With the ever-increasing number of the world’s population, there is similarly a soaring demand for sufficient food.The population growth rate is hence driving the world to clear forests in order to create more room for agriculture. Humans rely on ecosystems to supply food and other necessities for a healthy human life. Many of these are primarily the result of human actions and include ecosystem and landscape changes, sedimentation, pollution, over-abstraction and climate change.. Human activities, especially agriculture, have led to large increases in the levels of nitrogen and phosphorus in the environment. Tour operators are tapping a huge and ever increasing demand to visit the Earth's last great wilderness. Introduced species and biodiversity. A number of forces continue to seriously affect our natural water resources. Conservation and the race to save biodiversity. In 1935, the word “ecosystem” was invented by a British ecologist Sir Arthur George Tansley, who depicted natural system in “constant interchange” among their biotic and abiotic parts. The combustion of fossil fuels, including coal, oil,and natural gas, is one of the largest contributors to human disruption of the nitrogen cycle. Various Human Activities That Affect an Ecosystem 1. The human activity most widely viewed as changing the planet is the burning of fossil fuels. Email. Fossil Fuels. What is a biodiversity hotspot? The carbon flows between the different reservoirs are illustrated in Figure 2 (taken from ) which distinguishes between the pre-industrial situation and subsequent changes (red numbers). Various human activities affecting the life of ecosystems we should avoid, if not based on sufficient knowledge about the ecology of good landscape ecology and awareness of the importance of ecosystem balance both types of freshwater ecosystems, marine ecosystems and forest ecosystems. Ecosystem is the environment where biotic/ living things live and interact with nonliving things/abiotic factors such as coral reef, forest, grassland, farm etc. In water, this overabundance of nutrients, a process called eutrophication, can fuel the excessive growth of phytoplankton and algae, which can sometimes have devastating consequences. Agriculture. Antarctica's clean air, water and ice of are of importance to science for understanding how the Earth's environment is changing both naturally and as a result of human activity. These activities have served to increase the amount of nitrogen biologically available in the environment. Flows disrupted by human activity. Human activities that threaten biodiversity. Human impact on ecosystems. Humans have destroyed a tenth of Earth’s remaining wilderness in the last 25 years and there may be none left within a century if trends continue, according to an authoritative new study. Certain human activities have had a devastating impact on ecosystems, however. 3. ... That destruction amounts to 50 million acres destroyed annually, much of which occurring in the Amazon rain forest. From pollution to overharvesting, the damage and exploitation of wildlife and natural vegetation by humans has left some ecosystems in bad shape. Human activities affecting aquatic ecosystems are more likely to disrupt natural patterns and processes because species do not have the ability to adapt to the rapid changes to their environment that can occur.
