Why can't we drink sea water

Aside from the fact it doesn't taste so well, it's a terrible idea to drink saltwater because it causes dehydration. Seawater is harmful to humans, since the body can not get rid of the salt from seawater. Through making the kidneys generate urine, the body naturally gets rid of extra salt, so it requires fresh water to dilute the salt in your body so that the kidneys can function properly. Seawater can be desalinated to reduce the amount of salt to where it should be palatable, but the process is very energy-intensive.

The Importance of Mangroves

Image
Mangroves are small trees which grow in coastal saline or brackish water. Having grown in a tropical peninsula by the sea I have developed a deep passion for mangroves not only for its beauty but more importantly because of its role in biodiversity. I love seeing colourful carbs growing up there, marine snakes, and all sorts of tropical fishes.  Considering the place were I am from there would be no hope for me but to love mangroves. These trees are just wonderful and perfect in every aspect. By the way this photograph was taken at Barra do Kwanza in Angola. Mangroves are evergreen forests found extensively in estuarine regions where the mud flats are wide and gently sloping. In addition to estuaries, they also live in intertidal regions of shallow bays and creeks where the environment is favourable to the growth of mangroves. Mangroves are a complete ecosystem, a conglomeration of many species of flora and fauna  in the area and their interactions with each ...

The Green sea turtle

Image
The green sea turtle (Chelonia mydas) of the Cheloniidae family is a genus of large sea turtle. It is the only species within the Chelonia genus. Its range stretches all over the world across tropical and subtropical seas, with two distinct populations in the Atlantic and Pacific Oceans, but is also present in the Indian Ocean.  Adult green sea turtles prefer to live near seaside grass beds, mangroves and coral reefs while younger ones live further away from shore. Green sea turtles are one of the largest turtle species in the world, weighing about 65-130 kg and ranging between 1-1.2 m in length. Animals have a thick shell of tear-drop shape, called a' carapace,' covering most of their body except for their head and four flippers. Their carapace can contain shades of various colours, including dark brown, green, olive, yellow, and black.  Chelonia mydas  is classified by IUCN and CITES as endangered and is protected from exploitation in most countries.

Spotted eagle ray

Image
Spotted eagle ray  The spotted eagle ray ( Aetobatus narinari ) is an eagle ray from a family of cartilaginous fish, Myliobatidae. Spotted eagle rays enjoy swimming in seas at a temperature of 24 to 27 ° C, and are more active in high tides. They are timid creatures who usually avoid humans, but they were seen jumping on boats and falling on people from the sea. Searching for their food, they dig their snouts into the sand on the seabeds. Groups of them consist of about 6 participants swimming at exactly the same speed in the same direction.
