what caused extinction of homo erectus? erectus likely went extinct due to climate change,” Ciochon added. “H. erectus was found with a collection of animal fossils that lived in an open woodland environment similar to the environment in Africa where it evolved.

What are the biggest threats to snow leopards? Hunting, habitat loss, retaliatory killings as a result of human-wildlife conflict, poaching and climate change are the biggest threats that snow leopards face. Snow leopard habitat range continues to decline from human settlement and increased use of grazing space.
Are the San Francisco Peaks active? Although there has been no eruption for nearly 1,000 years, it is likely that eruptions will occur again in the San Francisco Volcanic Field. With an average interval of several thousand years between past periods of volcanic activity, it is impossible to forecast when the next eruption will occur.

what extinct animals have been cloned?
A cloned Pyrenean ibex was born on July 30, 2003, in Spain, but died several minutes later due to physical defects in the lungs. This was the first, and so far only, extinct animal to be cloned.
are corals going extinct?
Each time, corals across the world’s oceans went extinct. Although there have been no recorded coral extinctions in recent centuries, a large number are still threatened with extinction today. The IUCN Red List of Threatened Species evaluates species across the world for their level of extinction risk.
what would happen if the great white shark became extinct?
The loss of sharks has led to the decline in coral reefs, seagrass beds and the loss of commercial fisheries. By taking sharks out of the coral reef ecosystem, the larger predatory fish, such as groupers, increase in abundance and feed on the herbivores.
are scientists trying to clone extinct animals?
But the very idea of de-extinction is somewhat misleading: Scientists say it’s not possible to really bring back an extinct species. Instead, scientists are planning to genetically modify an elephant to create a new synthetic organism resembling a woolly mammoth.

How does eating less meat help deforestation?
In best cases, this low intensity farming creates minimal soil interruption which allows the area to grow back through the help of the nearby forests and animals to bring energy, seeds, and nutrients back into the area.
Why is it important to prevent species extinction?
The Endangered Species Act is very important because it saves our native fish, plants, and other wildlife from going extinct. Once gone, they’re gone forever, and there’s no going back.
What affects the molar extinction coefficient?
The three factors include: The amount of light absorbed by the substance for a specific wavelength. The distance that the light travels through the solution. The concentration of the absorbing solution per unit volume.
Why did northern white rhinos go extinct?
Historically, uncontrolled hunting in the colonial era caused the major decline of white rhinos. Today, poaching for their horn is the main threat. The white rhino is particularly vulnerable to poaching because it is relatively unaggressive and lives in herds.
How does eating meat help the environment?
