In the years 1981-2002, over 60% of the anticancer drugs on
the market were produced from the genetic resources of our
biodiverse plants and animals (Newman, Cragg &. Snader 2003
p.1022).
Biological diversity exists everywhere on the planet.
However, the degree of diversity can be severely impacted by
natural events and human interaction.
Some of the most biodiverse ecosystems are the tropical
rainforests of South America, Asia, and Africa. These locations
have felt the effects of human impact and have been rendered far
less diverse than in past centuries. Humans have deforested the
Amazon basin for logging, cattle ranching, and agribusiness
(Urquhart et al. n.d.). Genetic diversity is vital to the health of
an ecosystem and the loss of biodiversity in this region is an
alarm to the sustainability of human existence. When a natural
disaster or human impact damages an ecosystem, this damage spreads
to affect other parts of the ecology. The loss of a single species
can lead to the loss of others that use it as a food supply. The
habitat may be taken over by a species that suddenly loses a
natural predator. The organisms responsible for feeding,
fertilizing, and recycling our planet can be lost because of small
changes to their environment.
Biodiversity is essential for the future of humans on this
planet. The minor changes in farming methods, development,
pesticides, and herbicides can have a lasting and disastrous effect
on our food supply. Alterations to rainforests can affect the
weather and climate of the planet (NASA). Introduction of
non-native species, such as the Salt Cedar in the western U.
