In February 2011 we travelled to Malaysia. I was surprised to see modern housing estates in substantial numbers during our first cab ride from the Airport to Kuala Lumpur. It seemed more reminiscent of the United Arab Emirates than of the poorer Middle East or of other developing countries in SE Asia. Our hotel was similarly well appointed.
A couple of days ago a story about sulphur-crested cockatoos went semi-viral, probably in an attempt to lift spirits during Sydney's new Covid-19 lock-down. It appears that some smart cocky worked out how to open wheelie-bin lids. That's not a surprise - see below. What is surprising is that others are copying him and the practice is spreading outwards so that it can be mapped in a growing circle of awareness. The cockies are also choosing the red (household rubbish) bins that may contain food, disregarding yellow (cans and bottles); blue (paper and cardboard) and green bins (garden clippings). Yet, now they have also been observed checking-out other potentially food containing bins.
One has even been observed re-closing the lid - presumably to prevent other birds getting to the food.
Back in the 1950's I was given a pet sulphur-crested cockatoo we named Einstein. I was in primary school and I didn't yet know who Einstein was. My father suggested the name - explaining that Einstein was 'a wise old bird'.

Carbon Sequestration Source: Wikimedia Commons
This illustration shows the two principal categories of Carbon Capture and Storage (Carbon Sequestration) - methods of disposing of carbon dioxide (CO2) so that it doesn't enter the atmosphere. Sequestering it underground is known as Geosequestration while artificially accelerating natural biological absorption is Biosequestration.
There is a third alternative of deep ocean sequestration but this is highly problematic as one of the adverse impacts of rising CO2 is ocean acidification - already impacting fisheries.
This paper examines both Geosequestration and Biosequestration and concludes that while Biosequestration has longer term potential Geosequestration on sufficient scale to make a difference is impractical.
