Answer 1

The major causes of biodiversity decline are:

• Habitat loss, fragmentation, and destruction (affects about 73% of all species),
• Pollution and pollutants (smog, pesticides, herbicides, oil slicks, and GHGs).
• Climate change.
• Introduction of alien/exotic species.
• Overexploitation of resources (poaching, indiscriminate cutting of trees, overfishing, hunting, and mining).
• Intensive agriculture and aquacultural practices.
• Hybridization between native and non-native species and loss of native species
• Natural disasters (Tsunami, forest fire, earthquake,s, and volcanoes).
• Industrialization, Urbanization, infrastructure development, Transport - Road and Shipping activity, communication towers, dam construction, unregulated tourism, and monoculture are a common area of specific threats.
• Co-extinction.
