Obviously the consumers thereof either didn't read the label or don't give a fig about our precious earth.

Also collected were bread bags (yep go feed the ducks and leave the bread bag for them as well), and discarded homemade bongs.

I can't wait till the newly cultivated "pots" mature to see how many more we can collect, Mr Pettersson.

Oh, and the "Caution Wet Floor" sign was obviously placed there by OH and S as a warning to lake users to watch their step.

Also observed were quite a number of whole coconuts bobbing around the shoreline. They've been floating around for many months. I just wonder whether these were dumped by the same enterprise that discarded dozens of whole frozen chickens earlier last year, presumably due to a freezer malfunction.

The Labor Party and its leader, Anthony Albanese, deserve applause for the decision, albeit a little late, to aim for net-zero emissions by 2050 ("Labor adopts 2050 net-zero emissions", February 22, p20). However, apart from declaring that Australia "should be a clean energy superpower", as proposed by Professor Ross Garnaut in his book Superpower. Australia's Low-Carbon Opportunity, Mr Albanese has not revealed how this goal will be achieved.

There are some serious problems to be solved in reaching Labor's admirable goal. Carbon dioxide emissions can be countered by, for example, planting trees or establishing orchards. However, emissions of methane, which is between 28 and 84 times more potent a greenhouse gas than carbon dioxide, can only be countered by oxidation to carbon dioxide and water vapour in the upper atmosphere, which takes a decade.

Vast volumes of carbon dioxide are released into the atmosphere in the manufacture of cement, and only about half of this is reabsorbed by concrete as it sets. The fact that China used more concrete in three years of the 21st century than the US used in the entire 20th century indicates the enormity of China's carbon dioxide emissions from this source alone.

Achieving net-zero emissions will not be easy.

I'm delighted to be able to share that February 23 more than 800 Canberra locals joined Dementia Australia to walk or run at Lake Burley Griffin in support of people living with dementia.

I would like to thank the people of Canberra for their extraordinary show of support and community spirit during our Memory Walk and Jog event. From participants, to donors, to volunteers, I'd like to thank everyone who helped in any way to make this event such a resounding success.

An amazing $70,000 was raised, and these funds will be used to provide invaluable support services, education and resources for people impacted by dementia in the Canberra community, and across Australia.

In the federal electorate of Canberra there is an estimated 3,300 people living with dementia. With that figure projected to increase to about 9,600 by 2058, events like Memory Walk and Jog play an important role not only in funding support, but also in raising awareness of dementia.

Given the election results may have been skewed by corrupt practices, surely it is time for the Supreme Court to announce that the election is invalid and that we should have a new one. No other punishment is likely to deter governments from future corruption.

If that can happen, it may be in the nick of time. The proposed bill to outlaw satire of the sort used by The Juice Media, suggests that we are rapidly heading into a dictatorship.

I applaud the efforts of UnionACT to send out volunteers to "cafes, restaurants and shops" to raise awareness about wage theft and work rights.

Sadly, it is not just the private sector in Canberra that is involved in wage theft or the denial of work rights.

The public sector in Canberra, including the higher education sector, has been involved in suppressing work rights through "sophisticated" change management and other processes (referred to in Enterprise Agreements) for a very long time. If in doubt, I suggest you investigate the cases with Comcare and/or with the Fair Work Commission (FWC).

While "successful" settlements are listed in the FWC statistics, many of these settlements are workers losing their permanent jobs and walking away with a settlement rather than continuing to pay solicitors while not having employment.

What is happening in relation to work rights in Australia (and often under the radar) is a travesty of justice particularly in light of the fact that Australia sits at the "high" table of the International Labour Organisation (ILO).

The alternative to treating Canberrans' "perennial attachment to the use of private passenger vehicles" as a problem ('Canberra's love affair with cars - but now it's going diesel', February 14, p3) is to recognise that Canberrans are, and will continue, to resist attempts by the ACT government to bully them out of their preferred means of transport.

The correct response to this reality is not the Commissioner for Sustainability and the Environment's call for more attempts to force people into so-called "active transport". Instead it should ensure the ACT's transport infrastructure is suited to the preferred choice of residents.

The recent changes to the Cotter Road/Adelaide Avenue merge demonstrate that the ACT Government is capable of sensible, low cost infrastructures upgrades that improve the flow of traffic on public roads. What is the chance we might see more of this?

Professor Kate Auty ("Canberra's love affair with cars", February 14) is frustrated at the low percentage of trips made by bicycle.

Compare many cycle paths to the road next to them. Undulations are removed for cars but cyclists have to follow the topography, making tracks cheaper to build.

If the government put as much thought into designing cycleways as they do roads more people would consider using them.

Canberra was designed as a car city by the National Capital Development Commission.

It is not a European compact city, it is 60 kilometres from north to south. No-one in their right mind would think of cycling even half the distance unless they were Olympians. To visit friends in Weston takes me three buses and one hour and 20 minutes. It is 20 minutes by car. Who is ever going to take a bus for such a trip?

Andrew Barr needs to wake up to the reality of the size of Canberra.

First there was the termination of leases. Then the boarding up and fencing off of the shops. Next, months and months and months of dereliction, followed by demolition. And now after two years and 136 days we have nothing but a very large, ugly hole and silence. The "developers" of 44 Curtin Place deserve 10 out of 10 for community disruption and zero out of 10 for competent project management.

Re: "Pension Privilege" (Peter Cooper, Letters, February 14). If you live in the UK you get the pension related to the contributions made and regularly upgraded with inflation. If you live in Australia you get the appropriate level of pension for just one year. It is frozen at that level, no increases ever.

My dad retired with the full UK pension of six pounds per week. 30 years later, it was still just that.

Re: "Would you buy a used car off Andrew Barr?" (Letters, 21 February).

For Sale: Used tax system. Registered until October 17. Owned by the same family for 18 years, driven wildly by the son since 2011. After-market revenue supercharger fitted. Unused Henry/Grattan/McKell maintenance manual included in purchase price. Damage to the upholstery results in poorer passengers losing their wallets.

Why won't the PM tell us what his policy of inaction on climate change will cost?

The "Canberra couple quarantined at camp" (canberratimes.com.au, February 22) should be grateful they were flown to Australia at taxpayers' expense rather than criticising the standard of accommodation at Howard Springs. They did not have to accept the offer of the flight and could have taken their chances on the cruise ship with its "better" accommodation.

John Hurst ("Questions for Albo", Letters, February 22) needs to add one word to his first question. That word is "not". The right question is "How much will it cost not to achieve the zero carbon dioxide emissions by 2050?". Once you have the answer to that question everything else falls into place.

Re: "Greens call for domestic violence data to be public" (canberratimes.com.au, February 22). The routine publication of official data on domestic violence is a good idea. Ideally, it would refocus police attention towards truly serious matters, and away from the underwear drawers of female journalists.

Prior to formulating Canberra Airport's "master plan" it might reasonably be asked if citizens were "consulted" about implications which might include increased noise and air pollution, traffic congestion, more concrete surfaces, and increased water and resource demands? ("New runway plan as airport looks to open city to the world", February 21, p.1-2).

If Trent Zimmermann and a couple of his colleagues cross the floor we could have an Albanese government to tackle global heating and domestic violence.

Coronavirus developments in Australia suggest to me that one man's meticulous public health quarantine procedure is another man's recipe for infection spread risk.

Brave men would die to protect children. Cowards murder children.

Alex Mattea (Letters, February 19) should be careful what he wishes for. A fresh election may well result in a greater majority of our preferred government.

Religions may "preach love and understanding" (Judy Bamberger, Letters February 22), but they don't necessarily practice it. For example, many people have been killed for not conforming to the dominant religion.

Will the High Court remain "un-Enlightened"?
