HUMAN CAUSES OF GLOBAL WARMING AND THEIR EFFECTS ON MOTHER EARTH

In the past few decades, the issue of changing global climate has been transformed into a dilemma. The primary way human contributes to this global warming is by burning fossil fuels. This combustion of fuels leads to increased amount of carbon dioxide emitted in the atmosphere, which in turn leads to increased Greenhouse Effect. Of course, the more energy used, the more greenhouse gases are emitted; the more humans cause global warming. Perhaps, it is rightly quoted “No animal has contributed to global warming as significantly as man has.” Some of the chief activities that contribute to the global warming are:

 

When You Drive

A large portion of carbon emission is attributed to the burning of gasoline in engines of vehicles. The combustion of gasoline releases nitrous oxide too, which is again a greenhouse gas.

 

When You Eat Meat and Exotic Foods

Eating food that is shipped long distances, adds to greenhouse gas emissions as it travels over 1000 miles before reaching you. Eating beef and drinking milk also adds to greenhouse gases, since cows emit significant amounts of methane, a greenhouse gas even more efficacious than carbon.

Land conversion

When farms and forests disappear, the land loses the ability to absorb greenhouse gases, and emissions from other activities have an even greater effect.

 

Increasing temperature of the Earth

 

The reason why we remain concerned about the above mentioned situation is that the effects of global warming on our earth are devastating. The prominent effects include:

  • Rising temperature
  • Drying of the rain forest
  • Melting of the glaciers
  • Increased sea level
