  • The COP 16 took place from 29 November to 10 December 2010 in Cancun, Mexico.
  • The Cancun agreement violated the rights of Developing countries still was applauded by the World leaders.
  • The Cancun agreement ignored ambitious targets of greenhouse gas (increase in global temperature cannot exceed 2°C and also recognises the need to review whether the world should try keep it below 1.5°C) reduction to arrest average global temperature rise below 2°C-the guardrail fixed by the Intergovernmental Panel on Climate Change (IPCC) to avoid any catastrophic impacts of the climate change.
  • As per the first-ever Global Assessment Report on Biodiversity and Ecosystem Services by Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem
  • Services (IPBES) nearly one million animal and plant species are under extinction due to extreme weather and climate collapse issues.

Antibiotic and Fatal Resistance

  • Antibiotic resistance is the resistance related to overuse of antibiotics also known as drug resistance. It is difficult to control it at the sametime.
  • During antibiotic resistance the effectiveness of drugs chemicals or other agents designed to cure or prevent infections get reduced.
  • Methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Enterococcus and multidrug-resistant Mycobacterium tuberculosis (MDR-TB) are some of the examples of bacteria that are resistant to antibiotics.
  • It has been predicted that nearly 10 million people will die of antimicrobial resistance every year by 2050.
  • As per the 2019 reports chemical residues released from pharmaceutical and personal care products are not only becoming a major contaminant of water bodies in urban areas but are also becoming a source of drug resistance in the environment.
  • Cattle for example harbour resistant bacteria that could pose a problem to humans who come in contact with them.
  • It has also been revealed that poultry meat could be churning out robust microbes that can render all antibiotics ineffective.
  • The Union Minister of Health and Family Welfare formulated the National Policy for Containment of Antimicrobial Resistance in March 2011.
