Having more wayside trees benefits urban environment
RECENT destruction of trees along some roads in Kuching for transportation development has really given me some perspectives.
Sir David Attenborough, in his book, 'A Life on Our Planet', presents a review of the natural world throughout the past 70 years.
According to him, 'the world is heading for disaster if no redemptions are taken now'.
Attenborough, who just turned 99 earlier this month, is hailed as the most active researcher and broadcaster of natural heritage, covering all parts of Earth, so he truly knows what he is talking about.
His 'no redemptions' statement reflects the global situation where human beings have destroyed vast areas of forests, grasslands, icebergs, and even the great reefs in Australia resulting from the rising temperature and levels of acidity in the environment.
There are now alternative energy options other than fossil fuel, which is regarded as a source of pollution and global warming.
In this respect, Sarawak is heading towards utilising hydrogen technology, as well as solar energy for electricity generation.
Having said this, it is known that leafy trees absorb carbon dioxide and in the process, release oxygen that rejuvenates air quality.
So, why don't we have more trees around the city, especially over the open spaces?
The authorities did plant some beautiful wayside trees around Kuching in the 1970s.
One of them is the 'Tabebuia rosa', or 'trumpet tree'.
I see this species, which is native to the Americas, as 'a gift of beauty to the world' with its bell-shaped blooms.
These majestic trees are planted across the tropics and the sub-tropics not only for their visual appeal, but for their environmental and ecological benefits.
In Kuching, they used dot along the Jalan Simpang Tiga near the Spring Shopping Mall, but recently, several of them were felled to make way for the ongoing Automated Rapid Transit (ART) project.
Fortunately, we have some other trees elsewhere in Sarawak.
The trumpet tree is a natural showstopper. The specular flowering display in hues of pink, yellow, purple and white, comes in dramatic bursts during onset of a dry spell in our weather.
This tree species plays a vital role in supporting biodiversity. The blooms attract bees, butterflies and hummingbirds that are crucial for pollination.
Additionally, it provides good shade for humans and birds, contributing to healthy urban and natural habitats, respectively.
The tabebuia contributes to environmental sustainability in several major ways: Air purification – like all leaf-borne trees, it absorbs carbon dioxide and releases oxygen, helping to combat climate change; Urban cooling – the leafy canopies provide shade, reduce the 'heat island' effect in cities, and lower energy consumption, and; Soil health – the deep roots help prevent erosion and improve water retention.
The tree is known for being drought tolerant and relatively easy to maintain once it is established.
This makes them an excellent choice for reforestation, as well as for planting in areas with low-water retention or environmental stress.
It is also a good timber tree, as it yields hard durable wood good for decking, furniture-making and the construction industry.
The tabebuia tree is more than just 'a pretty face in the landscape'. It is a symbol of resilience, sustainability and harmony with nature.
By planting and preserving more of this tree, we are not only beautifying our surroundings, but also contributing to the planet's ecological balance and well-being.
Another great species is the 'Jacaranda mimosifolia', native to South America especially Argentina and Bolivia.
The trumpet-shaped flowers are in vibrant purple or bluish lavender hues, and the leaves are fern-like bipinnate and offer light dappled shade.
The tree can grow up to 50 feet (over 15m) tall, and it is a fast-growing plant.
It is moderate drought-tolerant once it reaches maturity.
The jacaranda is, in my opinion, a great urban landscaping choice for the streets, parks as well as large gardens due to its large canopy and stunning flowers.
Happy Gardening!

ArcelorMittal (AMS:MT) Strong Profits May Be Masking Some Underlying Issues
Explore ArcelorMittal's Fair Values from the Community and select yours The market shrugged off ArcelorMittal S.A.'s (AMS:MT) solid earnings report. We think that investors might be worried about some concerning underlying factors. Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit. How Do Unusual Items Influence Profit? For anyone who wants to understand ArcelorMittal's profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit gained from US$1.5b worth of unusual items. While it's always nice to have higher profit, a large contribution from unusual items sometimes dampens our enthusiasm. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. And that's as you'd expect, given these boosts are described as 'unusual'. ArcelorMittal had a rather significant contribution from unusual items relative to its profit to June 2025. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power. That might leave you wondering what analysts are forecasting in terms of future profitability. Luckily, you can click here to see an interactive graph depicting future profitability, based on their estimates. Our Take On ArcelorMittal's Profit Performance As previously mentioned, ArcelorMittal's large boost from unusual items won't be there indefinitely, so its statutory earnings are probably a poor guide to its underlying profitability. For this reason, we think that ArcelorMittal's statutory profits may be a bad guide to its underlying earnings power, and might give investors an overly positive impression of the company. On the bright side, the company showed enough improvement to book a profit this year, after losing money last year. At the end of the day, it's essential to consider more than just the factors above, if you want to understand the company properly. Keep in mind, when it comes to analysing a stock it's worth noting the risks involved. In terms of investment risks, we've identified 1 warning sign with ArcelorMittal, and understanding it should be part of your investment process. Today we've zoomed in on a single data point to better understand the nature of ArcelorMittal's profit. But there is always more to discover if you are capable of focussing your mind on minutiae. For example, many people consider a high return on equity as an indication of favorable business economics, while others like to 'follow the money' and search out stocks that insiders are buying. While it might take a little research on your behalf, you may find this free collection of companies boasting high return on equity, or this list of stocks with significant insider holdings to be useful.

Those who invested in PPC (JSE:PPC) five years ago are up 641%
Explore PPC's Fair Values from the Community and select yours For many, the main point of investing in the stock market is to achieve spectacular returns. And highest quality companies can see their share prices grow by huge amounts. To wit, the PPC Ltd (JSE:PPC) share price has soared 535% over five years. If that doesn't get you thinking about long term investing, we don't know what will. Meanwhile the share price is 2.4% higher than it was a week ago. We love happy stories like this one. The company should be really proud of that performance! So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns. AI is about to change healthcare. These 20 stocks are working on everything from early diagnostics to drug discovery. The best part - they are all under $10bn in marketcap - there is still time to get in early. There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price. During the last half decade, PPC became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image). It is of course excellent to see how PPC has grown profits over the years, but the future is more important for shareholders. If you are thinking of buying or selling PPC stock, you should check out this FREE detailed report on its balance sheet. What About Dividends? It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for PPC the TSR over the last 5 years was 641%, which is better than the share price return mentioned above. This is largely a result of its dividend payments! A Different Perspective It's nice to see that PPC shareholders have received a total shareholder return of 44% over the last year. That's including the dividend. Having said that, the five-year TSR of 49% a year, is even better. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider for instance, the ever-present spectre of investment risk. We've identified 1 warning sign with PPC , and understanding them should be part of your investment process. We will like PPC better if we see some big insider buys. While we wait, check out this free list of undervalued stocks (mostly small caps) with considerable, recent, insider buying.

Ask learners if they want their driving test examiner to be ‘chatty'
Driving test candidates should be asked if they would like their examiner to be 'chatty' or 'formal' to boost female pass rates, a report commissioned by a Government agency has suggested. Transport research group TRL, which proposed the measure, said it would avoid examiners creating 'potential anxiety'. AA Driving School told the PA news agency that learners do not want to be examined by 'a sergeant major nor a comedian'. Records dating back to 2007 show males are more likely to pass the test than females. The annual pass rate for males has ranged from 47-55% in that time, while for females it is 41-48%. The TRL study on the gender imbalance commissioned by the Driver and Vehicle Standards Agency (DVSA) – which oversees driving tests in Britain – found the performance of male candidates is less affected by their examiner. Researchers heard evidence that females may be more likely to notice and interpret an examiner's behaviour and demeanour, and this may prompt 'self-judgment and worry about how they are doing', the study found. This was based on interviews with learner drivers, people who had recently passed the test, instructors and examiners. Among the interviewees, a successful candidate said their examiner was 'very down to business' with 'no pleasantries', which 'made me feel just a little bit more intimidated'. But an instructor said a 'really chatty examiner' could end up 'distracting the student', while an instructor said having a conversation with a candidate could 'slightly distract' the learner at a time they 'want to be 100% concentrating'. In the report's recommendations about how to reduce 'potential inequalities around gender', it noted that examiners' communication approaches can be interpreted in various ways by different candidates. It went on: 'Examiners could ask candidates at the beginning of the test what kind of communication ('formal', 'chatty') would put them in the best frame of mind for driving to the best of their ability. 'Such a change would enable examiners to remain focused on ability and outcomes but do so in such a way that does not introduce potential anxiety that is unrelated to driving competence in candidates.' Emma Bush, managing director of AA Driving School, said: 'It is probably asking a lot of examiners to act 'formal' or 'chatty' on demand. 'Candidates probably don't want a sergeant major nor a comedian examining them. 'What all candidates want is a reassuring voice and presence, combined with a fair and professional approach to the test.' The study found no evidence that the gender of examiners themselves has a direct impact on the test experience of a candidate. It noted that female candidates are more likely than their male counterparts to pass the driving theory test, which it attributed to females generally doing more preparation. Researchers found that arranging subsequent attempts at the practical test involves more money and 'effort' than for the theory test. 'This imbalance could be addressed through, for example, increasing the price and effort required for the theory test', the report stated. Steve Gooding, director of motoring research charity the RAC Foundation, said it is vital the test system gives 'everyone a fair opportunity to demonstrate their ability to drive, regardless of gender'. He went on: 'It is right that the DVSA should be looking to see whether biases are present, and doing something about them.' A DVSA spokesman said it is 'committed to equality, diversity and inclusion', and wants all candidates to 'receive the highest level of customer experience'. He added: 'This is an important piece of research by TRL and we're now reviewing the considerations put forward to reduce inequality in driver testing in Great Britain, and help us further develop the guidance available to learner drivers as they prepare for their tests.' The average waiting time for a driving test in Britain as of the end of June was 22.3 weeks. The DVSA attributes the backlog to an increase in demand and some people booking their test much earlier than before. Officials hope an increase in the number of tests being conducted will bring waiting times down.
