On the local and regional levels, air pollution creates various types of problems against living and non- living environment. In the living environment it causes different types of physical, physiological and mental diseases.
Ocean is a vast natural resource of water. These have also been examined in the search for alternate sources of energy-generation. For example, gravitational pull, by sun and moon causes tides, in which sea level rises and falls, two times in 24 hours.

People who suffer from hunger remain undernourished. They don’t get enough food to eat. As such they don’t get energy, they need to live active lives.

The dry weight of organic matter produced by plants, their derivatives and wastes are called as BIOMASS. The biomass includes crop residues, plant parts, body parts of dead animals and animal wastes. As biomass is created due to photosynthesis by plants, so energy from biomass or bio wastes is regarded as another form of solar energy.
