what are the most common c0vId vaccine myths and how did they start? Explain your answer.
Answer:
The most common myths are:
- C0vid2019 vaccines cause autism
- C0vid2019 vaccines may modify your DNA
- C0vid2019 vaccines are unsafe
Explanation:
The most common myths associated with C0vid2019 vaccines are:
1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.
2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response
- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).

Describe what a sustainable ecosystem looks like with a real-life example
Answer:
The Appalachian Region in the southwestern United States, which is one of the most richly biodiverse regions in the world. Overall, cities that recycle & reuse basically exist in harmony with the surrounding environments are also considered sustainable ecosystems. A sustainable ecosystem is one where even when things are taken, nature still has enough to function and the ecosystem/area is healthy. But dealing with domestic, industrial, & agricultural waste is a growing environmental issue. That is NOT a sustainable ecosystem.
