Facts:

  • WRI estimates that the global demands for beef may increase by a whopping 95% by the year 2050.
  • There are 1.3 billion cattle across the world today (and India rears 300 million of them).
  • We would need over 2.6 billion cattle 30 years from now!

WRI Report:

  • The World Resources Institute (WRI), based in Washington, DC, USA, has recently suggested that people should reduce (if not abandon) eating beef
  • This is despite the fact that beef-eating in the US has dropped, due to health concerns about eating “red meat.”
  • Word cattle here includes cows and bulls, buffaloes, horses, sheep and goats – in effect farm animals.
  • Need of pastures: Breeding cattle impacts the climate conditions on earth, contributing to global warming. It also takes up lot of land for pasturing (it is estimated that 25% of the earth’s land mass (minus the Antarctica) would be needed for pasture).
  • Water intensive: It is also estimated that a third of the global water is needed for farm animal production .
  • Greenhouse Gases: On top of this, cows, buffaloes, sheep, goats and other “ungulates” belch a lot; this alone emits enormous amount of greenhouse gases that contribute over 60% to global warming.
  • In contrast, plants such as wheat, rice, maize, pulses, roots and tubers need no pasture land, demand far less water and, more importantly, generate little or no “greenhouse gases”.
  • We have promised to cut down global warming to no more than 1.5°C within the next 20 years, but with the projected demand for increase the number of cattle, the situation can only worsen.
  • Overeating: Today about 20% of the world overeats, leading to obesity and being overweight, and there are consequent health problems.
  • Cutting the calories down to the optimal level will lead to both health benefits and saving in land and water use.
  • Include more plant-based proteins and cut down animal-based ones. Traditional Mediterranean diet (fish and poultry meat, at low levels) and vegetarian meals (with legumes-based proteins) are suggested.
  • Reduce beef consumption specifically – Cutting down beef (cattle in general) in daily diet will offer both dietary and environmental benefit. The environmental benefits are clear; it saves agriculture for land use and reduces greenhouse gases. Rather than beef, one can turn to pork, poultry, fish and, of course, legumes.
  • History: The move to vegetarianism, which started around 1500-500 BCE by the Indians and the Greeks, was connected with the idea of nonviolence towards animals, and promoted by religion and philosophy. The Tamil scholar-poet Thiruvalluvar, the Mauryan kings Chandragupta and Ashoka, and the Greek sage Pythagoras (of the theorem fame) were vegetarians.

What are ‘Tipping points’?

‘Tipping points’, are essentially the  thresholds beyond which the earth’s systems are no longer able to stabilise.  

The danger in crossing tipping points becomes higher with more warming.

Such tipping points include: 

  1. melting of Greenland ice, 
  2. collapse of Antarctic glaciers (which would lead to several metres of sea level rise),
  3. destruction of Amazon forests, 
  4. melting of all the permafrost and so on.

About Report:

  • Published by World Wide Fund for Nature(WWF)
  • It is published every 2 years

 

Highlights of report

  • Soil Biodiversity: 
    • It encompasses presence of micro-organisms, micro-fauna (nematodes and tardigrades for example), and macro-fauna (ants, termites and earthworms).
    • Millions of microbial and animal species live and make up soils, from bacteria and fungi to mites, beetles and earthworms. Soil biodiversity, thus is total community from genes to species, and varies depending on environment.
    • The immense diversity in soil allows for great variety of ecosystem services that benefit species that inhabit it, the species that use it and its surrounding environment.
  • WWF’s ‘risk index’ for globe:
    • It indicated threats from loss of above-ground diversity, pollution and nutrient over-loading, over-grazing, intensive agriculture, fire, soil erosion, desertification and climate change.
    • India was coloured red on atlas and is among countries whose soil biodiversity faces the highest level of risk. Other countries in this category include Pakistan, China, several countries in Africa and Europe, and most of North America.
  • India’s per capita ecological footprint: It was less than 1.75 hectares/person (it is in lowest band among countries surveyed). India’s high population made it vulnerable to ecological crisis, even if per-capita consumption remained at current levels.
  • Pollinators: 150 million bee colonies were needed to meet the pollination requirements of about 50 million hectares of agricultural land in India, only 1.2 million colonies were present.
  • Ecological loss: Population of fish, mammals, birds, amphibians and reptiles has dwindled by average of 60% from 1970 to 2014 and fresh-water species have declined by 83% in same period. Globally, extent of wetlands os estimated to have declined by 87% since 1970.

United Nations Intergovernmental Panel on Climate Change (IPCC) has released special report on global warming in Incheon, South Korea.

Key Points from report

  • It clearly shows how half degree of warming makes big difference, adversely impacting global population and overall ecosystem through intense heat waves, melting of Arctic, sea level rise, erratic rainfall, reduction of farm yield and vanishing of living species.
  • It is possible to meet new warming target, provided nations together take rapid and far reaching transitions over next 10 to 20 years in energy, industry, land use, buildings, transport and cities to cut emissions and reach net zero around 2050 — 25 years earlier than planned under earlier 2-degree goal.
  • It lists four pathways to curb global warming and through which the 1.5 degree target can be achieved. In each of pathways, global average temperature is projected to overshoot 1.5 degrees Celsius target by some amount before returning to that level before the end of this century.
  • Each of these pathways is also dependent on some amount of Carbon Dioxide Removal (CDR), a reference to physical removal of stock of CO2 from atmosphere to reduce its concentrations. Varying amounts between 100 to 1000 gigatons (billion tonnes) of CO2 needs to be removed from atmosphere in these four pathways.
  • It refers to climate models that project robust differences in regional climate characteristics between present-day and global warming of 1.5 degrees Celsius and between 1.5 and 2 degrees Celsius.
  • These differences include increase in mean temperatures in both land ocean regions, hot extremes in most inhabited regions, heavy precipitation in several regions and probability of drought and precipitation deficits in some regions.

Advantages of keeping global temperature rise within 1.5 degrees Celsius

  • It also lists several specific advantages of keeping the global temperature rise within 1.5 degrees Celsius from pre-industrial levels.
  • By 2100, global sea level rise would be 10 cm lower with global warming of 1.5 degrees compared with 2 degrees Celsius.
  • Arctic Ocean free of sea ice in summer would be once per century with global warming of 1.5 degrees, compared with at least once per decade with 2 degrees Celsius.
  • Coral reefs will decline by 70-90% with global warming of 1.5 degrees, whereas virtually all (over 99%) would be lost with 2 degrees Celsius.
  • It also points out that climate-related risks to health, livelihoods, food security, water supply, human security and economic growth are projected to increase with global warming of 1.5 degrees Celsius and increase further with 2 degrees Celsius.

Finding 1:

  • Pollution in Northern and Western Indian may slow down the monsoon.
  • How?
    • The Indian summer monsoon season begins when the land surface becomes hot enough to drive a powerful rising motion of air in the atmosphere, producing heavy precipitation.
    • Cooler, humid air over the Arabian Sea flows inland to compensate for the rising air.
    • Air in this compensating circulation encounters the surface heating and also rises, perpetuating the cycle.
    • At the smallest scales, an increase in tiny particles in the atmosphere can shade the land surface while absorbing sunlight aloft, causing a reduction in the heat that reaches the surface.
    • Clouds that do form in these polluted environments are less likely to rain and more likely to persist because the droplets are smaller. These longer-lived clouds further cool the surface and weaken the circulation.
    • In this way more air pollution can mean weakening of monsoonal systems.

 

Finding 2:

  • Erratic behaviour of monsoon rainfall, including phenomenon of concentrated heavy rainfall on small number of days in localized area can be attributed to the rising air pollution, especially the increase in suspended particles in the atmosphere. 
  • How?
    • Excess aerosols, suspended solid particles like dust, smoke and industrial effluents in atmosphere is changing cloud patterns, its shape, size and other properties like temperature, which in turn is resulting in variability in rainfall over Indian sub-continent during monsoon season.
    • Aerosols are extremely important for cloud formation.
    • In absence of aerosols, no clouds can be formed and consequently no rainfall will take place.
    • But due to increase in aerosol content in atmosphere, there is direct consequence of rising air pollution interfering with stable cloud formation system and influencing rainfall patterns.
    • In short term, these changes in cloud structure and cloud dynamics lead to sharp variability in rainfall, which is similar to rainfall patterns witnessed very often in India in last few years.
    • In the long term, it is likely to lead to overall suppression of rainfall during the monsoon season.
