Soil Erosion And Conservation SOIL EROSION AND CONSERVATION Erosion Erosion is the removal of soil particles by the motion of wind or water. Soil erosion is one of the major concerns of modern agriculture throughout the world. The fallowing contributes to soil erosion: Misuse of land‚ Mismanagement of arable land‚ Indiscriminate felling of trees‚ Overgrazing‚ Poor soil and water management Erosion causes or Results in a: Decline in soil fertility‚ Water supply‚

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

sharp rises in gas prices during 1999 to mid 2008 time period. The sharp rise in gas can mainly be contributed to the increase in the price of oil. The high prices of oil are attributed to the cases of supply and demand. The supply of oil has not increased enough to meet the new demand. Demand for oil has increased over the years in a few countries while the supply stays constant causing the price increase. The price of gasoline is also heightened by the taxes‚ the cost to refine oil into gasoline

What needs to be done to achieve greenhouse gas reduction targets by 2020? Since the beginning of Industrial Revolution‚ concentrations of carbon dioxide‚ methane‚ and nitrous oxide have all risen dramatically because of human activities. Fossil fuel combustion‚ land-use change‚ increasingly intensive agriculture‚ and an expanding global human population are the primary causes for these increases. Other greenhouse gases found in our planet’s atmosphere include water vapor and ozone. Carbon

Agricultural Land Conservation The issues of land distribution and land conservation in agriculture attract more and more attention‚ especially when the expansion of cropland is hitting a limit since much more land is conserved for environmental purposes. Soil erosion is devastating the topsoil of land as chemical fertilizers are used to increase output within a limited amount of land. At the same time‚ livestock production expands at an ever-growing speed‚ worsening the land use situation.

Conservation is the practice of protecting plants or animals‚ and their habitats. These plants and animals may be very close to extinction. North America experienced a big loss of megafauna at the end of the Pleistocene era (about 13 000 years ago). This started a program known as “Pleistocene re-wilding”. Re-wilding involves the reintroduction of extant species into areas where they became extinct in the past. This program aims to restore the evolutionary and ecological potential that North America

Oil Spills Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth. Pollution is the ocean directly affects ocean organisms and indirectly affects human heath and resources. Oil spills is one of the harmful materials that are a major source of pollution in the ocean. “Oil spills stem from accidents involving tankers‚ barges‚ pipelines‚ refineries‚ and storage facilities‚ often while the oil is being transported to its users.” (NOAA 2012) Based on information

or not‚ there are important issues it must consider‚ such as the ability of Canadian provincial and federal climate policies to effectively address rising greenhouse gas emissions. The Final Environmental Impact Statement for the pipeline issued by the U.S. Department of State overlooked key information and context on greenhouse gas emission management in Canada. In fact‚ a close inspection of Canada’s climate record illustrates key weaknesses at the federal level as well as in Alberta. This fact

Fracking for Natural Gas In today’s global fight for the growing demand of energy and promotion of saving energy‚ fracking has become very controversial. The dangers to our society and health are at the forefront in conducting safer practices. To obtain the natural gas‚ fracking or hydraulic fracking must be conducted. Hoffman (2015) explained‚ “Hydrofracking is a controversial oil and gas extraction technique developed in the late 1940s to gain access to fossil energy deposits previously inaccessible

In addition‚ research has been conducted to determine if individuals who are suffering from a medical condition‚ such as cancer‚ may benefit from use of these oils. This research suggests the oils may be of benefit to those who are experiencing stress and other adverse psychological conditions.
