List two of the myths that you found most intriguing and write the reasons why you find them interesting. Outline the myth using your own words and explain the scientific fact about the issue.
One of the fantasies that I found most fascinating is the fantasy that an unnatural weather change is brought about by the sun. This legend is intriguing on the grounds that it is a typical misinterpretation that the sun is the essential driver of an unnatural weather change.
In actuality, the sun is just liable for around 25% of the warming that has happened since the modern transformation. The other 75% is because of human exercises like consuming
petroleum products, deforestation, and different exercises that discharge ozone depleting substances into the climate.
Another fantasy that I found fascinating is the legend that an Earth-wide temperature boost isn't occurring. This fantasy is intriguing in light of the fact that it is a typical misguided judgment that an unnatural weather change isn't genuine or that it isn't working out. Actually, a dangerous atmospheric devation is going on and is brought about
by human exercises.
The proof for this is overpowering, with temperatures climbing, ocean levels rising, and outrageous climate occasions turning out to be more successive. The logical truth is that a
dangerous atmospheric devation is occurring and is brought about by human exercises.

Which substances cause ozone depletion? Please explain and discuss their effect on climate change. Use sources/citations to support your work.
Which substances cause ozone exhaustion? Ozone consumption is brought about by different substances, including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, and methyl bromide. These substances are alluded to as ozone-
exhausting substances (ODSs). (Joined Countries Climate Program, 2018).
Chlorofluorocarbons (CFCs) are a gathering of synthetic compounds that contain chlorine, fluorine, and carbon. They are utilized in different items, including spray showers, refrigerants, and solvents. CFCs are delivered into the environment when these items are utilized and when they are discarded inappropriately. CFCs are truly steady in the climate and can stay there for as long as 100 years. At the point when CFCs arrive at
the stratosphere, they are separated by bright radiation, delivering chlorine iotas. These chlorine iotas then respond with ozone particles, separating them and causing ozone consumption. (Joined Countries Climate Program, 2018).
Hydrochlorofluorocarbons (HCFCs) are a gathering of synthetic compounds that contain hydrogen, chlorine, fluorine, and carbon. They are utilized in various items, including refrigerants, spray fuels, and froth blowing specialists. HCFCs are delivered into the air when these items are utilized and when they are discarded inappropriately. HCFCs are less steady in the air than CFCs and can stay there for as long as 15 years. At the point when HCFCs arrive at the stratosphere, they are separated by bright radiation, delivering chlorine iotas. These chlorine iotas then, at that point, respond with ozone particles, separating them and causing ozone exhaustion. (Joined Countries Climate Program, 2018).
Halons are a gathering of synthetic compounds that contain bromine, fluorine, and carbon. They are utilized in various items, including fire dousers and fumigants. Halons are delivered into the climate when these items are utilized and when they are discarded inappropriately. Halons are truly steady in the air and can stay there for as long as 10 years. At the point when halons arrive at the stratosphere, they are separated by bright radiation, delivering bromine molecules.
Methyl bromide is a synthetic that contains bromine and carbon. It is utilized in various items, including fumigants and pesticides. Methyl bromide is delivered into the environment when these items are utilized and when they are discarded inappropriately. Methyl bromide is entirely steady in the environment and can stay there for as long as 10 years. At the point when methyl bromide arrives at the stratosphere, it is separated by bright radiation, delivering bromine molecules.

Compare the environmental impacts of waste in rural and urban settings. Use sources/citations to support your arguments.
The ecological effects of waste in rustic and metropolitan settings can shift extraordinarily. Squander the board is a significant piece of both country and metropolitan settings, and the manner by which waste is overseen can essentially affect the climate. In country settings, squander is frequently discarded in landfills, which can prompt soil and water tainting, air contamination, and other ecological issues. In metropolitan settings, squander is frequently discarded in incinerators, which can likewise prompt air contamination and other ecological issues.
In country settings, squander is frequently discarded in landfills, which can prompt soil and water tainting. Landfills are in many cases situated in provincial regions, and the waste that is discarded in them can drain into the dirt and water, defiling them and prompting wellbeing and natural issues. Furthermore, landfills can create methane, a strong ozone depleting substance, which can add to environmental change. In metropolitan settings, squander is frequently discarded in incinerators, which can
likewise prompt air contamination. Incinerators produce air contaminations like particulate matter, sulfur dioxide, and nitrogen oxides, which can prompt wellbeing and natural issues. Also, incinerators can deliver dioxins, which are exceptionally poisonous and can cause wellbeing and natural issues.
In both country and metropolitan settings, waste can likewise prompt other natural issues.
For instance, in the two settings, waste can draw in vermin, for example, rodents and bugs, which can spread illness and sully food sources. Moreover, in the two settings, waste can draw in birds and different creatures, which can prompt the spread of sickness and the annihilation of living spaces.
To diminish the natural effects of waste in both country and metropolitan settings, executing successful waste administration strategies is significant. In country settings, this can incorporate the utilization of fertilizing the soil and reusing, as well as the utilization of biodegradable materials. In metropolitan settings, this can incorporate the utilization of incinerators and waste-to-energy plants, as well as the utilization of treating the soil and reusing. Furthermore, instructing general society about the significance of appropriate waste administration and the possible ecological effects of ill-advised squander management is significant.
All in all, the natural effects of waste in country and metropolitan settings can differ extraordinarily. In the two settings, it means a lot to execute powerful waste administration systems to decrease the natural effects of waste. Also, instructing the general population about the significance of legitimate waste administration and the possible natural effects of ill-advised squander management is significant.
