Dichlorodiphenyltrichloroethane (DDT), plastic materials, heavy metals...
Explanation:
DDT, plastic materials, heavy metals etc. are all substances that do not degrade naturally and persist in the environment for a long time. These substances are classified as non-degradable by natural processes. Let's understand this in detail.
What are non-degradable substances?
Non-degradable substances are those which do not break down or degrade naturally in the environment. They persist for a long time and accumulate in the environment causing harm to living organisms. Some common examples of non-degradable substances are DDT, plastic materials, heavy metals, radioactive waste etc.
Why are non-degradable substances harmful?
Non-degradable substances are harmful for the following reasons:
- They persist in the environment for a long time and accumulate in the soil, water and air.
- They are toxic to living organisms and can cause harm to their health and well-being.
- They can also enter the food chain and affect the entire ecosystem.
Why are some substances non-degradable?
Substances are non-degradable because they are not easily broken down by natural processes such as sunlight, water, air, microorganisms etc. Some substances are designed to be non-degradable for specific purposes such as plastic materials which are used for their durability and resistance to degradation. However, their non-degradability also makes them harmful to the environment.
Conclusion:
Non-degradable substances are harmful to the environment and living organisms. It is important to reduce the use of such substances and find alternatives that are degradable or can be recycled. Governments and industries should take steps to regulate the use and disposal of non-degradable substances to protect the environment and human health.
