Electromagnetic Waves
Electromagnetic waves are made up of electric and magnetic fields of various intensity that emanate from natural and artificial sources. They include gamma rays, infrared, visible light, and X-rays. Electromagnetic waves travel through anything; air, liquids, solids, and vacuum. According to Someda (2017), this phenomenon differentiates them from mechanical waves such as sound and water waves, which require a medium to travel. Electromagnetic radiations (EMRs) are beneficial in telecommunication and biomedical devices. Telecommunication devices such as mobile phones, television, and computers have offered revolutionary effects in terms of communication at any time and anywhere in the world. EMR is applied in imaging studies like angiography and radiography, which enables healthcare professionals to scan the body for medical reasons. Someda (2017) argues that despite these benefits, the EMR from telecommunication and biomedical devices may cause health problems such as cardiovascular diseases, hearing disruptions, skin diseases, and depression.
Coronal Mass Ejection
A coronal mass ejection (CMC) is a large cloud of gas and magnetic fields that is blown away from the sun during long-duration solar flares. Coronal mass ejections are uncommon during solar minimum when the sun is not active. Research indicates that there might be only one coronal mass ejection weekly (Kay et al., 2019). Coronal mass ejection can become very common during solar maximum when the sun’s activity is very high. The Earth rarely experiences corona mass ejections effects; however, when they occur, they cause a geomagnetic storm that disrupts telecommunications, GPS signals, and electricity. Nobody can stop coronal mass ejections from happening; however, scientists can forecast when how powerful these flares occur. This knowledge will help me prepare for the disaster well by having an emergency kit, proper medical supplies, clean water, and non-perishable foods.
Colonize the Moon and Other Planets or Not
Colonizing the moon or other planets is a debate that has existed for a long time for human habitation. The world is literally burning, especially in Amazon, California, and Indonesia (Patz et al., 2014). Ice caps are melting, and many species are dying around the globe. The problems we the Earth is facing at the moment are all human-made, poisoning of water systems, air, and creation of mass desertification. Research has shown that the moon and other planets such as mars are not readily habitable. Firstly, humans will require understanding how to extract clean water, create oxygen, and create new clothing to deal with far more extreme conditions than the one we are facing. There will be need to learn new farming methods, new fuels and mode of transportation. NASA and other space programs require large sums of money to explore the space. The scientists can utilize the funds to solve problems the Earth is facing at the moment like climate change and make it more livable rather than colonizing the moon and other planets.
Mission to Mars
The mission to Mars is with the promise of scientific discovery. However, if there was to be an opportunity for me to go to mars or any other planet, I will decline it. Science has already shown that there are harsh climate and gravity, which may keep humans stuck on the surface (Billings, 2019). I would not want the isolation of my friends and relatives on Earth and face severe challenges like unfriendly temperatures and lack of water.
Understanding Climate Change
Climate change has destabilized the Earth’s temperature and is the main threat to biodiversity globally. Patz et al. (2014) state that climate is directly linked with the amount of carbon dioxide in the atmosphere that causes the ‘greenhouse effect.’ Climate change is bad for the health of humans since it causes rising temperatures, reduces air quality and extreme weather. Farmers depend on climate for food production. However, climate change causes droughts and floods, which affect harvests significantly. Research on climate change to understand it should be made an urgent matter of priority to solve climate-related extinctions.
