How do tundras affect humans

Nearly one-tenth of Russian territory is tundra, a treeless, marshy plain. Some scientists travel to tundra regions to study climate, wildlife and other subjects. One way humans can have a positive impact on the tundra biome is by avoiding hunting the animals that inhabit the ecosystem. Without plants to contain the soil, the earth quickly erodes and threatens to destroy the entire biome.

In addition, research indicates that the retreat of sea ice would enhance the productivity of tundra vegetation, and the resulting buildup of plant biomass might lead to more extreme events such as large tundra fires. Posted on April 22, Human Impact - Negatively. New towns and roads are being built to support the increased … Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

On January 3, , Alaska gained statehood along with its natural resources. Human Influences Positive and Negative As with many forests, the taiga biome is in danger because of deforestation. In contrast, greater plant productivity resulting from a longer, warmer growing season could compensate for some of the carbon emissions from permafrost melting and tundra fires.

For example, in the 's, humans were hunting so much that the animals were becoming endangered. Other changes occurring in both Arctic and alpine tundras include increased shrub density, an earlier spring thaw and a later autumn freeze, diminished habitats for native animals, and an accelerated decomposition of organic matter in the soil. Solutions to the Tundra biomes crisis can be as simple as writing up a poster or bringing up the subject in a conversation with your friends and family.

Some climate models predict that, sometime during the first half of the 21st century, summer sea ice will vanish from the Arctic Ocean. The tundra biome is a fragile environment so the things that humans have been doing to it can easily affect it. Tundra fires release CO2 to the atmosphere, and there is evidence that climate warming over the past several decades has increased the frequency and severity of tundra burning in the Arctic.

This kills animals, and if we hunt excessively the animals will become endangered. The smallest stresses can cause destruction on the biome and its flora and fauna. Oil Drilling: Tundra has many natural resources, like oil and nickel.

Clear-cutting may damage long-term forest productivity. Pollution particles, gathering in thick clouds, can also be absorbed by the plant life, contaminating the food source for animals in the region.

In the past 50 years, we have begun to see big changes in the How do humans impact the Tundra biomes? Eventually, governments began to recognize the issue and responded by enacting laws to protect the tundra animals. One of the most striking ongoing changes in the Arctic is the rapid melting of sea ice.

What is the impact of humans on Tundra? Warming temperatures could disrupt the cold tundra biome and the life in it, as well as thaw its underlying permafrost, releasing greenhouse gases that would further accelerate global warming. Animals that inhabit the tundra include large mammals like polar bears, Arctic foxes, Arctic wolves, caribou, elk and grizzly bears.

Small mammals such as marmots, Arctic ground squirrels, ermine and lemmings also thrive. Many bird species live in the tundra biome including both migratory species and year-round residents. Examples of tundra birds include snow geese, snowy owls, ptarmigan, Arctic terns, golden plover, loons, ducks and a variety of songbirds and shorebirds.

Humans have been living in the cold, harsh and remote tundra for many thousands of years. The presence of humans on the tundra can be traced back at least 20, years to the human migration from the Asian continent to the North American continent which occurred mostly in tundra habitats. Over centuries of living on the tundra, human activity has increased dramatically and the tundra landscape has been changed drastically by residential and industrial development.

On the tundra, human activity includes residential, recreational and industrial uses Many of the permanent residents of tundra regions are indigenous people, such as Alaska's Aleut and Inuit tribes, and rely on subsistence hunting and gathering in order to survive.

Recreational opportunities such as hunting and wildlife viewing are available for visitors to the tundra. Activities of the oil, gas and mining industries have been a subject of controversy as this type of human activity on the tundra causes damage to the delicate tundra ecosystem. The Arctic tundra, because of its low population density, amazing wildlife and glorious vistas, is a very popular destination for visitors from all over the world.

People travel to the tundra to enjoy activities such as:. Animals such as the polar bear, grizzly bear, Arctic wolf and caribou, as well as migratory birds of all sorts, make the Arctic tundra a fascinating destination for outdoor recreational activities.

Recent human impact on the tundra has been damaging and disruptive. The delicate, small plants that grow on the tundra are very easily disturbed. Some tundra plants grow extremely slowly, and because of the already short growing season, these plants have a very hard time recovering from disturbance. Permafrost provides the structure for many tundra habitats, and is very easily damaged especially during the summer thawing period.

Human activities and development in the region can result in many negative impacts to the ecosystem. Major threats to the tundra biome and wildlife include exploitation of resources, overhunting and climate change. Human impact in the tundra biome is most obvious in the exploration and development of mining, oil, gas and other extractive industries.

Due to slow vegetation growth, clearing for oil fields, pipelines, roads and other infrastructure leaves soil exposed for considerable periods of time. This significantly reduces biological activity and increases the rate of erosion.

Run-off from erosion, often exacerbated by altered hydrological systems from drains, culverts and the de-watering of mining pits, can also smother and otherwise impact vegetation further afield. The extraction and transport of oil and the use of toxic chemicals in mining operations can lead to the release of these pollutants into the Arctic environment. The muskox has been hunted by Arctic peoples for thousands of years, but by the early twentieth century modern hunting had wiped out the species in Alaska, Europe and Russia and significantly reduced their population in Canada and Greenland.

A ban on muskox hunting and reintroduction efforts have helped this species recover, but their range and population remain significantly reduced from their historical levels. Although not actively hunted to a significant extent, polar bears may be killed when they come into contact with humans. Climate change is increasing the frequency of these events, as hungry bears search populated areas for discarded food and other edible materials.

Atmospheric emissions from human activity can impact the delicate Arctic ecology. Black carbon fumes from diesel engines, fires and other forms of combustion can settle on snow, causing it to absorb more solar energy and melt at a faster rate.

This can particularly affect animals that rely on snow cover for shelter, such as small rodents, or for camouflage, as do polar bears, Arctic foxes and Arctic hares.
