2/ The first giveaway that, despite their immense confidence, the Tweeter doesn't really know what they're talking about, is the claim that these algae units are to "be used in places where trees can't survive" is the healthy, mature street trees in both shots. 
2/ Yes, the same anti-LTN group who mocked me up as a slave master and encouraged their gormless acolytes to lodge complaints about my support for LTNs appear to have turned out to be the bunch of dishonest, malignant grifters I warned you about.
2/ Firstly, let's deal with Andrew's statement that I delivered the U.K's largest number of LTNs "on the basis that sat-nav apps were increasing the traffic on local roads."
2/ Not rubbishing @transportgovuk's data, but 1993 👉2019 miles driven on the U.K's roads annually increased by 100 billion. 70% came from cars/taxis, yet the DfT have not explained why their new estimates show just a 200 million mile increase in London in the decade to 2019. 
2/ What if I told you that photographs over a 54-year period since the reintroduction of beavers to Alberta, Canada, showed they were associated with a 900% increase in open water and a "damatic influence" on mitigating extreme #drought?
2/ Concrete, tarmac, and other hard and synthetic materials - think the astroturf pitch (car tyre dump) or plastic play surfacing your Council recently installed - accumulate heat throughout the day and do not begin to release it until the external temperature begins to fall. 
2/ So, you fill your watering can with tap/grey water - provided it's colder than the room temperature (which is very likely) then you go around the house and water your plants *with terracotta pots* until the soil is thoroughly wet. 
🔨It can take between 10 and 80 years for a new, energy-efficient building to offset the emissions created during the construction process. 
2/ As serious an environmental problem as sewage discharges are, it's the permanent loss of a very specific mineral carried in our sewage that poses the biggest threat of all. 
Volkswagen. Embarrassed of cars. 
2/ The Council in question is inviting people to apply for street trees, rather than developing its own plan. Since street trees can increase property prices by 15%+, such an approach risks unevenly impacting housing costs and driving gentrification. poverty.ac.uk/report-welfare…
What if I told you one study in Manchester found that shade from street trees reduced surface temperatures by an average of 12°C and that concrete surfaces shaded permanently by a bank of trees were cooled by up to 20°C in the summer? You wouldn't believe me. But it's true. 
Now, before frequent flyer vegans assail my mentions, please be aware that a) demand elasticity for food is lower than for flights; and b) a *year's* consumption of cow's milk (200ml a day) produces around 80% of the CO2 of *one* return economy flight from London to Berlin.
2/ Since WWII, the U.K has lost half its hedgerows - a staggering 300,000 miles. Although rates of hedge destruction have been reduced since the high watermark of the 1980s, losses are still occurring due to removal and mismanagement, with huge environmental consequences. 
2/ So, what do @clarksshoes get right? Elimination of petrochemical-based glues ✔️Efficient design of biodegradable upper, reducing material waste ✔️Minimal detailing, reducing embedded carbon from manufacturing ✔️Minimisation of dyes, reducing product's chemical footprint ✔️
