Over the last 50 years, there has been an increase in the product and consumption of plastic globally. Our lifestyles, constant need for easily disposable products and the resulting waste has had a damaging impact on the environment. It is the accumulation of such waste, the kind that takes centuries to decompose, that has resulted in an increasing amount of plastic pollution around the world. Plastic pollution is associated with different types of harmful chemicals, the by-products of manufacturing and chemicals absorbed from the environment.
The amount of waste we produce is increasing and we have to go way beyond recycling and replacing plastic bags in order to deal with plastic pollution. We shouldn't underestimate the scale of the challenge we are facing; one that is formidable and is affecting us all in the four corners of the world. Plastic is an incredibly useful material and is widely used because it is inexpensive, versatile, durable and resistant to moisture, but it also contains toxic substances that cannot be broken down by a natural system, therefore making it indestructible in a biodegradable sense and with long- lasting effects that cannot be reversed. A terrifyingly large amount of plastic has been produced of which only a small amount has been recycled, some has been burned and the remaining majority has ended up in landfills or the environment. A large proportion of waste plastic ends up in the oceans. More plastic is being washed into the sea at a faster rate
affecting the marine life and causing problems for the environment and us. Hundreds of millions of tons of plastic is produced globally each year and much of it ends up in the soil or freshwater. Most of this plastic slowly fragments into small pieces which eventually end up microscopic but never truly go away. These microscopic particles, or microplastics, have potentially toxic effects on ecosystems.
Every piece of plastic that has ever been produced is still with us, in some shape or form. Recycling only converts existing plastic into reusable material, so we can't recycle our way out of the plastic pollution. Recycling will never stem the flow of plastics into our ecosystem; we have to get to the source of the problem.
It is undeniable that the ever-increasing amount of plastic waste will have an impact on the environment, but many are not concerned about the long-term issues it can create for the inhabitants of this planet. We have chosen to ignore the effect of our waste and plastic pollution on the planet as well as on our own lives for years, but it is time for a radical change. This is a global issue which requires collective action. Although some believe that it should be dealt with by governments, this problem can only be attacked when individuals and companies around the world work hand in-hand to reduce waste. More and more companies are starting to commit to plans to reduce plastic waste over the next couple of decades. As individuals, we also need to work towards a vision of a world free of plastic pollution by using reusable materials, avoiding using disposable plastics, and supporting initiatives to reduce the plastic footprint in our community. We should care and we should spread it like wildfire. Let's join the cause and make a difference!
