Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water poll
The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)).

THE CAPITALIST NIGER Chika Onyeani ………………………Every African must internalise this book - period….DAA INTRODUCTION In October 1960, Nigeria received its independence from Britain. By then, Ghana the former Gold Coast had been independent for three years under the great Osagyefo Kwame Nkumah. It was a time for celebrating Africa’s coming of age, as more and more African countries received their independence either from Britain or France. It was especially a poignant time for Africa, as then British Prime Minister Harold McMillan articulated his now famous “winds of change” sweeping Africa. We had high hopes for Africa, for the Black race, that the insidious imposition of foreign rule on us, the looting of Africa’s natural resources by our colonial masters accorded us would be things of history. That is more than forty years ago. Unfortunately, the promise of independence has not been fulfilled. Today, Africa has become more desolate; there is more starvation
Margit Tepner k0848752 Sustainability aspects of biofuels 1. Introduction The literature review will discuss the sustainability aspects of biofuels. Food production will be the main concern as it is the most debated issue, but other aspects, such as land use change and water consumption will be also considered as they are essential aspects in the biofuels sustainability criteria. The review will discuss the viability of biofuels based on the current technologies. Second-generation biofuels are not yet commercially viable and therefore will not be discussed; although they could significantly improve the sustainability of biofuels when they break through to the industrial scale. 2. The scale of biofuels production 2.1. Drivers of biofuels production Lal (2010) stated that "three inter-connected challenges face humankind in the 21st century": food security, climate change, and energy security. The world population is projected to reach 9 billion in 205

ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil
