Extinctions and protecting species 5.2
The view of extinction
if we see a lower biodiversity that species is more vulnerable to extensions.
5 mass extinctions in history.
1 species per million is lost every year.
Background extinction is lower than speciation rate, unfortunately humans are a species that endangers others.
Island species are vulnerable because they have lower biodiversity and can die out by any disturbance.
There are more vulnerable species depending on certain factors like small populations, specialization and habitats.
Humans and their consequences
humans are the species that make such impact in extinction rates.
Humans have different ways of saving genetic information.
There could be a mass extinction in this century.
Law protection and treaties that support them
Convention on biological diversity
Signed by 196 countries.
USA didn't join this treaty.
Oil drilling, mining, off-roading and others are not regulated by laws in the US.
CITES is a multilateral treaty to protect endangered plants and animals. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature. The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975.
The International Union for Conservation of Nature is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education.
