FYI, this is one of the major reasons to use digital wallets. Like Apple Pay and Google Wallet. They don’t use your actual card info when paying, but a generated virtual card instead.
Likewise one of my accounts provides both a physical card and a separate virtual card, so that’s what I enter whenever making online purchases. Easier to cancel and reissue a virtual card if there is fraud.
Not just more efficient, vastly more efficient. Algae is 10-50 times faster at processing CO² than trees are. Some algae can be up to 400x as efficient.
It’s just not as “nice” to look at, we usually associate algae with growth in unsafe bodies of water like bogs, etc. versus a nice clean pool or even a maintained pond.
