Since the beginning of mankind, human beings have come a long way. With the development of technology, a lot of improvements have been made to our lifestyle. However, along with these improvements, a lot of damage has been made and is still being made. One of the key factors that may result in our destruction and has become an increasing concern worldwide is global warming.
What is Global Warming?
A simple way of defining global warming is to say that it is the increase of the amount of heat trapped near the surface of the earth due to greenhouse gases such as carbon dioxide, methane, nitrous oxide and ozone gas.
Causes of Global Warming
A lot of human activities, such as the burning of fossil fuels, deforestation and improper disposal of materials, play a huge part in the rise of global warming. The ones who will chiefly have to face the dire consequences of the rising temperature are none other than us.
- The main cause of the rising temperatures is the burning of fossil fuel. With the population growing at a rapid speed, the demand for fossil fuels has been increasing. The burning of fossil fuels produce around 21.3 billion tonnes of carbon dioxide (one of the main greenhouse gases that contribute to global warming) a year.
- Along with fossil fuels, the demand for shelter and land has been increasing as well. To overcome the growing demand, deforestation takes place. Excessive cutting of trees releases carbon dioxide into the atmosphere and reduces the amount of photosynthesis, a process that allows plants to take in carbon dioxide from the atmosphere.
- The improper disposal of waste materials can lead to the emission of many greenhouse gases. The most significant of said gases produced from waste is methane, which is released during the breakdown of organic matter in landfills.
Effects of Global Warming
There is no argument on the matter that global warming will have an adverse effect on us. Here are some of the things that the increasing temperature will lead to:
- Melting of glaciers and swelling of seas – this can cause many low-lying coastal regions, such as our country Bangladesh, to get wiped off the map
- Rise of water temperatures – this can cause the oxygen dissolved in the water to get depleted
- Climatic changes – this can cause more extreme weather changes due to frequent and intense droughts, rainstorms, heat waves, rising sea levels and melting glaciers
- Increase in the breeding of insects – this can cause more insect-borne diseases
Ways to Prevent Global Warming
Though damage to the environment is inevitable according to our standard of living, steps have to be taken to create an optimum situation for us to have a healthy environment. Here are some simple habits we can incorporate into our daily lives to prevent global warming:
- Switch to green technology
- Reduce tropical deforestation
- Drive less
- Use public transport if vehicle is needed
- Recycle more
- Save energy
- Plant trees
- Use less hot water
- Reduce use of chemical fertilizers
- Spread the word and encourage others to conserve energy
While we are improving our lifestyles, we have to make sure that we are not overlooking all the damage that is being made. By being more aware about the consequences of our actions and by trying our best to do things in a way that may not damage the planet, we can help to create a better and safer place for the future generations.
