POPSAboriginal Rock Art at Risk But the peninsula is also seeing increasing industrial activity, including a gas processing plant, a fertiliser factory and iron ore port facilities, making it the only place in Australia to feature on the World Monuments Fund's list of the most endangered sites. Smalldon believes the rock art has suffered since mining took off in the Pilbara, which holds some of the richest mineral deposits on earth, in the 1960s. "We had nearly one million panels of rock art," Smalldon said.

POPSA radical new idea could save the world’s ecosystems. Tickell proposes setting a global limit for carbon pollution then selling permits to pollute to companies extracting or refining fossil fuels. This has the advantage of regulating a few thousand corporations - running oil refineries, coal washeries, gas pipelines and cement and fertiliser works for example - rather than a few billion citizens.

POPSHome-grown veg ruined by toxic fertiliser Dow AgroSciences, which manufactures aminopyralid, has posted advice to allotment holders and gardeners on its website. Colin Bowers, Dow's UK grassland marketing manager, told The Observer that links to their products had been proved in some of the cases, but it was not clear whether aminopyralid was responsible for all of them and tests were continuing. 'It is undoubtedly a problem,' he said, 'and I have got full sympathy for everyone who is involved with this.'

POPSWorldwide sanitation goal with recycling system 2.6 billion people worldwide do not have access to sewerage. We can turn human waste into renewable energy and fertilizer. An Indian Doctor, has developed a system which will do this, and the system can pay for it's self, whille it helps combat global warming. It can the be used in countries like China, and India where sanitation needs to be improved. Nature can't keep up, but we can give it help, and get other practical advantages such as a reduction in the spread of water borne diseases, like Cholera, and diarrhroea

POPSCatalysis chemistry wins Nobel prize A Catalyst, can speed up a chemical reaction, without being used, so can be reusable. Sometimes speeding up a reaction, or modifying a reaction is just a matter of finding the right Catalyst and knowing where to look.

POPSPollution control and new technology an uphill battle Such inventions deserve encouragement and funding.....but in the end it is treating the symptoms, not the illness. The world's population is increasing at a rate that may prove unsustainable.....and it is unlikely that countries such as China will ever adopt these technologies due to the cost factor.

POPSGreenbox turns car emissions into bio-oil Carbon dioxide engine emissions are diverted through a Greenbox, where algae fixes the carbon dioxide, i.e. grows. The algae is then collected and processed centrally into biofuel. Great idea, if it works.

POPSOrganic food 'better' for heart That's great, but it would be better if they would make the food more accessible to the average person. In the markets near me, organic food is nearly double the price of inorganic. The average person shopping on a budget (ie. the majority of people) just can't afford that.

POPSSoils offer new hope as carbon sink Now we're talking! A strategy which really makes sense for everyone, except the makers of fertilisers. But we need the natural gas they use for other purposes anyway. Put this together with Terra Preta (see my next clip), and we might have a way of turning the CO2 nightmare to our advantage. This makes much more sense than carbon sequestration, for example.
