Oil spills, accidental leaks and the dumping of waste materials have also contributed to damage being done to wildlife. Due to all the reasons above, many species have come close to extinction and many more are likely to face a similar fate if we do not reduce the amount of damage we are doing to this planet in the future.
Global Warming As we touched on earlier, a huge portion of climate change or global warming can be attributed to our reliance on industrial activities over the years.
Global Warming can lead to: Rising sea levels. Risk of species of animals becoming extinct. An increase in tsunamis, typhoons, hurricanes, floods and other natural disasters. Melting of the ice caps Furthermore, our very existence as human beings could be under threat too, not to mention the increased risk of us catching diseases such as cholera, malaria and Lyme Disease.
We see that, globally, agriculture is the largest contributor to methane emissions. Rice production is also a large contributor to methane emissions. Aside from agriculture, fugitive emissions produce a significant amount of methane. This can happen when gas is transported through poorly maintained pipes, for example. Waste is third largest contributor.
Methane is produced in landfills when organic materials decompose. In this chart we show the per capita breakdown of methane CH 4 emissions by sector. Nearly all of our nitrous oxide N 2 O emissions come from agriculture, as this chart shows.
Nitrous oxide is produced by microbes in nearly all soils. But the application of nitrogen fertilizers makes much more nitrogen readily available for microbes to convert to N 2 O — this is because not all of the applied nutrients are taken up by crops. As the application of nitrogen fertilizers has rapidly increased over the past 50 years in particular, N 2 O emissions have also increased.
But nitrous oxide is not only produced when synthetic nitrogen fertilizer is applied; the same processes occur when we use organic fertilizers such as animal manure.
In this chart we show the per capita breakdown of nitrous oxide N 2 O emissions by sector. There are four key elements to consider when trying to quantify food GHG emissions. These are shown by category in the visualization:. Livestock — animals raised for meat, dairy, eggs and seafood production — contribute to emissions in several ways. Manure management, pasture management, and fuel consumption from fishing vessels also fall into this category.
They are the direct emissions which result from agricultural production — this includes elements such as the release of nitrous oxide from the application of fertilizers and manure; methane emissions from rice production; and carbon dioxide from agricultural machinery. Food processing converting produce from the farm into final products , transport, packaging and retail all require energy and resource inputs.
Food waste emissions are large: one-quarter of emissions 3. Durable packaging, refrigeration and food processing can all help to prevent food waste.
Reducing emissions from food production will be one of our greatest challenges in the coming decades. Unlike many aspects of energy production where viable opportunities for upscaling low-carbon energy — renewable or nuclear energy — are available, the ways in which we can decarbonize agriculture are less clear.
We will need a menu of solutions: changes to diets; food waste reduction; improvements in agricultural efficiency; and technologies that make low-carbon food alternatives scalable and affordable. It all comes at an environmental cost. Joseph Poore and Thomas Nemecek , in their large meta-analysis of global food systems, published in Science , estimated how much of our greenhouse gas emissions come from wasted food.
In the visualization here I show the emissions from wasted food in the context of global greenhouse gas emissions. Sector by sector: where do global greenhouse gas emissions come from?
Emissions come from many sectors: we need many solutions to decarbonize the economy. Energy electricity, heat and transport : Machinery 0. Transport: Rail 0. Energy use in buildings: Unallocated fuel combustion 7.
