Answer:
If the oil spilled in the gulf would have been processed oil, it would be worse than a normal oil spill as these oils have a higher shelf life.
Explanation:
Oil spills happen when a large quantity of oil gets mixed with large water bodies like <em>sea and oceans</em>. The oil being denser than water floats on the surface and does not mix with the water. It forms a coating on top of the water.
The difference between processed oil and normal oil is that they are heated at very <u>high temperatures</u> and this results in oxidation which creates <em>free radicals</em>, which are not good for the body and its cells. Also they have a very long shelf life due to which they will remain on water for a long time.
When oil spills happen, the <em>wind</em> cause the spill to spread over the water surface, thereby engulfing a large amount of area. The major disadvantages of the spill are:-
- The oil gets stuck in the feathers of the birds who come by to dip themselves,
- Animals like whale, dolphins have blow holes for releasing water. the oil covers these holes and makes it difficult for them to breathe.
- The fur of animals like <u>seal and otter </u>gets mixed with the oil and can prove harmful to them as it gets them exposed to cold.
- The overall BOD of the water body decreases, and organisms which use sun rays coming inside the ocean suffer as these get blocked.
- Since processed oil has longer shelf life, a large quantity of animals will suffer and die.
Decomposition - bacteria helps to decompose dead organism , it's also used in food production
Biodiversity is crucial to the reduction of poverty, due to the basic goods and ecosystem services it provides. Globally, some 2.6 billion people worldwide draw their livelihoods either partially or fully from agriculture. More than 3 billion people depend on marine and coastal biodiversity, while over 1.6 billion rely on forests and non-timber forest products. Loss of biodiversity poses a significant threat to their livelihoods. Biodiversity must therefore be protected and sustainably used for achieving poverty reduction and sustainable development.
In order to link biodiversity considerations with poverty eradication and sustainable development, the environmental community and the stakeholders who specifically deal with the economic and social dimensions of development need a common framework, a common language. The concept of “ecosystem services” provides such a language as it describes “the benefits people obtain from ecosystems."
Ecosystem services include provisioning services such as food and water; regulating services such as flood and disease control; cultural services such as spiritual, recreational, and cultural benefits; and supporting services such as nutrient cycling that maintain the conditions for life on Earth.
The answer is C. The first option is highly unlikely, the second option is impossible, and C is a much more likely answer than D.
