HAZARD OF MICRO-PLASTIC

  World facing a new problem,micro-plastic pollution. Micro-plastic is small plastic pieces less than five millimetres long which can be harmful to our ocean and aquatic life.
By 2018 micro-plastic had been found in 114 aquatic species digestive tract and tissue. In invertebrates including crustaceans and crabs. This leads to consuming less food, thus less energy to carry out life function and results in neurological and reproductive toxicity.

  Plastic consists of carbon and hydrogen in the polymer chain and other chemical compounds such as poly-brominate di-phenyl (PBDEs) and tetra-bromobis-phenol A(TBBPA). Microplastics are classified as primary and secondary microplastics. Primary plastics are microbeads in plastic pellets, industrial manufacturer and plastic fibre in synthetic textile will directly affect living organisms. Secondary micro-plastic where the large size plastics are broken due to wind, wave, sunlight and heat.
  This micro-plastic looks like food for Aquatic species. This may lead to the extinction of species and reduce the ability to produce eggs and sperms for reproduction. These plastics remain in the gut of fishes and not move to tissues so the consumption of fish will not affect human health. Also, these micro-plastics are floating in the air cause respiratory problems.
  If micro-plastics are further breaking into Nano-plastic can penetrate cells and move into tissue and organ. This result in emerging of new diseases. The only way to safeguard the world from plastic is to recycle, reuse, reduce.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...

How did fruits get their names?

There is a variety of fruits in today's world. Each fruit has a name and the names are derived from foreign languages - modern and ancient. Some of these fruits have names that don't go with the fruit also. The name gooseberry has nothing to do with geese. It was originally called gorseberry. 'Gorse' in Saxton (a language spoken by early germanic people) means 'rough'. This fruit grows on a rough or thorny shrub. Just like the gooseberry, the fruit strawberry has no connection with straws. Strawberry is the changed name of 'strayberry'. The strawberry runners stray in all directions and hence the name. Peaches have been around for thousands of years. This fruit made its way to Europe when the Romans were around. The Romans called it 'persicum' meaning 'Persian apples. It was traded by the Persians during that time.  The national fruit of New Zealand kiwi was found in China. In other countries, it was called Chinese goo...
