Brisbane: One of the most unfortunate effects of climate change is the impact it has on the species of marine life. University of Queensland researchers and global marine experts reviewed marine biology literature and categorised a wide range of threats – from climate change to pollution, to fishing – faced by more than 45,000 species and developed a framework. The framework has been formed for identifying the most vulnerable marine species. It will boost global conservation and policy efforts against anthropogenic climate change. The research has been published in ‘Ecosphere’.

Dr Nathalie Butt from UQ’s School of Earth and Environmental Sciences said the research revealed the most endangered species from all threats.
Molluscs, corals, and echinoderms – hard or spiny creatures such sea urchins – are truly feeling the impacts in our oceans, facing a diverse range of threats, Dr Butt said. They’re affected by fishing and bycatch, pollution and climate change.
“Flowerpot corals – an incredibly fragile but stunning form of coral found in the Pacific and Indian Oceans and the Persian Sea – is one group of species that is especially affected by climate change-related stressors, such as ocean acidification,” she continued.
We also discovered that starfish, sea snails and flying fish are increasingly vulnerable to climate change-related stressors, all of which can be found in oceans around the world.

“Roughy fishes are quite vulnerable to the effects of pollution, including organic, inorganic, and nutrient pollution, which was quite a surprise, as they live at a range of depths, including deep sea, which demonstrates how far the effects of pollution are spreading,” she said.
Dr Butt said the accelerating rate of environmental change was a motivating factor for the development of the framework.
The environment is changing so quickly because of human actions, and we need to use all information available to help us assess which animals are at risk and why, and to help develop the most appropriate ways to protect and manage them – that’s where this framework comes in, she said.
“This framework is unique as it uses biological characteristics or traits of marine species to assess their vulnerability to specific stressors or threats with the greatest potential impact, such as pollution, fishing, and of course, climate change.”

Fellow researcher Associate Professor Carissa Klein said this information would allow users to make more informed decisions about how to allocate and prioritise their resources to protect the world’s most vulnerable species.
Conservationists can use the framework to prioritise resources for their protection and determine which management actions would best protect particular species or groups of species and where, Dr Klein said.
She further added, “We assessed all species and all threats that we know about now across the planet.”
The exciting thing is that we built the framework so that we could accommodate new information, whether that be about new species or information about threatening processes. This means that the work can also be applied in particular places to protect the ocean, using more detailed information about the species, and their threats, in that place, she concluded.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, that is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
