Environmental changes are occurring, such as deforestation. Some lemurs rely on certain diets, like the bamboo lemur which eats only bamboo. Deforestation occurs when loggers clear-cut the trees and natural habitat of the lemurs. It is a longer process to evolve to the changes than it is to clear the habitat in which the lemurs live and eat. Using the bamboo lemur as an example, if people continue to cut down the bamboo, the lemurs will not have food and they could become extinct very quickly.
And so he removed everyone from the cities and put them on the farm. Those counter-revolutionaries that resisted were killed, since they would not enjoy living in the socialist paradise he was creating on the farms. It is his desire to form this rural socialist ideal that led to the Cambodian genocide. Pol Pot’s motives were the following: * Urban and Western life: The cities were evacuated and millions were marched into the countryside in a fanatical attempt to create a pure peasant society. * Capitalism: To make the country self-sufficient, it was turned into a giant labor camp – radical form of agrarian communism.
Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Wind and water erosion then damages the soil left unprotected. To help prevent overgrazing the NRCS (U.S. Natural Resources Conservation Services) has a program (the Conservation Stewardship Program) that provides information and support to enable ranchers who own their lands to burn unwanted woody plants, reseed the land with perennial grass varieties that hold water and manage cattle so that herds are moved to a new location before overgrazing occurs. These steps should help supply enough area and grass to prevent an insufficient supply for grazing. This problem, if left untreated, could also pose a serious threat to the food chain.
Carson provides rational examples to show the harm that pollution is causing to the earth and pests. Carson states, “Can any one believe it is possible to lay down such a barrage of poisons on this earth without making it unfit for all life?” (605). Rachel Carson is trying to prove that spraying chemicals is not relevant because it causes harm to nature and anything else that comes in contact with the chemicals itself. Carson uses this scientific observation to prove that the cycle is continuous; all it is doing is causing more harm. As is it perceived, Carson feels passionately toward the environment and wants her audience to feel the same way.
What impacts might result if everyone in the world enjoyed the same lifestyle? For example, what might the impacts be on: • Earth’s climate? The earth would be tremendously ruined because everyone would be using fossil gas that we burn for our usage, and the fertilizer that farmers use on their farms to grow crops • The health of ecosystems and biodiversity? A lot of animals will go instinct so we will have food storage. We will also have air and water pollution that will start diseases for us humans.
Bees provide pollination. If bees weren’t pollinating our food, all we’d eat is stuff like “grains and grasses.” By pollinating flowers, it’s helping flowers reproduce. If we didn’t have bees, our plants would die, which would lower the oxygen levels on earth. Bees are dying every minute and if we don’t start saving the bees then we will barely have anything to eat. You can help the bees by planting things that bees like.
The Dutch Elm Disease, is known to spread across trees, mainly the Elm Tree. The Elm Disease would take over the tree and spread by the fungus that was upon it. On these trees, little bark beetles would carry this disease. When the government found out about this, they decided that their best option would be to kill the beetles so they would not spread this disease. They started to spray the trees with pesticides.
Eventually there was an evolutionary spurt called “orthogenic” that led to humans being the alpha of hunting. (Page 37) This was through the use of language and creating weapons. Mankind did not fit in the puzzle anymore. Human kind was considered a disease to other life forms by taking away their food and killing a multitude of them off. Because the parasites depended on these life forms to survive, it needed to hurt what was killing their hosts.
Growers that are not growing organic foods use pesticides and are the only toxic substances released intentionally into our environment to kill living things. This includes herbicides that kill weeds around the plant so the weeds can’t take the nutrients from fruits and vegetables. Insecticides to kill or deter insects that eat the fruit
Insects eat plants, birds eat insects, bacteria and fungi in the soil decompose birds and other organisms when they die, and plants obtain vital nutrients from the soil. Food webs for ecological communities may be extremely complex. 4.How could human behaviors and rising human populations impact these cycles? Humans can eliminate species and life by pollution or killing. Humans need to monitor their actions by moving life to a new location
