Asia and the Pacific region have continued to remain the world's largest producer of fish. Various researchers have identified certain benefits of consuming seafood, which have caused greater demand for them. Apart from being ideal source of vitamins, fish is also rich in Omega 3 fatty acids, which can help prevent high blood pressure, cancer and heart diseases. Seafood also strengthen the immune system through their antioxidants.
Rapid advances in fishing technology have led to the dramatic increase over the last 50 years in how many fish we are able to catch. Most people in the fishing business now use factory ships, in place of fishing vessels. These ships are can stay at the sea for several weeks and they have all the necessary equipment that can be used to either freeze of tin fish that they catch using their hunting ships.
The factory ships need to get full before they can return to base and this has caused over a 7% growth in catches every year.

Explanation:
Million years ago, Earth had one supercontinent called Pangaea and surrounded by an ocean (Panthalassa).

Answer: Please refer to Explanation
Explanation:
Undernourishment
This is defined as being unable to take the required amount of food and nutrients for energy that the body needs per day. This has to have gone on for a year for it to be classified as Undernourishment.
Desertification
This refers to a situation where land that was once fertile looses that fertility and instead begins to become more desert like. This is very prevalant in the Sahel region of Africa and can be caused by droughts and inefficient farming practices.
Food Security
This is defined as the access to sufficient, safe, and nutritious food at all times needed to be able to sustain the human body by meeting the minimum amount of recommended energy that the body requires to function.
The Sahel is an area immediately south of the Sahara Desert. It is semi-arid in nature and is prone to prolonged periods of drought.
When this drought occurs it tends to cause soil that was once fertile to begin to turn into a desert like soil due to the soil not getting water for such a prolonged period of time.
When there is a lot of fertile land used for farming lost to desertification then the people in those areas cannot farm and get food needed to survive. This causes Food Security issues because people do not have access to food that they require to survive.
Should this happen and the people there go through Food security crisis, they will become undernourished as they are unable to take the recommended amount of food necessary.
