Question

According to the graph, what are the three biggest threats to the biodiversity of the Mediterranean Sea?

(A) Aquaculture, invasions, and climate change
(B) Exploitation, eutrophication, and pollution
(C) Exploitation, habitat degradation, and pollution
(D) Exploitation, habitat degradation, and climate change
(E) Maritime traffic, eutrophication, and invasions

Answer 1

Hint: According to the graph, the three biggest threats to the biodiversity of the Mediterranean Sea can easily be calculated by seeing the height of the bars of different factors mentioned in the graph.

Complete answer: Habitat degradation, exploitation, and pollution are the biggest threats to the diversity of the Mediterranean. Most human beings for their own profit, overexploit the different types of fish species e.g tuna, etc. Many factories and industrial plants on the bank of the sea dispose of their waste directly into seawater causing the destruction of many coral habitats and pollute water and damage the ecosystem.

Additional Information:
The most common threat to biodiversity on the earth, is the combination of human increase and resource exploitation. The human population requires resources for their survival and to grow, and people's resources are being removed unsustainably from the environment. The proximate threats which were faced by biodiversity are habitat loss, overharvesting, and the introduction of exotic species. The primary two of those are immediate results of human increase and resource use. The third results from increased mobility and trade. A fourth major explanation for extinction, anthropogenic global climate change, has not yet had an outsized impact, but it's predicted to become significant during this century. Global climate change is additionally a consequence of the human population's need for energy and therefore the use of fossil fuels to satisfy those needs. Environmental issues, for example, toxic pollution, have specifically targeted effects on species, but they're not generally seen as threats at the magnitude of the others.

So, the correct answer is ‘Exploitation, habitat degradation, and pollution’.

Note: The famous Mediterranean sea was known to be an important route for merchants and travelers of ancient times, facilitating trade and cultural exchange between peoples of the region. The history of this very known Mediterranean region is very crucial to understanding the origins and development of many modern societies.
