Extinction is a natural part of Evolution. It may happen in many season, like because of human development and human needs(“dodo” is a great example of it). We can help birds to overcome those hazards is a great way to promote bird conservation before more species vanish.
WHY DO ANIMALS BECOME EXTINCT
Hunting: Many species have been hunted to extinction or to the point where they are critically endangered. One example of this is the American Bison. There were millions of bison in the Great Plains of North America until the arrival of the Europeans. Hunting was so intense that only a few hundred were left by the time the animals became protected. Fortunately, they have survived on farms and ranches and are no longer endangered.
Loss of habitat: One of the main threats to animals today is loss of habitat. This comes from the expansion of humans, especially from agriculture. As vast areas of land are cultivated to grow food, natural habitats are destroyed. This can destroy many of the cycles of life necessary for organisms to survive and for biomes to thrive.
Pollution: Pollution from humans can kill off a species as well. This is especially true in fresh water biomes such as rivers and lakes. Sewage and run-off from industrial plants can poison the water. When one species is affected, other species can die off as well causing a chain reaction as the balance of the ecosystem is destroyed.
Disease: While it’s unusual for disease alone to wipe out a given species—the groundwork has to be laid first by starvation, loss of habitat, and/or lack of genetic diversity—the introduction of a particularly lethal virus or bacterium at an inopportune moment can wreak havoc. Witness the crisis currently facing the world’s amphibians, which are falling prey to chytridiomycosis, a fungal infection that ravages the skin of frogs, toads, and salamanders, and causes death within a few weeks, not to mention the Black Death that wiped out a third of Europe’s population during the Middle Ages.
Some animals are considered extinct in the wild. This means that the only surviving members of the species live in captivity, like in a zoo.
Animals become extinct for a variety of reasons. Today many animals are endangered or have become extinct due to the influence of humans. Some of the ways that animals become extinct are described below.
SO HOW CAN WE SAVE THEM
GROW NATIVE PLANTS
It’s a no-brainer but local species rely on local plants. You are providing food and shelter for native wildlife and you can reduce your water usage at the same time. Attracting native insects like bees and butterflies can help pollinate your flowers. And conversely, invasive species compete with native species for resources and habitat, threatening biodiversity. They can even prey on native species directly, forcing native species towards extinction. For more information about native plants in your area
REDUCE YOUR WATER CONSUMPTION
During droughts, people get better about not watering their lawns, but we need to understand that clean water is a global problem for wild animals, so the less humans consume, the better. Never dump chemicals or pharmaceuticals down toilets, storm drains or into streams or lakes.
RECYCLE AND BUY SUSTAINABLE PRODUCTS
Much of what threatens local populations has to do with development and more and more of the natural world is plundered to product new goods. Never buy furniture made of wood from rainforests or endangered trees. Recycle your cell phones, because a mineral used in electronic production is mined in gorilla habitat. Don’t use palm oil because forests where tigers live are being cut down to plant palm plantations.
Lots of creatures are been extinct by humans, In many ways we have extinct. So please save them
