A comet is a lump of rock and ice. Spacecraft have flown by comets. A comet only has a tail when it is near the sun. Most comets come from the Kuiper belt. A comet has actually been witnessed hitting a planet. Most comets have short orbital periods.

A comet is a tiny, frozen entity in the Solar System that heats up and starts to emit gases as it approaches the Sun. This process is known as outgassing. This results in an apparent atmosphere or coma, and occasionally a tail as well. These occurrences are caused by how the solar wind and solar radiation interact with the comet's nucleus.

The size of comet nuclei varies between a few hundred meters and tens of kilometers, and they are made up of loose clumps of ice, dust, and tiny rocky particles. A comet's orbit is typically very eccentric and elliptical, and its orbital period can range from a few years to possibly millions of years.

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.
