Energy is needed in order for living things to grow. Our main source of energy on Earth comes from the sun. Plants use the light from the sun for photosynthesis, and plants source of food comes from photosynthesis. T need the sun to produce their own food they do eat plants, and all plants go through photosynthesis. Planets that the are far from the sun, such as Pluto, can not use the sun? S light to produce food. Photosynthesis could never happen on Pluto. Therefore, there will never be any life on Pluto. In addition, living things also require water.
Dangerous animals, vast oceans, and violent weather have presented risks to humans. However, the new frontier of outer space, with its vacuum, meteors, and lack of water, presents unique challenges to people who desire to explore. Perfect Planet Essay, research Paper, what is required for a planet to be able to support life? This is a question that people have been trying to answer for many years.

As one can see, the challenges of space travel are rather different from terrestrial dangers. Here is another example of a concluding paragraph: As mentioned above, the earth's natural environment has often presented dangers to explorers.
Many of these objects travel at very high speeds. Under the earth's blanket of air, people are usually protected from metor impacts. However, in space, people and spaceships are vulnerable to collisions with meteors. It is true that the chance of metor impacts is relatively small, but if even a small micrometeor happens to collide with a spacecraft, it could cause serious damage. A third special challenge involved with the environment of space involves the fact that it is very difficult to find life-sustaining water off the earth.
For example, the planet Mercury, which is closest to the sun, is too hot to have water, so space travelers must take water from Earth if they want to visit Mercury. A similar situation exists on the planet Venus, second from the sun. This planet is likewise too hot for water to exist.

After too many minutes without oxygen, a person would tree lose consciousness and eventually die. Also, in a vacuum a person's blood will gradually begin to boil. Finally, without an atmosphere, the rays of the sun can cause radiation poisoning. Another difficulty that is unique to outer space is the presence of meteors and micrometeors. These are pieces of rock and metal that are left over from the formation of the solar system.
This main thesis functions like the topic sentence of the basic paragraph, which we have studied in Lessons 1 and 2. It is illinois the most important sentence of the essay.

The next two sentences give some supporting examples of this intital sentence. However, the third sentence of the paragraph gives an example that contrasts in some way with the previous two sentences.
