Without human activity and if the climate of the British Isles were to stay the same the whole place would reach climatic climax of oak/ash/beech deciduous woodland. It depends on the soil type as to which climatic climax species is present. However, many factors such as human intervention and climate can cause changes to plant succession in an ecosystem. Succession is the evolution of a plant community from its pioneer species to its climax community. All the living and non-living things living within a certain area is known as an ecosystem.
The Industrial Revolution began in England in the middle of the 1700s. It marked a time period of major change in the nature of production where machines replaced hand tools and steam and other sources of energy replaced human or animal power. Production became efficient and mass production of goods marked the beginning of a new economy (History Guide, Lecture 17). In Canada the new economy involved the growth of industry and establishment of many factories required to manufacture the increased demand for goods. Many iron and steel factories were created to manufacture agricultural equipment as well as machine shops, textile and shoe factories (Francis et al., 133).
Mountains are areas of lands with steep sides that rise sharply from surrounding land. They are many examples of mountains like the Himalaya Mountains, which are located in India and the Alps Mountains, located in Europe. These mountains have both helped and hindered these civilizations. Mountains helped civilizations because they cut steep steps on the sides of the mountains and grew crops there. They called this terrace farming.
In early human history, environmental change was usually the biggest reason people migrate from one place to another (Wood, 1994). Flooding, lack of land, and cold climates would push people out of their native lands. Migration also occurred for economic reasons including overpopulation and flooding of plains used for farming (Wood, 1994). Political reasons for migrating usually involve escaping war or invasion from other empires or tribes (Wood, 1994). .
Controversial Essay : “What impact do human activities have on rainforests and is it possible that this threat would someday affect us ? “ Introduction As globalization developed in the current years, the demands of resources have been growing widely. One of the most valuable resources are unarguably forests’ such as lumbers and timbers. These resources are very useful as they are materials for construction, fuel, or even pulp and paper. Of all those forests, rainforests are the most targeted ones.
The weather played large role with the increasing temperatures at the end of the last great ice age. The end of the last great ice impacted on the vegetation & animals, this may have force a change from Mesolithic hunter-gathers to Neolithic agriculture. The large amount of vegetation, cereals and animals sheep's & goats, which were later on cattle's and than domesticated animals, as well as the relaxed life style. Technology had evolved over the years due to the change of lifestyle. heavier tools became more important than the light stone blades of the
B. Rural Environments 1. Almost all the land in Europe had been transformed by human activity before the Industrial Revolution, but deforestation was an ongoing problem. Americans transformed their environment even faster than Europeans did, clearing land, using it until the soil was depleted, and then moving
Temperate Forest Summary Bio 101 September 15, 2014 Temperate Forest Summary There are various types of forest set within planet earth, which are complex ecosystems with dynamic characteristics that are set by specific features: physiological variations, the form of plant and animal life and the process that initiate these dynamics. Temperate forest biomes are ecosystems that consist of an abundant amount of plant and animal species. The following passage will provide a brief summary of the various characteristics of the forest, geographical areas of forest locations, population growth, and how the forest regulates its population. Temperate forests are several regions in the Eastern part of North America, Western Europe, China, Korea, Japan, Australia, and a small part of South America. A temperate forest experience all four season although climate is moderate in comparison to tundra and taiga forests.
3) a) Explain how physical factors influence the distribution of biodiversity shown. (10) There are several factors influencing biodiversity including; isolation, age, altitudinal range, and the conditions for photosynthesis. The Himalayas have over 4000 plant species per 10000 km2 due to the large altitudinal range which means more climatic zones are involved creating more diverse habitats such as rock faces, steep hills. This means there are more species able to live in these different climatic zones as they require different conditions. The most bio diverse areas are between the tropic of cancer and the tropic of Capricorn.
The deglaciation of ice sheets and glaciers, which happens when we enter a interglacial warming period, are important because they have an immense impact on the land structure and vegetation throughout our continent, as well as the rest of the world. The deglaciation of the Wisconsin Glacier caused the formation of the Great Lakes as well as Niagara Falls in New York. This melting of ice sheets also causes sea levels to rise which covers landforms. The water submerges bridges and passageways between continents that were used by animals which migrated from continent to continent. This prevents certain species of mammals and plants from returning back to their native land, which drastically changes the vegetation and habitat of certain areas.
