The Desert Ecosystem of Humans

Desert ecosystem of humans can be defined as the affect on the environment where human subsistence has altered the face of the environment to the extent that survival of a species used to the abundance of water is threatened.

DesertificationIn this environment the ecosystem can be a seen as being fragile where plants, insects, grasses, fungi and animals are in crisis. The survival of any species other than man, in the desertification shows an amazing ability to survive despite crippling odds.

The human created desert ecosystem may cause ecosystem disruption in an environment too harsh for the aquatic loving species of plants. Without the abundance of water many plants are unable to survive. Those that do survive have adapted or found themselves in a desert, sand-based looking piece of land.

A desert ecosystem can be seen in an environment where species cope with high levels of toxins in the water table. They may have adapted to harsh conditions. High diurnal range of temperatures due to the levels of human activity and building and environmental development make survival difficult for many animals, insects and plants.

Those that do survive in any number are often classed as vermin. Rodents are peculiarly adaptable and are often able to survive in a desert ecosystem of humans making. Cockroaches, rats, possums, ants, mosquitoes, flies, spiders are all able to adapt to this desert ecosystem. Plants that are able to withstand periods of drought, harsh treatment underfoot or under tires, are often so tough that they too are classed as weeds.

It is the ability to survive that makes those plants and animals numerous in a type that humans created. Cultivated gardens need care, and where lawns and manicured shrubs are able to survive with constant care, where as in the human depleted ecosystem only the toughest species survive.

In worst types of human made ecosystem it’s the humble survivor that forms the food chain. The hardy grass, the indestructible cockroach the every present fly can survive where humans exists. Those creatures and plants that are able to exist and propagate where life is toughest are the species that will thrive and populate.

Concrete, paving, tarmac and high density buildings alter the ground water flow and drainage of the landscape. With high volume run off, low volume absorption and with limited open landscape, grassland or trees, the overall consumption of water for the disrupted ecosystem is minimal.

Despite a high annual rainfall, much of the precipitation can be lost as storm-water. Having so much freshwater wasted makes a human desert type ecosystem. Species that once relied on abundant rainfall and absorption of run off must alter their areas of scavenging or leave the desert ecosystem of humans environment.
