Great Barrier Reef Not Expected to Survive upto 2050
The increase of global sea temperatures causes a process called coral bleaching, this is where the coral effectively kicks out the algae living on it therefore getting rid of its protection against disease and its main food source, causing it to turn a pale white. This means that it is much weaker and will not survive for very long.
A panel of 15 scientists in Australia have stated that the world need to keep sea temperatures under a 1.2 degrees Celsius increase or the great barrier reef will not make it to 2050. However, at its current rate the sea temperature will increase by 3.7 degrees Celsius by 2050. Loss of this coral will lower biodiversity in reefs around the globe and this will consequently create holes in the food chain causing many species of fish and aquatic plants to die and perhaps the loss of coral reefs entirely.
It is important to help preserve these reefs by lowering things such as our electricity usage so that future generations can enjoy the magnificent coral reefs just as we have.
Primark Launches a Sustainable Cotton Line for the First Time
CottonConnect is a company that recently partnered with Primark in order to help them shift to more ethical trading practices. Primark did this as consumers have asked for more transparency on retailers. Primark are recruiting over 10,000 female smallholder farmers onto their programme to help produce cotton sustainably and to increase income to the farmers and the company themselves.
To prove that their new programme is sustainable, Primark have released these stats: there has been a reduction of pesticides by 53.5%; a 13.5% reduction in fertiliser usage and the water usage has been reduced by 12.9%. Hopefully other big-name brands will now follow Primark’s lead.
Extreme Weather Events Could Kill Over 150,000 a Year in Europe Alone by 2100.
Global warming will create a range of extreme weather events ranging from Heat waves to wind storms. Currently, 3000 people a year (between 1981-2010) are killed due to extreme weather events however but by 2071 its set to rise to 152,000 and 99% of these deaths are expected to be due to heat waves. Deaths due to flooding are also expected to rise from 6 a year to 233 a year by 2100.
They have assumed that global temperatures will have increased by around 3 degrees Celsius by 2100 due to the current rate of greenhouse gas emissions. Because of this, many scientists believe that these projections have been overestimated and that the death toll won’t nearly be as high however with the rate of global warming not appearing to be slowing down it can only be assumed this is what will happen but 2100 unless global warming is curbed.
