Antibiotic-resistant infections

Indiscriminate use of antibiotics is creating an epidemic like situation where antibiotics available today are not able to control infections. There is urgent need to develop new antibiotics urgently. Developments of new drugs are not easy due to the stringent requirements of clinical trials for adequate testing of the drugs for their effectiveness and safety. 

Millions of people die from infections (most often acquired in hospitals) which the existing antibiotics are not able to control. Saving a patient’s life is the primary concern of doctors. Options are very few. 

The governments, worldwide are very much concerned about the situation and millions of dollars are kept aside to support drug makers in developing new medications to combat the antibiotic resistance.

Due to the anxiety to develop new drugs (which are generally toxic), regulators should not approve new drugs without the required number of trials. Government health departments should come out with protocols to use such new drugs in a well-controlled manner.

World Environment Day (June 5)

Today’s Times of India quotes Mahatma Gandhi’s words: “Earth provides enough to satisfy man’s needs, but not every man’s greed”.
The news item gives details about the pollution status in a few Indian cities. The data are alarming to say the least! The major pollutant is suspended particulate matter (SPM). It has reached the critical stage, probably due to construction activities to accommodate ever-increasing population in urban areas. The carbon dioxide (CO2) concentration in the environment has breached a limit of 400 parts per million. It is one of the many Green- House Gases (GHG) emitted by industrial activities. Then, there is more GHG potent methane gas emitted by activities in agriculture. As per the UN Food and Agriculture Organisation (FAO), every year around 1.3 billion tonnes of food is wasted across the world! The ill-effects of the climate change, such as extreme climates, increase in the sea water levels, dead water bodies, depletion of forests, etc are seen  everywhere.

India launched 8 missions to counter climate change. No clear road map is available. Unless the missions are taken on war footing, nothing worthwhile is going to come out of these missions. 

Are we really awake? If we are awake then what we are doing to control global warming and to protect our environment?
