Reasons for Conservating Biodiversity
There are various reasons for conservation of biodiversity. These can be grouped as:
(i) Narrowly Utilitarian Arguments
(a) Humans derive several direct economic benefits from nature such as food (cereals, pulses and fruits), firewood, fibre, construction material, industrial products (tannins, lubricants, dyes, resins and perfumes) and products of medicinal utilities.
(b) More than 25% of drugs sold today are derived from plants and about 25,000 species of plants are used by native people as traditional medicines.
(ii) Broadly Utilitarian Arguments
(a) Biodiversity plays a major role in many ecosystem services that are provided by nature.
(b) Some of them are:
Production of oxygen Amazon forest is estimated to produce, 20% of the total oxygen in the atmosphere through photosynthesis.
Pollination Ecosystem provides pollinators like bees, bumblebees, birds and bats.
Aesthetic pleasures like walking through thick woods, watching spring flowers in full bloom or waking up to koel or bulbul’s song in the morning.
(iii) Ethical Reasons
(a) Every species has an intrinsic value, even if it may not be of current or any economic value to us.
(b) We have a moral duty to care for their well being and pass on our biological legacy in good order to future generations.
