For information on MLA format see the example below:
A forest eco system is a natural woodland which consists of plants and animals and microorganisms which all co-exist and depend off of one another in a non-living physical environment. As of late there are many threats facing forest ecosystems thanks to changes in climate and global warming. The otherwise perfectly functioning ecosystems are being harmed by things such as drought, invasive species, and human development.
There are many types of forests in the world. Given the diverse climatic regions forests are categorized by their elevation and their location (Hansen 161). The first major forest category is tropical. A tropical forest is near the equator and known for lush and dense forests. They store a large majority of the planet’s biodiversity. Sub-tropical forests are full of trees. They are found to the north and the south of tropical forests and can tactfully resist summer drought. Mediterranean forests are found to the south of temperate regions and consist of evergreen trees (Frame 51). Temperate forests can be found in Northeastern Asia, Northeastern Europe, and North America. They are made up of deciduous trees and coniferous evergreen trees. Coniferous forests are yet another type found in the poles. They are located in windy and cold regions and are full of hardwoods and conifers. The last type of forest is Montane. These are known as cloud forests and contain conifers. They are located in sub-tropical temperate zones (Forest Ecosystems 1).
Forests take up one third of the total land area in the United States. Affording many benefits forest ecosystems provide clean water, wildlife, carbon storage, recreation, and forest products such as wood (Elena 694). Climate influences the function of forest ecosystems and plays a vital role in the heath of a forest. Climate change is increasing the threats faced by forests by increasing the risk of drought, human development, fires, and pest outbreaks (Deforestation 1).
There are continued threats facing forests with increasing changes in climate due to global warming. As this problem persists forests will be prone not only to increased threats such as wildfires but the introduction of new invasive species which interfere with the natural processes of the forest ecosystem. This cannot be tolerated any further as forest ecosystems provide a vital part in maintaining the balance of the earth’s ecosystems and keep the air clean for living organisms including humans to breathe. In order to stop this destruction it is imperative that people take note of their carbon footprint and take the necessary steps to stop polluting the air and increasing the amount of carbon dioxide present.
