Climate change is a serious matter of concern as it directly or indirectly affects the quality and quantity of food that we eat. According to the recent scenario the projected population of earth in 2050 will be 8.75 billion hence we need to double up our recent food production. It is indeed the great challenge for our policy makers how they would be able to feed such large population with that limited resources .climate change is a culprit behind destruction of biodiversity as it reached at threshold level where species failed to show resilience. Food production is directly or indirectly related to our biodiversity. It is well established fact that entire food in this world comes from roughly 124 varieties of plants out of which 70 percents are directly dependent on pollination. According to the proceedings of national academy of science journal if greenhouse gas emission will remain same for next 50 years then one out of three species of plant, animal, bird will wipe out and remaining to will also at extreme danger according to the report with every 0.5 degree increase in temperature there will be 50% of the local extinction or death of the species. By taking view of recent trend of increasing greenhouse gases there will be 2.9 degree increase in temperature of earth by 2070 and as the result the world will lose 95% of specie of present biological resource.
Let us consider an example of specie which is strongly affected by climate change e.g. Bumble bee. Bumble bees are world most efficient pollinators they are responsible for the proper size of melon, tomato, potato, berry and raspberry. They are called as the master of buzz pollination because they have bigger size as compared to other bees and they do methodological browsing According to the data gathered in 2001-2004 there was 17% percent decline in the population of bumble bee and 46% decline in their population in North America. The reason behind their population decline is Climate change as temperature in these areas increased by 1.5”C. Climate change also responsible for the reduction in the quantity of cacao tree also known as chocolate plant. Ingredients such as xylobromine, theobromine and methylxanthine present in cocoa powder are also used in the production of medicine of asthma. If we lost our entire cacao tree then we will have to find an alternative for medication that we are preparing using chocolate plant.
Another example is specie named as black and white ruffed lemur they are called as large body natural seed dispersers in forest. Climate change causes decline in their population by 49% and reports are suggesting that lemur will be completely wipe out by 2075 from the world. With their extinction there are chances of increase in the rate of deforestation which is also a very serious concern. There are many more examples present where we can see climate change as a reason for lowering our food production by damaging biodiversity time has come to do something for our mother earth as it’s the only home we have for ourselves and for our future generation. Anthropogenic activities are all responsible for these circumstances. We need to tackle this right now or the time will not give us second opportunity. Sustainable development goals presented by United Nations have goal no 13 as climate action which is specified to every nation present in this world that if we want sustainability then we need to take action and how we can take actions we need to fight our own egos in order to bring the world to normal as it’s our ego and greed which makes our minds paralyzed we can only think of ourselves as we are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock.
This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. The main driver of climate change is the greenhouse effect. Some gases in the Earth’s atmosphere act a bit like the glass in a greenhouse, trapping the sun’s heat and preventing it from going back into space and causing global warming. Many of these greenhouse gases occur naturally, but human activity is increasing the concentrations of some of them in the atmosphere, in particular methane carbon dioxide, fluorinated gases, nitrous oxide. CO2 produced by human activities is the largest contributor to global warming. By 2020, its concentration in the atmosphere had risen to 48% above its pre-industrial level (before 1750). Other greenhouse gases are emitted by human activity in smaller quantities. Methane is a more powerful greenhouse gas than CO2, but has a shorter atmospheric lifetime. Nitrous oxide, like CO2, is a long-lived greenhouse gas that accumulates in the atmosphere over decades to centuries. but it’s do or die right now .either we can follow that quote “Do Good Have Good” or else we need to get ready to face more serious implications caused by climate change to our lives like it is very much clear that we can only survive if we will have food to eat and clean water to drink but looking at the recent stats if trend goes same way time will come when we will only left with regrets. We need to join hands to fight this out as it’s the only option we have right now
