1. The use of wind turbines does not generate pollution or radioactive waste like most other forms of electricity generation do.
2. Wind power may be used to provide electricity to individual homes or other facilities on a self-reliant basis, with no need for fuel or other materials to be supplied. If a natural disaster severs power lines, residents with windmills will not lose their supply of electricity.
3. Wind can also generate power for large numbers of people, using larger turbines connected to an electrical grid. This allows individuals to take advantage of some of their benefits without personally owning or maintaining the equipment.

Rainbows are circular because raindrops are spherical. When light from the Sun enters a raindrop it is largely reflected back inside a cone with a half-angle of 42 degrees. The reflected light is strongest along the surface of this cone where it is broken up into a spectrum of colours. When we see a rainbow we are looking at those drops from which the light along the surface of the cone enters our eyes. Consequently, a line from the Sun through our head passes through the centre of the circular rainbow. The angle between this line and any point on the rainbow is about 42 degrees.

A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases.

Many people in our country still do not have an access to proper sanitation facilities. They defecate in the open, on dry riverbeds, on railway tracks, near fields and many a time directly in water.
Poor sanitation and contaminated drinking water is the cause of a large number of diseases. Untreated human excreta is a health hazard and cause water pollution and soil pollution. When both the surface water and groundwater get polluted it becomes the most common route for water borne diseases like cholera, typhoid, polio, meningitis, hepatitis and dysentery.
