“The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.” (NASA.GOV) Going through the history in our planet’s timeline, global warming seems to be an issue that is rising as time moves forward. People are more focused on materialistic things and are less worried with the planet. Not thinking about the future but only about what we are living in the present, we as human beings are considered selfish. Unfortunately, the imbalance that we are creating between our lives and earth is already showing the catastrophic signs in the form of cyclones, flood, tsunami, etc. If the imbalance continues to increase, one day the conditions will put a question mark on the existence of this planet. Several current trends clearly show that global warming is directly impacting the sea levels, the melting of ice caps and significant worldwide climate changes. “When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear.” (NRDC.ORG) In short, global warming represents a fundamental threat to all living things on earth. We need to start to think not only about ourselves and take action instead of pretending that nothing different is happening in the world that we are living in. Just to understand a little more about what is happening, “Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn. A forest to create pastures and plantations, carbon accumulates and overloads our...
