Water Footprint measures the amount of water used in producing a unit of goods/services that we use.

The water footprint per kg of animal products is generally higher than crop products. The water footprint of meat from beef cattle (15,400 litres/kg as a global average) is much larger than the footprint of vegetables which stands at 322 litres/kg (average).

The increase in production and consumption of animal products puts additional stress on the freshwater reserves. Especially in MENA (Middle East and North Africa) region, according to the World Bank, this region is expected to suffer an economic loss of 6-14% of GDP by 2050 from climate-related water scarcity.

According to the UN:- 

1) 2.3 billion people live in water-stressed countries, of which 733 million live in high and critically water-stressed countries.
2) 3.2 billion people live in agricultural areas with high to very high water shortages or scarcity, of whom 1.2 billion people – roughly one-sixth of the world’s population – live in severely water-constrained agricultural areas.
3) About 4 billion people, representing nearly two-thirds of the global population, experience severe water scarcity during at least one month of the year.

Human Development Index ( HDI ) 2021 measures the average achievement in three basic dimensions of human development—a long and healthy life, knowledge and a decent standard of living. The health dimension is assessed by life expectancy at birth.  The education dimension is measured by the mean of years of schooling for adults aged 25 years and more, along with expected years of schooling for children of school entering age.  The standard of living dimension is measured by gross national income per capita. The pandemic dealt a serious blow to human development worldwide. In the 2021 index, 90% of countries saw their HDI value drop. Only a third of very high HDI countries saw a decline in 2021 (compared with over 90% in 2020), whereas HDI scores of 60% of low, medium and high HDI countries declined.

  The World Press Freedom Index 2021 ranks 180 countries and regions according to the levels of freedom available to journalists. It provides an overview of the freedoms available to the media based on pluralism, independence of the media, quality of legislative framework and safety of journalists in a country or a region. Norway remains at the top for the fifth year in a row, followed by Finland. Germany came down from 11th spot to 13th spot and has been reclassified as "fairly good" and the United States was placed at the 44th spot. Brazil (111) and Russia (150) share the "bad" classification with India, placed at 142. China continues to be at the 177th spot with internet censorship, surveillance and propaganda at unprecedented levels.

China is the king of surveillance. At the end of 2021, an estimate by IHS Markit puts the number of installed surveillance cameras globally at over a billion, and more than 50% of it in China. An analysis by Compatitech shows that around 540 million cameras were installed in China, which equates to an average of 372.8 cameras per 1,000 people. Densely populated cities like Shenzhen could have at least 6,220 cameras per square mile, followed by Wuhan with 5,429, and Shanghai with 4,323 per square mile. Indore, Hyderabad, Delhi, Chennai, Singapore, Moscow, Baghdad, London, St. Petersburg, and Los Angeles are the 10 most surveilled cities outside China.
