The greenhouse effect has lately become a hot issue on the planet. Heavy industries and manufacturing have caused the atmosphere of Earth to become an almost solid layer that does not reflect the solar radiation back in space. With the proliferation of cars and other internal combustion vehicles, this layer is growing and getting denser. And instead of reflecting approximately 30% of the solar energy, the dirty atmosphere reflects it back to surface of Earth, increasing the average temperature on Earth. Since greenhouse effect was discovered, the average temperature of Earth surface increased by 90 degrees. Thus, human activity is slowly frying the planet.
Industrialization and urbanization has led to massive destruction of virginal nature areas. Building cities means destroying nature. Even though construction designers and workers plan to preserve nature, still the water, soil, and air are contaminated by the waste from urban areas. As nature gets more contaminated, the harmony of the fragile ecosystems
