Environmental Changes
Environmental change is a change disturbance of the environment most often caused by the human influences and natural ecological process. Environmental changes include various factor such as natural disasters, human interferences, or animal interaction. Environmental changes encompass not only physical changes, but also factors like an infestation of invasive species.
PHYSICAL FACTORS
Geology plays an important role in the environment. The most important geological factors effecting environmental change include volcanism, erosion and weathering.
Volcanism introduces new minerals into the soil as well as gases into the atmosphere. The introduction of minerals nutrients into the soil is one reason why volcanic soils are among the most fertile in the world. Volcanoes can also change the composition of the atmosphere by emitting gases such as carbon dioxide and Sulphur.
Plate tectonics causes volcanism. It also creates mountains and valleys. When mountains are formed through tectonic uplifting, this changes the gradient of slopes and can increase the amount of erosion from wind and water. The increase in erosion increases the amount of sediment and the nutrients that enter rivers, valleys, and oceans. This can have a significant effect on the local environment over time. A change in the availability of nutrients from erosion could cause a shift in an ecosystem.
BIOLOGICAL FACTORS
Introduction of new organisms can also cause significant environmental change. This includes invasive species. A famous case would be Christmas island where an introduction of yellow crazy ants has led to the disruption of the local ecosystem and threatens the local crab population. Another example is the introduction of Argentine ants to places all over the world. These ants are becoming major pests and are causing serious problems for the native ant populations that are vital to local ecosystems. Humans have probably been one of the most influential species in modern times in shaping the environment and causing environmental change. Humans are the cause of a growing mass extinction, the reduction in forests worldwide, and the rapid growth of a new biome, cities.

Do you now believe that our Environment is changing ?
Yes our environment is changing every second , we still continue having rains in October month :)
ReplyDeleteYes the environment is changing and not for the better
ReplyDeleteThe human interfere badly affect on the environment
ReplyDeleteYes Deepa, change is the law of nature. Change happens everywhere and happens constantly.
ReplyDeleteVery informative and interesting.
ReplyDeleteHuman interference is destroying our environment.the least we can do is reduce the use of Fossil fuels.
ReplyDeleteVery interesting
ReplyDeleteNice
