There are many reasons why animals and plants went extinct including lack of food. Loss of habitat was also a cause of extinction for animals and plants.
many river dolpinhs face extinction(in Asia one species was declared extinct) and so do many other species
It is true that endemic species face relatively high risks of extinction. An endemic species refers to a species that is restricted or native to a particular area or country.
Urban Growth and Desolation
An international team of scientists says it has found a "lost world" in the Indonesian jungle that is home to dozens of new animal and plant species. ... its face - the first new bird species to be sighted on the island of New Guinea ... undescribed plant species, including five new species of palms ...
Every animal is a part of the food chain, so mass extinction can have very bad consequences for the species that survive. The surviving species must learn to work around the animal that has recently become extinct.
Extinction occurs when a species completely dies out, while absorption happens when a species merges with another. Extinction reduces biodiversity and can disrupt ecosystems, while absorption may lead to genetic diversity. Both processes can impact a species' survival in the face of environmental changes by either reducing or increasing their ability to adapt and thrive.
Hunting is one action of man that is responsible for the danger that most species of plant and animal face. Building in natural habitats where plants and animals live is another action of man that puts plants and animals in danger.
Glaciers have significantly influenced plant and animal life by shaping habitats and altering ecosystems. As glaciers advanced, they carved landscapes, creating valleys and lakes, and when they retreated, they left behind fertile soil, allowing new plant species to colonize these areas. The dramatic changes in climate and environment also led to shifts in species distribution, forcing some animals to adapt, migrate, or face extinction. Additionally, the cyclical nature of glacial periods has contributed to the evolution of various species as they adapted to changing conditions.
Species can face extinction at any time due to various factors such as habitat loss, climate change, pollution, and overexploitation. While some species may disappear in the near future, others may survive longer depending on their adaptability and conservation efforts. Predicting a specific timeline for total extinction is complex, as it varies widely among species and ecosystems. However, ongoing biodiversity loss suggests that without significant intervention, many species could face extinction in the coming decades.
An animal might be hunted into extinction. Some of the last Australian thylacines were shot to death, though the very last one probably died in a zoo. The passenger pigeon was hunted into extinction. Disease can also wipe out a species. The Tasmanian devils are threated by a face cancer. An asteroid (or comet) impact may have wiped out the dinosaurs 65 million years ago. If an animal's food source becomes extinct, or the animal is driven from a key food source, that can cause it to become extinct. Competition for a food source can also lead to extinction, for example, if some other species devours all the food. It was once thought that the dinosaurs may have become extinct because little mammals ate all their eggs. Invasive species may step up competition for resources, driving native species to extinction. Also, extinction may be caused by a combination of these factors.
Kinfishers are not under the threat of extinctions . Only a few of the more insular species of the roughly 90 species of kingfishers are threatened with extinction. For example, the endemic Marquesan Kingfisher of French Polynesia is listed as "Critically Endangered" by the IUCN.
There are currently over 1,300 plant and animal species listed as endangered or threatened in the United States under the Endangered Species Act. These species face varying levels of risk of extinction due to factors like habitat loss, pollution, climate change, and human activities.
