change will cause the sixth mass extinction on earth. Since humans keep harming the planet‚ multiple animals have the possibility of becoming extinct over the next fifty years. Global temperatures are continuing to rise and our planet is becoming warmer. Coquerel’s sifaka (Propithecus coquereli) in the Madagascar is one of the several endangered animals that are predicted to soon become extinct. In fact‚ they have gone through a vast population reduction over the past 50 years. Coquerel’s are endangered

Many nations have laws offering protection to these species: for example‚ forbidding hunting‚ restricting land development or creating preserves. Only a few of the many species at risk of extinction actually make it to the lists and obtain legal protection. Many more species become extinct‚ or potentially become will become extinct‚ without gaining public notice. The high rate at which the species have become extinct within the last

In the book The Sixth Extinction the author Elizabeth Kolbert writes about the major problem our planet is facing. Humans are causing a new mass extinction. There have been five major mass extinctions in the past. Unlike the others this extinction is caused by humans. It is occurring at incredibly fast rate because of the climate change. She also mentions how increased hunting in the bird the great auk caused them to eventually die off. This book is about the negative human impact on this planet

End to Their Reign Introduction: About 65 mya almost three quarters of the animal and plant species on earth went extinct. This mass extinction is known as the Cretaceous-Paleogene (K-Pg) extinction event. The Cretaceous was the last period of the Mesozoic Era which is when dinosaurs lived from about 250 to 65 mya and the Paleogene is the first period of the Cenozoic Era that started about 65 mya which is the Era that we are currently living in. So the extinction event marked the end of the Cretaceous

Determining the Absorbance Maximum Wavelength and Molar Extinction Coefficient to Find the Molarity of the Unknown DCPIP Background Information: A spectrophotometer is an instrument used to help determine the absorption spectrum of chemicals. It does this by reading the absorbance of the chemical at different wavelengths. All chemicals absorb light in their own distinct way. This distinction helps to identify unknown chemicals. The absorption of light within a chemical is also very important because

Zoo Essay Reasoning for animal extinction There are many reasons for animal extinction in the wild‚ here are some of them: Some animals due to adaptive radiation can become more effective in hunting and reproducing which increases their chance of survival and their ammount of offspring which means the other animals become more prone to decline in numbers. However‚ there are reasons for animal extinction as a result of human action: Habitat Destruction – Animal Habitats are

This is a very serious issue and people need to start applying the ideas of McDonough and O’Connor as well as Bill Gates. Rachel Carson‚ credited by many to have brought the issues of conservation to the public eye‚ believed that “people care about the problem of sharing the planet with other species” and that increasing this awareness would be enough
