Sir: Our oceans are being destroyed. Billions of pounds of plastics are in our oceans harming and killing animals and their ecosystems. Plastic never goes away and if we do not reduce the copious amounts being put into our waters, then the oceans will be tarnished forever. Studies have revealed that over a thousand metrics tons of plastic enter our oceans every day, there is no excuse for us to let this happen. Millions of people purchase and use plastic bottled water, these disposable bottles are unessential, the same goes for plastic grocery bags, and they are dangerous to our ecosystems. By encouraging the use of reusable water bottles we can make a difference and cut back on the use of this toxic material. And as for plastic grocery bags, we can use paper bags or cloth bags. If the excessive use and disposal of plastic is not fixed soon, sea life will continue to suffer and our world’s oxygen will be depleted. We have to take matters into our own hands and regulate and prevent plastic waste before it becomes an issue. AIMAN FATIMAH Karachi Published in Daily Times, April 15th 2018.
