Natali5045456 [20]

Answer:

Explanation: Dear Sirs:

    I am writing today to urge you as strongly as possible to stop your deforestation program in the rain forest there in South America. Although for you the objective is financial gain, for the rest of us it is the destruction of land, habitats, people and eventually, the Earth.

   Deforestation is a process where large areas of forests are cut down to be used for farming, grazing land for cattle, and housing. This is especially true inn the South American rain forest where you are working. These are not necessarily bad things, but the effects of deforestation are devastating. Deforestation is achieved by cutting or burning of trees from a widespread area. Why does this matter?

    When deforestation occurs in an area, animals and plants are forced to move from their natural habitat. For many of these species they are unable to survive in new forced into areas. When the trees are cut down, the stumps are then burned to release nutrients into the soil to enrich it for farming. This is called, "slash and burn." However because of the heavy rains,and no tree roots to hold the soil, the nutrients are washed away and soon the farmers must move to a new area, and start the process all over.

      Further, deforestation can cause climate change. Obviously without the trees available to capture the Greenhouse gases, like carbon dioxide, stopping the gases from accumulating in the atmosphere and warming our planet. Climate change is a real issue that must be addressed if our planet is to survive.

       With all of these problems, what are the benefits? Who wins? Who loses? The benefits are to your company who now have a large tract of freshly cleared land that can be used for farming, cattle grazing, logging or housing. As always the almighty dollar comes to the forefront. The losers are the plants, animals and indigenous people who live in that area. Forced to relocate, many of all the groups will not survive. With the increased use of deforestation, the benefits are far outweighed by the cost- our planet Earth.

        What are the alternatives to land desertification?  There are better and more innovative ways to grow food and clear land, one of which is sustainable land management. It is a process to prevent, minimize, or reverse land degradation. There are organizations worldwide that will help you to find better solutions than deforestation to reduce carbon pollution, to safeguard arable land, repair degradable land and to manage water supplies more effectively.

          In closing, I strongly urge you to reconsider what you are doing in an area that can ill afford any more destruction. Why does it matter? Perhaps it doesn't to us in 2020, but to our children's children it will matter greatly if climate change destroys the Earth.

The igneous rock gabbro most likely formed
weeeeeb [17]

Slowly, deep underground

The igneous rock gabbro is coarse grained and non-vesicular. Both characteristics show that it is an intrusive igneous rock. Intrusive igneous rocks are formed below Earth's surface and slowly (because they're underground). When rocks are intrusive, they are are non-vesicular (no air pockets) because the air has had the time to escape because of the slow cooling time period. Intrusive rocks are also coarse because crystals had the time to form in the rock during that longer cooling time.

Ps. extrusive igneous rocks form rapidly at Earth's surface and basically have tge opposite characteristics for the opposite reasons (ex: vesicular cause air had little time to escape)
