1. Broadly utilitarian arguments
• Biodiversity plays a major role in maintaining and sustaining supply of goods and services from various species as well as ecological systems.
• The different ecological services provided are:
a. Amazon forest is estimated to contribute 20 per cent of the total oxygen in the atmosphere on earth.
b. Ecosystem provides pollinators like bees, bumble bees, birds and bats which pollinate plants to form fruits and seeds.
c. Aesthetic pleasures like bird watching, spring flowers in full bloom, walking through the thick forest, waking up to a bulbul’s song, etc. are some other benefits of the ecosystem.
2. Ethical reasons
• There are thousands of plants, animals and microbes on this earth which are not useless. Every one has some intrinsic value even if it is not of any economic value to us.
• It is, therefore, our moral duty to ensure well-being of all the living creatures for the utilisation of future generations.
