Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.

Also, waste is dumped anywhere, even in the city where many people are living. The second pollution problem is sea pollution.
