streams harmful human activity

Tundra - Tundra - Effects of human activities and climate change: Earth’s tundra regions are harsh and remote, so fewer humans have settled there than in other environments. However, humans have a long history in the tundra. The following discussion does not provide an exhaustive survey of all human effects but emphasizes those that are relatively widespread. Humans are known for their greedy and careless nature. Human activities have increased the abundance of heat-trapping gases in the atmosphere. Healthy streams and the fish and other organisms that live in them contribute to our quality of life. Among these, the most harmful one is the petroleum industry. This increase is mostly due to burning fossil fuels, such as coal, oil, and natural gas. To Effects of Mining Activities on Environment Mining is the extraction (removal) of minerals and metals from earth. Since more population means more land and more land means more destruction. Energy Industry: There are so many countries actively involved in the extraction, production and sale of energy. Water resources face a host of serious threats, all caused primarily by human activity. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources. How Human Activity Affects Soil Erosion Earth Science Erosion is the process by which rock and soil are removed from the surface of the Earth as a result of water and wind action and thereafter deposited to other areas on the Earth’s surface. It is caused by human activities inside homes, schools, offices, industries and cities that can spread across continent and even globally. Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water. 6. The range in human activities that affect the interaction of ground water and surface water is broad. Human effects can also result from activities within the watershed that indirectly affect streams by altering the movement of water, sediment, and contaminants into the channel. Human activities that has been destroying the environment for so long needs to be controlled now. Carbon dioxide has increased from a pre-industrial level of 280 parts per million to more than 410 parts per million today. Background levels of nitrogen and phosphorus are generally quite low and are normally measured in milligrams per liter. This is the contamination of streams, lakes, underground water, bays, seas and oceans by substances that is harmful to living things. For example, the first people who went to North America from Asia more than 20,000 years ago traveled through vast tundra settings on both continents. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminium ore), iron ore, gold, silver, and diamonds are just some examples of what is mined. Human activities commonly affect the distri-bution, quantity, and chemical quality of water resources. They include pollution, climate change, urban growth, and landscape changes such as deforestation. Deforestation, cropping, grazing, land drainage, and urbanization are among the land uses that indirectly alter stream processes. Nutrients are present naturally in lakes and streams, but human activity has greatly increased the amounts going into surface waters. Human Interference in nature.
