Causes of Plants Diseases

Bacterial and fungi infections are easy to cure with the use of antibiotics, where as viruses can be hard to cure or vaccinate against, such as the common cold. Bacteria can be found everywhere and anywhere Soil, Water, Plants, Animals, material and even deep in the earth's crust. Bacteria feed themselves by making there food with the use of sunlight and water. We would not be able to live without Bacteria. The human body consists of lots of friendly bacteria which also protect us from dangerous ones by occupying places in the body. Some of the most deadly diseases and devastating epidemics in human history have

In 1845 a crop disease known as ‘blight’ would be introduced to Ireland. It was a disease that would cause potatoes to rot while they grew. It was from guano, which was part of a fertilizer that was imported from South America. The contaminated fertilizer was also distributed to other countries in Europe such as France, Germany, The Netherlands, and England. It was responsible for thousands of deaths in these countries but was soon eliminated, as these countries were not as dependent on the potato as the Irish were.

Harvesting during the 1500s-1600s was an important source for villagers to get their own food. However, in the autumn of 1691, the Salem village experienced extreme weather conditions such as high temperatures and humidity. These conditions failed to make crops and forced the villagers to use rye to make their bread. A well-known Salem farmer named Thomas Putnam supplied much of the colony’s rye flour and donated regularly to the Samuel Parris household, who happened to be Elizabeth Parris’ father (Woolf, 2000). Because of the lack of scientific knowledge of bacteria and diseases, mycotoxin allowed funguses to grow on plants. Mycotoxin is a toxic

The domesticated animals that the Europeans brought carried over diseases such as small pox and measles which ultimately decimated the Native American population along with numerous animals and thus harming the ecosystem. Furthermore, after numerous crops from the New World was introduced to the Old World, there came a rising demand for those crops. This eventually led colonists to mass produce these crops in hopes of selling them for extra money. Excessive farming eventually led to deforestation for farm land along with depletion of the nutrients in American soil (Nun 174). Soil depletion then resulted in poor farming which followed starvation of the colonists and the destruction of American land. This early example shows the dangers of deforestation and poor soil that people still risk today by harming the

Bacteria can exist almost everywhere, some are harmless, and some are harmful. There are thousands of different types of bacteria and they fall

Bacteria are single celled organisms. Some classify them as a separate (fourth) kingdom on the tree of life.

Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body, only 1% of bacteria is actually harmful.

Bacteria - are micro-organisms that consist of only one cell. Bacteria multiply by splitting themselves in two, which is called a binary fission. Because of this they can increase in number rapidly. The majority are harmless, but some can be pathogenic which results in bacterial infection occuring. Bacterial infections can be treated by using antibiotics. Bacteria can evolve a resistance to antibiotic e.g. MRSA. Some diseases caused by bacteria include tuberculosis, pneumonia, salmonella, tetanus and syphilis.

Populations were affected biologically by trade with the debut with alternative crops and the faster spread of disease and

This topic is discussed in Chapter Eleven, it outlines major diseases that killed out many civilizations and how a epidemic survives but still connecting to the idea of agriculture. A epidemic starts when it get exposed and everyone is quickly infected and until those would are left survive and become immune, then the disease dies out. This process helped Europeans infected other civilizations not immune to their germs who they eventually conquer.However, Europeans would have gotten these germs without agriculture. In farming societies, farmers would be surround by their own waste because they didn't have the need to move like hunters and gathers. This gave the opportunity for the disease to have only a short distance to travel until they infected a new person. Disease also traveled with domestic animals which interacted with humans providing another chance to spread the infection. The Europeans had all these aspects, to get germs and infect weaker civilization and to conquer them, right in their own environment. Another important factor of Europe’s superiority is their

organisms are being researched on, such as the Flavr Savr Tomato on 1997, as well as corn crops

In the beginning of the movie, the audience sees that a major blight has affected many crops that they thought were impervious, such as okra. With all of these crops being affected, people are dying because there is not enough food. According to Encyclopedia Britannica, blight attacks the shoots of a plant when they are young. This causes the leaves and sometimes the whole plant to die. To make sure blight does not spread one must entirely destroy the plant, prune them, or

rotists affect everyday life because algae is a food source for many bodies of water and oxygen is made from it. Viruses cause disesase and have a long lasting change on the body. It can also do good using gene therapy and can take advantage of a virus to deliver genetic material. Bacteria affects nature by providing oxygen, food production, health maitenance, medicine, cleanup, amd recycling.

Welcome to the age of an agricultural revolution as everyday biotechnology continues to bring innovation to human’s most basic needs – food. Food is essential to any living organism, providing energy for our production and nutrients for our protection. Without this fundamental element, life cannot exist. Our lack to produce our own energy, like plants, causes us to become dependent on others for survival. Humans existence is attributed only to the million years of evolution our food source underwent to sustain our survival. Changing the primary nature of our food source, whether it is plant or animal, directs mankind in a dangerous future if our food dependency is permanently hampered. Welcome to the age of an agricultural devolution

our crops to be infected with diseases and infestations such as pests and weeds. By
