According to The Better India,he started studying a biodegradable polymer(生物可降 解聚合物)that was first formed and researched in the 1980s called PBAT.At the time,it was made with corn and potatoes.After identifying a suitable class of machinery to produce the PBAT bags in Gujarat,his speech on PBAT received nearly 100,000 in seed funding that allowed him to start the project.

"I am glad I am able to contribute my part.Not having a normal college life can be tiring sometimes,but in the end,it is all worth it.I feel content when I go back to sleep.But much more needs to be done to make India plastic-free,and I will continue to strive for it,”he adds.. 1.What is the primary focus of Mohiuddin's entrepreneurial efforts?

B While Matt Damon relied on potatoes cultivated in biowaste to survive in the hit film The Martian,the researchers say it is a humble desert moss(藓类)that might prove crucial to establishing life on Mars. Scientists in China say they have found Syntrichia caninervis-a moss found in the Antarctic and deserts-is able to bear Mars- like conditions,including drought,high levels 18 of radiation and extreme cold. The moss was able to regenerate under normal growth conditions after spending up to five years at -80C and up to 30 days at l96℃，and after exposure to gamma rays,with doses of around 500Gy even promoting new growth.The team then created a set-up that had similar pressures,temperatures,gases and UV radiation to Mars.It found the moss survived in this Mars-like environment,and was able to regenerate under normal growth conditions,even after seven days of exposure. "These experiments represent an important first step,but they do not show that the moss could be a significant source of oxygen under Martian conditions,nor do they show that the desert moss could reproduce in the Martian context,"McDaniel said."Implying that moss,or any other pioneering species,is ready to terraform (行星地球化)Mars,or any other outer planet,is an overstatement."Zupanska added. Dr.Wiger of Wageningen University also raised concerns,including that temperatures on the red planet rarely got above freezing, making outdoor plant growth impossible,while the new study did not use Mars-like soil."The mosses were treated under Mars circumstances for a maximum of several days and then regrown under Earth conditions on sand,he said."This,of course,doesn't show at all that they can grow under Mars conditions. However,Prof.Edward Guinan of Villanova University in the US described the study as impressive."This extremotolerant moss could promise to be a pioneer plant for Mars colonization,"he said,although he noted the moss would need water to grow. “We have a lot of things to do,”he said. grow on Mars.
