Meet the man who isn’t running to the supermarket to stock goods -- thanks to his tiny urban garden which has kept him in fruits and vegetables for nine months. This green-thumbed Italian who moved to London six years ago has grown so many vegetables during lockdown that he hasn’t been to the grocery store for any in nine months.

29-year-old artist Alessandro Vitale has grown chilli (辣椒) on his windowsill for years, so he was delighted when he moved into an apartment with a shared garden last year. He set to work transforming half the 8×5m garden area into a growing place, created a wall for vegetables out of recycled water bottles, and made planters and a greenhouse.

In his first harvest this year, Alessandro managed to produce an impressive 30 different kinds of vegetables, including cabbage, carrots, garlic, fennel, leeks, cauliflower, and broccoli. Alessandro got in an impressive 35kg of tomatoes from just six plants, and he’s picked 10kg of 17 different types of chilli. Eager to be environmental, Alessandro’s crops are 100% organic: He uses wild nettle (荨麻) from a park for pest control, and the fallen leaves to make fertilizer.

Alessandro said: “When I was a kid I used to help my grandpa out in the garden. I remember he would import chilli seeds from all over the world and he would have tones of plants.”

Though Alessandro works full-time 45 hours a week, as soon as he’s home he spends a couple of hours tending to the garden. “My favorite thing to make with is jam and sauces from the chillis,” he says. He now runs his own YouTube channel SpicyMoustache, sharing urban gardening tips and encouraging others to create urban green spaces.

An Ontario teen is making waves by turning old fishing gear into new treasures. Since last year, Natalie, 15, has been taking lost or thrown — away fishing nets and rope and transforming them into bracelets, rope art, mats, baskets and necklaces.

Last year, Natalie was working on an assignment for her science, technology, engineering and mathematics (STEM) class. As part of the assignment, she learned about “ghost nets”, which are fishing nets that have been left or lost in the ocean by people who fish.

“They have huge effects on our environment. They can kill coral reefs and many animals,” said Natalie. “46 percent of the Pacific garbage is ghost gear.” The Great Pacific Garbage is a huge collection of trash floating in the Pacific Ocean between Hawaii and California.

Natalie told her mom she wanted to do something to help. She got in touch with a handful of charities, including the Sea Protection Society and Coastal Action.

After getting some shipments of ghost nets and rope from those organizations, Natalie, with the help of her family, started turning the discarded gear into new artworks. “We've made bracelets, rope art, mats, baskets, and we've made necklaces, which also use beach glass in them,” she said. Natalie then started selling the artworks online, the crafty buying and selling website.

She donated all her profits-minus a small sum of change to cover supplies — to the charities that donated fishing supplies to her. She's also been donating all the income from her non-profit business, called Nautical Waters, to charity. Natalie said she hoped to continue her passion for ocean life, with plans to study marine biology in university.
