Cold environments (both polar and tundra) are found in high latitude areas and mountainous regions of the world. They have an extreme climate and unique characteristics such as the soil type and the plants and animals found there.
Cold environments provide several development opportunities that can generate income, allowing the economy to grow. These development opportunities include: Mineral extraction - reserves of gold, silver, iron ore and copper can all be found in cold environments.
complex food webs are good examples of interdependence in cold environments. indigenous people rely on whales and seals for clothing, food and heating. Fish are a staple part of the diet of indigenous people. plants form dense cushions on the ground to protect them from wind and retain moisture and heat.
"Climate change is by far the worst threat to Arctic biodiversity. Temperatures are expected to increase more in the Arctic compared to the global average, resulting in severe disruptions to Arctic biodiversity some of which are already visible," warns Meltofte.
Both polar regions of the earth are cold, primarily because they receive far less solar radiation than the tropics and mid-latitudes do. Moreover, most of the sunlight that does shine on the polar regions is reflected by the bright white surface.
Polar habitats are located in the very north and very south of the globe – the two pole ends of the Earth. The northern polar region is called the Arctic, and in the south the polar region is the continent of Antarctica.
First, the permafrost prevents them from taking root, then those that do manage it have shallow root systems that are not an ideal anchor to withstand the high winds. Finally, low precipitation means there is not enough water to support trees. For most of the year, the tundra biome is a cold, frozen landscape.
Working in a cold environment can involve several adverse effects on human performance and health. Workers suffering from exposure to the cold can experience thermal discomfort, increased strain, decreased performance and cold-related diseases and injuries.
The tundra is a treeless polar desert found in the high latitudes in the polar regions, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as sub-Antarctic islands. The region's long, dry winters feature months of total darkness and extremely frigid temperatures.
Since bearberry is a low growing plant it can stay out of the wind chill. It's fine silky hairs also help to keep it warm. Leathery leaves are also an adaptation to the cold of the tundra. Bearberry is a very useful plant.
Plants have adapted to survive in extreme environments. Key factors include regulating temperature, conserving water and catching sunlight. They have adapted to exist in hot arid habitats.
Plants That Grow In Cold Weather
- Beets.
- Carrots.
- Turnips.
- Radishes.
- Cabbage.
- Collards.
- Kale.
- Spinach.
While crops have different levels or hardiness and cold tolerance, cold weather can still affect plants in the following ways: Water can freeze inside the plant's cells causing it to expand and destroy the plant from the inside. This can cause plants to wilt, even after the cold and frosty weather has done.
Striking a balance between economic developments and protecting cold environments can be achieved through careful management. Some of these management strategies include: Technology used to access minerals and fossil fuels should be managed carefully to avoid the destruction of wilderness areas.
Prevention of risks in cold environments can be done by planning of work, technical measures like heating or reduction of cooling by protective clothing, training and other measures.
Developing infrastructure for mineral extraction, fossil fuels or tourism is very difficult in cold environments. The following challenges can cause problems for development: Extreme temperature - very low temperatures and long hours of darkness make building very difficult.
Human effects include:gathering some Antarctic species to the skirt of elimination for financial advantage, murdering and upsetting different species, polluting the dirt, and releasing sewage to the ocean and leaving refuse, cairns and tracks in even the most remote parts.
A fragile environment is one which lacks resilience to change, meaning it is unable to adapt to variations that may arise as a result from human and physical impacts.
Antarctica is important for science because of its profound effect on the Earth's climate and ocean systems. Locked in its four kilometre-thick ice sheet is a unique record of what our planet's climate was like over the past one million years. However, Antarctica is fragile and increasingly vulnerable.
The tundra is a very fragile environment. The extremely cold temperatures makes it a difficult environment to survive in during the winter, and plants and animals have a hard time coping with any extra stresses and disturbances. Thousands of migrating birds come to the tundra because of the abundant insects.
The Environmental Protocol of the Antarctic Treaty, sometimes called the "Madrid Protocol", became law in 1998 after legislation in each of the member countries. One of the ways in which this protects Antarctica is by only allowing visitors to Antarctica by member nations as long as they are given a permit to do so.
