First Slide
A: Plants and the Atmosphere: Facts and Relationship
B: This is a PowerPoint slideshow consisting of slides of information, and a few flash animations to illustrate what is meant.
A: The slideshow will state facts about plants and trees, and showing how they affect the atmosphere.
Next Slide
A: As you know, plants don’t really move unless while growing.
B: This is because plants have no reason to move a lot. So they have roots to hold them to the soil.
A: These roots help plants get all the minerals and water they need from the soil and allows them make their own food. Roots will generally grow toward the direction of water
B: The rest of the plant usually grows upwards, unless there is little sunlight, where it would grow toward the area with the most light.
Next Slide
A: Photosynthesis is a process that occurs in plants. It is the process that enables them to make food.
B: That’s why we can’t make food. We photosynthesis doesn’t occur in us.
Next Slide
A: As we mentioned earlier, photosynthesis occurs in plants due to chlorophyll. Chlorophyll is a green pigment that absorbs and traps sunlight.
B: Most leaves are green because of these pigments. Other leaves have other pigments covering them.
Next Slide
A: This is a summary of everything that’s been mentioned earlier.
B: Also note, if you didn’t already know, that mushrooms and toadstools are fungi.
Next Slide
A: Trees are basically large plants, so the almost everything said about plants can apply to trees, and vice versa.
B: Trees and other plants do, in fact, cause harm to our atmosphere. However they generally do more good then harm to our atmosphere. That is why we are still alive in this world.
Next Slide
A: Trees are living things too. They need to respire just like us. This means they give off carbon dioxide just like us.
B: Also, when living things decompose, they give out carbon dioxide, as well as a few other gases they could be harmful to our atmosphere.
Next Slide
A: Carbon dioxide is not the only greenhouse gas in the world. There are several other kinds, like methane and nitrous oxide.
B: All of these gases have different levels of impact on the atmosphere, meaning some are more dangerous than others. They are determined by their global warming potential, or GWP.
Next Slide
A: Apart from saving trees, there are many things that we can do to reduce global warming. For example, taking public transport instead of driving cars can reduce gas emissions.
B: Our diet also indirectly affects global warming. Research shows that breeding livestock contributes the rate of climate change. Running slaughterhouses, meat-processing plants and even pumping water all contribute to the gas emissions.
A: Even the livestock themselves give off carbon dioxide!
B: What’s more, populations worldwide are expected to increase, meaning more livestock need to be bred to satisfy our hungers. In order to do that, deforestation to expand pastures are necessary.
