Acid rain is caused by sulfur and nitrogen compounds which can come from natural phenomena such as lightning strikes and volcanic eruptions. Acid rain can also be caused by the presence of human sources such as motor vehicles, electric generator plants, and factories. I chosen this picture because it shows some of the negative effects that society and the environment can impact plants. On the positive side, plants give us the ability to breathe out oxygen and they are important to life on earth.

It shows that when the source of light (which is the sun) transfers into the plant, the plant starts transpiration which is the process of water moving from the roots to small pores on the underside of leaves. The light also targets the chloroplasts which produces the green pigment color of the plant. The plant then starts to make glucose (sugar) which becomes a product of food. ]]> 2018-01-29 16:04:34 UTC https://padlet.com/tboylan/cwhk9jlt5tvz/wish/225698238 tboylan https://padlet.com/tboylan/cwhk9jlt5tvz/wish/232068194 Scientific Name (Taxonomic name): Polystichum acrostichoides
Common name: Christmas fern
Commonly found in eastern North America. From Nova Scotia to west of Minnestota and south to Florida and Eastern Texas. Also found in parts of Europe. It is called Christmas Fern due to its evergreen fronds which are green around December. Ferns are Pteridophytes which have roots, leaves, and stems and are also vascular.

Human exploitation upsets the balance of desert life through draining underground aquifers  and salinisation which poisons the soil. Climate change also presents a problem due to the changes in precipitation and temperature which can cause the deserts to become arid. ]]> 2018-03-06 20:43:26 UTC https://padlet.com/tboylan/cwhk9jlt5tvz/wish/238890669 tboylan https://padlet.com/tboylan/cwhk9jlt5tvz/wish/244144342 The creation of farming and use of animals brought both negative and positive consequences. Farming led people to become permanently settled in one area instead of continuously traveling from one place to another. With the use of this new type of technology, it helped increase populations and created different specialties. On the negative side, it created social class structures which divided the population into 2-3 separate groups (Upper class, middle class, and the working class). Although the benefit of this type of structure is that it allowed trade to be established between different groups. ]]> 2018-03-20 16:54:19 UTC https://padlet.com/tboylan/cwhk9jlt5tvz/wish/244144342 tboylan https://padlet.com/tboylan/cwhk9jlt5tvz/wish/246675567 I chose the tractor because it became both a large innovation and impact during the Agricultural Revolution. The tractor was invented by John Froelich in 1892 which started as a gasoline powered engine and later Benjamin Holt invented the crawler-type tread tractor around the same time as Froelich's invention. The tractor had the ability to plant, plow, and tilling the fields in a fast and effective way. The tractor is a very popular vehicle and tool for farmers in today's world and is manufactured by some of the best known companies such as John Deere. ]]> 2018-03-27 19:48:25 UTC https://padlet.com/tboylan/cwhk9jlt5tvz/wish/246675567 tboylan https://padlet.com/tboylan/cwhk9jlt5tvz/wish/251794535 I believe caffeine is the most influential chemical that is used in the world coming from plants. Caffeine comes from Xanthine which is found in bark of coffee and citrus trees. The chemical/drug is commonly found in drinks such as coffee, Coca-Cola products and tea leaves.]]> 2018-04-14 14:06:36 UTC https://padlet.com/tboylan/cwhk9jlt5tvz/wish/251794535 tboylan https://padlet.com/tboylan/cwhk9jlt5tvz/wish/254889659 I chose this picture because it shows of what I envisioned if present day agricultural, economic, social, and political practices go unchecked. If unchecked, the political and economic systems would collapse and society would be more controlled by dictating or totalitarian governments. Environmentally there would be no life left in existence and everything is subject to disaster.]]> 2018-04-24 15:35:27 UTC https://padlet.com/tboylan/cwhk9jlt5tvz/wish/254889659
