 ANSWER: C

ANSWER: B

• Recently in Budget 2023-24, the Finance Minister has announced that India will eliminate the sickle cell Anaemia condition in a mission mode by 2047.

Current Scenario

• India is the second-worst affected country in terms of predicted births with SCA — i.e. chances of being born with the condition.
• Research and screening programmes have found that the prevalence of haemoglobinopathies — disorders of the blood — is more common among tribal populations than non-tribal communities in India.
• SCA is prevalent in communities residing in areas where malaria is endemic. The sickle cell trait thus gave an evolutionary advantage, offering immunity to some people during malaria epidemics.
• Prevalence of SCA is higher in communities that practice endogamy, as the chances of having two parents with sickle cell trait is higher.

About sickle cell anaemia

• Sickle cell disease (SCD) is a group of inherited (genetic) red blood cell disorders.
• Red blood cells (RBCs) contain hemoglobin, a protein that carries oxygen. Healthy red blood cells are round, and they move through small blood vessels to carry oxygen to all parts of the body. In SCD, the hemoglobin is abnormal, which causes the RBCs to become hard and sticky and look like a C-shaped farm tool called a “sickle.”
• It is transmitted by parents carrying a defective ‘beta globin’ gene.
• The sickle cells die early, which causes a constant shortage of RBCs.
• When they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious complications (health problems) such as infection, acute chest syndrome and stroke.

Cure

• SCA is a genetic disorder, making complete “elimination” a challenge that requires a major scientific breakthrough. The only cure comes in the form of gene therapy and stem cell transplants — both costly and still in developmental stages.
  • Gene Therapy: The DNA inside the haemoglobin gene is edited to stop the disease.
  • Stem cells Transplant: the bone marrow affected by sickle cell anaemia is replaced with healthy bone marrow from a donor.
  • Blood Transfusion: RBCs are removed from donated blood and given to a patient, but challenges include a scarcity of donors, fears around safe supply of blood, risk of infection etc.

Efforts by India to eliminate SCA

• The Indian Council of Medical Research and the National Rural Health Mission in different States are undertaking outreach programmes for better management and control of the disease. The Ministry of Tribal Affairs launched a portal wherein people can register themselves, in order to collate all information related to SCA among tribal groups.
• The National Health Mission guideline on Hemoglobinopathies also identifies “establishing services at the community level for pre-marital and pre-conception screening backed by genetic counselling services” as a strategy for addressing SCA.
• In the Budget, the Union Health Minister said the government plans to distribute “special cards” across tribal areas and the mission will receive funding under the National Health Mission.
• The mission will entail awareness creation, universal screening of seven crore people in the age group of 0-40 years in effective tribal areas and counselling through collaborative efforts of central ministries and State governments.

 ANSWER: A

• Underwater noise emissions by ships pose threat to Indian marine species, as per a study.
• The noise results in injuries and changes in their behavioural response besides a shift in their migration route much to their loss.
• The measurement of the ambient noise levels was carried out by deploying a hydrophone autonomous system around 30 nautical miles from the Goa coastline.

Highlights of the Study

• Increased UNE Levels:The sound pressure levels of UNE in the Indian waters are 102-115 decibels, relative to one microPascal (dB re 1µ Pa). (Scientists have agreed to use 1µPa as the reference pressure for underwater sound).
• The East Coast level is slightly higher than that of the West. There is an increase by a significant value of about 20 dB re 1µPa.
• Factors: major source is continuous shipping movement.

Impact:

• The frequencies of ships’ underwater self-noise and machinery vibration levels are overlapping the marine species’ communication frequencies in the low-frequency range of less than 500 Hz.
• This is called masking, which may lead to a change in the migration route of the marine species to the shallow regions and also making it difficult for them to go back to the deeper water.
• However, the sound that radiates from ships on a long-term basis affects them and results in internal injuries, loss of hearing ability, change in behavioural responses, masking, and stress.
  • UNE is posing a threat to the life of mammals like Bottlenose Dolphin, Manatees, Pilot Whale, Seal, and Sperm Whale.
  • The main form of energy for multiple behavioural activities of marine mammals, which include mating, communal interaction, feeding, cluster cohesion and foraging, is based on sound.

About Marine Sound Pollution

• Marine sound pollution is the excessive or harmful sound into the ocean environment. It is caused by a variety of human activities, such as shipping, military sonar, oil and gas exploration, and recreational activities like boating and jet skiing.
• It can have many negative impacts on marine life.

 ANSWER: D

About

• Sagar Parikrama is an initiative of Government of India in the sea across the coastal belt demonstrating solidarity with all fisherfolk, fish farmers and concerned stakeholders as a spirit of 75th Azadi Ka Amrit Mahotsav.

Objectives

• to resolve the issues of the fishers and other stakeholders.
• facilitate their economic upliftment through various fisheries schemes and programs being implemented by the Government of India such as PMMSY.
• to focus on sustainable balance between the utilization of marine fisheries resources for the food security of the nation and livelihoods of coastal fisher communities.

 ANSWER: C

• A recent study shows that tsetse flies produce volatile pheromones that control their mating behaviour and the dangerous diseases they carry. With climate change projected to expand the areas in which tsetse flies can survive, more humans and animals are expected to be affected by these diseases in the coming years.
• Tsetse flies are known to carry parasites called African trypanosomes.
• When the insects bite humans or animals, they transmit these parasites, spreading diseases such as African sleeping sickness, which can be fatal to humans, and nagana, a disease that affects livestock and other animals.
