The research by the University of Southampton’s Coral Reef Laboratory shows that some corals exhibit a dazzling colourful display when they suffer bleaching due to warmer temperatures—to protect themselves.
The university’s scientists found that glowing colours in bleached corals act like a protective layer (similar to sunscreen) when symbiotic micro-algae are lost. The vivid colours are also a blinking neon sign that encourages the algae to return. The study suggests that corals develop extreme colouration within 2 to 3 weeks after exposure to mild or temporary heat stress.
NEW YORK, Jul 20 2020 (IPS)* – “We may all come on different ships, but we are in the same boat now,” Martin Luther King Jr once said.

20 July 2020 (UN Environment)* — There was a time when industrial agriculture seemed to be a panacea for a fast-growing world. Synthetic fertilizers, chemical pesticides and high-yield cereal hybrids promised to reduce hunger, accommodate growing populations and stimulate economic prosperity. Between 1960 and 2015, agricultural production more than tripled, resulting in an abundance of low-cost fareand averting global food shortages.
But not everything went as anticipated. Decades of industrial farming have taken a heavy toll on the environment and raised some serious concerns about the future of food production. “Efficient farming is not just a matter of production,” says James Lomax, a United Nations Environment Programme (UNEP) Programme Manager. “It is also about environmental sustainability, public health and economic inclusivity.”
