Since the start of the century, the International Union for the Conservation of Nature (IUCN) has declared 665 species either completely extinct or extinct in the wild. Here are four forest-dependent species that have vanished due to habitat loss in the last 20 years.
How many species does habitat loss affect?
When an animal loses the natural home or habitat that it needs to survive, its numbers decline rapidly, and it moves toward extinction. It’s estimated that 14,000 to 35,000 species are at risk of becoming extinct, and habitat destruction is one of the main causes.
How many species have gone extinct naturally?
Extinctions have been a natural part of our planet’s evolutionary history. More than 99% of the four billion species that have evolved on Earth are now gone. At least 900 species have gone extinct in the last five centuries. Only a small percentage of species have been evaluated for their extinction risk.
Can a species go extinct if its habitat is destroyed?
When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction.
How many animals are extinct due to deforestation?
According to recent estimates, the world is losing 137 species of plants, animals and insects every day to deforestation. A horrifying 50,000 species become extinct each year. Of the world’s 3.2 million square miles of the planet’s rain forests, 2.1 are in the Amazon alone.
How many animal habitats are destroyed each year?
The current rate of deforestation is 160,000 square kilometers per year, which equates to a loss of approximately 1% of original forest habitat each year.
What are the top 5 causes of habitat destruction?
The main causes of habitat degradation is pollution, invasive species, agricultural development, diminished resources, such as water and food, urban sprawl, logging, mining, destructive fishing practices and the disruption of ecosystem processes, such as altering the intensity and frequency of fires in an ecosystem.
Is it true that 99.9 of all species are extinct?
Of all species that have existed on Earth, 99.9 percent are now extinct. Many of them perished in five cataclysmic events. According to a recent poll, seven out of ten biologists think we are currently in the throes of a sixth mass extinction.

Convention on Biological Diversity concluded that: “Every day, up to 150 species are lost.” That could be as much as 10 percent a decade.
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 we lose when animals go extinct?
Habitat loss—driven primarily by human expansion as we develop land for housing, agriculture, and commerce—is the biggest threat facing most animal species, followed by hunting and fishing. Even when habitat is not lost entirely, it may be changed so much that animals cannot adapt.
