Asteroids pose a threat to Earth through potential impacts, which can cause a range of damage from local destruction to global climate effects. While the probability of a large, civilization-ending impact is low, smaller asteroids can still cause significant damage to cities and regions. Fortunately, these objects are detectable, allowing for potential mitigation efforts.

Habitat overexploitation refers to the unsustainable use of natural resources, exceeding the capacity of ecosystems to replenish themselves. This can lead to a decline in biodiversity, disrupt ecosystem functions, and negatively impact human well-being. Overexploitation can manifest in various forms, including overfishing, overhunting, and deforestation, all of which can have severe ecological and economic consequences.

Invasive species are non-native plants, animals, or other living organisms that thrive in a new environment and cause harm to the existing ecosystem, economy, or human health. They are a major threat to biodiversity and can lead to habitat degradation, displacement of native species, and economic losses.

Habitat loss is the reduction or elimination of the natural environments where plants and animals live and reproduce, primarily caused by human activities. It’s a major threat to biodiversity, leading to species endangerment and extinction. The three main types of habitat loss are destruction, degradation, and fragmentation.
