Attempting to dig a pit would have been toilsome and ultimately fruitless. Fortunately‚ while on a fieldtrip‚ my classmates and I came upon an archaeological dig site. It was basically a big pit‚ about five feet deep‚ that was perfect for our observations. There were obvious changes in the soil through the different levels‚ and the archaeologist on location provided

Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants We all live on earth which‚ is but a planet‚ – and the only planet known to have an environment

The causes of pollution Pollution is the release of harmful environmental contaminants. The main air pollutants are carbon monoxide‚ lead oxides‚ sulfur dioxide and nitrogen oxides. The principle causes of pollution are exhaust pipes from motor vehicles‚ smoke released by factories and moreover‚ industrial plants burn coal and oil‚ which contain sulfur. New inventions and processes have been continuously developed to improve our way of life; such developments are called technological

Essay 1 Air Pollution: Causes and Effects It keeps us alive but at the same time‚ it can also be harmful. We breathe air everyday. Air provides us with oxygen that is essential for living. Nitrogen‚ water vapor‚ and inert gases comprise air along with oxygen. Emission of substances that contaminate air results to pollution. Causes Air pollution is both natural and human-based. Natural air pollution is caused by phenomenon such as volcanic eruption‚ wind erosion‚ decomposition and radioactive

waste products‚ causing unsustainable environments. Cities are sources of air‚ water and soil pollution. Light and noise pollution are now known to adversely affect urban people. The role of urban heat islands and air pollution‚ PM2.5 and ozone‚ on human health is beginning to emerge. Lack of green space may have psychological effects for urban dwellers. We began to explore the nature of the urban environment and pollution on human health and well-being at UEP2010 in Boston in June of 2010. This very

Plastic Pollution Introduction The world population is living‚ working‚ vacationing‚ increasingly conglomerating along the coasts‚ and standing on the front row of the greatest‚ most unprecedented‚ plastic waste tide ever faced. Washed out on our coasts in obvious and clearly visible form‚ the plastic pollution spectacle blatantly unveiling on our beaches is only the prelude of the greater story that unfolded further away in the the world’s oceans‚ yet mostly originating from where we stand: the

like it if someone came into your neighbourhood and started bulldozing the houses down? Many living species have died because of the habitat changes they have to go through. Many oceans and other water bound areas in the world are being polluted by human waste. It’s killing all water creatures and making water unsanitary. If you really think about it‚ we‚ as a community‚ are murderers for polluting animals’ homes and ways of life. We are killing so many creatures each day because of all the waste we
