Eco Burials & Protecting The Great Barrier Reef
Death is a messy business. In America alone, 1.6 million tons of cement and over 870,000 gallons of embalming fluid — commonly containing formaldehyde — are buried along with 2.5 million caskets every year.
“What you have here is a landfill … a toxic landfill,” says Glen Ayers of the Green Burial Committee as he looks around a traditional graveyard in Massachusetts.
Proponents of natural burial want to reduce the pollution and resource waste associated with funerals, which also includes burying masses of hardwood and steel.
One solution is to use eco-friendly biodegradable coffins made out of cardboard or even banana leaves. Campaigners also hope to increase the number of natural burial sites, where plots blend in with the natural surroundings. There are currently fewer than 40 in the US.
Russell Beard travels to Massachusetts to meet the people hoping to bid the world a green goodbye.
How it works: Fixing the ozone layer
Declared as "perhaps the single most successful international agreement to date" by former UN Secretary General Kofi Annan, the 1987 Montreal Protocol has helped protect life on earth. The treaty saw world leaders come together to stop harmful chemicals destroying parts of the ozone layer.
The ozone layer formed around the earth after aquatic bacteria began to release oxygen through photosynthesis 2.4 billion years ago. This protective layer keeps out the sun’s most harmful UV rays and helped life on earth to emerge from water onto land.
But scientist discovered a hole in the earth's ozone layer in the late 1970s and they soon realized that it was created by man-made chemicals.
Present in everything from fridges to fire extinguishers, chlorine based gases known as chlorofluorocarbons (or CFCs) were damaging the ozone layer, and as a result harming plantlife and exposing humans to a greater risk of skin cancer.
In this "earthrise" animation, we look at how the ozone layer works and how international action was able stop damage to the earth’s protective layer.
Australia's iconic Great Barrier Reef has lost half its coral since 1985 and around 40 percent of this is believed to be down to the venomous Crown of Thorns starfish.
Scientists believe that a combination of global warming and nitrogen-based fertilizers from on-shore agriculture may have created the perfect conditions for the coral munching starfish, which are breeding in massive numbers.
Tamara Sheward heads to the Great Barrier Reef to meet divers culling the starfish — a painstaking process in which the creature’s stomach and each of its limbs is injected with a dry acid.
She also meets Dr. Jairo Rivera Posada from James Cook University in Townsville, who has developed a potential new weapon against the starfish - a protein solution derived from Ox bile and which kills the starfish in just one hit.
In a busy market in the Ugandan capital of Kampala, a group of women gather to cook. While the dishes they prepare are traditional, the brightly coloured stoves they cook on are new.
The locally made Ugastove, which requires on average half the amount of charcoal of traditional cookers, saves money in reduced fuel costs, cuts carbon emissions and reduces deforestation.
Estimates say that by 2030, if we carry on as we are, the world will have only 60 percent of the water it needs. In India's Ladakh, rising temperatures are leading to glacial melt and water shortages in the mountains of the Himalayas. The Hashemite Kingdom of Jordan is also struggling as it experiences severe drought.
"earthrise" investigates the local solutions being developed in Ladakh and Jordan to help ease the increasingly worrying water problems.
