Spain was once the World’s most powerful country. By the 20th century it was a poor and backward country where corruption was rife. It had lost nearly all of its overseas possessions (e.g. Cuba, the Philippines) and great extremes of wealth and poverty caused severe social tensions. Industry was confined mainly to Barcelona and the Basque country. Spaniards were divided on the type of government that they wanted. Monarchists were conservative and Catholics and did not want to reform Spain. Those who wanted a republic were anti-clerical and hoped to reform Spanish society.

More than 3000 children die each day due to contaminated water.
More than a quarter of children under 5 years of age die from unhealthy environments. Every year, environmental hazards - such as indoor and outdoor air pollution, secondhand smoke, unsafe water, lack of sanitation and inadequate sanitation - kill 1.7 million children under the age of 5. , according to two new WHO reports.
First report, Inheriting a Sustainable World: Atlas of Child Health and the Environment shows many of the most common causes of death among children 1 month to 5 years old - diarrhea, malaria and pneumonia – can be prevented with interventions that reduce environmental risks, such as access to clean drinking water and cooking fuels.
