Environment & Ecology MCQs

The release of greenhouse gases from permafrost further warms the planet, leading to more permafrost thaw, creating a self-reinforcing cycle known as a positive feedback loop.

The thawing permafrost can release ancient viruses and bacteria that have been dormant for thousands of years.

Permafrost stores vast amounts of organic carbon, which upon thawing, decomposes and releases greenhouse gases like methane and carbon dioxide.

Permafrost is defined as ground that has remained frozen for at least two consecutive years.

Arctic amplification refers to the observed phenomenon where the Arctic is warming at a rate two to four times faster than the rest of the planet.

SDG 2 aims to end hunger, achieve food security and improved nutrition and promote sustainable agriculture. Agri-Net Zero directly contributes to this goal by promoting sustainable and resilient food systems.

The initiative is designed to offer a comprehensive package of support, including technical guidance, platforms for sharing best practices, and financial resources to facilitate the adoption of sustainable methods.

Methane (CH4) emissions in agriculture are primarily from livestock (enteric fermentation and manure management) and rice cultivation.

The initiative promotes sustainable practices. Increased use of fossil fuels would contradict the goal of reducing emissions and transitioning to net-zero.

The core objective of Agri-Net Zero is to drive the agricultural sector towards achieving net-zero greenhouse gas emissions.
