When prevention of climate change is uncertain, preparation is necessary .
Climate change continues to cause unusual and unpredictable weather around the world.
Longer drought, flooding, major stroke, snowfall, temperature extreme will increase earth’s temp upto 3-4 ‘C.
Rising CO² level and warmer earth means plant will grow bigger (more surface area of leaves) and thus plant consume more water.
Thus, we face water scarcity.
Smog contain Ozone particles and causes various problems – asthma, heart disease, skin cancer etc.
Plant sciences is the study of plants in all their forms and interactions using a scientific approach.
California’s Almond Orchard:-
In the past, for removing and disposing of the old trees we burn them in the field. But now Old trees are ground, chipped and turned back into soil before New almond tress are planted.
It help almond orchard to be more sustainable and resilient to drought and also increasing carbon content in soil.
Whole orchard recycling result compare to burned treatment :
1) Sequester 5 tons of carbon per hectare.
2) Increase water-use efficiency by 20 percent.
3) Increase crop yields by 19 percent.
scientists from the BBSRC managed to breed a new fast-growing broccoli that no longer relies on a period of cold weather to flower, and goes from seed to harvest in only 8-10 weeks. This discovery is especially relevant for broccoli, as it is flower buds that we eat.
Many terrestrial, freshwater, and marine species have shifted their geographic ranges, seasonal activities, migration patterns, abundances, and species interactions in response to ongoing climate change.
Increased carbon dioxide tends to suppress photo-respiration in plants.
- C⁴ plant adapt better for high CO² Concentration and photorespiration.
- It make 4 C sugar (OAA) thus fix more CO² and produce high amount of energy.
- It suited for hot dry climate.
- C4 plants include such low-latitude crops as maize, sorghum, sugar-cane, and millet, plus many pasture and forage grasses.
- Better adapt for photo oxidation. Prevent photooxidation due to kranz anatomy.
THE CLIMATE CRISIS HAS ALREADY BEEN SOLVED. WE ALREADY HAVE A FACTS AND SOLUTIONS . ALL WE HAVE TO DO IS WAKE-UP AND CHANGE – Greta Thunburg
