The toothbrushes are made up of 99% of plasticwhich have a life of more than 15 years, but according to doctors for good oral health, we should change our toothbrush once every 3, to 4 months, as the Google report says that about 3.5 billion toothbrushes are produced annually, which is about 70 tons of plastic. Unfortunately, when we change our brush, it goes to the Garbage. As these brushes can’t be reused due to their damaged bristles making their life short. This small part of brush has a large impact on the climate and earth. And if we tries to recycle it by remoulding, but this process also release harmful gases which can further lead to global warming. And when these gases will be present in a high amount in our atmosphere then it can cause many respiratory problems to humans. And not only to humans but global warming risk the life of "each and every organism on earth."
