The invention of squid ink pasta and the rules for student to wear black shoes and socks in school are an environmental solution to stop all the squid ink flow into our sea and river. Squid ink is in black colour and this squid ink can be the colouring for cotton which is in yellowish white colour. If we want this cotton to produce white shoes and socks, we need to bleach this cotton. Bleaching is not environmental friendly since the bleach will go to our ocean and river. Our river and sea creature need a safe environment to grow. Hence, let's support black shoes and socks in school.
