Human Impacts on island ecosystems. (Australia) There are few paleovegetation records in Australia before 18‚000 years ago. To find out the history of the Australian fauna scientists used stable carbon isotopes from the emu eggshell (a flightless bird native to Australia). The samples were largely taken from Lake Eyre. The carbon composition of the eggshell tells us the composition of the bird’s diet (over 3-5 days). The emus are mixed feeders herbivores‚ eating leaves‚ shoots‚ fruits‚ flowers

Why should we care about deforestation? Deforestation is a leading cause in global warming and the increase in greenhouse gases like carbon. Deforestation also affects many things including man-kind. The degradation of the Amazons trees and vegetation would be oil industries‚ and soybean farmers’ expansion into the rainforest. The effects are also important as well‚ some effects of Deforestation are the change in climate‚ the impact on the global hydro climate‚ and scattered rainfall; whether it

The !Kung bushmen of the Kalahari Desert in Southern Africa are one of the few bands of hunter-gatherers left in the world. They survive by foraging for their meals while traveling‚ never settling in one specific area. Hunting and gathering was the primary mode of survival until about ten thousand years ago. Anthropologists have made assumptions about the hunting and gathering lifestyle of current populations because it seems like a precarious method of living. Moreover‚ the Kalahari area where

It is clear that salt‚ also known as sodium chloride‚ should no longer be used on our roads in the winter months. The first two reasons why salt needs to stop being used are because salt negatively affects aquatic ecosystems and causes damage to vegetation. The third reason is because thankfully‚ there are alternatives that we can use‚ that would be benefiting us which we should use instead of sodium chloride. To begin with‚ sodium chloride is detrimental to our aquatic ecosystems when it is used

The large area of the sage-steppe ecoregion opens up for varying fire intervals due to topography‚ landscape context including vegetation‚ and fuel continuity (Bunting‚ n.d.). Fire intervals range from decades to centuries‚ with a productive fire regime ranging from 15-25 years (Bunting‚ n.d.; Veblen et al‚ 1999). Both fire frequency and fire size have increased in the latter half

this plant has the potential to reduce flora and fauna diversity throughout the ecosystem that is exposed. Infestations are likely to destroy natural habitats of of organisms which is bad for the environment because it threatens the life of native vegetation. This is done by causing them to competes with the Hygrophila which ultimately causes them loose all nutrients and die off. This is caused through the degrade‚ reduction and loss of oxygen in the water quality.(source) why is it a problem to plants
