1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points)

2. a) As the amount of precipitation increased, the amount of eroded loose soil increased significantly as well. The line of best fit also shows that in the future there will be more eroded loose soil if precipitation numbers increase like they have.

The causes of deforestation vary in number a few have made a big impact on the problem. The USA's population has increased by over a hundred million people since 1970, more than half of the whole population at the time. As seen many factors come along with a growth in population things such as, a need for more space, and a need for more wood for conventional uses, all contribute to the huge increase of deforestation. With nearly one-quarter of America’s tree canopy existing in our backyards, city streets and parks, our population has a huge responsibility,according to, “United states, plant a billion trees”. The next big contributor to the problem of deforestation in the U.S. is land for livestock. In the U.S. one of the biggest causes of deforestation is land for livestock. The single biggest direct cause of tropical deforestation, is conservation to cropland and pastures, mostly for subsistence, which is growing crops or raising livestock to

Between 1990 and 2005 the 5 countries that cleared the most tropical forest by area are:

Deforestation is the destruction of a wide area of forest land into a cleared land that is used for a variety of reasons. The impact on the environment from cutting down, burning and damaging forests is very detrimental and there are severe consequences for the environment and future generations because of deforestation. According to the United Nations' Food and Agriculture Organization approximately 7.3 million hectares of forests are being destroyed per year in the world (Bradford, 2015). In this essay, I will explore the impact that deforestation on the environment and I will also look at the actions that are being taken to prevent deforestation. There are various reasons why deforestation is occurring despite its negative effects on the environment. Deforestation can cause very serious environmental problems such as climate change, flooding, loss of habitats as well as others.

Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious

Deforestation is known to be the destruction of forests and woodlands. It is also one of the causes that lead up to drought. Deforestation increases the risk of drought by taking all of the groundwater from soil, which they heavily depend on to stay healthy (Deforestation, 2014).

The pace of this deforestation is unprecedented in recent times. According

With new technology such as satellites systems, low altitude photography and side looking radar scientists now figure that the world is losing about twenty million hectares of tropical forests annually. It has been suggested that the high deforestation rates are caused partially by the fact that the new surveys are more accurate and thus reveal old deforestation rates that were miscalculated with previous methods (Westoby, 202).

There are many causes/factors to deforestation, which are largely associated with direct human influence. The first proximate cause to deforestation is infrastructure expansion (Geist & Lambin, 2002, p. 144). This refers to transportation (roads), private and public markets, rural and urban settlements, and private and public services (water lines, oil exploitation, etc…) (Geist & Lambin, 2002, p. 144). The next cause is agricultural expansion, which includes, large or small-scale cultivations, shifting cultivations (slash and burn), and, of course, cattle ranching. Wood extractions for industrial and domestic purposes are other proximate causes to this issue.

Deforestation for agricultural purposes and the expansion of human habitats is happening around the world. This

Global warming has become a serious problem for us, and the Earth itself. Global warming is when Earth’s temperature increases, due mainly to human activity and the greenhouse effect. This is affecting our atmosphere, causing an increase in temperature. This is mostly humans’ fault since we are the ones that contribute the most to global warming. Due to overpopulation, the demand for many of the things we use everyday have increased dramatically. Factories and the burning of fossil fuels for example, contribute a great part to global warming. Deforestation however, is a greater problem than the two previously mentioned. There are many trees being cut down for different reasons, and this has become a major driver of global warming, responsible for up to 20 percent of global greenhouse gas emissions–more than all the cars, trucks, planes, boats and trains in the world combined” (Solutions to Deforestation).

Tropical rainforests cover approximately thirty percent of the earth’s land area, around 2.5 million square miles, the size of the lower 48 states, despite the fact 80,000 acres (32,000) hectares are destroyed per day for economic reasons. Tropical rainforests are biodiversity hotspots. Rainforests are carbon sinks absorbing about half the carbon dioxide humans release into the atmosphere. Continued deforestation will affect the entire world with the ecological ramifications of species extinction, loss of carbon sinks, and loss of renewable resources. Deforestation reduces the availability of renewable resources like medicinal plants, timber, nuts and fruit, and indigenous game. Over time, loss of
