Consumption affecting the environment

Today, overpopulation is a serious issue in the world. To feed everyone, we need to make enough food. To make food, we have to cut down forests to make space for cattle and crops. This causes some species like tigers to become extinct because their habitat has been used by us humans. 

Also, many people drive cars, which release carbon dioxide. This is a chemical which influences the environment, causing global warming.

People use a lot of water; more than they actually need. This means that the groundwater levels are sinking and people are having trouble accessing water.

# not the most efficient way,
# but you get the idea.

str = "meow"

# convert string to binary
bin = str.bytes.map{|d| d.to_s(2)}.map{|b| b.rjust(8, '0')}.join
puts bin

# and convert it back to a string

1. Can you execute Ruby in the Chrome console? Why / why not?

Ruby cannot be executed in the chrome console. I am not exectly sure the technical reasons, but I would guess is that chrome does not have an inheret Ruby envirement to execute the code. This is why we had to create the envirement on our local computers.

2. Write some Ruby code that includes a method that fails to work solely because of a scope issue. Think about how Ruby scope differs from Javascript scope.

array = [1,2]

def add
  array[0]+array[1]
