Human Overuse of Resources Calls for Second Earth According to a UK study‚ growth of the population and an increasing consumption of resources could leave humans in need of a second planet as early as 2030. Human demands on natural resources have doubled in less than 50 years‚ according to the Living Planet Report. The rate at which resources are being utilized with the population as is – or growing – will exceed the capacity of the planet in about 30 years. The report also said tropical

Human Activities and the Loss of Natural Resources Natural resources including soil‚ water‚ forest‚ mineral and biodiversity have been repeatedly destroyed around the world by humans. “Since 1970‚ over 600‚000 square kilometers (232‚000 square miles) of Amazon rainforest have been destroyed” (Butler‚ 2011). The FAO (Food and Agriculture Organization) estimated that “soil erosion carries away a volume of soil equivalent to one metre deep over 200‚000 hectares every year in the Philippines.” In

Deforestation The cutting down of forest or deforestation can affect us and have serious effects on our environment as well. A few effects of deforestation are soil erosion‚ disruption of the water cycle‚ and possible even global warming When forest areas are cleared‚ it results in exposing the soil to the sun. Which would make the soil very dry and eventually‚ infertile‚ due to nitrogen being lost. In addition‚ when there is rainfall‚ it washes away the nutrients‚ which flow with the rainwater

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. Livestock production

(LAI) Leaf area of five randomly selected plants‚ was measured with the help of leaf area meter (Model LI-3100‚ USA) at 20‚ 40 and 60 DAS by destructive sampling from all leaves of the five sample plants (Sticker et al.‚ 1961). Plants were cut at the soil surface‚ leaves were separated from the plants‚ covered with blotting paper to keep the leaf intact and retain its original shape and were brought to the laboratory. Leaf area was measured immediately after bringing them in the laboratory. Leaf area

In the context of a contaminated soil‚ the health of human beings‚ animals or plants‚ ground or surface water and buildings which are normally polluted with substances contained by contaminated soil are termed receptors with respect to the definition of contaminated lands. The contaminants are referred as the ‘’Source’’ while the soil is termed as the pathway. Countries such as US and UK have large industrial productions which have

Leaves as Mulch for Solanum lycopersicum (Tomato) ABSTRACT Mulching in agricultural provides a safe yet equally profitable method of enriching and fertilizing the soil planted with crops. Most often-used mulches are of organic composition‚ such as dry leaves and barks. These organic mulches pose no or little damage to the soil and crops. This study deals with the effectiveness of dried papaya leaves as organic mulch for tomato. This study further aims to evaluate the results and compare it
