How Do Humans Affect Plant Domestication?

However, due to more people searching for plots there is greater pressure on the amount of available land. The logging industry is responsible for a relatively small level of deforestation, accounting for 3% in Brazil. Consequently, all these activity contribute together to the rapid loss of what is left of the rainforest and a large proportion of the world’s biodiversity. All of the resources that the rainforest provides could be lost in the next 40 years.

Finally, the Brazilian government and the rest of the world must come to realize that the increasing destruction of the rain forest threatens the delicate balance between humans, plants, and animals. The Kayapo have successfully maintained this balance for thousands of years. We have an obligation to ensure they are able to continue to maintain this balance.

The domestication of plants and animals lead to great change in the development and structuring of communities, as the hunter-gatherer lifestyle was slowly replaced by permanent settlements of farmers and villages. We can see that the communities varied greatly dependent on their local ecology, the resources available, and the time period within which their community was based. The road to agricultural way of life in the MIddle East is characterized by Four distinct stages. It was during the Kebaran period, and Geometric Kebaran in which hunter-gatherers began to utilize the plant and animal resources of the region. Architecture became a prominent feature of the Natufian period, as communities began to transition to village life from

In Middle and South America, it is evident that human interactions affect the physical features. The human interaction that affects Middle and South America is deforestation. In 1970’s a period of deforestation began in Brazil with the construction of the Trans-Amazon Highway; the road allowed migrant farmers to grow crops (Pulsipher & Pulsipher 2012). Deforestation continued throughout Middle and South America. The use lodging of hardwoods, extracting minerals, oil, gas, stones and clearing off land for raising cattle, and growing crops has impacted most of the land in Middle and South America (Pulsipher & Pulsipher 2012). The human interaction of deforestation has led to many environmental issues, changes in physical features. There are loss

Brazil was noted as having a fast-growing agricultural sector and the concern regarding deforestation has grown. In turn, efforts have been made to protect land by granted protection status to over 500,000 sq. km of the Amazon rainforest. Efforts such as these have been successful in limiting the destruction of deforestation.

Existing near the equator along countries such as Brazil and Costa Rica, this zone has a combination of warm temperatures, high humidities, and abundant precipitations. Factors like these define what the tropical zone is. For example, due to the high temperatures and frequent rainfalls, the soil is considered poor. This is so, because the temperature and the rainfall causes a quick decomposition instead of building up of organic materials in the soil. Therefore, once the tropical zone is altered by human activities, it is very hard to recover with the nutrient poor soil. In addition, it is expected that in the tropical zone there would be large trees. These large trees creates a closed canopy in which light just barely reaches the forest floor. Going along the topic of sunlight, it is a crucial abiotic factor in this zone. Consequently, there is competition among trees to obtain the limited amount of sunlight through the various vertical stratification of tree levels. Some key characteristics of trees in relation to their habitat is their ginormous height. In this zone, rainfall determines the vegetation. Thus, with the abundant rainfall, trees can reach up to fifty to sixty meters in height. Another key characteristic is their diversity. It has been reported that in a 2.5 acre land, there is approximately three hundred different species of trees. The main type of

Plant domestication leads to a major difference in society because it permits the members of that society to reproduce, form permanent societies, and create a bureaucratic society ( also gives the ability to tax). For example, “ by collecting huge quantities of wild cereals in a short time when the seeds were ripe,and storing them for use as food through the rest of the year, some hunting-gathering people of the Fertile Crescent had already settled down in permanent villages even before they began to cultivate plants.)

Tropical rainforests have long been home to indigenous peoples who have shaped civilizations and cultures based on the environment in which they live. Great civilizations like the Mayas, Incas, and Aztecs developed complex societies and made great contributions to science. Living from nature and lacking the technology to dominate their environment, native peoples have learned to watch their surroundings and understand the intricacies of the rainforest. Over generations these people have learned the importance of living within their environment and have come to rely on the countless renewable benefits that forests can provide.

The rain forest is an important and very reliable part of the world. Recently there has been a lot of controversy over if they should develop it, or let it grow. This paper will discuss those pros and cons and show the uses of the rain forest. According to “GREEN GARAGE” The pros of deforestation are it creates space for growth, it produces more useable material, it allows for civilization and industrialization, it creates more job openings, it allows for the opportunity for graze animals, it creates the chance for more food production, and it allows people to generate more revenue. These are just the pros of deforestation of the rainforest, there are still cons and bad consequences of deforestation.

Amongst the world, there are many controversial issues related to globalization and within the environment that many scholars delegate prolonged hours into research. With globalization rapidly intensifying, one specific aspect is the incredible amount of land use changes occurring globally, which have in turn embellished altering effects within societies particularly Brazil. Globalization and more abstractly speaking land use changes have often at times caused many cases of reformation amongst communities, having altered the livelihoods of many. One of the greatest and most widely debated topics over the environment within the past century is deforestation within the Amazonian region in Brazil, and continues to play a key role in many indigenous

Ever since 1900 which the start of the industrial revolution, the forests have been reduced by one-half and to make the destruction worse of rainforest rapidly is due to World War II where the forests had reduced to 59 percent. Today, approximately 10 million sq km remains, and tropical rainforest still covers somewhat more than 6 percent of the earth’s land, in four major areas of the Americas, Africa, Indo-Malayan, and Australian- Pacific. There are about 50% of the worlds tropical rainforest cover are in American block or Neotropics. Indeed, there are five countries with the largest rainforest cover which are Colombia, Indonesia, Peru, Democratic Republic of Congo and Brazil. However, the majority of the forest covered within Brazil which

Land is greatly affected by the meat industry. The percentage of U.S. agricultural land used to produce meat is 56%. The strains on land include topsoil erosion and depletion of forested areas. The percentage of U.S topsoil loss directly associated with livestock raising is 85%. In Mexico 37 million acres of forest have been destroyed since 1987 to provide additional grazing land for cattle. The cattle industry is a driving force behind the destruction of the tropical rainforests. Until 1994, in the Amazon the total deforested area was of 450, 000 square Km. The current rate of species extinction due to destruction of tropical rainforest amounts to one thousand per year. Various species of plants live in the tropical rainforest, which can be used for their medicinal properties. These plants need yet to be discovered. We can not afford to risk their extinction.

The rate of deforestation is increasing and the tropical forests are falling at approximately 140,000 acres per day (Miller & Tangley 1991: xvi). The forests are crucial to the environment. They are important in minimizing erosion, providing a stable habitat for many animals, and helping to keep the environment clean. Deforestation has devastating effects, not only on the biological dependents within the depleted forests, but also on the surrounding human-populated communities.

Today forest loss due to conversion into to other land use has reached a dangerous level. Recent study conducted by the researchers from the University of Maryland, the State University of New York, Google, the U.S. Geological Survey, Woods Hole Research Center, and South Dakota State University shows that during 2000-2012, the world forest was lost with approximately 2.3 million square kilometers per year. Particularly in Indonesia, they said that deforestation rate increases from 10,000 square kilometers in 2000-2003 to 20,000 square kilometers in 2011-2012. As stated by XXXXX ( ) that forest essentially has role in regulating the water,,,,,,,,,,,,,,,,,,,,,,. In other word, Forest loss can lead to variety of devastating impacts such as floods, droughts, and landslides. These trends tend to be more awful in the future unless appropriate actions. This essay will describe the implication, identify the main causes, and suggest solutions.

Rain forests have been shown to provide people with many benefits. It contains plants that are used for timber, foods, and medicines. They help regulate the Earth’s climate and allows clean air in the environment. There are many living things in a rain forest. Plants are one of the most abundant things found. About forty-five percent of the world’s plant species live and grow there. There are also over two hundred fifty species of trees. Animals are also an important part of a rain forest. Some of the main animals include fish, amphibians, reptiles, birds, and insects. There are also millions of people who live in rain forests.
