The average American male consumes 100 grams of protein daily — almost double the necessary amount. This overconsumption isn’t able to continue for long. Besides, there’ll be an extra 2.5 billion people by 2050. Therefore, the United Nations will need to increase as many as 70% food projects by 2050 to solve this problem.
To survive, we need to change the way we farm and eat. Experts say algae(藻类植物), which can offer lots of protein, could be a possible solution. Meat, which is our main source of protein, uses a lot of our limited resources, like water and land, not just for the animals but also to grow their food. But the green slimy algae that lives in oceans, ponds and aquariums can grow fast, is packed with nutrition and needs next to nothing to grow. It can even grow in a desert. That’s surely a big deal.
The wellness company iWi is now growing a type of algae on a large scale. The farm has green seas as far as the eye can see. The entire farm covers 900 acres, 98 of which is currently being cultivated and operates all year around.
The algae on the farm is grown in long ponds called “raceways”, and an engine constantly stir water to make sure the algae is exposed to the sunlight. CO2 and a tiny bit of fertilizer are then pumped into the water to help the algae grow.
The fresh algae grown on iWi’s farm is a far cry from the unpleasant taste in your mind. That’s because not all types of algae smell or taste like pond scum(浮垢). And the farm’s algae simply tastes salty and gives hope that people would willingly eat this.
“The protein we’re producing is not going to be green,” said Miguel Calatayud. “Our protein powders will be difficult to be noticed when added to other foods. It will be in every single food that you eat on an everyday basis. Algae is going to be part of a regular food chain for us. It’s going to be a great thing for all of us and for our entire planet.”

Satellite, hunger, stars, kerosene lamps(煤油灯), the Milky Way, the Cultural Revolution’s factional civil wars, a light-year, the flood… these seemingly unconnected things combined together and formed the early part of my life, which shaped the science fiction I write today.
As a science fiction writer who began as a fan, I do not use my fiction as a way to criticize the reality of the present. I feel that the greatest appeal of science fiction is the creation of numerous imaginary worlds outside of reality. I’ve always felt that the greatest and most beautiful stories were told by science. They are far more magnificent, grand, involved, profound, thrilling, strange, terrifying, mysterious, and even emotional. Only, these wonderful stories are locked in cold equations(方程式) that most do not know how to read.
There’s a strange contradiction: On Earth, mankind can step onto another continent, and destroy the civilizations through war and disease. But when they look at the stars, they turn emotional and believe that if aliens exist, they must be friendly and kind.
I think it should be the opposite: Let’s turn the kindness we show toward the stars to mankind and build up trust and understanding between different peoples and civilizations. But for the universe outside the solar system, we should be cautious. For a fragile civilization like ours, this is the most responsible path.
As a fan of science fiction, a considerable part of the science fiction I’ve read comes from America. The fact that American readers can now enjoy my book makes me both pleased and excited. Science fiction describes event of interest to all of humanity. It often describes a day when humanity will form a harmonious whole and I believe the arrival of such a day need not wait for the appearance of aliens.
