There are myriads of resources that are limited in the earth, therefore if we are not concerned about this, all of the useful resources might disappear. Consequently, our world will have damage. However, human beings can avoid this tragic by actualizing environmental protection. Thus, our school ISB is also putting effort to benefit the world. The main environmental protection that ISB accomplished is that the soap for the students and teachers to keep their sanitary is an unusual soup which is foam soap. Firstly, foam soup reduces chemical reaction, moreover, it is also cheaper than the common soap we use in everyday life. Additionally, this foam soup not only saves 10% of the water to rinse but, also decreases the amount of packaging waste. To conclude, actualizing environmental protection is not difficult, nevertheless, it makes a big difference to the earth.
