D Correct answer
Explanation

Deforestation means the felling and clearing of forest cover or tree plantations in order to accommodate agricultural, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose. Deforestation can also be seen as removal of forests leading to several imbalances ecologically and environmentally. Synthetic products are materials that are made by chemical processes that are formed artificially by chemical synthesis such as plastic bags, chairs, toys, etc. These synthetic materials can last for years and cannot be decomposed by decomposers. These synthetic products like different plastic products are made up of plastic; this creation of man hinders the flow of materials in the biosphere. Improper disposal is one of the reasons why synthetic products become of the problems and causes of ecological imbalance. It destroys ecosystem that can kill the organism and at the same time it causes various problems in the living world such as pollution.

Therefore, the correct answer is option D.
