The Royal Botanical Gardens apparently have a very tight budget. They open at 7am, which is way too late for most of the city dwellers who would like to walk or run through the fabulous parklands as part of their daily exercise.
Over many years we have been told that the Gardens cannot afford to hire rangers who safe guard the precious plants. Apparently, plants do get stolen!!! (My sub-idea is please stop stealing plants from the Botanic Gardens!)
Instead of hiring expensive human labour, the Gardens should consider buying drones to monitor visitors. The drones would be equipped with heat sensor cameras to follow visitors, especially around areas where plants are most likely to be stolen.
The drones would also have small pumps with the ability to microinject a smelly and bright colored substance on the offenders. The substance would be non-toxic, but the smell and colour would hang around for a couple of days to make the life of the thief especially uncomfortable.
Scientists at Chongqing Jiaotong University in China have created a paste that's made from the same substance found in plant cell walls. It's made from a sodium carboxymethyl cellulose solution which creates support and protection for plants to grow. When the paste is combined with sand in an arid environment, it's still able to keep water and nutrients for growth. A project in a northern China desert saw positive results in just six months. Flowers and vegetables were growing in nearly 500 acres of sand with the new technology, which essentially makes the land fertile in an extremely hot climate. http://www.distractify.com/news/2017/09/25/Z1OEAxp/china-researchers-deserts-fertile-land
BirdLife South Africa is working to create new colonies of penguins at quiet beaches in Cape Town by using decoy penguin sculptures.Most seabirds breed in colonies and will only do so if they feel safe. The decoys fool birds into thinking that other birds are already breeding thereAfrican penguin numbers have been on a decrease over the last 60 years and the West Coast of South Africa have suffered the most. They have seen an over 60% decrease in the last 20 years due to decreases in the availability of their preferred prey, which is sardines and anchovies.www.goodthingsguy.com/environment/decoy-penguins-new-colonies/
In a breakthrough in the war on climate change, CSIRO is on the cusp of commercialising a seaweed product, which when sprinkled into feed, makes cattle grow faster and cuts their greenhouse gas emissions to near zero.The super seaweed carries with it the potential to make the under-fire livestock industry carbon-neutral well before 2050, while also helping to feed a growing global population using less resources.CSIRO is weeks away from releasing a prospectus as it seeks big investors in an internationally significant discovery that cancels out methane emissions from cattle, and, as a bonus, has the waste in digestion – normally associated with burps and farts – converted into faster growth rates.www.afr.com/companies
