Endangered Species Endangered species is a broad issue‚ one that involves the habitats and environments where species reside and intermingle with one another. Some measures are being taken to help specific cases of endangerment‚ but the question I have is should the Endangered Species Act be strengthened. The universal problem cannot be fixed until us as humans protect the natural environments where endangered species live. The Endangered Species Act of 1973 is one of the most popular and successful

Invasive Species: Asian Carp Asian carps are different species of fish that originated in many parts of Eurasia. There are 4 different types of Asian carps‚ but the silver carp and bighead carp are mostly found in the Mississippi River drainage basin and Illinois River. The silver and bighead carp first came to North America from China in 1973. Being filter feeders‚ they were imported to remove algae and suspended matter‚ ultimately trying to improve water qualities in aquaculture ponds. However

This mass extinction is usually referred to as the K-T extinctions. The dinosaurs became extinct during the K-T mass extinction. To examine

ecosystem is continuously changing rapidly‚ mostly in the reason of human impact. Humans make huge impacts on the world and many of those impacts involves human-caused extinctions. Evidently‚ this has become a huge issue relating on biodiversity and there have been many extinctions due to global warming‚ pollution‚ hunting‚ etc. In addition‚ there are many conservation acts being placed on endangered species for protection and the species are placed out of their normal habitat in the wild.

The Asiatic lion (Panthera leo persica)‚ also known as the Indian lion‚ is a lion subspecies that exists as a single isolated population in India’s Gujarat State. It is listed as Endangered by IUCN based on the small population size.[1] The lion population has steadily increased in Gir Forest National Park‚ more than doubling from a low of 180 individuals in 1974 to a level of 411 individuals consisting of 97 adult males‚ 162 adult females‚ 75 sub-adults‚ and 77 cubs as of April 2010.[3] The Asiatic

Genetic drift is a change in allele frequency which can rise or fall over time. Genetic drift lowers genetic variation every generation. The strength genetic

Many believe that humans are the perfect species. Many believe that no other species in the universe can compare to the intellect and emotional stability of humans. Although this is the popular belief for the majority of the public‚ many philosophers say this is not the case. Humans are far from perfect and various authors and journalists‚ directors and philosophers exemplify how humans are flawed daily through their works. Alexandre Dumas and Homer are two particular authors/philosophers that not

Kolbert wrote The Sixth Extinction as an attempt to explain and give examples of what seems to be a 6th extinction event currently happening in the modern world. We have discussed and learned about five other extinction events throughout this semester‚ and Kolbert pushes this 6th extinction event as a new rapid extinction predominantly caused by humans. One of the underlying causes of this 6th extinction event discussed in the book is the mass killing of both animals and humans. Another underlying cause

Of all the species that have existed on Earth 99 percent have gone extinct and even fewer make it into the fossil record and a very small fraction of those that fossilize are actually found even partially complete. Even if all of them did fossilize many would be too hard dig for many of them. And also it is highly unlikely that most would be found complete‚ due to the number of natural disasters and processes that have happened from the animal’s death to whenever it is discovered.
