【简答题】
You may never connect the words “good” and “eco-friendly”with plastic.It’s time to do a rethink on that as we say hello to hemp(大麻)plastic.Traditionally,plastics have been made from petrochemicals,which are mainly poisonous.Plants,on the other hand,are also a source of cellulose(纤维素),which can be used to make biodegradable (生物所能分解的)plastic.As hemp happens to be one of the richest sources of cellulose,it is only natural that scientists will support its use,considering its ecological benefits. Hemp plastic is biodegradable and recyclable.If you thought being eco-friendly reduced its solidity,you couldn’t be more wrong.The hard level of hemp plastic can match that of regular plastic.Hemp plastic is resistant to heat;however,the most outstanding feature of a few varieties of hemp plastic is that they are flame resistant too.Finally,if Henry Ford could imagine creating a car with this material,we can perhaps believe that it indeed is“ten times stronger than steel”. It is a pity that with so many useful qualities,we don’t see hemp plastic being used in our everyday life,the way it ought to be.Hemp plastic can easily take the place of the exiting plastic in products like cell phone chargers(充电器),laptop covers,etc.Currently,hemp plastic is being used to produce audio(音响设备),video,toys,automobile parts and packaging materials. Hemp fiber is one of the strongest natural fibers known to us.As scientists keep looking for ways to solve the ecological damage that traditional plastics have caused,here is a material that can be produced to be 100% biodegradable.Hemp plastic is known to be several times durable as compared to polypropylene(聚丙烯)plastic,and it comes without all the health and safety threats,It really has long useful life. Plastics keep reminding us of the damage that we have done to our planet,all under the excuse of convenience.As hemp products have become a new choice into our daily life,Please take a green plan now and make your effort to protect the environment. 小题1:Plastics produced in the traditional way are______.
