5 Major Extinction Events in Earth’s History Earth has had many extinction events in its life time, but there are 5 events that have been named major events due to the extreme amount of species that were killed off due to the event. The events, in order from first occurring to most recent, are the Ordovician – Silurian Extinction event (450-440 MA), the Late Devonian Extinction (375-360 Ma), the Permian – Triassic Extinction Event (252 Ma), the Triassic – Jurassic Extinction Event (201.3 Ma), and
(Aloe dichotoma), Adélie penguin, North Atlantic cod, Acropora cervicornis and coral are either extinct or threatened of being so. The death of the last Golden Toad in 1999 (Bufo periglenes) in Central America marked the first documented species extinction due to the rapid climate variation. Climate change is referred to as a change in the statistical distribution of weather patterns, which lasts for an extended period of time, that is usually decades to millions of years. The climate
can lead to a possible extinction which brings extreme danger to not only other marine life, but to humans and the overall ecosystem as well. Shark finning/hunting must be strictly prohibited to prevent an otherwise inevitable extinction of sharks.
demonstrates how far humans have damaged the ecology with their wrong sanitation habits. The only directions where the plastic thrown into the ocean would end are washed back on the shore or sank to the deep sea, Dr. Alan Jamieson, a professor in marine ecology at Newcastle University in the UK, said. No other options These two places are the only destinations for the plastic, he said. The team analyzed all kinds of animals from the Marianas Trench, the deepest in the
which was about 56 million years from the end of the prior Precambrian to the beginning of the Ordovician Period. The Cambrian period is the beginning of a large difference in life on Earth. Before the Cambrian most of the life was very simple and unicellular. For the first time we began to see more multicellular forms of life. "The oceans became oxygenated. Although there was a lot of atmospheric oxygen by the beginning of the period, it wasn't until the Cambrian that there was a sufficient reduction
In 2011, one of the world greatest natural disaster struck Japan and Pacific Rim. The 2011 Japanese Tsunami affected Japan locally and the world globally negatively. Marine life, Global waste, and Power plant failures affected the world globally. While marine life traveled to North America, high radiation levels, and waste traveling across the globe were all caused by the tsunami and earthquake. Likewise, there was also local effects similar which consisted of human casualties, preparation for future
1.5 Natural Resources As the human population grows and our demand for natural resources increases, more and more habitats are devastated. Today, we may be losing 30,000 species a year – a rate much faster than at any time since the last great extinction 65 million years ago that wiped out most of the dinosaurs. If we continue on this course, we will destroy even ourselves. – American Museum of Natural History For last two centuries, general living conditions and human well-beings have significantly

Almost 70% of cruise destinations are in high biodiversity. For example, in Hong Kong, the noise produced by cruise ships’ engines, generators and propellers will affect the aquatic species like Chinese White Dolphins, so the species will become extinction (“Sustainable cruise tourism,” n.d.). Moreover, growing cruise tourism, which appeals more global travellers, can outbreak of diseases and spread out quickly like Norovirus and Legionnaires, gastroenteritis and other infectious diseases (Peter,
