Give reasons for the following:

(a) We should avoid using plastics.

(b) Radioactive wastes are hazardous.

(c) Open dumping is not an environment friendly method of managing waste.

(a) Use of plastics should be avoided because they are non-biodegradable. The carbon bonds in plastic cannot be broken down physically or chemically, requiring incineration, recycling, or landfill disposal.

(b) Radioactive wastes are hazardous due to their long-lasting radiation that can cause severe health effects, such as cancer and genetic mutations, and their potential to contaminate the environment for extended periods, posing risks to ecosystems and future generations.

(c) Open dumping is environmentally unfriendly as it leads to pollution of air, water, and soil, posing health risks to humans and wildlife, and contributes to the spread of diseases. It also hinders recycling efforts and promotes the inefficient use of resources.
