1. Five ways that humans have contributed to a higher rate of species extinction today
The ways humans cause the extinction of species today follow the activities people engage in
against the environment. As a result, these activities bring about species migration that leads to a
reduction in numbers. Also, they lead to complete extinction due to living in unfavorable
habitats. Five major ways of human-related causes bring about the extinction of species.
According to IUCN (2016), the first way is the constant hunting and catching animals for food,
selling, or entertainment. The second way humans bring about the extinction of species is
through land-use practices. The clearing of land to do agriculture, create settlements, and
establish economic activities brings about animal and plant species extinction. The third way is
when there is the unintentional or intentional introduction of destructive predators, parasites, or
destructive diseases. One way this happens is through agricultural activities, where the use of
certain agricultural methods may destroy the species’ habitat. The fourth way is through doing
ecological damage. For instance, engaging in agricultural activities causes air, water, and soil
pollution. Consumption of food that comes from polluted air, water, and soil will lead to a
reduction and complete extinction of species. The fifth way is through human activities that
cause change to normal cycles of the ecological system. For instance, change in cycles of how
species grow from being offspring to becoming mature animals or plants that can reproduce. The
effect of the cycle creates a gap between the remaining generation and ones that survive to bring
forth the next generation.
2. The contrast in the classification systems of IUCN, SARA, and MESEA

The classification systems used by the International Union for the Conservation of Nature's
Red List follows a ten categorization method. According to The International Union for
Conservation of Nature's Red List of Threatened Species (2020), the first category is extinct,
which includes species that are no longer available at appropriate times, such as seasonal,
diurnal, and annual. The second category is extinct in the wild. The third category is critically
endangered, meaning it faces an extreme and high risk of undergoing extinction. The fourth is
the endangered species, which is facing a high risk of becoming extinct. The fifth category is
vulnerable, meaning it is facing extinction if it is in...
