Persuasive Essay On Climate Change

Decent Essays
One topic that biologists are most interested in is the patterns of life on Earth. One of the ultimate questions for a biologist to answer is how do new species arise, and for what reasons do they disappear? Biologists all over the world are searching for answers regarding the rapidly diminishing amounts, and in some cases, extinction of many of Earth’s species. Scientists are coming out with results that show current anthropogenic climate change is the main culprit for Earth’s continuing loss of biodiversity. With estimations showing future continuing rapid decreases and losses in biodiversity, climate change is likely leading Earth into its sixth mass extinction. Across history there have been many cycles of change in Earth’s climate, whether it be cooling or warming, but today’s climate change differs greatly. Humans have influenced the environment so greatly that we are experiencing anthropogenic climate change. The combination of human activities such as habitat destruction, overfishing, and pollution has multiplied the problem and is causing a startling decline in Earth’s biodiversity. Biodiversity, the totality of Earth’s species, ecosystems, and genetic diversity, is at great risk if temperatures keep increasing. If global warming passes approximately 3.6 degrees Fahrenheit, the IPCC concludes that of the species assessed, 20-30 percent will have a high risk of extinction during the next century (Pearson 19). Many of Earth’s species will find it difficult to keep
