For example, without bees, many plants and therefore our food, will not be able to be produced. Without birds, seeds will not be dispersed, and many trees will disappear. What happens
Which Era Ended With A Mass Extinction? Paleozoic Era What era was the last mass extinction? Cretaceous-Paleogene extinction – 66 million years ago The Cretaceous-Paleogene extinction event is the most recent mass extinction and the only one definitively connected to a major asteroid impact. Some 76 percent of all species on the planet, including all
When Did The Sixth Mass Extinction Begin? The most recent, 66 million years ago, saw dinosaurs disappear.

What happens to
What Are Reasons For The Acceleration In Extinction Rates In Recent Decades? In addition, the destruction of natural habitat due to climate change, pollution, urbanization, and deforestation has led to the death of many species. These events have caused the extinction rate to increase dramatically. What is accelerated extinction? We humans can be so destructive
What Are The 5 Causes Of Extinction? There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption. Through the activity, students will create a list of reasons why animals can become extinct. What are the 6 natural causes of extinction? Extinction occurs when species are diminished because of
What Are 3 Man Made Factors That Can Lead To The Extinction Of A Species? Human activities that influence the extinction and endangerment of wild species fall into a number of categories: (1) unsustainable hunting and harvesting that cause mortality at rates that exceed recruitment of new individuals, (2) land use practices like deforestation, urban
