Can we reverse climate change?

Earth’s temperature would continue to rise for a few decades even if all human emissions of heat-trapping gases stopped today because ocean currents would release excess heat from deep within the ocean. The Earth’s temperature would stabilise once the excess heat radiates into space. Global temperatures would gradually begin to decline if no further human influence is exerted.

About one-third of our food doesn’t reach the plate. We waste a wide variety of resources each time food goes uneaten – seeds, water, energy, land, fertiliser, hours of labor, financial resources. Also, when organic matter is discarded, it emits methane, a powerful greenhouse gas. Approximately 8 percent of global emissions are caused by food waste, thus it is essential for us to reduce food wastage.

A majority of the world’s vehicles emit greenhouse gases, resulting from more than 1 billion cars on the road today. Making cars run on electricity as their fuel can dramatically reduce air pollution and make mobility more sustainable. The source of that electricity matters, of course. There is no question that electric vehicles (EVs) offer an emission advantage, but renewable-powered EVs are the real solution with 95 percent fewer pollutants than standard cars. We are heading in that direction, fortunately.  

Increasing bamboo planting is also an option. In addition, bamboo offers a means of reducing global warming. Carbon is sequestered by bamboo through photosynthesis more rapidly than any other plant, removing it from the air more quickly.  

“Reduce, reuse, recycle,” still rings true. Each of us contributes to climate change through our consumption and waste. As a result of recycling, new products can be developed from recovered materials that usually save energy.

In the current refrigeration system, emissions come from the disposal of refrigerants. Following their removal from the system and careful storage, refrigerants can either be purified to be reused or converted into other chemicals that do not cause warming. This is also essential for the reversing of climate change.

Carbon dioxide is released into the atmosphere when forests are destroyed, primarily because of agricultural expansion or urbanisation. It is estimated that tropical forest loss alone accounts for 16 to 19 percent of human-induced greenhouse gas emissions. The restoration of tropical forests, both passively and purposefully, has become increasingly popular in recent years. With the regrowth of forest ecosystems, trees, soil, leaf litter, and other vegetation absorb and hold carbon, preventing it from going into circulation and causing global warming.

All of us can solve the climate change problem, and doing so improves life on our planet for everyone. Thus it is of the utmost importance that we do everything in our power to make our planet greener.
