Reports indicate that factors such as weakened environmental regulations in some areas and a growing global demand for agricultural products are contributing to the rise in deforestation.

The Amazon acts as a massive carbon sink, storing billions of tons of carbon. Its transpiration also influences regional and global rainfall patterns.

The vast majority of deforestation in the Amazon is driven by the clearing of land for cattle ranching and the cultivation of soy, which are major global commodities.

While green hydrogen can be used for power generation and potentially some forms of transportation and industrial processes, its direct application for widespread residential heating and cooking is less common compared to other cleaner alternatives like electricity or biogas.

The mission is a key strategy for India to reduce its carbon footprint and work towards its national and international climate goals, including achieving net-zero emissions.

The high capital cost of electrolyzers, which are essential for producing green hydrogen, and the significant investment required for storage and transportation infrastructure are major hurdles.

The mission's core objective is to establish India as a leader in the global green hydrogen market, fostering production and export capabilities.

Green hydrogen is produced by splitting water molecules (H2O) into hydrogen (H2) and oxygen (O2) through electrolysis, powered by electricity generated from renewable sources like solar and wind.

The development of bio-concrete involves understanding material properties (material science) and the biological requirements for coral growth and settlement (marine biology).

The analogy 'rainforests of the sea' is used for coral reefs because of their exceptionally high biodiversity, supporting a vast array of marine life.
