Large open areas of grass or plants that are similar to grass are considered to be grasslands. The majority of time trees are not found in grasslands because grasslands tend to be too dry in an environment. Rainfall is the primary source of water, and the absorption occurs through the roots of the grass. The roots are extensive and yield multiple networks and modified photosynthesis. Multiplication of the grass occurs by pollen being excreted from wind or additional plants growing from the roots. During a ...view middle of the document...

One of the major benefits of grassland agriculture is protection. Grassland Agriculture protects soil from wind and water erosion, provides high quality relatively inexpensive feed for livestock and wildlife, as well as wildlife habitat. Grassland Agriculture maintains soil fertility because it encourages higher levels of soil organic matter that row crops. Maintaining grassland agricultural is crucial, because improper use of agriculture chemicals may have detrimental effects on grasslands. (Forages Information Systems, 2009).
No grassland is entirely natural and there are many degrees of interference such as fires, grazing by livestock, and large herds of wild herbivores. More invasive interventions have been clearing of woody vegetation either to give better grazing or originally for cropping, provision of water points to extend the grazing area or season, and various improvements techniques such oversowing with pasture grass and legume seeds (Food and Agriculture, 2015).

In light of the important relationship between agriculture production systems and the surrounding environment, the term grassland agroecosystem has been created. An agroecosystem contains both living and nonliving abiotic components. The living components consist of grasses, cattle, insects, and the nonliving components are made up of the weather, minerals or sunlight (Food and Agriculture, 2015).
The human population is increasing vigorously by the day. As the population grows, it has significant effects on the world’s ecosystems and its resources. The world’s water supply is one resource that’s affected and will continue to be. Fresh water is limited as it is, and the demand for it is increasing as the uses per capita increases along with the population. Along with water are the coastline and oceans. The growing population and urban development is threatening the coastal ecosystems. This is causing pollution in the oceans and, as a result, causing harm to life in the oceans. This is also why ocean fisheries are being overexploited, and fish catches are plummeting.

This world was made up of many forests, but today over half of them have been bulldozed or burned for expansion of cities and space for human life. Forests provide over US $400 billion to the economy and are vital to maintaining a healthy ecosystem. Destroying these forests for factories and other pollutions to the environment we could damage our ozone layers. Then we will have a huge problem on our hands. This also plays a part in the biodiversity of our economy. It is crucial to the world’s vitality of agriculture and medicine and maybe even life itself. Animal and plant species have and are becoming extinct thanks to human activities that are not healthy to the environment. There is an estimate of every two to three animal species to be on the decline. All of these problems will result in the overall climate change. The greenhouse gas emission, which are burned from fossil fuels are causing...
