1.1 Introduction to Landslide A landslide is a geological phenomenon, which includes a wide range of ground movements, such as deep or shallow failure slopes and rock falls. See figure 1.1. 1.1.1 Factors influence Landslides Landslides occur when the stability of the slope turns from the stable state to unstable state. Most of the Landslides usually cause depend on two main factors: (i) Natural Factors and (ii) Anthropogenic Factors. (USSG, 2004) (i) Natural Factors (a) Geological…

In current news, global warming, which is defined as “the gradual heating of Earth 's surface, oceans and atmosphere” (Bradford, 2014), has been a significant topic of interest. Among politicians, environmentalists, and concerned citizens, the impacts of climate change have been heatedly debated. While a portion of America believe that climate change is not a serious threat, is not caused by mankind, or perhaps is not even real, another portion believe it is the most terrifying and imminent…

Although the rainforest is known for poor quality soil in the soil industry, the agricultural industry clears the forest for cropland. (Stief) Mining also strikes the tropical rainforest as a threat. Mining in the tropical rainforest is used to excavate very unique mineral assets, like copper, tin, nickel, bauxite, manganese, iron ore, and gold. This mining is taking place in the Amazon, and as a result of it, governments are providing tax incentives for large-scale projects, in order to boost…

In the words of President Barack Obama “…Science, accumulated and reviewed over decades, tells us that our planet is changing in ways that will have profound impacts on all of humankind…those who are already feeling the effects of climate change don’t have time to deny it—they’re busy dealing with it.” Global warming is already beginning to alter life on Earth with rising sea levels, poor air quality and increasingly severe climate changes. To help slow global warming, the government should set…

forming the edge with differences in vegetation height and cover being the primary structural variables that influence edge response strength.” (Craig et al. 2015) When open pit mining takes place it causes a vast difference between the habitats in a relatively short distance,…
