supply of oxygen. Forests also provide wood, which is useful both as a construction material and as a fuel source. Importance Of Forest Slide 6: FOSSIL FUELS Slide 7: Fossil fuels take millions of years to form. They are the product of the fossilized remains of dead plants and animals that have been exposed to the heat and pressure deep within the earth’s crust. There are many types of fossil fuels, such as petroleum (gasoline), natural gas, and coal. Fossil Fuels Fossil Fuels: Source of energy : Fossil Fuels: Source of energy Fossil fuels are arguably one of the most valuable natural resources in modern times. It is estimated that 86 percent of the world’s energy comes directly from burning fossil fuels. Fossil fuels are the source of energy for almost every machine, including the generators that produce electric energy. Fossil Fuels: Affect Environment : Because fossil fuels take so long to form, they are being consumed faster than they can be produced. Fossil fuels are a major contributor to air pollution because when they are burned they release many dangerous gases such as nitrogen dioxide, methane, and carbon dioxide. Fossil Fuels: Affect Environment Slide 10: Solar Energy The sun is the closest star to Earth. It brings heat and light to the world. Some areas of the world, such as those closest to the equator, have more sun than others. Solar Energy : Solar Energy The sun shines naturally but it is not affected by human activity. It cannot be used up. However, its intensity varies with the seasons, and it is not available at night. Solar Energyuseful for plants : Solar Energyuseful for plants The sun’s rays are used for energy by organisms that undergo photosynthesis. Nearly every organism on the planet gets energy through photosynthesis, directly or indirectly. There are also ways that people can utilize the energy that the sun provides. Uses Solar Energy : Uses Solar Energy We can use solar power in simple (facing the sun to get warm, using greenhouses to grow food, etc.) and more complex (solar panels for heating) ways. Wind : Wind The wind blows naturally – it is not caused by human activity, and it cannot be used up. The power of the wind drives sailboats. It has been used to power windmills that grind grain. Windmills can also use the circular movement of the blades to turn a turbine. This is increasingly used as a means of generating electricity. Wind : Wind Wind power does not make greenhouse gas emissions. It does not directly cause pollution. However, critics of wind power say a large number of windmills could cause problems for animals, especially migratory birds. Some people think the windmills are unattractive. THINGS TO REMEBER : THINGS TO REMEBER A forest is an area with a lot of trees. Forests is a renewable resource, if we do Aforestation Forests can be used as an energy source by burning of wood as a fuel. Deforestation cause pollution; cutting down trees takes away animal homes and affects the oxygen in the world. Fossil fuels are the product of the fossilized remains of dead plants and animals that have been exposed to the heat and pressure. Fossil fuels are found deep within the earth’s crust. Fossil fuels are currently producing 86% of the world’s energy. Disadvantage of fossil fuels are They pollute the environment, they are not renewable. Solar energy comes from the sun. Solar energy is a renewable resources Uses of Solar Energy It can be used for warmth, for light, and via solar panels to generate electricity. Wind is caused by the uneven heating of the atmosphere Wind as energy sources: Wind can power windmills or power turbines to make electricity.
