The role of Rag-Pickers in saving the Urban environment

Rag-Pickers play a major role in saving the urban environment.None really pays any attention to contribute towards society.They collect the garbage and further segregate it.

This is a major health concern for them as it contains all sorts of germs.Due to their unawareness  and no education ,they are left with nothing but only this to do.The garbage that they collect has fine  glass pieces which many a times  injure them.

But to earn their livelihood,they have to bear all sorts of pains and injuries.They collect the house garbage and segregate the articles that can be recycled and sell them to earn their livelihood.

the remaining is disposed off.Virtually,in absence of rag-pickers,our surroundings will a  dumping ground of garbage. They are the unsung saviours of our environment.

River Pollution

Rivers are the biggest source of fresh water.They are therefore our lifeline for survival.It is really sad to see that most of our rivers are increasingly being polluted because of our negligible and irresponsibility.

Untreated sewage  and waste from industries  are continuously dumped into rivers.Religious ceremonies are also responsible for river pollution.Immersing idols and disposal of garlands and flowers end up in polluting the water.

Similarly,ashes after cremation are also poured into rivers.River pollution can pose a serious  threat to both the environment and  the human health.Continuos river pollution can disrupt the ecological balance and lead to the loss of biodiversity.

River pollution is thus a critical problem and the government must implement necessary steps to mitigate it.

Super -Earth,60 more planets found

Astronomers have found 60 new planets near our own, boosting the chances of finding one that could support life.

A team of International scientists  found  a further 54 potential planets ,meaning that in all the researches might have discovered  a full 114 planets.And at least some of those might be like Earth,and able to support life ,the researchers have said.

The observations were part  of the  Lick-Carnegie Exo-planet Survey,which was started in 1996 by astronomers  Steve  Vogt and Geoffrey Marcy from the University of California and Paul Butler,from  the Carnegie Institute of Science, in washington.

Astronomers released the largest ever compilation of exoplanet detecting observations made using a technique called the radial velocity method.The radial velocity method takes advantage of the fact that the planet’s gravity also affects the star.Astronomers  are able to use sophisticated  tools to detect the tiny wobble the planet induces  as its gravity tugs on the star.

The virtual mountain of data was gathered as a part of a two decade radial velocity planet hunting programme that uses a spectrometer called HIRES,mounted on the 10-metre Keck-I telescope of the WM Keck Observatory atop Mauna Kea in Hawaii.

The compilation includes almost 61000 individual measurements made of more than 1600 stars.By making the data public , the team is offering unprecedented access to one of the best exoplanet searches in the world.
