We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas.

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

Blood donation: The most valued service to mankind

Millions of people owe their lives to people whom they will never know or meet in their lifetime. They are none other than those people, who have donated their blood freely and without any reward - voluntary blood donors. Voluntary unpaid donors are the foundation of a safe blood supply which saves millions of human beings from the death.

Nothing is comparable to the preciousness of human blood. In spite of the rapid and remarkable conquests of medical science today, there is no laboratory that manufactures blood. It is only in human beings that human blood is made and circulated. For those who require blood for saving their lives, sharing from other people is the only means. Therefore, voluntary donation is the only way of accumulating blood at safe storage to meet emergency requirements for saving lives. Blood is required for treatment of accidental injuries, burns... In times of accidental injuries that shed huge amounts of blood and also in various types of surgical operations for medical treatments, we require blood for transfusion. Unavailability of blood may cost lives. Therefore, importance of blood donation is tremendous. This is the greatest gift one can give to the humans. Voluntary blood donors are saviors of mankind. If someone really loves oneself and other fellow beings, the only way to express it is to donate blood voluntarily.

Blood donation is harmless and safe in the body. Rather, it is a social responsibility. The donor is donating for it as it will be used in saving lives of his fellow beings. He himself may use the same during his own need. So, today's donor may be tomorrow's recipient. Without their humane gifts of noble donors, that also from the heart, many lives might have lost for want of blood. Therefore, the most generous and biggest ever contribution to mankind is blood donation.

Blood donation can save millions of human beings from the death.

A. True

B. False
