Out of all the species that have ever existed since the beginning of time‚ 98% of them are extinct (Facts). There are an estimated 5-10 million species that exist currently and only 1.5 million have been identified (Sherry‚ 2). Scientists classify species into six different groups: plants‚ animals‚ insects‚ algae‚ fungi‚ and microorganisms (Today’s Situation). In the tropical rainforest alone‚ most species are disappearing at the rate of 1% a year (Sherry‚ 6). If the current trend continues‚ at least

aside one large issue that comes to mind dealing with ecosystem imbalance is invasive species. Most invasive species do not add or diminish from there new invasive ecosystem but sometimes they can cause a devastating effect on things such as population imbalance‚ predator versus prey imbalance and outright off balancing the entire ecosystem food web. The purpose of this paper is to discuss what an invasive species can do to an ecosystem and possible solutions to correcting the imbalance in the

LOSES OF BIODIVERSITY Some species that are more vulnerable to extinction than others include species at the top of food chains‚ such as large carnivores. Endemic local species which is a species found in only one geographical area with a very limited distribution‚ species with chronically small populations‚ migratory species‚ species with exceptionally complex life cycles and specialist species with very narrow requirements are also the examples species that are more vulnerable to extinction

Many species today are impacted by threats from changing environments. These threats can pose a great amount of harm to a specific species‚ which in turn‚ can ultimately cause it to be endangered. A species is considered endangered when a threat is relatively high and a population is rapidly declining in size. One of the most effective ways to identify an endangered species is through acknowledging habitat loss‚ introduced species‚ pollution‚ and overconsumption. This paper will investigate two endangered
