INTRODUCTION Love Canal is a canal existed in Niagara Falls, New York. Love Canal is named after William T. Love. Love Canal Tragedy is concerned with the heavy amount of toxic waste disposal in canal and related health problems originated from the event. LOVE DREAM Love Canal was originally a dream community. A dream seen by William T. Love. He wanted to dig a short canal between upper and lower Niagara Rivers. The purpose for which the canal was made was to generate the electricity that could be supplied to industries and homes to make the city a model city.  The Love dream was not able to endure the changes such as change in economy and Nicola Tesla discovery how to transmit economically the power to long distances through alternating current. THE LOVE CANAL TRAGEDY In 1910 Love dream was devastated by a trench dug at the site where Love Canal has to be started. By 1920 nightmare seeds were planted at the site. Gradually the canal was converting int...

What is Green Revolution? There were many revolutions occurred throughout the history such as American Revolution and Industrial Revolution. The Green Revolution occurred in in mid and late 20th century and in this period global agricultural yield was increased dramatically.  Why Productivity increased? The productivity in agriculture field was due to new technological advances in agriculture. New chemical fertilizers, herbicides and pesticides were made. The chemical fertilizers were used to increase the nutrient content in crops and to provide better yield of crops. Herbicides and pesticides were used to kill the pests, herbs and insects. These also controlled the diseases. High yield crops were produces and used in the field. These are the crops that are designed to produce more yield. Multiple Cropping was also adopted in that period. Multiple cropping is the method in which two or more than two crops are grown in the field throughout thee year to gain more yield...

Introduction The dust bowl in America is a catastrophe event occurred in early 1930's. It caused the Midwestern and western farmlands conversion to wastelands. The major reason behind the dust bowl was series of dry years faced in America with vast agricultural practices in unsuitable areas.  Impacts   Poor tillage practices causes the dust storms and droughts that that devastated the farm lands and ranches in Great Plains. This disaster left nothing behind no humans no nutrients and no plants cover. The humans moved towards other areas that have more fertile farmlands Events that led to Dust Bowl The European settlers arrived in the Great Plains.  They build the farms and ranches. Cattle ranching provide the benefit for users but ranching caused the overgrazing and degradation of soil. Farmers plow the natural grass and replace them with their own crop. Row crops caused the dam...

The freshwater available on the planet earth is enough that it can meet the demands of humans. But the distribution of water is not proper. For Example the Citizens of Bahrain, a tiny island in Persian Golf, have no freshwater availability and they desalinize the water for use. The per capita utilization of water vary from continent to continent and from one country to other country. Some countries receive the more water but their utilization is not proper while some have low water availability but they use it in effective way. South America and Asia together receives almost half the share of water resources of world. South America receives more water compared to Asia but South America has not the much potential to support the people with water. That's why the water falls in Amazon River that has poor soil and it does not support the agriculture. Asia receives less water than South America but water supply support the humans because the land where precipitation ...

HYDROLOGIC CYCLE "The continuous circulation of water through abiotic environment from ocean to atmosphere than atmosphere to land and than back to the oceans is called hydrologic cycle. It is complex cycle." Hydrologic cycle maintains a balance of water among oceans, land and atmosphere.  Sea Water Sea Water accounts a large portion of water on earth surface. Almost 97 % of water of earth surface is found in the oceans. The oceans consist of dissolved salts. Sea water is too saline that if this saline water is given to plants, the plants will die. Humans can also not utilize this water for drinking purpose.  Fresh Water The percentage of freshwater on the earth surface is very low. Only 2.5 % fresh water is there on earth but from this 2.5 %,  1.97 % water is in frozen form in polar ice or glaciers that is not in use for humans; 0.5 % water is available in ground water; Only 0.03 % water is available in lakes, rivers, streams, soil moisture and atmosphere. It can been se...

POPULATION GROWTH Population growth is simply the increase in number of individuals. In population growth many factors are correlated such as population size, consumption of resources, technology used to obtain energy and environmental impact associated. POPULATION SIZE AND RESOURCES CONSUMPTION Population size is the number of individuals. Resource consumption is defined as the use of resources (materials and energy) by humans. People in the developed countries use the resources in excess. The average US child greatly deplete the resources and cause environmental impact than dozen or more children in other developing countries do. According to Worldwatch Institute in Washington, Americans consume 10 billion tons of resources each year. This large consumption of resources by US and other developed countries lead to major environmental impact and over consumption of resources. PEOPLE OVERPOPULATION AND CONSUMPTION OVERPOPULATION People overpopulation is caused due to large...
