Why is it called KT extinction? As originally proposed in 1980 by a team of scientists led by Luis Alvarez and his son Walter, it is now generally thought that the K–Pg extinction was caused by the impact of a massive comet or asteroid 10 to 15 km (6 to 9 mi) wide, 66 million years ago, which devastated the global environment, mainly through a …
Why will amphibians go extinct? Habitat destruction, non-native species (predatory fish, bullfrogs, fungus, pathogens), climate change (alters temperature and water levels), pollution and diseases (especially chytridiomycosis, caused from the chytrid fungus) all have been shown to contribute to worldwide amphibian declines.

Extinction occurs when species are diminished because of environmental forces such as habitat fragmentation, climate change, natural disaster, overexploitation by humans, and pollution, or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
when did mammoths become extinct?
For millions of years, woolly mammoths roamed across the globe until they disappeared around 4,000 years ago. Their mysterious disappearance has commonly been attributed to humans, who would hunt the animals for food and use the mammoths’ remains to build shelters.
