The first 12 matches of this summer's tournament have yielded 41 goals, over double the total (20) recorded in the first 12 matches of the 2010 competition in South Africa.
Brazil is in command of Group A after a controversial win over Croatia last Thursday, but Silva admits the goal rush has forced him to work even harder in training ahead of Tuesday's clash with Mexico.

"You have to have a good defense, it makes it difficult for the opponents," he told reporters.
"This is the World Cup for those who like goals, who like football. For a defender that’s not good, but it’s part of football. We worked well this week defensively to be able to neutralize our opponents.
"We have players who are ready and the front two score goals."
Silva was also full of praise for central defensive partner David Luiz, who completed a 50 million euro move from Chelsea to Paris Saint-Germain this summer.
"[David] Luiz is a player who makes us feel at ease," he added. "Aside from marking very well, he’s technically very strong and that makes us feel at ease. And that makes it easy for us to go out well with the ball.
"We’ve been doing that in training and Scolari has been encouraging him and Paulinho to come out from the back. Luiz allows us the possibility to pass the ball and for it to get to Fred properly."
One more victory would all but secure qualification for the knockout stages for Brazil, but Silva has warned his teammates against complacency when they take on Mexico.
"They’re top-quality players," he insisted. "I’ve played against them many times, especially at the Olympics. Unfortunately we lost [in the final] that day.
"Giovani [Dos Santos] and [Oribe] Peralta can decide a match in seconds, so we have to pay attention to their offensive actions."
