In addition to giraffes, bison, and camels there are also more deer than you'd find at a rest home on family visit day as well as zebras, exotic birds, and kangaroos. Just make sure you shell out for the corn because half the fun is feeding these incredibly friendly animals. I rarely write an absolutely glowing review of anything, but our experience at the Global Wildlife Center was perfect and exceeded every expectation we had. Biodiversity is all of the different varieties of species that inhabit the planet. Genetic differences within a species can mean differences in shape, size, smell, and color. Diversity of populations are "measured in both the number of individuals within a local group--the size of the loon population in northern Wisconsin--and
the distribution of a species' geographic range--the presence of loon populations from Alaska to Maine" (How Do Scientists Define Biodiversity). The variety of species within a natural community means
all the various species in a particular habitat. "A wide array of natural communities and ecosystems throughout the world, from tropical rainforests to tall grass prairies to boreal forests" make up the biodiversity of the world. Biodiversity is the natural make up of plants and animals of the world, and it should be valued highly. (How Do Scientists Define Biodiversity) Humans play a tremendous role in wildlife extinction. Habitat loss, degradation, and fragmentation are the leading factors that cause wildlife extinction to occur.
