• B. Fears of a possible collision of a meteorite with the Earth in the near future in the manner it happened 65 million years ago that caused the mass extinction of many species including those of dinosaurs.
• C. Large scale cultivation of genetically modified crops in many parts of the world and promoting their cultivation in other parts of the world which may cause the disappearance of good native crop plants and the loss of food biodiversity.
• D. Mankind’s over-exploitation/misuse of natural resources, fragmentation/loss of natural habitats, destruction of ecosystems, pollution and global climate change.

The correct option is D Mankind’s over-exploitation/misuse of natural resources, fragmentation/loss of natural habitats, destruction of ecosystems, pollution and global climate change.

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The Sixth Mass Extinction, also known as the Holocene Extinction and Anthropocene Extinction, is an ongoing extinction event of species during the present era (known as the Holocene Epoch) due to human activity.
Scientists have observed that this extinction event is the serious environmental threat to human civilization.
Habitat loss and its degradation including pollution and invasion
of alien species, overexploitation of biological resources, and climate change are the major drivers for the sixth mass extinction
crisis.
