As the number of people on Earth increase, naturally, we need more resources to satisfy everyone’s needs and wants. With the current population at 7.4 billion, which is only increasing as the days pass by, we cannot expect to utilize lesser number of resources. We need more land, more water, more food, more oil, more factories, etc. Naturally, this means that more waste will also be generated. Let’s understand what happens to the waste that we add to the environment.
Waste generated by us:
In our day-to-day activities, we generate a lot of rubbish. Let’s look at some things that are thrown away by us.
Some more things include empty medicine bottles, clothes and shoes that are old and torn, used stationary items including pens with plastic bodies, rulers, sharpeners, pencils made of wood, glass bottles, etc.
It is important to understand that not all of these items will decompose and disappear, if we dump them into the earth. All resources can be classified into two types, based on this factor of decomposition, i.e. biodegradable and non-biodegradable. Thus, it is essential for us to segregate our waste materials and dispose them accordingly.
Such substances can be broken down into simpler substances by biological processes carried out by certain kinds of micro-organisms, and hence will decompose eventually. Examples of biodegradable wastes include natural substances such as vegetable peels, tea leaves, stale food, cotton, woolen or silk clothes, etc.
These substances cannot be broken down by the action of certain bacteria and other micro-organisms and do not get decomposed easily. Heat and pressure do affect such substances, however, they take a lot of time to decompose and harm the eco-system.
