What causes it?
Human activities are the main contributers to the cause of global warming. Due to the pollution that is being pumped to the air across the globe, the levels of greenhouse gases in the atmosphere are increasing drasticaly. This causes the gases to form a layer in the atmosphere, that results of trapping heat radiation from escaping.When a molecoule of Carbon Dioxide is released into the atmosphere in remain there for 100 years.

Smokes from factories contribute to the increase of Carbon dioxide in the air. (Source: taken in Langa).
Therefore, global warming is something we human created ourselves by the way we choose we live our lives. Industralization is the main reason for this because countries that are based on industrialized economy are the biggest contibutors. The amount of carbon dioxide a country emits into the atmosphere depends mainly on the size of its economy, the level of its industrialization, and the efficiency of its energy use. In fact, the largest industrial powers, such as the US and EU are the biggest contibutors. They are responsible for 50% of all greenhouse gase emissions (2).
Even though developing countries contain most of the world's population, their industrial production and energy consumption per capita are relatively low. Thus at this point there seems to be little doubt that the primary responsibility for creating the risk of global warming lies with developed countries.
Our opinions
We think that as a country that is contributing less to the cause of global warming, those who are the main cause of global warming should reduce the burning of fossil fuel, start planting trees, stop build big buildings and choping trees for newspaper and toilet papers because its consiquences will not just affect them but also the whole universe.
We think that those countries who produce more greenhouse gases should be given a limite on what percentange of greenhouse gases that they should produce annualy.There should be a law that any country that is producing more than this limited percntange should be fined.
The first world countries are the the most contributing contries emitting the gases to the atmosphere and the poor countries are the most suffering.The nuclear power plants are one of major the contributers and they are importent because of the community benefits in terms employment and fighting poverty. The are flowers, however, serpents of the environment . Instead of nuclear power plants we must use hydro power stations they are harmless to every species on the planet.
