Cars should be banned in city centers Nowadays, most of the people have their own car. Most of them say that they can´t live without it.Many environmentalists opinion is that cars should be banned in city centers. I support this view for a variety of reasons. First and the most important thing is the pollution. Using cars increase the level of pollution in big city centers. This is especially important because town centers always consist of tall buildings and narrow streets which often hold the pollution in one spot.Global warming is big problem all around the world. So, people should use
Diseases such as bronchitis, lung cancer, and heart disease may all eventually appear in people exposed to air pollution. Air pollutants such as ozone, nitrogen oxides, and sulfur dioxide also have harmful effects on natural ecosystems. They can kill plants and trees by destroying their leaves, and can kill animals, especially fish in highly polluted rivers. SOLUTIONS Air pollution has many disastrous effects that need to be curbed. In order to accomplish this, governments, scientists and environmentalists are using or testing a variety of methods aimed at reducing pollution. There are two main types of pollution control. Input control involves preventing a problem before it occurs, or at least limiting the effects the process will produce. Five major input control methods exist. People may try to restrict population growth, use less energy, improve energy efficiency, reduce waste, and move to non-polluting renewable forms of energy production
rain and its dangerous effects. The levels of acid rain vary from region to region. In Third World nations without pollution restrictions, acid rain tends to be very high. In EasternEurope, China, and the Soviet Union, acid rain levels have also risen greatly. However, because acid rain can move about so easily, the problem is definitely a global one. Global warming Global warming, also known as the greenhouse effect, immediately received international attention. Scientists, environmentalists, and governments around the world took an interest in the subject. Global warming is called the greenhouse effect because the gases that are gathering above the earth make the planet comparable to a greenhouse. By trapping heat near the surface of the earth, the greenhouse effect is warming the planet and threatening the environment. Many scientists criticized Mr. Hansen's report, and the debate over global warming continues today.
Aboriginal culture. From this deep and intricate understanding of their environment, Aboriginal Australians have developed many plant and animal based medicines. Land was spiritual, but also an economic resource as it provided the people with food, sources of wood, fibre and glue for making spears, utensils and other implements. However the people respected these aspects of their land and were environmentalists in the sense of 'taking care' of the land through their practices of performing increase ceremonies, 8 singing 'Song lines' and relationships with flora and fauna through a system of totemic relationships. Aboriginal people were social beings as they lived and gathered together in family groups . Their camps were comprised of a number of gunyas (bark huts), but the people also lived in caves or in the open air
economic operation all of the available output must be taken when it is available, and other resources, such as hydroelectricity, must be used to match supply with demand. Large scale wind farms are typically connected to the local electric power transmission network, with smaller turbines being used to provide electricity to isolated locations. Utility companies increasingly buy back surplus electricity produced by small domestic turbines. Wind energy as a power source is favoured by many environmentalists as an alternative to fossil fuels, as it is plentiful, renewable, widely distributed, clean, and produces lower greenhouse gas emissions, although the construction of wind farms is not universally welcomed due to their visual impact and other effects on the environment. The intermittency of wind seldom creates problems when using wind power to supply a low proportion of total demand. Where wind is to be used for a moderate fraction of
