How many people are attacked each year by sharks?
Worldwide there is an average of 50-70 shark attacks every year. The number of attacks has been increasing over the decades as a result of increased human populations and the use of the oceans for recreational activity. As long as humans continue to enter the sharks' environment, there will be shark attacks.
Overview of the sizes and frequencies of meteorites hitting the earth's atmosphere
The rate of meteors by weight, coming in contact with with the Earth's atmosphere is termed meteor flux. The smallest particles, called micrometeorites, are a few microns in diameter and don't tend to burn or melt but slow and settle to the Earth's surface as dust. Meteors of a few centimeters or less tend to heat up and glow and appear as shooting stars but melt or evaporate before hitting the Earth's surface. Meteors of greater than a few centimeters are called meteoroids until impacting the Earth when they are termed meteorites.
...
Most of the mass of meteor flux is micrometeorites. Objects of 1 micron land on the Earth at a rate of over 2 million per minute. Meteorites of 1 mm reach the surface at about 2 per minute. An object of 1 meter in diameter impacts with the Earth about once a year. Larger meteorites, such as the Tunguska event in 1908 estimated at 20-60 meters in diameter, or Meteor Crater in Arizona estimated at 30 meters, occur about once in 5,000 to 10,000 years.
Catastrophic impacts of 1 kilometer diameter can occur about once in a million years. And a 10 kilometer object could impact every 100 million years. These are climate changing, mass extinction events like the Chicxulub impact event of 65 million years ago thought to be responsible for the extinction of the dinosaurs.
I think it is strange so many are being seen.

Before anyone gets all excited perhaps the increase in reports could be entirely to better tracking methods, more input locations, etc.

We are an organization of amateur and professional meteor scientists and observers founded in 1911, with a common goal of studying meteors: – bright fireballs, the annual meteor showers, and the random sporadic meteors that appear every night. It’s an exciting field where amateurs equipped only with their eyes can make valuable scientific observations.
